Release of PerfectPower Androïd 7.0.1 on Friday April 12, 2024 at 1.35 pm (New York time)

Release of PerfectPower Androïd 7.0.2 on Thursday April 25, 2024 at 9.27 am (New York time)

Release of PerfectPower Androïd 7.0.3 on Sunday May 5, 2024 at 11.51 am (New York time)

Release of PerfectPower iOS 6.0 on Sunday May 12, 2024 at 5.33 pm (New York time)

 

Note 1: Validation tests of PerfectPower iOS V6 were carried out on the road on Saturday May 11, 2024 by performing measurements in parallel with PerfectPower iOS V6 running on my iPhone 14 and PerfectPower Android V7 running on my Xiaomi MI 8 and... the results are once again spectacular with an incredible proximity of results between the two versions on each of the measurements performed, the report of this validation session will be published in the Results section on Friday May 24, 2024!

 

Note 2: A new PerfectPower Vs Dynos comparison carried out on Tuesday May 14, 2024 with PerfectPower iOS V6 by a PerfectPower iOS user on his own dyno with spectacular results: 0.7% difference in max power and 0.2% in max torque! AND a hell of a car with over 500 hp!

 

Note 3: To celebrate the launch of the V7 Androïd and V6 iOS versions, PerfectPower Android and iOS are both on sale at 33 euros & dollars from Thursday April 11 to Friday May 31, 2024!

 

Note 4: I am so certain of the perfection of the results of these V7 Androïd and V6 iOS versions AND of the impossibility of doing better in the context of power measurements with a simple phone (even smart!) that I launched on Wednesday, May 1, 2024 my famous friendly challenge at 10,000 euros & dollars!

 

Note 5: Many unforeseen events have prevented me from moving forward with the development of the next versions of PerfectPower iOS since the release of version 6.0 on Sunday May 12, 2024, and I apologize for this. I'll get back to it on Saturday May 25, 2024, and I will publish at that time a new forecast plan for the releases of these next versions.

 

Results section being updated on Thursday May 23 and Friday May 24, 2024 (all possible results recalculated with version V7 + publication by results and no longer by cars + new presentation format)

 

Inauguration on Wednesday March 27, 2024 of a new “New generation” website linked to this one:

 

www.perfectpower.pro

 

IMPORTANT: This website (www.perfectpower.pro) is NOT the PerfectPower official website, it is a complementary "New generation" style website intended to present PerfectPower in a synthetic, aesthetic, and user-friendly way! Moreover, it was only created today in two hours and it is still in full elaboration, especially on the filling of the sections of the home page located under the home slideshow, thank you for your understanding! And finally this website will be 100% English-speaking, the official website (www.perfectpower.ch) already being available in 3 languages (English, French, and Russian -well for the moment the translation into Russian is on standby-).

I) PerfectPower Androïd

 

 

Report of version 7.0.3 released on Sunday May 5, 2024 à 11.51 am (New York time)

 

1) Power / Mode 1 only: Addition in the power results sheets of the info "Speed at max rev" and an explanatory text on the "Max speed correction" function ideal in the event of poor GPS reception or failure of this one in this mode (indeed, 95% of the measurement accuracy is made by the accelerometer in this mode)

2) Power / Modes 1 and 2: Addition in the power results sheets of a “Miscellaneous” chapter and its first information: “Estimated tyre slip”

3) Fixed an oversight (non-deletion of internal logs after release of the V7.0.2) which could cause a crash when opening certain results

 

Report of version 7.0.2 released on Thursday April 25, 2024 at 9.27 am (New York time)

 

1) Power & Accelerations / Modes 1 and 2: Tiny optimization of the smoothing of curves, even cleaner but without any loss of precision

Note: This first modification was decided out of pure perfectionism!

2) Power & Accelerations / Mode 2 only: Specific but necessary slight increase in the smoothing of curves in mode 2 so with the RaceBox Mini

Note: On the other hand, this second modification was decided following insufficiently stable measurement results in mode 2 with the RaceBox Mini on a measurement road that was certainly not smooth at all but the RaceBox Mini was supposed to be insensitive to it ==> It is therefore obvious that additional fine-tuning had to be done in this mode 2 but this nevertheless reminds us that using only GPS data is in no way a miracle solution allowing us to measure anywhere and that we remain totally dependent on variations in the precision of the GPS signal throughout the measurements, EVEN with the best external GPS on the market, which is undoubtedly the RaceBox Mini...

BUT the most important thing is not that: the most important thing is to know that PerfectPower V7 has done the BEST work possible to obtain optimally precise measurement results in each of the two modes, and it proves it with the launch of a friendly but clear challenge at 10,000 euros & dollars!

 

Report of version 7.0.1 released on Friday April 12, 2024 at 1.35 pm (New York time)

 

1) Fixed an oversight distorting the calculation of wheels power for results of type "Incorrect average of version V6"

2) Improved measurement mode management:

- Added measurement mode to power results lists

- Specification of the measurement mode for each validated result in the power results comparison sheets

3) Aesthetic improvements:

- Fixed an oversight disrupting the display in cars and results lists in dark mode on some phones

- Wallpaper of cars and results lists in black (instead of white)

 

Report of version 7.0 released on Thursday April 11, 2024 at 6.11 pm (New York time)

  

Major evolution of the V7 version compared to the V6 version:

1) Ultimate and final optimization of the precision of power and acceleration measurements in modes 1 (Accelerometer + GPS) and 2 (GPS only)

A) Return to the signal processing techniques of versions V1 to V5, just deeply reworked and optimized!

Indeed, these techniques have the huge advantage of generating absolutely no lag in the curves, unlike that introduced in the V6 version, which caused a slight permanent delay resulting in a slight underestimation of maximum torques and a slight delay in maximum power and maximum torque revs...

B) Optimization of the curves smoothing, allowing both to faithfully reproduce the exact behavior of the engine (AND without any lag as explained above!), AND to completely destroy all disturbances (engine vibrations and "road disturbances" in the mode 1 "Accelerometer + GPS", and "GPS noise" in the mode 2 "GPS only")

C) Power only: Optimization of the detection of the exact point of end of measurement (rev limiter -on gasoline engine- or foot lift), allowing in one of the next versions 7.0.X the addition of the information "Estimated tyre slip"

D) Power only: Conservation and optimization of the system of variable smoothing of the curves depending on the signal / noise ratio (introduced in the V6 version, and allowing an optimal curves precision in all circumstances and the equalization of curves precision in 2nd and in 3rd gear), giving in comparison with the calibration carried out in the V6 version slightly "un-smoothed" curves 

E) Accelerations only: Removal of the system of variable smoothing of the curves depending on the signal / noise ratio (introduced in the V6 version), because it is unsuitable for acceleration measurements in gear change phases ==> Return to the fixed smoothing of versions V1 to V5 but optimized, giving in comparison with the calibration carried out in the V6 version significantly “un-smoothed” and much more realistic curves

F) Mode 2 (GPS only with use of the RaceBox Mini & Mini S) only: Resolution of a double (or even triple) points problem!

Indeed, the RaceBox Mini & Mini S is clocked at 25 Hz, but if in absolute terms it returns 25 information per second, in reality certain points are repeated two (or even three) times, which reduces its effective frequency (up to "only" 15 Hz!) and can obviously disrupt their correct processing, so here is what has been done:

- Search for all these "fake" double or triple points

- Clean re-calibration of measurement times and GPS speeds

Thus, PerfectPower can exploit the information from the RaceBox Mini & Mini S to its full potential, which is not quite that officially announced (25 Hz)...

2) Re-calculation and re-saving of all single (= individual) results saved in your phone during their first opening with this V7 version: thus, absolutely all your old measurements are converted in the blink of an eye to the new calculation system of the V7 version, exactly as if you had performed them directly with it!

IMPORTANT: It is therefore NORMAL to note that all your single results will change (the maximum powers will be approximately the same, but the maximum torques will slightly increase), but these are for sure the good AND final ones of the V7 version!

3) Specific management of all averaged results produced with version V6: as these results cannot be re-calculated with the new calculation system of version V7, they are kept as is and will therefore not change, but they are stamped " Incorrect average of version V6"

IMPORTANT: For the sake of transparency, the possibility of comparing these "incorrect" averaged results of version V6 with the other "normal" results of version V7 (both single and averaged) is offered to you: it is thus possible for you to visualize very precisely the difference in results between those of the V7 version which are absolutely perfect (and in particular without any lag!) and those of the V6 version suffering from a slight lag... be careful, however, to only compare results performed exactly in the same conditions (the ideal being to compare an "incorrect average of version V6" with the new average recalculated with version V7 and of course with the same source measurements!) otherwise the comparison will be distorted!

4) Fixed a bug that could occur when disconnecting from the RaceBox Mini & Mini S while it is out of Bluetooth range or discharged

 

First changes in upcoming versions 7.1.X

 

1) Power / Mode 2 only: Addition of a function of power results correction on road slope, with indication of the road slope and the correction applied

However, the use of the RaceBox Mini & Mini S is essential to use this function, the internal GPS of phones being much too inaccurate for an accurate correction!

Moreover, this function (tested for a long time) is NOT a magical function allowing to exempt you from performing measurements in both directions of the road since although it compensates with impressive efficiency for the effects of road slope (with the RaceBox Mini & Mini S), on the other hand it does not compensate for those of the wind (just as important!) AND therefore it remains ESSENTIAL to perform measurements in both directions of the road and average them to obtain perfectly reliable results, thank you for your understanding!

2) Addition of the informative fields "Engine inertia", "Wheels inertia", and "Total inertia" in the car sheets and the power results sheets

3) Improvement of ergonomics (new menu bar at the top or bottom -under consideration-, separation Main measurements / Secondary measurements in the main screen) and aesthetics (addition of logos associated with the types of measurements carried out, implementation of two meters: instantaneous speed, instantaneous power)

 

II) PerfectPower iOS

 

 

Report of version 6.0 released on Sunday May 12, 2024 at 5.33 pm (New York time)

 

Major evolution of the V6 version compared to the V5 version:

1) Ultimate and final optimization of the precision of power and acceleration measurements

A) Return to the signal processing techniques of versions V1 to V4, just deeply reworked and optimized!

Indeed, these techniques have the huge advantage of generating absolutely no lag in the curves, unlike that introduced in the V5 version, which caused a slight permanent delay resulting in an underestimation of maximum torques and a slight delay in maximum power and maximum torque revs...

B) Optimization of the curves smoothing, allowing both to faithfully reproduce the exact behavior of the engine (AND without any lag as explained above!), AND to completely destroy all disturbances (engine vibrations and "road disturbances")

C) Power only: Optimization of the detection of the exact point of end of measurement (rev limiter -on gasoline engine- or foot lift), allowing the addition of the information "Estimated tyre slip"

D) Power only: Conservation and optimization of the system of variable smoothing of the curves depending on the signal / noise ratio (introduced in the V5 version, and allowing an optimal curves precision in all circumstances and the equalization of curves precision in 2nd and in 3rd gear), giving in comparison with the calibration carried out in the V5 version slightly "un-smoothed" curves 

E) Accelerations only: Removal of the system of variable smoothing of the curves depending on the signal / noise ratio (introduced in the V5 version), because it is unsuitable for acceleration measurements in gear change phases ==> Return to the fixed smoothing of versions V1 to V4 but optimized, giving in comparison with the calibration carried out in the V5 version significantly “un-smoothed” and much more realistic curves

2) Power: Addition in the power results sheets of an explanatory text on the "Max speed correction" function ideal in the event of poor GPS reception or failure of this one (indeed, 95% of the measurement accuracy is made by the accelerometer)

 

To be updated...

   

Report of version 5.2

As part of the porting of the V6 Android version to the V5 iOS version:

1) Driving via Bluetooth of the RaceBox Mini (the most efficient external GPS on the market: 25 Hz and 0.3 m average horizontal accuracy!), allowing:

- to further increase the accuracy of PerfectPower measurements (especially the runs flying start)

- the use of the new "GPS only" measurement mode for power & accelerations & braking measurements, which will be added in the version 5.3

2) Addition of 2 warnings to the automated control system for power and acceleration measurements: GPS receiver working, GPS accuracy

 

Report of version 5.3

As part of the porting of the V6 Android version to the V5 iOS version:

1) Addition of braking measurements

2) Addition of the new “GPS only” measurement mode (power & accelerations & braking measurements) allowing the only use of GPS data and therefore allowing to get rid of constraints of the accelerometer, thus allowing:

- to completely free the phone from any mounting requirements (stability, vibration level, positioning)

- to carry out measurements on a road in poor condition, even if this is not recommended from a strict performances point of view, the rolling resistance (and the air resistance to a lesser extent) being seriously increased and variably over time

- to perform power measurements on a rolling start (indeed, the specific calibration phase at standstill is no longer necessary!)

- to no longer have to carry out the difficult specific calibration phase while driving for braking measurements

However, the use of the RaceBox Mini & Mini S is essential to use this mode, the internal GPS of phones still limited to 1 Hz in 2023 being still far too slow!

 

Report of version 5.4

As part of the porting of the V6 Android version to the V5 iOS version:

1) Aesthetic improvements (addition of logos associated with the types of measurements carried out, implementation of two meters: instantaneous speed, instantaneous power)

2) Addition of the function of recalculation of the power results after measurement (very useful in case of incorrect initial configuration of the Setup data and/or the Car sheet)

 

III) Miscellaneous

 

A) Services proposal

 

To all garage managers specializing in Honda based in New York or in the area

 

I offer my help to carry out the mapping of any Honda equipped with a Hondata S300 or K-Pro ECU. I have 5 years of experience in the field in France (2018-2023) where I was entrusted with projects ranging from a 130 hp D16A9 atmo (N/A) to (soon) a K24 Turbo from 800 to 1000 hp, through K20 Turbo from 300 to 500 hp.

 

I just need a full day per car & project to perform an optimal tuning of the engine (performance AND reliability) and all the necessary checks, however it will also be necessary for a mechanic to check all the mechanical and electrical (harness) part of the car before I can carry out the mapping, having enough experience to know that 9 times out of 10 there is a problem at this level (anyway in France).

 

You can contact me by email for any information (Contact section).

 

B) Future developments (PerfectPower Android and iOS 7.X)

 

1) Export data to a CSV file

2) Optimization of the memory management, allowing the import / export of data between phones

3) Optimization of the performances simulation:

- Optimization of the grip limit calculation with modern sport tires (I will lead my own tests with my cars)

- Automatic delivery of reference flying start runs measurements following a power measurement:

25-50 mph & 40-80kph

50-75 mph & 80-120 kph

60-120 mph & 100-200 kph (if the car can of course)

 

C) Projects

 

1) Creation of PerfectPower Motorcycles (adaptation of PerfectPower to motorcycles)

2) Creation of PerfectPower Bicycles (adaptation of PerfectPower to bicycles, with the measurement of instantaneous and average muscular power during a sprint)

3) Creation of PerfectPower Sprinters (adaptation of PerfectPower to sprinters, with the measurement of instantaneous and average muscular power during a sprint)

 

I've had these projects in mind for years, but I would first like to completely finalize PerfectPower before launching them, so they should only see the light of day in 2024.

 

Note: Although the use of the RaceBox Mini will not be essential for PerfectPower Motorcycles (just as it is not for PerfectPower), it will however be essential for the two other projects, thank you for your understanding!

 

IV) Friendly challenge at 10 000 euros & dollars

 

Translation coming soon...

 

En tant que créateur de PerfectPower, j'affirme que:

- PerfectPower V7 est encore plus précise en résultats moteur que n'importe quel banc à rouleaux dans le monde (Maha, Rotronics, DynoJet, etc...)

- PerfectPower V7 est plus précise en résultats moteur que n'importe quelle autre application smartphone (PerfExpert mon ex-application en tête)

 

ET j'offre 10 000 euros & dollars à toute personne qui parviendrait à démontrer que l'une et/ou l'autre de ces deux affirmations n'est pas vraie, mais cela devra se faire dans un cadre strict et professionnel que je définis et qui est le suivant (3 points):

- Une équipe TV (Auto-Moto, Direct Auto, Turbo, etc...) ou Internet ayant une audience mensuelle d'au moins 1 000 000 de personnes devra venir filmer les tests et s'engager à publier les résultats quelqu'ils soient (ce ne sont pas les Youtubers de talent qui font des millions de vues qui manquent je crois...). Cette équipe sera payée après publication des résultats à 50/50 entre la personne relevant mon défi et moi-même, et après acceptation bien sûr par les deux parties de la somme demandée.

- Puisque par définition ni PerfectPower ni aucune autre application smartphone ni aucun banc à rouleaux ne mesure une vraie puissance au moteur mais mesure une puissance en dynamique sur route ou sur des rouleaux et cherche ensuite à "remonter" à la puissance moteur par calcul & estimation des différentes pertes, il sera nécessaire de mesurer un moteur seul au banc moteur et de le monter ensuite dans la voiture pour les tests: ça je peux m'en charger car j'ai les contacts qu'il faut, mais idem cela a un coût et il sera partagé à 50/50 entre la personne relevant mon défi et moi-même. Et inutile de croire qu'il existe dans ce monde un banc à rouleaux ou même un banc à moyeux donnant à tous les coups (pour tous les types de voiture et sur tous les rapports de boite) des résultats moteur 100% justes, ça n'existe PAS comme je 'ai clairement expliqué dans cet article!

- Pour les DEUX affirmations, le comparatif ne portera pas que sur une simple comparaison des résultats moteur de PerfectPower & autre application smartphone & banc à rouleaux avec les résultats moteur de la voiture-test obtenus au banc moteur, mais aussi sur une analyse de la régularité des résultats moteur sur un rapport de boite donné (sur ce point le banc sera grand vainqueur), une comparaison des résultats moteur entre eux sur différents rapports de boite (2-3 sur la route et 2-3-4-5 sur le banc), et enfin une analyse de la forme des courbes. Des notes de 1 à 5 seront attribuées pour chacune des quatre parties et le vainqueur sera naturellement celui qui aura le plus de points sur la totalité des quatre parties.

 

Voilà, ce sont les modalités de base, nul besoin d'en définir d'autres tout est déjà parfaitement clair même si bien sûr (ET si mon défi est relevé...) tout cela sera discuté entre les différents protagonistes et résumé sur papier avant les tests eux-mêmes. ET je tiens à le rappeler, tout ceci est purement AMICAL (et il est même possible que cartaines conditions soient discutées et revues d'un commun accord...), et ce défi a en fait surtout pour objectf de prouver implicitement que PerfectPower est vraiment une application de mesure de puissance et de performances hors-normes et proprement imbattable, même par des matériels de plusieurs dizaines de milliers d'euros & dollars... Pour le relever, il suffit tout simplement de me contacter, mais merci de ne pas me déranger pour rien: si vous n'êtes pas sûr de votre coup (MOI je le suis n'en doutez pas une seconde!), merci d'avance de vous abstenir!
