Date: Fri 02022024

Location: France - 45

 

Car configuration: Optimization of the mapping by David and Vincent (PerfectPower group)

 

Software: PerfectPower Androïd 6.1.7 (new version)

Hardware: Xiaomi MI 8 + RaceBox Mini 25 Hz driven by PerfectPower

 

Report: Two measurements performed for the validation of the results of each map tested:

- With 3 people on board (Abdel & Vincent & David) and with 3/8 of the tank (24 L)

- In 3rd gear from 2000 to 8200 rpm (rev limiter)

- With the use of the WIXGEAR universal magnetic windshield mount according to the strict recommendation of PerfectPower for the most accurate measurements possible

- In both directions of the road then averaging of these two measurements according to the strict recommendation of PerfectPower in order to eliminate the effects of road slope and wind (road used on a false flat, 5 to 9 hp difference between the two directions) 

  

A) Final Map V7

  

Official Result = Average of the two measurements

 

 

B) Comparison BEFORE (Map V4) / AFTER (Final Map V7)

 

Official results of each map

 

Note 1: Map V4 is not a starting map, it is a map already optimized on the injection settings! Vincent and I who have years of experience on these engines (we have adjusted dozens of them) do not need to carry out PerfectPower measurements to optimize injection, so we only start them afterwards.

 

Note 2: The total gain obtained from the optimization of the ignition advance is 9 hp (from 335 to 344), and we estimate that obtained from the optimization of the injection (not measured) at around 5 hp, i.e. a total injection + ignition gain of around fifteen hp.

     1) Power - 13102023 (190 hp & NewBase Map)

 

I) Car

 

Car: Honda CRX 1.6i-16 ED9 (1992) with compressor - David

Engine: 1.6 16V (L4) (D16A9) + compressor Jackson Racing

Manufacturer data: 128 hp @ 6800 rpm - 105 lb.ft @ 5700 rpm

ECU: Hondata S300 V3 (programmable)

Mapping (David): NewBase Map (new base to redo an optimal development on this car that I had tuned in 2020 and that I repurchased in 2023)

Mechanical setup: Compressor conversion with numerous adaptations

Fuel: E85

 

Chassis setup: Track preparation - Toyo R888R 205/50R15 semi-slick tires

 

Note: As mentioned in the description above, this car is prepared for the track, and it also has a compressor and Hondata S300 V3 programmable management. I bought it on Saturday September 16, 2023, and it is the new PerfectPower showcase! Edouard and I are just going to review and optimize the compressor conversion and track preparation in 2024 to make it a formidable machine!

1) Power - 13102023

 

Date: Fri 13102023

Location: France - 45 (PerfectPower test track)

 

Car configuration: NewBase Map (= Max Map of Sat 29042023 restricted: ignition advances reduced, rev limiter lowered by 200 rpm -6800 rpm instead of 7000-)

 

Software: PerfectPower Androïd 6.1.5 (new version)

Hardware: Xiaomi MI 8 + RaceBox Mini 25 Hz driven by PerfectPower

 

Report: Two measurements performed for the validation of the results of the NewBase map:

- With 1 people on board (David) and with full tank (45 L)

- In 3rd gear from 2000 to 6800 rpm (rev limiter)

- With the use of the WIXGEAR universal magnetic windshield mount according to the strict recommendation of PerfectPower for the most accurate measurements possible

- In both directions of the road then averaging of these two measurements according to the strict recommendation of PerfectPower in order to eliminate the effects of road slope and wind, and this even if in my case I have a perfectly flat measurement track and that no wind was blowing that day

 

Note 1: The objective of this NewBase map is in no way to produce maximum results, but only to create a new base to redo an optimal development on this car that I had tuned in 2020 (development of the Max map) and which was measured on the JS Performance dyno (France) on Sat 29042023 with this Max map at 205 ch (202 hp) and 228 Nm (168 lb.ft) (photo below). However, as said at the beginning of the article, Edouard and I are going to review and optimize the compressor conversion during 2024 with the objective of course of exceeding these 205 ch (202 hp) and 228 Nm (168 lb.ft)!

 

 

Note 2: The E85 used for this session was E70 verified in reality!

 

 

Comparison of the two measurements

 

 

Official Result = Average of the two measurements

 

 

Note 1: With 190 hp and 164 lb.ft rounded, the NewBase map is therefore 12 hp and 4 lb.ft from the results obtained on the dyno on Sat 29042023 with the Max map (202 hp and 168 lb.ft rounded), which is superbly consistent with the restriction carried out, more penalizing for the max power than the max torque with the rev limiter lowered by 200 rpm (from 7000 to 6800) on an engine where the max power is still skyrocketing at the moment of the rev limiter!

 

Note 2: The rev limiter includes a pre-limit with a progressive reduction in ignition advances to protect the engine as it approaches the rev limiter, although this is hardly visible on the curves as the power is still in full ascending phase at this moment!

 

Note 3: To be honest, I had planned to make a video for the power measurements as I had done with my Audi S2, but in the current state of the chassis settings of this CRX, it was simply unthinkable to do not hold the steering wheel with both hands during power measurements!!! And yet I'm not cold in my eyes (French expression), I can slide the back of my S2 at 180 km/h (112 mph) chrono and play with it as I want, but for the moment this CRX needs adjustments, and this is why Edouard and I are going to seriously work on it during 2024!

Car configuration: Optimization of the mapping by David and Vincent (PerfectPower group)

 

Software: PerfectPower Androïd 6.1.5 (new version)

Hardware: Xiaomi MI 8 + RaceBox Mini 25 Hz driven by PerfectPower

 

Report: Two measurements performed for the validation of the results of each map tested (sometimes 4 in case of doubt due to random wind):

- With 3 people on board (Stephane & Vincent & David) and with half of the tank (31.5 L)

- In 2nd gear from 2000 to 8200 rpm (rev limiter)

- With the use of the WIXGEAR universal magnetic windshield mount according to the strict recommendation of PerfectPower for the most accurate measurements possible

- In both directions of the road then averaging of these two measurements according to the strict recommendation of PerfectPower in order to eliminate the effects of road slope and wind (road used almost flat, 2 hp difference between the two directions... when the wind was not blowing!)

  

A) Final Map V7

  

Official Result = Average of the two measurements

 

 

Note: Vincent and I would like to emphasize the excellent results of this M3 E46 only equipped with a Venturi effect airbox that we had never tested and of which we therefore do not know the gain (the injectors and the pump are mainly an adaptation necessary for the ethanol conversion), and having an engine totaling... 260,000 km (admittedly redone at 180,000 km)! Knowing that the very best BMW M3 E46s come out around 335 hp 100% original and that the average is rather around 325, we can conclude as I said with humor (AND caricature!) to Stephane its owner that or it has an exceptional engine and the airbox brings nothing, or it has a standard engine and the airbox brings a phenomenal gain!

 

B) Comparison BEFORE (Map V4) / AFTER (Final Map V7)

 

Official results of each map

 

 

Note 1: This comparison actually shows the results of three states and not two:

Map V4 (white curves) = Map with optimized injection

Map V7 (red curves) = Map with optimized injection and ignition

Final Map V7 (green curves) = Map V7 (red curves) slightly restricted on ignition advances for engine protection (260,000 km AND track use !!!)

 

Note 2: As mentioned in note 1, Map V4 is not a starting map, it is a map already optimized on the injection settings! Vincent and I who have years of experience on these engines (we have adjusted dozens of them) do not need to carry out PerfectPower measurements to optimize injection, so we only start them afterwards.

1) Power - 03112023

 

Date: Fri 03112023

Location: France - 45 (PerfectPower test track)

 

Car configuration: Optimization of the mapping by David and Vincent (PerfectPower group)

 

Software: PerfectPower Androïd 6.1.5 (new version)

Hardware: Xiaomi MI 8 + RaceBox Mini 25 Hz driven by PerfectPower / Samsung Galaxy A10 + RaceBox Mini 25 Hz driven by PerfectPower

 

Report: Two measurements performed for the validation of the results of each map tested:

- With 3 people on board (Olivier & Vincent & David) and with three quarters of the tank (47 L)

- In 3rd gear from 2500 to 8600 rpm (rev limiter)

- With the use of the WIXGEAR universal magnetic windshield mount according to the strict recommendation of PerfectPower for the most accurate measurements possible

- In both directions of the road then averaging of these two measurements according to the strict recommendation of PerfectPower in order to eliminate the effects of road slope and wind

 

Note 1: This is a complete development (VANOS intake + exhaust, injection, ignition) with E85 which has been performed on this BMW M3 E92 which was the first that Vincent and I did, with at the end exceptional results!

 

Note 2: We used two phones (my Xiaomi MI 8 and Olivier's Samsung Galaxy A10) each driving their own RaceBox Mini, and we carried out all the measurements simultaneously with the two phones and validated the results of each tested map with the Xiaomi MI 8 of exceptional accelerometer quality (results always perfectly stable).

 

Note 3: The E85 used for this session was E80 verified in reality!

 

 

A) Final Map V17

 

Official Result = Average of the two measurements with the Xiaomi MI 8

 

450.1 ch = 443.9 hp & 408.2 Nm = 301.1 lb.ft

 

Note: We had a target of 450 metric hp (444 imperial hp)... AND we barely reached them! FYI, such a value is exceptional for this engine!

B) Comparison Original Map (424 ch) / Optimized Map (440 ch) with UL 98

 

Unofficial results of each map with the Samsung Galaxy A10

 

 

Note: This comparison presents results of measurements carried out with UL 98 and long before this current adjustment session on Friday November 3, 2023 with E85! It was Olivier himself who carried out these measurements AND this development with UL 98 over several days after I explained to him exactly how to do it and he followed my instructions to the letter and the result was that he accomplished exceptional work and much better than that of many installed professionals!

Of course, we redid a complete development Vincent and I for the optimization of the mapping with E85 and we carried out specific tasks that Olivier was not able to carry out alone such as the ethanol conversion itself (taking into account the new injectors, adjustment of cold start injection, etc.) and the addition of a switch-map function to switch from the E85 map to the UL 98 map and vice versa, and of course we are happy to have succeeded in reaching our (difficult!) objective of 450 metric hp!

 

C) Comparison Optimized Map with UL 98 (440 ch) / with E85 (unofficial 453 ch)

 

Unofficial results of each map with the Samsung Galaxy A10

 

 

Note: As explained before, we noted in our measurements in parallel with the two phones a perfect stability of the results and the accuracy of the curves at all points with the Xiaomi MI 8, when it happened that measurements had abnormal variations (especially at high revs) with the Samsung Galaxy A10, and the only reason for this is the difference in accelerometer quality between the two phones since the GPS information came in both cases from a RaceBox Mini, and this is why we can ONLY make official the results obtained with the Xiaomi MI 8, i.e. 450 metric hp with the optimized map with E85 (final map V17), and not the 453 metric hp measured with the Samsung Galaxy A10.

 

2) Power - 28012024

 

Date: Sun 28012024

Location: France - 45 (PerfectPower test track)

 

Car configuration: Same map optimized for E85 (final map V17)

 

Software: PerfectPower Androïd 6.1.7 (new version)

Hardware: Samsung Galaxy S23 (new Olivier's phone) + RaceBox Mini 25 Hz driven by PerfectPower

 

Report: Two measurements performed:

- With 1 people on board (Olivier) and with full tank (63 L)

- In 3rd gear from 2500 to 8600 rpm (rev limiter)

- With the use of an excellent windshield mount according to the strict recommendation of PerfectPower for the most accurate measurements possible

- In both directions of the road then averaging of these two measurements according to the strict recommendation of PerfectPower in order to eliminate the effects of road slope and wind

 

Note 1: The aim of the game of this session was simply to confirm several months later and with winter ethanol (E70 verified) the 450 ch (444 hp) recorded on November 3, 2023 with the final map V17!

 

Note 2: Olivier was able to release his new phone with these measurements, a Samsung Galaxy S23, with much better accelerometer quality than that of his old Samsung Galaxy A10! By the way, the results obtained are extremely close to those obtained with my Xiaomi MI 8 on November 3, 2023, with only 0.9 ch & hp difference (451 vs 450.1), when we had 2.6 with his old Samsung Galaxy A10 (452.7 vs 450.1)!

 

Note 3: The E85 used for this session was E70 verified in reality!

 

 

Official Result = Average of the two measurements

 

451.0 ch = 444.8 hp & 412.8 Nm = 304.5 lb.ft

 

Note: As said, the 450 ch (444 hp) are well confirmed with this final map V17 (and not the V18 of the screen, it is an Olivier's mistake), and this both with summer ethanol (E80 from November 3, 2023) and with winter ethanol (E70 from January 28, 2024)!

Car configuration: Optimization of the mapping by David and Vincent (PerfectPower group)

 

Software: PerfectPower Androïd 6.1.2 (new version)

Hardware: Xiaomi MI 8 + RaceBox Mini 25 Hz driven by PerfectPower

 

Report: Two measurements performed for the validation of the results of each map tested:

- With 3 people on board (Laurent & Vincent & David) and with 7/8 of the tank (55 L)

- In 2nd gear from 2000 to 8200 rpm (rev limiter)

- With the use of the WIXGEAR universal magnetic windshield mount according to the strict recommendation of PerfectPower for the most accurate measurements possible

- In both directions of the road then averaging of these two measurements according to the strict recommendation of PerfectPower in order to eliminate the effects of road slope and wind (road used in false flat, 8 to 10 hp difference between the two directions)

 

Note: This tuning session was the 1st carried out with the RaceBox Mini (after years with the already excellent SkyPro XGPS 160), and all the measurements carried out were of an absolutely flawless accuracy (even including on one measurement the detection of a drop of 5 hp between 7300 and 8200 rpm due to a knocking detection on two cylinders generating a sharp drop in ignition advance on these two cylinders which should result in a calculated overall power drop of... 5 hp!), allowing the optimal tuning of this M3 E46 in a record time, even shorter than this we would have taken on dyno if we take into account the (significant!) time of complete installation of the car on the dyno (centering, strapping, rev calibration, eventual calibration of the brake level, etc...): very frankly, with the sole exception of the particular case of extreme cars that can not be driven on road, using a chassis dynamometer in 2023 or later when you can use the PerfectPower + RaceBox couple being even more efficient and incomparably cheaper is no longer justified, whether for a simple power & torque measurement or for a complete adjustment, and it is obvious that all true enthusiasts and connoisseurs will understand this perfectly...

Official Result = Average of the two measurements

 

 

Note: The whole tuning session was done with the air conditioning on, but unfortunately we didn't think of doing two new final measurements with the air conditioning off to see if that changed the results or not! Indeed, on some cars, the air conditioning compressor is disengaged in full load, and on others not... BUT Vincent and I will do this test as soon as the next M3 E46 is tuned, and we will give the results here!

 

B) Comparison BEFORE (Map 1) / AFTER (Final map)

 

Official results of each map

 

Note: Map 1 is not a starting map, it is a map already optimized on the injection settings! Vincent and I who have years of experience on these engines (we have adjusted dozens of them) do not need to carry out PerfectPower measurements to optimize injection, so we only start them afterwards.
