Engine: 3.2 24S (L6) (S54B32)

Manufacturer data: 338 hp @ 7900 rpm - 269 lb.ft @ 4900 rpm

ECU: Siemens MSS 54 HP (original of BMW M3 E46 CSL)

Mapping (David & Vincent): Optimized this day by David and Vincent (PerfectPower group)

Fuel: UL 98

2) PerfectPower weighing

Date: Sa 06052023

Location: France - 45

Note 1: Weighing with 7/8 of the tank

Note 2: 1560 kg = 3439 lb

3) PerfectPower sheet

4) PerfectPower results (Power)

Date: Sa 06052023

Location: France - 45

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 (3/4 at the end!)

- With rear tires 265/30R19

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

- 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)

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

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...

A) Final map

Comparison of the two measurements

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)

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.

2) PerfectPower results (Lap Timer)

1) Car

Car: Audi S2 6-speed (1993) - David

Engine: 2.2 20V turbo (L5) (ABY)

Manufacturer data: 227 hp @ 5900 rpm - 258 lb.ft @ 1900 rpm

ECU: Bosch Motronic 2.3 (original)

Mapping: Original (just boost control disabled, N75 removed, and lambda sensor unplugged)

Mechanical setup: Intake (RS2 airbox) - Exhaust (RS2 downpipe + custom decata stainless steel line 2X60 then 1x80 instead of 2x50 then 1x60) - Wagner RS2 Evo 2 intercooler - Siemens Deka IV 480 cm3/min injectors - AEM 340 L/h fuel pump for E85 - RS2 flowmeter - S3 dump valve - Turbo valve opened 1 turn (= 1.0 bar) at this session ==> Normal Boost setting

Fuel: E85 (E75 checked in reality!)

Power measured with PerfectPower: 277 hp

Chassis setup: KW V3 Springs & Shock absorbers Kit - "Big front brakes" Kit (HISPEC discs + calipers, MINTEX pads) (but rear original) - Nankang NS2R 225/45R17 semi-slick tires

Note 1: I prepared my Audi S2 for the track over the 2020-2022 period, so it has nothing original left apart from the engine / turbo / gearbox / axle assembly still 100% original ( and... more than 280,000 km!).

Note 2: The turbo pressure was set to its normal value for track use at this session (1.0 bar). For information, the original turbo pressure is 0.8 bar.

Note 3: Without going into somewhat complex technical details, great care has been taken to find a mixture richness (AFR) at full load as close as possible to that in the 100% original mechanical configuration, in order not only to maintain an excellent mechanical reliability of course, but also to obtain results as representative as possible of this engine in this prepared mechanical configuration and with E85, but at 1.0 bar of turbo pressure AND with injection and ignition settings 100% original!

2) PerfectPower results (Lap Timer)

Date: Su 27112022

Location: France - 03 (Lurcy-Levis track)

Software: PerfectPower Androïd 6.0 Test (new version)

Hardware: Xiaomi MI 8 + SkyPro XGPS 160 10 Hz communicating via Bluetooth with PerfectPower

Report:

- Taking of landmarks (GPS coordinates) of the reference point of the Lurcy-Levis track for the PerfectPower Lap Timer

- Validation tests of the PerfectPower Lap Timer in parallel with the Alfano of my colleague Edouard

- Establishment of a reference time for the first track outing of my Audi S2 in its current configuration

Note: Cloudy weather all day, wet track in the morning but very dry in the afternoon

1) Taking in the morning of the GPS coordinates of a reference point (end of straight line, first braking cone) of this Lurcy-Levis track for the PerfectPower Lap Timer, as a passenger in a Honda Civic ED7 1.6 16V. These GPS coordinates have then been manually entered into the PerfectPower Lap Timer for the rest of this track day, but of course I then created in this Android 6.0 version a track selection system containing the GPS coordinates of the reference point of the tracks recorded and therefore allowing the user to not having to enter them manually.

2) Validation tests of the PerfectPower Lap Timer in parallel with the Alfano of my colleague Edouard, over a full session of around ten chrono laps in the middle of the afternoon

REPORT: All the lap times are extremely close, less than a tenth of a second on average... BUT advantage to the PerfectPower Lap Timer all the same which recorded ALL of the laps performed, unlike the Alfano which skipped some! This is due to an imperfect programming of the passage detection of the car at the chosen reference point, which must be done according to the smartest strategy possible...

3) Establishment of a reference time for the first track outing of my Audi S2 in its current configuration, over the last session of the day (5 chrono laps, slow-down on the last): 1'23"3 (109.77 km/h average)

PerfectPower App Privacy Policy

- Application developer: David METTEY

- Person to contact on privacy issues: David METTEY, by email via the application (SETUP page, Contact button)

- The one and only sensitive and personal user data accessed by the PerfectPower application is the GPS position, and it uses this data ONLY to perform the functions for which it was developed: the measurement of the standardized engine power, the accelerations standing and flying start, the braking, and the maximum speed of your car, the calculation of the gearbox ratios of this one by rev calibration, the measurement of the losses of this one in free-wheeling, the simulation of the performances of this one (indirectly after a power measurement), and finally the measurement of your lap times on track.

Moreover, it does not collect or share with anyone or anything the various GPS positions taken when it is active, and it instantly stops taking them when it is in the background.

And finally, it NEVER saves them in the permanent memory of the phone.

- These GPS positions however are not encrypted in the application, but this is not a privacy issue since as said above these data are used only for calculation purposes AND only when the application is active, and they are NEVER stored in the permanent memory of the phone.

- These GPS positions therefore transit ONLY in the RAM of the phone and ONLY while the application is active, they are NEVER in the permanent memory of the phone, and they are instantly deleted from this RAM as soon as the application is in the background or of course closed.

4) PerfectPower results

Date: Fr 16122022

Location: France - 45

Note: Measurements performed:

- With 2 people on board (Edouard & David) and with full tank

- With 190/580 competition slick tires (equivalent in road dimensions: 190/52R15)

- In 5th gear from 2000 to 8100 rpm (rev limiter), since at this power level (415 hp), it was impossible for us to measure it either in 2 or in 3 or even in 4 due to insufficient grip!

- 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 our case we have a perfectly flat measurement track and that no wind was blowing that day

- With the assistance of a 10 Hz external GPS (SkyPro XGPS160) communicating in bluetooth with PerfectPower and the use of the WIXGEAR universal magnetic windshield mount according to the strict recommandation of PerfectPower for the most accurate measurements possible
