My daily driver, Audi S6 avant -95, 2.3L inline 5, 20 valve turbocharged engine (AAN).
Going to install VEMS as direct replacement of original ECU (see PlugAndPlayMotronic) using factory wiring. Extra wires are needed only for WBO2.
Megatune settings (06-Jan-2006):
My config.txt and tables.txt:
Flying wire adaptor for basic functionality from genboard (v3.3) towards motronic connector (pins Mxx)
- 5x high-Z injectors (INJA..E to M36,M17,M34,M35,M16, INJA = cyl #1 and so on)
- 5x ignition coils (with power output stages) (IGN00..04 to M01, M02, M23, M20, M21, IGN00 = cyl#1 and so on)
- so h[2]=03 01 00 02 04 ... required to match 53124 fire order as requested on InputTrigger/AudiTrigger !!!
- BoostControl solenoid aka WGFV (INJG to M33)
- Idle air controller (INJH to M04)
- Fuelpump relay (P259/5 to M03)
- 3x trigger signals, 2x VR (M47 home signal, M49 rpm, M48 GND) + 1x hall (M08), InputTrigger/AudiTrigger setup
- GND and Supply voltages
- to board itself with additional relay
- 5V to hall, TPS (EC36/28 to M12)
- TPS sensor (M53)
- CLT (M45), IAT (M44) sensors
- Tachometer (M40)
- Knock sensor
Will add wiring diagram later..
Hardware changes made to V3.3 board
- Trigger related
- R182 shorted (instead of 100k in primary trigger)
- 10k pullup to 5V for secondary VR signal
- All ign channels changed to logic level
Config notes
- injpwm=FF # highZ injectors
- req_fuel=50 # is that for max VE = appr 200 ?
- cwl=5A # might be close
- cwh=19 # maybe a bit high but you'll see when it warms up :-)
- primep=26 # give it a little (3.8msec) in cold
- primep_temp_scaling=00 # but not with hot clt
- awev=0D # try to increase, upto 40 (+64%), especially when warmup and other tables are unknown yet
- awev_temp_scaling=80
- ...
ouch, why are we guessing? A similar engine is running:
MembersPage/NanassyPeter/Config so use Peter's config. just update
- injector (primarily cwl, cwh, req_fuel and injpwm)
- trigger config (you know that already, according to InputTrigger/AudiTrigger )
My car is a s2 coupe turbo quattro but only distributor based.
I use all factory sensors and valves through a flying cable set.
Can you send to me your recent msq.file.Thanks!
