Audi A4 2.7T VEMS Project
The project is a 1996 Audi A4 2.8 with a 2.7T swap.
Using the stock trigger wheel (60-2) and stock sensors for IAT, CLT, with a VW VR6 throttle body, stock turbos. Running with a V3.3 ECU currently running 1.0.36 firmware (I know it's a bit old, but it's pretty stable and I know it should run the 60-2 as I used it on my friends VR6)
We can help upgrading to 1.0.73 or 1.1.26 (or later) if you publish mcd and mct dumpfiles.
For the life of me I can't seem to get the car to run... using the proper settings for a 60-2 in the trigger setup.
- good settings:
- 58 teeth,
- next trigger tooth 20,
- how do you know TDC is 18+65 degrees after the tooth after missing tooth ? Measured with strobe ? Or counted ? Do you have a InputTrigger/TriggerLog ? How do you know trigger polarity ?
- trigger tooth 3
- TDC after the trigger ~65 makes the TDC mark on the crank pulley line up almost perfect.
but trying to start the car, all it does it back fire and kick back. Running 3 two pole coils (from a stock Audi 2.8L V6) directly w/ the VEMS, coil out 0,1 & 2 transversed backwards obviously in MT.
RPM readings are about right I'd say during cranking anywhere from 200-290 RPMs.
Firing order is 1-4-3-6-2-5. Are you certain about the firing order and cylinder numbering ? We had the same symptoms on a V8 when our assumptions on cyl numbers was bad.
The car will somewhat run when the trigger wheel settings are changed to trigger tooth 3 next trigger tooth 10, but the RPMs are WAYYYY off (at approx 2k RPM VEMS is showing 4-45k RPM), but the car runs (we actually drove it out of the shop like that as it had to leave where it was sitting).
I am thoroughly confused about this. Is not every 60-2 wheel set up the same regardless of what car/motor/size of wheel, etc?
MSQ's (obviously for the older MT release for firmware 1.0.36)

- Why don't you use these settings if you know they are proper ?
http://www.vems.hu/files/MembersPage/Sascha/S4/S4_%20fucked.msq - Base map with screwed up trigger wheel settings that actually made the car start/run without too much of a problem (didn't run properly obviously, but was able to drive home)
- with this, did the car start reproducibly without kickback ?
Use the mcd, mct dump format as on IssueReports. Either TerminalProgroma, or with v3gui (available from MegaTune page), File/download-config menu
