I'm currently using VEMS on my daily driver Audi RS2 with 16x14 maps.
Just tested 1.1.9 firmware with auditrigger:
- Gets cam sync much faster when cranking than older version, very nice!
- When revving engine without load (neutral) gives trigger error around 6500 rpm
- When revving engine with load (2nd gear) gives trigger error around 4000 rpm
- after trigger error ignition stays off until revs are below 2000.
- base timing seems to be quite a bit different than with earlier firmware

Here is a dump and log from 1.1.9
Today it felt better than last time I tried it. Unfortunately I didn't have timing lamp available so I couldn't check base timing. Plenty of trouble due to lack of proper vemsv3.ini for this config and tables.

Yesterday I had plenty of trouble starting the engine when temp around -15°C.
Engine crank about nice, took bit of a while to get cam sync (1.0.53).
After getting sync engine tries to start (promises) but fails to start. Problem is that there seems to be a strange gap in ignition(?) when mode is changed from crank to running. Some inertia is needed to get over it and with a cold engine it is a real problem.
I tried different crank and afterstart ignition and fueling settings, no luck.
Another problem is that ecu seems to do too much Air Den enrichment. If I tune fuel-Map when IAT is around 10°C, it has to be changed to leaner about 5% when IAT is below 0°C, and even more when IAT is -10°C. (With warm engine of course)
