Teppo Kalske from Finland, born 1972

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)

I need help for picking right sensor-files, these are the measured points:

CLT (audi 5cyl 20vt standard sensor):

-20°C 11000 Ohm

0°C 6000 Ohm

100°C 200 Ohm

IAT (audi 1.8T 20v sensor):

-40°C 80000 Ohm

20°C 2400 Ohm

130°C 100 Ohm
