Summary of change:
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. http://www.audiclub.fi/kalske/vems/119/ ----- 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. '''A:''' You have a Very High ignition advance from low RPM, (30+ degrees), also a very low cranking threshold rpm (300) and a low cranking advance Set all three leftmost bins in the whole spark table to 15,9,25 and set a 15 degree cranking advance, 400 rpm threshold and try again //Emil '''Result:''' No difference 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) Log, dump and msq can be found here: http://www.audiclub.fi/kalske/vems/ --------- 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 --------- Additional info to my 55pin v3.3 order * all with MAP connection 400kPa onboard (6/4mm pneumatic) * PowerFlyback with 30V diode * 27k pullup and 2,7k pulldown * LCD-connector (no PS2 connector) * WBO2 connection with 5pin EC male * Knock and EGT yes * bias support to audi std PTC IATs - 3pc for AAN/ADU/ABY - 3pc for 3B * with 5pin EC female for COP upgrade
