I'm not new to EFI in general but am relatively new to VEMS. I've just recently started playing with a plug and play motronic VEMS unit.
My current fleet:
1995 Audi S6:
stock 5 cylinder AAN motor
034 EFI Stage IIC standalone system running on 60-2 wheel, waste spark
GT3071 turbo, custom downpipe and exhaust
FMIC
60lb/hr fuel injectors
044 "motorsports" fuel pump
1990 Audi Coupe Quattro:
3.6L v8 twin turbo (PT code motor from V8 quattro)
034 EFI Stage IIC (actually the same computer as the above car.. good thing I cant drive both cars at once because I only have one ECU!)
dual T3 60 series turbos (.6 A/R)
dual intercoolers
big-a$$ double row aluminum radiator
crank mounted 60-2 wheel, running waste spark
coil on plug
dual path exhaust (side exit and rear exit, boost actuated side valve)
My plan is to install a PNP motronic VEMS unit on the S6 and keep 034 on the v8 mostly so I can stop swapping the ECU around but also to learn the ins and outs of VEMS.
More VEMS related stuff coming soon!
PNP box is in my S6 now. Some suggested idle settings by Jorgen that I need to try:
(10:00:06 AM) Jorgen1_: enabled
(10:00:09 AM) Jorgen1_: 20
(10:00:13 AM) Jorgen1_: 0
(10:00:15 AM) Jorgen1_: 20
(10:00:16 AM) Jorgen1_: 2
(10:00:19 AM) Jorgen1_: Enabled
(10:00:23 AM) Jorgen1_: 20
(10:00:24 AM) Jorgen1_: 10
(10:00:25 AM) Jorgen1_: 50
(10:00:26 AM) Jorgen1_: 10
(10:00:28 AM) Jorgen1_: 55
(10:00:29 AM) Jorgen1_: 20
(10:00:30 AM) Jorgen1_: 10
(10:00:34 AM) Jorgen1_: 128
More of a note for myself, CEL wired as follows, awaiting firmware support to be useful though:
AANpin22 = EC36pin15 = p259/5
Having some triggering problems with cars with 7A flywheels. I've got a trigger log from a good running S6:

and a trigger log from a car that generates trigger errors running a 7a flywheel (which works fine with motronic):

can any trigger log experts spot the problem?
