Thought I would start a thread here. I bought a MS3 with 3X from Need_A_VR6 and he has been a great help, looking to get some more advice here to get this car going good so I am not always nagging Paul!
93 Corrado VR6 with 3.0L, big valve, cams, Precision HP6262BB, 60# injectors.
SRI with a MK3 ODB2 throttle body. 3" exhaust, kinetic manifold. Not sure what else is important!
I cut out the factory ecu and wired in the MS3 using the MS3X for the injectors and ignition, using factory coil pack. Injection is set to batch currently.
So with Pauls help, I got the car to idle. It would start and then stall. I calculated the required fuel at 5.3 but I kept upping it until I could get it to start and stay running. I ended up at 22! and it would idle at 2200rpm.
I think the problem has to do with the odb2 throttle body, when the MS turns on it opens up the throttle body, possibly too much? Is this normal? as per Pauls instructions, I set it to 195hz.
This is the point I am currently stuck at. I have a wideband but not wired in yet, I am about to do that tonight.
