Ecumaster forum

I've been working on this 3000gt vr4, and I'm having some strange issues with the DET3 unit. Lets say I'm revving the car up, AFR's are in the ten's. I'll go to that cell and remove fuel, and it'll be 13-15's AFR. However, if I hit the same cells again, it'll go massively lean, or massively rich the second or third time. I thought maybe a bad ECU, but I've swapped in another unit, and it does virtually the same thing.

Post up a log and the configuration/map, that will help narrow it down.

Here is the log and setup file. For some reason I couldn't get attach it to the forum. It doesn't seem to allow the .dlg, and .pbp extensions.


Here is some idling and a little revving. It's all partial throttle.
