If your car is eating ECU's .. CHECK ALL EARTH CONNECTIONS ASAP. any bad earth can have a starter motor seek GND to Battery through anything electrically connected. Engine to body, Body to battery, ECU/Engine Wiring Loom Earthed to same point as Body/Battery earth. remove them, grind them,make the bolts shine, use proper earthing (sharp annoying star type) washers.kaptainkool wrote:It does indeed appear to be jumping to the knock maps. I don't have the logs on hand but it doesn't get as rich now. Thanks for cleaning up the fuel maps they were pretty bad. Unfortunately a whole other problem as re-developed again and its left me completely demoralized. My car is eating ECU's it seems like. My last nistune'd ecu worked well for a month or so until it developed an inconsistent A/F under low load. It eventually lost it's ability to maintain idle (was idling really high). The whole time nistune wasn't showing anything to explain these behaviors. I've replaced the TPS/TVS (re-calibrated), the temp sensor, and the MAF (another stock, then the N62) no change. I then replaced the ECU and all the problems went away (same nistune module, same tune). I ditched the tune and went with this current Frankenstein one. Very recently my ecu stopped cold enriching on cold starts and now warm/cold idles at either 14:1 or 16-17:1. I must be missing something stupid but I really can't figure it out.
