effxr6t Posted March 23, 2020 Share Posted March 23, 2020 Having a few issues with closed loop fueling even when ive disabled as described in the HOW TO which didnt work. This ecu doesn't have any o2 sensors wired to the pcm so it should allready run in open loop as they are basically the same as disconnecting the plug in the car So to start i maxxed auF2504 to 36000s and auF0163 to 4096* but upon starting it still would start maxxing the trims out flooding it with fuel. After this didnt work i went back and set the closed loop delay to 36000 seconds which stopped it mostly but even after ~5mins it goes back into closed loop and again starts adding fuel. Ive also lowered the tps transition to try stop it but that did nothing. If anyone has encountered this issue and has any solutions or ways to actually disable closed loop so it will run open loop 24/7. Its on a drift car and having to restart the car every 5 mins trying to tune it or driving it around the track is f@#%ed Cheers for any help Quote Link to comment Share on other sites More sharing options...
