Random Ramp up in Rpm?
Hello,
I have attached a datalog of what is happening as well as my tune if necessary. Just trying to get some help as to what is going on someone confirm my suspicions. What is happening is the rpm will shoot up, there will be a slight increase and then finally it will enter closed loop and Idle VE and drop to normal AFR and my idle rpm. Thought this could be wrong Initial Idle values but that doesn't seem right the more I think about it. Seems it is just not entering closed loop and therefore Idle VE as I would like. Is this what it seems like, or am I missing something completely. I had changed a lot of things recently when receiving help from others which has been overall successful, just trying to now troubleshoot this one thing so I can further tune Closed Loop Idle PID. The data log is from a couple instances of this happening in second gear of me making it occur, It happens in all gears as let the throttle all the way out. Sound like RPM dot? Thanks!
