Title: Adjusting TVUB Post by: seanf on April 24, 2021, 06:29:29 PM After playing around raising and lowering trying to fine tune my idle I need to increase TVUB to richen it up at idle? Or lower? I could not find a clear answer searching. In my mind I would want to increase voltage offset to richen it up, It seems no matter which way I change it its still lean at idle according to my wideband and on hot idle I get missfires. I'm trying to dial it in with injector offset before I start playing too much with idle torque reserve.
