[QUOTE="96dreamer, post: 16491229, member: 52560"] Took the car to the track for the first time last night and am having issues with it running leaner in lower gears off the launch. It leaned out so much in 2nd it tripped the AFR safety and shut the car down. After it hit the reset parameters I continued the pass in 2nd -5th with AFR's holding pretty close to the target getting slightly richer with each shift. Not sure what I should be looking for that would cause this. Tank was around 1/2 for all passes so I don't think fuel slosh was an issue. Screenshot of the data log below. AFR safety tripped where the tracer line is. [ATTACH=full]1662986[/ATTACH] Log from just after afr safety rest finishing the pull and having great afrs. [ATTACH=full]1662987[/ATTACH] Car is running a ms3pro ultimate, novi 2000, wastegate for boost control and fuel on these passes was around e60. I cut down e85 with 93 to try and get a bit more volume out of the pump since I was running out of full on straight e85. [/QUOTE]
