With this colder weather hitting us, my cold start is causing stalls. I start the engine and about 60% of the time, the car will just stall out completely. I have an older tune which starts my car fine. How hard would it be to swap the start up parameters from my old tune to my new one? I contacted my tuner but haven't gotten a response. Which columns which I have to swap as well? Thanks in advance. The car runs like a champ when its normal operating range, just this issue when it's completely cold. Ecuflash,ecuboost, and sd.

 

It's really a blind guess not knowing what has been tuned, and not knowing why your car won't start with the new tune. Basically try swapping all idle and ISCV tables. It's a good start. And maybe some fuel category maps like all the cranking enrichment, post primer enrichment.

 

Thanks, it sounds like I better wait for my tuner to get back to me on this issue then. That's above my level on tuning
