Hey guys,
I recently bought another cts-v because i truly love these cars. I'm not very knowledgeable at all but I feel I have come to the right place. I am ordering my HP Tuner this week to hopefully combat these issues I'm having as well. I have attached the HPT file my buddy saved from viewing it with his, and also am attaching the list of mods that were advertised with the car. The car has been having issues where the AFR states 16-20:1 at idle, at first it will be at 14:1 then slowly lean out max 20:1 but constantly fluctuating. When i barely touch the accelerator it kind of burbles and misses, and drops idle and when i let out it sometimes stalls, also occurring in drive-thrus and backing out of my driveway, from what I've researched I cant see why the stoich AFR was set to 29 by previous tuner. I am not smart enough to know why that ever may be necessary. On my Autel scanner its logging around -10 ST fuel trims at idle. Could you look at the tune and possibly tell me what's funky? It seems like there were many edits but I couldn't make sense of anything. Much appreciated.
