I can tell you it is the tune. My car does the same thing when it is cold out. Once it warms up, the car starts and like normal. I just had the plugs/wires replaced last year (about 5k on them). You also have to note that I have a Hydra tune and no MAF for cooler weather.....
Oh right, I keep forgetting that yours is turbo'd w/ aftermarket electrics on it. Yeah, the startup and warm-up enrichments are definitely boofed. What ECU is it?
Bolded for the key phrase. The MS3 and MS6 motors are reaaallllllyyyyyy finicky and touchy to mods. You do know I have a MS6 and their motors are identical, right?
yeah, I don't know what mods you've got on it though. I had every single CP-E mod available except the flash, plus a DNP mani with external waste gate. Fez has that and a bigger turbo with the stock wastegate plus a tune, it hasn't blown up but he can't drive it, can't figure out what's wrong with it. I know the BP engine is very strong so that keeps me thinking, I've thought about the BEGi flash instead of the Hydra but I want a roll cage and moar seat time before I add moar powar
