autoaddictions

Im having a strange issue i have a s10 with a ls1 swap running 4l80e.Its a 3 bar speed density tune! For some reason i cant get the engine to start for several hours after i make a change in the tune. if i crank it for hours it will start or it sits for half a day firs right up. I have the engine running good but im having some wot shifting issues. Every time i edit the tune to make shift point changes and reflash the truck wont start for hours. It appears that it wont start until the mass air flow fail sets the code. After that it will start every time.
any one seen this before.I will post my tune if somebody thinks they can help.

You need to set the MAF DTC's to trigger immediately.
