hard to start after reflash

[andysc3]

I swapped my 4L60E to a 4L80E in my 01 GMC Sierra. I am using COS 0202003. When I do a reflash its hard to get the truck started. It will crank and go to 1000 rpm, then die. It will do this 15-20 times. then when I start it the rpms will go to 2000 for about 5 sec then settle down to the desired idle rpm. can someone look at my tune and help me out. Thanks.4L80.tun

Im looking at it now, just a heads up I get a warning that A0009 Boost VE is out of range. But I dont see any values above 500 so Im confused here...

To clarify, this problem did not exist when you were running the exact same tune just with a 60E trans segment?

Once it actually starts, then the RPMs settle to desired (either 750 or 775 per your tune) and it continues to idle just fine until you flash it again?

The idle section isnt stock, have you done a true hot/cold idle calibration?

Erik, if you view it in g*K/kPa you will see it.

Try setting P0101,2,3 in C6001 to A:1-Trip.

It's didn't happen before. It's a heads cam full bolt on procharged build so pretty much everything has been changed. Joecar, I'll give that a try

Once it starts its fine after that. Until I reflash it with a new tune

What car do you have...?

[andysc3]

Im still having issues with it not wanting to start after a reflash. Is there anything else I can try?

[joecar]

Can you post a log file of it not starting.
