No need, it's just a repository file renamed with useful info instead of random numbers.
Hey thanks man, greatly appreciate you
The attachment appears dead - any way to restore it? I've found so much injector data for the 12613412 in the wrong format, I can't find anything for the E38. I don't have the "12311 - Injector Flow Rate vs. KPA VAC" table, I have "12307 - Injector Flow Rate vs. Pressure Delta."Originally Posted by blindsquirrel
Thanks!
Here ya go
Thanks! That's way off what the tuner has in my tune for these injectors. I have a lot to dig into!
post your tune
I'm new to GM stuff, helping a friend out. Biggest complaints are hard hot starts and transmission that fails to shift at WOT.
At first glance, it looks like the injector data doesn't match and the MAF curve has been altered (not sure how much you'd change the MAF curve to account for a K&N). I figure it's better to get the basics right first before trying to add band-aids.
Whats all done to the truck?
Engine size shows to be 416ci.

I'm reading and watching as much as I can - didn't want to come in here with the simple questions that annoy everyone.
Got a datalog of it not wanting to shift at WOT and the hot starts?
Confirm the ATF level is correct as well.
Just a little history - the original 6.2 did 6.2 things and collapsed a lifter/wiped the cam. Decided to go big with the stroker, first iteration died pretty quick, builder did a bad job. Did the next overbore and new pistons, went okayish, started knocking again, parked the truck for a few years. This year we pulled the engine out and found the knocking was just loose flex plate bolts. Did a once-over, found the builder installed the rear main backwards, but everything else checked out. Got it all put back together and we're trying to iron out the bugs. Log attached of a harder hot start, sometimes applying throttle helps. Log attached of full throttle shifts - I'm not sure if enough channels got logged to diagnose. I thiiink it wouldn't shift in D but would shift in M if you tapped the +/-, it's been a few years.
