Needs to be attached directly to the forum. Most on here won't mess with links. Stick with your Gen 4 post. And needs a tune attached also.

its rich because youre running a stock tune with that aftermarket camshaft. you have to tune it which i can do. put back old imjectors.

Well you still need the tune the thing. I added 10% to the VVE which should help in the meantime, but it will still require work. Heck we don't even...

Good suggestion. I’m running 93 which is the highest locally. If there’s an octane booster that actually does something I’d give it a try.

Did you log wastegate duty cycle and Throttle angle?

Such a dumb way to have it setup backwords like that, but that fixed it lol. Burnouts are no problem now! The off idle hesitation however, is still...

I did "write entire" twice. Disabled starter checks. This is a swap. 2011 LS6.0 going into a '68 GMC Suburban

IAC is maxed out meaning it cannot allow enough air in for it to idle.. It looks rich which is going to make that situation worse. TPS is...

PE is still set to be delayed to 5500 rpms, with an odd enrichment afr. But, as those have stated above. tunes dont die. Engines do. Check...

You could also increase octane and see if it reduces knock.

It's my daily. I'm just looking to add some power while in "Sport" mode, and hopefully smooth out some of the janky shifting in the trans. Maybe...

Thanks Alvin! I?ll pull a bunch of timing in those areas and see if nothing changes. I?ve been dropping 2? a time but I think I need to go more...

As mentioned above, check the obvious stuff first if you had it running before, blown off hoses, fouled plugs, your TPS is also reading 0.8%, this...

Basic checks. compression test Leak down test fuel pressure test pull the valve covers and check springs Tunes dont just go bad in the middle...

Does it run any better? Hers your tune with the VE changes from the log applied. Its still gonna be pretty far off. Load the tune, Clear the fuel...

Disable the starter checks too since it looks like it's a swap. +1 on the write entire too.

Max out parameters could either cause issues because hardware is being stressed out unnecessarily or software could induce issues its own

Replied to your other thread. Sounds like you aren't doing a "write entire" with the disabled VATS file.

Are you writing entire to disable VATS? No one can say if you are overlooking something without posting tune and log.

Did you do a "write entire" or "write cal"?

Now I am able to get engine to run for a second or two. Seems like the security system is shutting it down. I have gone into the "OS" tab an disabled...

If it won't go away with pulling timing in that particular spot check for things banging or making noise. Engine noises can cause this. Also as...

data log would help,

Looking forward to it. Thanks for the updates!

No changes.
