Bump

Thanks Bill,

When I say "full" SD, I mean without running the MAF at all. As I understand it, you can run in SD with the maf (similar to the factory logic), or without the maf. But running...

Ok, so I've got an 04 GTO that we're running a 2bar OS on, and I'm running into a few problems I was hoping someone could clarify. I'll itemize them out to help.

1. I've failed the MAF via...

I've done that for now, but eventually I would like to have a low "failsafe" table to go back to, if it ever does with the 2bar OS?

Specs:
ls1-383 stroker
twin turbo
2-bar GM map
80lb inj
9:1 comp
built
NO MAF
6000ft elevation
2004 GTO

Bump....come on does no one know this?

Ive searched and haven't found anything definite, is the 6.2l f150 raptors supported?

So I'm reading posts (older and elsewhere) saying that Trifecta is the only one who has access to the fuel rail pressure adjustments? I see a "desired" rail adjustment, but when I tweak it and raise...

Fixed, Dealer flashed the new (used) ECU to the correct VIN and VATS info. Starts runs, and I'm able to tune.

Ok, still having problems. I got a new ECU, HPT doesn't have the def file to support it...
I got ANOTHER ECU, this time from a SC Redline of the same year, I was finally able to read it!

But now...

I've been told they unlocked the HHR's and possibly the cobalts, but not the redlines.

So I've found a slew of LSJ P12 PCM's, but apparently they fit a whole bunch of vehicles? So how would I go about programing one of these to fit the SS? I've got a stock 07 SS file from another car...

LOL!

:shrug:

At this point the only thing that seems reasonable is that the customer accidentally put 85 octane in it. I'm pretty sure it's true knock since it goes away with almost no timing, but even when I'm...

But what I don't get is the knock? Why so much knock on stock tune? Is this normal or acceptable? It's not with any other car I tune on HPT. And I'm pretty sure at this point it is true knock,...

Two logs, one stock, one with the GMPP tune (most of it, not the MAP recal).

Dyno Graph

Pink is with the tune, blue/green is stock. Top graph is power/tq, bottom is AFR and Boost. Seems like the pink has MUCH more boost @60mph + but not so much on power.

Also the...

Ok, so new to this LNF engine, and I read through all the how to blogs...still having issues, just wondering if anyone else has seen this stuff.

1st, the car is an Auto, and it seems no way to...

If there's no core with another ordering another one, you want this one?

I just don't want to go order a PCM to find out that's not the problem.

But wouldn't that give me a code besides 11? From what I've read Code 11 isn't even a real code that exists.


CK

Alright, I've tried 4 computers, and 3 different cables, and both versions (2.22 & 2.23), all pretty much the same result. One won't validate (original problem, prob because he doesn't have the...

I'm not sure if it's been tuned, I can't download to find out what's on there. But from the way it's running I would say no.

Do I need to uninstall the Beta completely first, or just write over...

Ok, so now the scaner works, and I'm able to connect, but now it says "Security Codes Denied - Unknown Error : 11" I read other posts on this, and they say do a read, then a write....but I can't...

Thank you,

I'll try it, and get back with you.
