Don't trip, there maybe other things going on but it all leads to the same goal of what the forum wants. All I can say is send him the PCM and we can trouble shoot as we see fit. Remember this is still a process that we are all trying to solve. It will benefit all of us.

John has the SLS locally. I am hoping his sees this

GM spent lots of time on these calibrations. It'll take a lot of trial and error (not on my vehicle!) before AJ comes up with something tenable.

I think it sucked oil into #7
Tha data looks ok other than it is eating a piston

[AJxtcman]

Just before

What all did you change on that SLS? ONLY the speed limiter? Or other calibrations as well? I would think that if one piston sucked oil, the rest would have as well, unless you think a ring broke...but I think you'd see evidence of that.

In addition, I hope you're using tires appropriate for these speed runs...and/or keeping the car at 150 only very very briefly. I assume you're doing this on a lift, so the tires are just free-hanging? A tire that is only S-rated (which I assume anyone with an SLS will probably have), could easily fail when spun to well over its speed rating.

The engine that broke is in my FIERO. I am running a 99 SLS korean BASE program.
I will check and make sure.
I guess I won't. I left the key on when I pushed it into another stall this morning.
.
I have another engine I will build this week and install.

I have to be freindly. I found a washer in the intake manifold. I can see a wear mark in the intake port. This would mean that I had more than 1 in the intake. As I said the engine was taped up. The intake was not. I have had some major problems with other Tech in my shop and THIS CAR!

aj........something is very wrong here. What relationship does a Fiero mid-engine setup have to a late '90's-on 4,000 lb. FWD full sedan rig? Several posts here have compared apples and oranges.......and the apples blew up !!! -----------------P.S.-------------I just caught your post about a washer in the intake manifold. You can quote me: THE ONLY REASON FOR A WASHER OR NUT IN THE INTAKE MANIFOLD AFTER A REBUILD IS SLOPPY WORK. I have tried to maintain an open mind on this PCM program odyssey, but the longer it goes, the less I like the potential outcome. I, personally, would never trust a $10,000 - $25,000 vehicle to a "shadetree" tuner. If my car blew up, would you replace it? Diss me if you will, but it's an honest question.

THIS WAS A GM CRATE ENGINE!!!!
I HAVE SEVERAL NORTHSTARS ENGINES SITTING AROUND!!!
IF YOU HAD ANY IDEA HOW F****** UPSET I AM!
I HAVE NO PROOF OF WHO DID THIS!
THE TWO THAT WORK ACCROSS FROM ME HAVE REALLY HAD A PROBLEM WITH THIS PROJECT!!!!!!
ONE OF THEM ROYALLY SCREWED ME UP AND COST ME ABOUT 40 HRS ON THIS!!
THE OTHER GUY WE ALMOST CAME TO BLOWS OVER IT AND THE SERVICE DIRECTOR HAD TO COME OUT AND SETTLE US DOWN!!
.
I GOT A ENGINE WITH UNDER 5000 MILES ON IT FOR FREE!
I GOT A TRANS FOR FREE.
I HAD TO REPAIR THE ENGINE!!!
.
THE TWO ACROSS FROM ME ARE TIGHT AND TALK ALL DAY LONG.
.
I GOT SOMETHING FOR NOTHING AND THEY ARE UPSET!!!!!!!!
.
THAT HAS BEEN THE BOTTUM LINE!!!!!!!!!!!!!!!!!!!
.
.
.
I AM USING A GM PROGRAM TO DO THE CALIBRATION MODIFICATIONS.
.
.
THIS BLOCK WAS TAPPED UP TIGHT

You do understand I have a Northstar powered FIERO. Also know as a P car.
The P stands for Piece of s***.
The washer I found is a special washer. It was attached to a nut or bolt. It is not flat and it is black. I will find what it came from. It is strange to find it in My engine. I have done so many customer cars with no problems.
I built this car to pay for a wedding.

As the saying goes, TANSTAAFL. That's karma for ya. I'd suggest buying a core from another dealership. Avoid the problem individuals altogether

I have more engines.
I have even more than what is in the pictures.

Give the guy a break. I think he's for real, at least on what he's trying to accomplish. Me personally, now that I know what the result of this pcm tune he's doing, Im not to interested.......I dont think having the spark timing of a 50ft cady limo, will help me much. Nor will having the air/fuel ratio of a model with a tow package, give me any real performance. I will wait till someone can actually adjust our current set up. But good luck with this anyways....
