1998 LS1 to 2000+ LS1 conversion?

G'day Mick,

That table is only visible using the factory software tools...?

It would be interesting to have access to it...

Cheers
Joe

Hay Joe,

There is a parameter table called installed options matrix which is tied into the platform code that has much to do with the pin out options. The platform code is number from 1 to 10 and on the other axis there is a swag of options to either enable or disable.

You find things like the lean cruise option and a few other things in there.

This is one area that will change the pin out in a PCM.

Joe,

That table is available to who ever includes it into there definition template.

I see it in TC software.

Here is a snapshot of the table from a 02 vett Z06.

There is also a parameter constant to select the platform code.

Yes...makes things interesting if your chasing LC on a US operating system but that is another story....

I'm sure you get the drift.

Cheers

Mick,

Very interesting indeed (hmmm, I see...)...

I wonder if there is an option for running MAF/MAFless...?

(the reason I ask is that when failing the MAF, the resulting DTC's seem to inhibit some of the trans features like adaptive shift learning).

Cheers,
Joe

Guys,

I truly wish I could post the dyno charts for this car, but I have been sworn to secrecy until after he runs it at the strip. What a change from the HP Tuners 2 bar conglomeration of crap for the 1998 PCM to this. As soon as I get the go ahead from the client I will post up the before and after graphs.

My much appreciated thanks to all who led me down this path! You guys helped me be the hero on this one!

Best,
-Kenny

Joe,

I see a speed density parameter option in the constants for the V6 only.

The V6 platforms I have seen run up to 140kpa with a S/C option as well.

There is quite a difference in the V8 platform.

One can only assume that the Maf calculations are very important in the trans shift patterens with respect to calculated load and learning on a OEM platform.

Cheers

Mick,

Oh, we also found that failing the MAF seems to disable misfire detection.

Dale do you have a copy of the tune file or VIN from this other 7.4 (L29)engine?

Sorry, havent been back on sense I posted this. I found a PCM out of a k2500 truck, got it in yesterday. Havent had time to scan it due to graduations.

Plan to in next few days and try to submit it to holdencrazy.

Ive been told the crank signal between the 7.4 in the k2500(4x) and crank signal 7.4/utility trucks(24x) is different.
