97/98 LS1 Corvette PCM swap

Hi Team

We have been asked to help out with a PCM swap for a 97/98 LS1 Corvette, we will be replacing with a 2001 Holden LS1 PCM (Serv No 12200411), this is due to PCM failures whilst using HP tuners (yes I have notified support, whom have no answers for me unfortunately)

I have pinouts already

I have attached the standard 97/98 tune, does any one have any info as to what Year/OS tune we need to write to the newer 411 PCM to carry out this conversion

I have tried doing a write entire of the 97/98 OS to the newer 411 pcm, it does not work at all

Any info would be much appreciated

Phil

most use the 2002 LS6 Corvette tune file

If you really tried that don't attempt any more writing until you have a lot better understanding of how this all works.

Thanks for your reply.

Rest assured i did this on advice from hp tuners support team, which obviously is incorrect

Do you have any input or relevant file to help?

Thanks

Thanks

Do you have a copy of said file or OS number?

Thanks

I actually have a 1998 LS1 Firebird PCM in my garage if you need to get a replacement for the original.

If you are still going the 0411 swap route, you should be able to use any of the Holden Commodore 00-02 LS1b tunes for this.
Once you have the OS on there, you can open the corvette file and copy and paste the spark/fuel values etc back over and make any changes needed manually.
Might be a bit time consuming but I think that would do the job.

I have a fair few of the files somewhere at home when I was searching for a starting tune for my 0411PCM swap if you need one I can send.

Disclaimer: by no means an expert, most other guys here would be better suited to answer the questions, but as an aussie I might know a thing or two about the commodores the others don't :)

Much appreciated

If you wouldn’t mind sending to [email protected]

We are using a vx ecu

Sorry dyno, been flat out with getting my car on the road and forgot about you LOL

Here's a VX commodore tune and a 99 camaro tune.

You could try either of these and then copy and paste your spark and fuel tables over and should be good to go.
