Default Does anyone know if perf shift table can be used in LS1 edit?

Can the perf shift table be used if wire in a perf shift switch. The table on my 98 is all 255's. It would be nice to have both tables so you could make one "STUPID". Input please!!

You got it! You just need to wire up a performance/normal select switch and you will be golden.

OK, Chris, you got a diagram for that?

So far I have not found the correct pin on the PCM for it yet.

I'm with you Ryan. I have Gm Techline terminal and can not find anything but a second gear start on the 3.8 litre. There are alot of "NOT USED" pins in the connector but can't find which one. I also got a schematic from the Holden director to see if that would work with no availl. I don't believe there was a perf shift in a LS1 car. Input please.

Nope, don't have a schematic - I just remembered hearing of someone set it up, but of course can't find any information.

Logically I would assume there is a way to engage it - else why put it in the pcm; but again, who knows.

What about some sort of towing/normal mode switch on the trucks?

Ive got a Holden SS Commodore with the 5.7
It does have a performance switch. On our pcm's this switch affects the shifting pressure and rpm.
