Nope.

 

[Mechanicboy]

Nope.

Agreed.

What do you think controls ignition and fuel firing? You would be missing 2 drivers for each even IF everything else was the same, which is not even close.

i didnt think it was ganna work either but when i put a sst shifter on my ls the computer recognized it and works great.......

 

[1305leo]

do you know if the new pcm has to be programed?

The SST shifter was available on 2000-2002 V6s as well as the V8. That's why the computer recognizes the self-shifting. You still lose D4 without a sport calibration.

Yes.

i heard that some pcm can only be used with some engine . is his true??

You can't change from V6 to V8, and you can't change generations. All PCMs have to be "married" to the car's cluster.

 

[1305leo]

so even if you change clusters you can change from v6 to v8

 

[drag214]

so even if you change clusters you can change from v6 to v8

This is a joke, right?

Alax! Is that you?

 

[1305leo]

k

did you do this swap ?? wut to expect?/

did you do this swap ?? wut to expect?/

The V6 cluster, pcm, ecu, etc. is NOT interchangeable between the V6 and V8.

 

[1305leo]

so your telling me the swap is impossible??

 

[cammerfe]

Nothing is impossible. Just jack up the radiator cap on your V-6 car and slip in an entire V-8 car. Problem solved, and it isn't even very much labor!!
