Thread: Swapped 05 L32 into an 04 L26 HELP???

Like it says I swapped an 05 S/C engine into an 04 n/a car. I left The engine harness on the S/C engine and unplugged the harness from the relay box under the hood. I checked the relay boxes and they were identical according to the fuse/relay charts. Swapped the entire cradle, engine, trans, harness and PCM from the 05 S/C car. From everything I could find to read up on, I thought it was a plug and play. Evidently I was WRONG. Everything plugged up fine but when I turn the key on I can't hear the fuel pump turn on. Turn the engine to start entire dash goes out (can't remember if that's normal) but nothing happens. Can't hear any relays. Nothing. SO... HELP!!!!

Cool thanks. I will check that first thing in the morning.

I may run over there in a few mins and try it. It's in a friends garage. (he has a lift) Made the swap ALLOT easier. Took some pics of the swap. Will post a link later. Thanks again.

Yep. Allot easier than I thought. Did it by myself. A friend of mine was suppose to help, but he had a family member pass away. Question, if swapping the PCM works, would I be able to run it long enough to back it out of his garage and pull it onto my car trailer? Thanks again.

Great. I actually have a Digital Horsepower Tuner. I have never used it. But Is this Vin change something I could do? Thanks again.

Another question. Where is the BCM located?

the L26 PCM is also not tuned for the larger injectors on the L32. it might not even run.

YEP, that was it. Plugged the 04 n/a PCM into harness- the car started right up. So it does need the BCM from the 05 or have the 04 Vin flashed into the 05 PCM. I wished that would have been in a writeup somewhere. I would have put the BCM with the PCM whe I took it out of the car. Now I'm not sure what I've done with it. SO can anyone change the Vin in the 05 PCM for me with the 04 Vin??? Thanks for all the input already folks.

Without HPT your best bet at this point may be a PCM from Reptile or a vendor.

Just don't get in to boost until you get a supercharged tune on there it you'll lean out

Humm, I can't get the laptop to recognize the interface with the DHP Tuner. It asks for which comm port it's hooked up to. I can't figure out which USB port is which comm port. I hooked the usb cable up and tried 1-16 on the designated comm port from DHP Tuner. It wouldn't recognize it at all. Anyone have any thoughts? Thanks.
