Does anyone have a spare PCM I can borrow until I get mine tuned? :D

As the title states, I need a PCM for my 03 TB 4.2L so I can send mine in to pcmforless to get tuned! I don't wanna pay their $50 loaner fee :hissyfit:

If anyone wants to be a good soul and let me borrow one for a week or so, that'd be great :biggrin: I'm located in Clark, NJ, but shipping is okay too :biggrin:

Uh, you can't just slap in any ol' PCM and go. It has to be programmed with your VIN, options, etc. And to have it programmed at the dealer would cost just as much or more than the loaner.

I would just get the loaner. I believe as long as you send it back you will get the loaner fee back, but not 100% positive.

I was unaware that each PCM has to be programmed to the individual vehicle. :banghead:

I will call/email pcmforless tomorrow to see what they can work out with me. Thank you for the replies!! :thankyou:

It's true that PCM4Less needs your VIN number in order to send a loaner. But this is only for determining the specific options you have so it will drive/control your outputs.

I don't agree that you need to have a specific VIN programmed in the PCM in order to use it. Just a valid VIN similar to yours should do. This includes a valid VIN which has a correct check digit. The VIN tells the PCM which engine and trans you are using via the production line sequence so it can operate and be programmed accordingly

Therefore the OP's original question stands and is valid. Someone else could loan him a PCM and it would work. But the vehicles need to be similar. To what extent, I do not know. I believe that's why most just play it safe and program in their own VIN.

:iagree:

I picked up a cheap PCM in the trailvoy.com classifieds way back when. Dropped it in and after a security relearn was up and running while my PCM was out for a tune. I would just keep it within the model year blocks 02-05, 06-07, 08-09 (iirc). Any 02-05 PCM for a 4.2L should work fine for the OP for a few days.:thumbsup:

I'd let you borrow mine but it's an 06 :sadcry:

Not too sure about not needing to program the VIN. Isn't there something between the BCM and PCM that requires the correct VIN for VATS? Probably Pcm4less can answer that one for sure.

Looks like AtlWrk already answered the VATS question. PCM4Less sends you the instructions on how to do the security relearn so just a valid VIN similar to yours is required.

Awesome! :biggrin: Now all I need is to find a cheap PCM to buy, or an awesome person on here with a 02-05 4.2L to let me borrow their spare one if possible :wootwoot:

Ive got a few 02-05 P10s Id be willing to part with and Id program it to your VIN if you want. PM me if you're serious, Id like to get $30+shipping for one. :thumbsup:

That would be my choice. Then if you don't like the tune for what ever reason, pop your original back in and deal with it.

you'll have to eventually get the new one crank learned.

Or just buy a tune through me on one of those cores... but yep, Ive got 1 or 2 P10s Id let go for $30+shipping. Have to check and see how much I have into them total, think I have 4 extras here at home now. Flat rate USPS is max of $12 IIRC.

True, but I guarantee you that once you drive a tuned one, you'll never drive a stock one again. The change in throttle response and driveability alone makes it worth the $$.

Very good point, if you swap PCMs at all the new one has to have a crank relearn performed.

Awesome! I'll definitely PM you when I'm ready to go through with this, I'm a tiny bit tight on money at the moment because of Xmas shopping :frown: but I most definitely NEED to get it done before I drive down south to visit family after Christmas!! :biggrin:
