Swapping PCM's??
 
I have a 2000 m6 camaro... I bought a torquer v2 cam from a buddy out of his 2002 m6 ta... My quetion is.. Can I put the cam and other cam supporting mods in my car and just swap him pcm's and be fine..

No.

Different pin-out on the PCM. Also VATS will be an issue.

You can re-pin and reprogram, and delete VATS if you really wanted to swap, but I would just stick with your PCM and put a tune in it.

Ya I heard the repinning thing was ridiculous... I have read several ways to delete vats but everyone has something negative to say about each way... Atleast wat i have found on here... Wats the best/easiest way to delete it... Mine is messing up bad.

The easiest way to delete VATS is to have HP tuners just turn it off.

No negative side effects that I would complain about doing it that way.

Is the VATS glitching because of the resistor connection on the key? There is an easier way to deal with that.

Do you even have a clue?
What exactly do you think he needs to repin? This isn't a 98 he's doing.

Why would he have to delete the VATS? The F-bodies use a PWM Vats signal and don't match VIN's like some of the other vehicles, that use the serial Vats.
2000 and 2002 use the same basic pin outs, even though they are differant PCM's, but the 2002 isn't going to support the EGR function.

NoGo Aug 22, 2010 05:54 PM

Fine. Go swap PCM's.

I'll be here when you get back on the forums.

NoGo Aug 22, 2010 06:09 PM

Just did a forum search, the powers-that-be say you should be fine.

I thought I remember bumping into a problem doing this, but I haven't done it for years without just writing a different OS to the PCM. My recollection is that you can swap 99 with 00 with no issue and 01 with 02 with no issue.

Apparently I don't have a clue.

Actually you can put the 2001 and 2002 OS'as in the 99 and 2000 PCM's, but not vis-versa, its a common swap to get the extra tables

So did you research the Vats and pinouts, while you were at it?

The best way to fix the vats is to put the resister across the wires for the switch. If you turn it off in the PCM, you still will not get the crank relay, which is controlled by the BCM to engage. If you put the resister across the wires and still let the contacts hooked up for the key, you can then remove the resister pellet from the key and only a key without a pellet will work, that way if somebody tries a key with any pellet, it will not start

So from what you just said his buddy will have issues with the 2000 PCM, but a few posts up you said go ahead and do the swap?

Maybe reading owns you, I said swaping the OS in the PCM, can be a problem, if you're putting the older OS in the newer PCM, nowhere did I say swapping the PCM's would be an issue.

Actually, it is your award-winning internet e-peen that is pwning!!!1!! me.

Thanks for the clarification.

Hey poconojoe. Ever get tired of being a dick? If you will do some searching you will find that NoGo was figuring out how to tune this shit when all we had for these cars was LS1Edit.

I guess he should have known then, that you don't have to repin to switch berween 2000 and 2002 PCM's

JoshuaCole67 Aug 22, 2010 09:44 PM

I talked to my buddy n he said his car was a 2000... should have asked before hand.. so with that being said.. i shouldnt have a problem with it?

IDK what my vats problem is... my car will start most of the time.. my security light is almost on.. but there are times when i try and start my car and it wont allow it.. i iwll have to wait for around 3-5 minutes and the start it and it will fire right up... I just dont know which method i should use...

poconojoe Aug 22, 2010 09:49 PM

Measure the resistance of the key pellet and disconnect the wires under the column and put the correct resister across them
That should take care of the Vats for the BCM and PCM
