Up for grabs a GM stage 3 PCM for 2005 cobalt, it works on 2006 too, the only thing is fuel gauge in car reads backwards. I used it many times no problems, I'll throw in the nitrous wires too.
The price is $120 shipped.

 

Bump for GMS3 & its awesome features !!

Good luck with the sale. Great price by the way.

 

Thanxs!

 

What kinda tune is on it. What comes with it ?

 

usually once the pcm is installed and taken off the tune is no longer on so you would have to get a tuner for another

 

you need the GM stage 2 injectors and pulley for this to work on your car.

 

Correction:

GM Stage 2 injectors, hub, and belt + GM Stage 3 76mm pulley.

 

The GMS3 tune is on it.

It comes with an adjustable rev limiter, high octane mode, and nitrous feature.

 

huh??

I'm not sure what you mean, but what I see you saying is when you uninstall a PCM & install it on a different car you loose the tune. This is incorrect.

The GMS3 PCM is completely plug and play. This means you can install it w/o worrying about getting a Crank Case Relearn at the dealership.

 

76mm what pulley size would that be if i had a zzp 2.8 or 2.7 or do i need the gm one

 

I was using a 2.9 pulley

 

76mm = 2.992125984 inches. So a 3.0" but many run 2.9" but you might want some cooling mods.

 

cool if this guy on here buys my wing im in 120 right

 

cool beans !

 

did you dyno with the 2.85?? and what power you get?

 

no dyno yet, waiting on a trifecta tune right now.

 

ok so i was researching the pcm with it already having the calibration for the 50 shot if i wanted to all i need is the kit right and as well does it totally disable the ac or does it at WOT or a certain rpm

 

Totally disables the A/C its supposed to be offroad.

 

You can get the A/C back.

See the Trifecta + GMS3 thread.

I have GMS3 with A/C.

 

still for sale!

 

haha what? It's not a comcast cable box, when you unplug your computer do you lose all your files saved on your hard drive?

 

At least you understood what he was trying to say... I was like wtf?

 

hey i ment to buy this when it was on ebay but wasnt sure if the gmstg3 would throw a cat code for im catless. I have crappy zzp tune rite now but atleast the cat code is turned off. Thats my only hold up on this, i know you told me on ebay you were high flow and it didnt trigger it, guess im just lookn for more assurence, also this is for the 50 shot correct? Have others ran more? Pm me and when i get off work and off this blackberry junk we can fig it out for its what i need and you just happen to have one lol thanks

 

I'm surprised this is still for sale ... I would have bought this in a heartbeat back when i had my LSJ.

 

Same here man.

A lot of people on this site dont understand how great of a tune GMS3 really is.

Trifecta made it even better by regaining the A/C back, and allowing for custom tunes.
