ok heres the thing im new with all this. i recently got me a cobalt ss/sc and installed the stage 2 kit and was wondering about upgradeing to the stage 3 kit but was wondering about how it says the stage 3 kit if ment for off road use only but i was needing to know if you could use it for every day driving too? what i am doing is trying to make it like a race car but still use it for every day use any suggestions on what i should do or just stay with the stage 2 kit?

 

What it means by off road use only is because it has the ability to control nitrous and we all know that it isnt street legal and the kit will void your warrnaty, but you can still use it as a dd

 

ah thanks one more question i did some reading on the stage 3 kit i found out that by in stalling it the a/c will not work, and one of the main reasons for wanting to install the stage 3 kit was to get the adjustable rev limiter is there another kit or way to still get the adjustable rev limiter and keep my a/c?

 

There is a thread here some where, you would have to search for it .. but a guy who used to be a gm tech did a whole right up on the stage 3 kit with nitrous install and how to retain the ac .. but its not for the faint of heart .. it looked pretty tedious

 

oh ok i see, some people are talking about a stage 2 reflash pcm or something what is that?

 

that involved re-wireing the a/c compressor so you could turn it on with a toggle switch. part of gm's reasoning for disabling the a/c was so people dont run it on the street. the reason it says its for offroad use only is becuase its not emissions legal.

 

dang so i sould just stay with the stage 2

 

Something like that .. like i said .. it is possible to retain the ac with stage 3 .. but it is a pita from the how to that i read

 

will gm ever make the stage 3 street legal?

 

One of the nice things about the stage 3 setup is that you can always swap your PCM. When daily driving use the stage 2 PCM and when racing or going to the track use the stage 3 PCM. Your other option, as stated before, would be to wire in a switch for the A/C.

No, not unless running nitrous becomes 50 state legal.

 

so your saying that i can switch out pcm and it will not mess up any seting or anything

 

no .. you just wont be able to adjust your rev limiter or use the nitrous with the stage 2 pcm .. but it will work just fine

 

Is this a "GM" stage 3 kit?? If so where can I get some info on it??

 

yea .. its a gm kit .. check out crate engine depot .. they have them there

 

well that solves all my questions on stage 3 kit thanks for all that help me out...

 

Yes you can switch it out. When you have the Stage 2 PCM the car will run with the stage 2 tune (7000 rev limit) and when you put in the Stage 3 PCM you will be running with the stage 3 tune (adjustable rev limiter, slightly leaner tune, no a/c and nitrous tune ability).

One thing of note is that your oil life is stored by the PCM so by swapping them you will not be able to use those features accurately so make sure you keep track using some other method.
