Which is better? I know the capabilities of the ZZP ECU but not much about the Stage 3.
I basically wanna know what the Stage 3 will do besides shut off the 02 sensors, raise the rpm limit, shut off a/c, ability to do 50 shot, and a 100 octane mode.
The zzp ecu does the following: Does the Stage 3 do any of this like the **** in bold
Speed limiter removed
Raised rev limiter to 7200
Altered fan turn on keeps the IC radiator cooler at all times
WOT fueling is revamped to provide a safe, flat air/fuel ratio at all RPMs
Codes removed for catalists allow high flow cats, no cats, or stock to work without setting codes (P0420)
Torque abuse modes are modified to eliminate bog during WOT
12 PSI boost limit is removed (after the 6,000 rpm or so where it bleeds off boost)
Timing revamped for increased power
MAF/MAP tables adjusted for running smaller pulleys
Idle hunting from installation of larger injectors improved

I heard that a stage 3 cobalt with a 50 shot can do 12.0 seconds... Thats crazy... I want to run a 2.9 w/ the stage 3 or the ZZP ecu and if i end up getting the zzp i hope to be in the mid 13's

Any info would be greatly appreciated...

 

Come on anybody????

 

Is anybody running the ZZP ECU? Im wanting to go stage 3...but this might be worth a look.

 

I know there are a few guys on here running the ZZP pcm. From what I have heard your better off to go with the S3 pcm. But that is just what I have heard, I personally would rather get a dyno tune.

 

dyno tune for the win!!!!

 

I been told canned tunes besides GM are bad news

 

so wheres the best place to get a gm s3 pcm and what can i expect to pay

 

the bad thing about the stage three is no a/c and it locks it up and you wont be able to tune any more.

 

I actually think i've made up my mind... I'm gonna get a GM stage 3 ecu... basically because of the 50 shot.. and the ability to do 12.0 seconds.. I don't really wanna get a canned tune or anything... And don't really wanna do anything internal to the motor so i think the GM stage 3 would be good..

 

you can swap the pcm's out in 5 minutes if u need a/c. and crateenginedepot is the place to get it, make sure you get the right year

 

Neither, HPtuners.

 

you are not going to run a 12.0, maybe low 13's if you can drive.

 

If i get the stage 3 ecu... do i have to have the intercooler dual pass? Can i subsitute it with a heat exchanger... i heard that works better

 

^^no you can buy the pcm seperate. there are opinions on what works best for cooling, but h/e is better bang/buck

 

Yes cooling is definate when you run the Stage 3 ECU

 

S3 you can set the rev limiter yourself to anywhere as high as 8k, search it, it is somewheres around here

 

I looked into Stage 3 up here, it was 1500.00 (+ install).... Interesting. If I was looking for a canned tune, I would go GMPP Stage 3. I would also throw a 50 shot on :P

 

the stage 3 "kit" from crateenginedepot.com is definitely a better deal than just the computer, if you think you want a dual pass i say go with the kit and sell off the pulley maybe and get a nate pulley on ebay if you don't want the heavy 2.99" one they give you. Since its a GM product, i've seen the stage 3 pulley's sold for almost $100 on ebay, retails at $111-120
