its official: stage 3 info!!!
so yeah i was really questioning getting the stage 3 ecm because of alot of issues that i will cover here:
1. Stage three turns off rear O2
2. Idle quality is great
3. Gas milage improved by nearly 5mpg avg
4. Adjustable rev limit is so cool mine is set for 7250
5. 100 octane mode pulls really hard on top end
6. nitrous plus 100 octane is a GTO with cat back
so as you can see i am thrilled with the results my previous tune was showing 229hp on scan gauge even though i dynod car and got 240whp now im showing 269hp on 93 and 274hp on 100 octane tune but with 93 in the tank... any questions please feel free to ask or pm...
and yes i really raced my friends gto who used to get me by two cars at 100mph now ive got almost two cars on him

i'm glad its working out for you, and i always love to hear of GMs customer satisfaction. I like that you dynoed the 100 octane as well, i've always wondered what the true gains were, i was told 10hp but i've never seen real life results. Are all of those stage 3 results from a scan gauge or dyno? If so would you happen to have the printouts?

I have the ECU as well. You said that you dynoed at 274hp or was this 274whp . Also do you have ZZP header on your car?
How do you know that it turns off the o2 sensor in the down pipe. You have the high flow cat down pipe that you put the stock O2 sencor back into right?
Your sig states that you are running 2 stages for nitrous?
The GM stage 3 tune only allows for 50 shot dry that is hooked up through the ECU
What Nitrous sytem do you have?
Also in 100 oct mode the ECU detects that you are running 93 octane and will default to normal mode unless you have 100octane in the tank.The light will turrn off
Although you might be right I have never tried my 100 mode unless I have 100 octane in it and it was completly bone dry of 93 before I put 100 in .
If you do have the nitrous set up then how hard was it to hook into the stock wiring harness with the connectos that they give you and also what color are the wires that you have to tap into in order to make it work?
Can't wait to see the numbers with the nitrous. Are you running on the stock clutch? How many miles are on your stock clutch?
Finally what year GTO (5.7 or 6.0)and what was done to it and how many miles are on it and was it a manual or auto ?

Do a search here. you can make it so that you can by pass the ECU and turn the air on . Looks like a lot of work and does not look good with addtional gauges and switches just to turn the air on. Someone was telling me that hopefully HPT will be able to tapp into the ECU by summer and be able to turn the air on. While other say the ECU is locked and HPT knows this and does not want to spend anymore time on it.

how does the STAGE 3 compare to ZZP ecu? Does it also eliminate torque management? Does it do all of this basically:
(the ZZP ecu does)
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
Timing revamped for increased power
MAF/MAP tables adjusted for running smaller pulleys
Idle hunting from installation of larger injectors improved

As far as I know GM stage 3 ECU does not:
remove the o2 sensors for delete of the cat
remove the 12 psi boost limit
remove the torque abuse modes
Timing is advanced by the ECU for 100 octane mode
It really is only calibrated for the GM stage 3 pulley which I believe is a 2.999. But other guys have been running other pulleys like myself (2.9 zzp)and have had no problems

It is great to see some people buying the Stage 3 kit from GM Performance. How much labor did the dealership charge to install the parts? How much did they charge you for the parts (or did you buy them cheaper online, and then have the dealer install them)?
Does your heater still work with Stage 3? What kind of quarter mile times does your scan gauge indicate on the Stage 3 tune? What scan gauge did you buy? I am trying to figure out which scan gauge works best.
Thanks guys!
Eric

100 octane mode with 93 in the tank. wow
either its going to disengage due to knock.
or its gonna knock itself to death.
i would stop doing that if i were you. wth were you thinking?
do you understand what your doing when you turn that on?

With Stage 3:
Hungryhip already confirmed that post o2 sensor codes are removed
The 12 psi boost limit must be gone due to its ability to properly use a 2.999" pulley. Stage 2 at least has this already to run the 3.07" pulley. ZZP lists it for people trading out fully stock ECM's
torque abuse modes i'm not sure of, I'm sure there may be further modifications to the ECM from the stage 2 standards, but i'm not sure how far they go

I tried to runn the GM Stage 3 with 100 octane mode and as soon as I left the first run this past summer I broke a axle shaft out of the hole so no times for me but FNFAST ran his with nitrous and slicks and put it at an even 12.0 sec quarter mile

the hp #s im sure are probaly flywheel i dont see how it could calculate whp
the gto is a stick with 6.0 and cat back i know him personally and everything done to his car he wants to put his slicks on and go again but he dosent wanna let me use my slicks wich i told him is no fair...
yeah stock clutch with 8k mi and its got plenty of clutch material left just not enough pressure plate clamping force so it used to slip from the 1-2 shift on the spray

thanx, I think what i'm gonna do is call GM and see what they say.. A couple of people say different things and i just wanna be 100% sure... If the stage 3 ecu does what the ZZP ecu does plus make the RPM Limit change and a 50 shot of nitrous i should just get the stage 3 and most likely be quicker... But i want the car to be at its full potential w/o getting a tune and having torque managment on... thanks again for not ignoring my questions and changing the subject

Well say good bye to yuor clutch.
I guess I will be one of a hand full on this forum this summer that will have the true GM Stage 3 with nitrous setup through the ECU's around here.
Yea check the 1/4 mile threads FNFAST did it on slicks
FNFAST,12.05@115.22 W/1.83 60',GM3/2.8"/T/H/E/N20/WR/DR=GM STAGE3 tune , Header, exhaust,weight reduction(removal of spare tire, pass seat , rear seat trunck carpet, sub wolfer) Drag slicks with 50 dry shot
