- - - -another point of discussion....wen i run it in 100 octane mode and with 100 octane racin gas i keep throwin codes for the o2 sensor bank1 after about ten-twenty min of runnin....any comments on that? i justr reset the code and its fine again and it only does it w 100 octane....Bad 02 sensor? or is it jus touchy???

The GM stage 3 pulley actually measures at 2.918..... not the advertised 2.99, so a 2.900 pulley is just fine. Also for you stage 3 guys you can turn on the 100 octane mode when sitting at idle with the car on (good to know at a traffic light).

another road for discussion.....wat kind of plug/gap would u guys say is the best for a stage three scenario...like the one ive got???

Oh and also just a "side" question: When you use the 100 octane mode, would this use LESS the 42 lbs injectors?? I mean... because the gaz has more octane, Im thinking that maybe the injectors have to use less gaz for the same AFR. Because I have the idea of puting a 2.85 or a 2.9 pulley instead of the 2.99" one by GM. Of course Im gonna use a wideband to see if I dont run too lean.

And anybody have ever used the 50 shot of nitrous with a smaller pulley?

GM Stage 3 was released back in 2007, but never caught on due to the lack of tunability and unlivable lack of A/C. Thanks to Trifecta Performance, it now stands poised to be THE operating system to have for any and all LSJs!

Please read the FAQ below to learn more about this incredible breakthrough!!



Trifecta Stage 3 FAQ

What is Trifecta Stage 3?
Trifecta Stage 3 is a calibration that uses the GM Stage 3 Operating System as a base for producing custom tunes and adding new custom features.What is the difference between Trifecta Stage 3 and GM Stage 3?
The key factors that set Trifecta Stage 3 apart from GM Stage 3 are the following:

• Trifecta Stage 3 re-enables the Air Conditioning system that comes disabled by default from GM. This takes a previously “OFF-ROAD ONLY” calibration and puts it back on the street where it can be thoroughly enjoyed!
• Trifecta Stage 3 is available for sale as a file that you can flash to your cars current computer, rather than as a separate Powertrain Control Module that you must swap in place of your stock one. This eliminates much of the cost that you would typically incur in purchasing a PCM from GM.
• Unlike GM’s calibration, Trifecta offers compatibility with most commercially available tuning software like HP Tuners. This means that you, the end-user can change your OWN tune as YOU see fit.

What do I need to do to access this tune with HP Tuners?

• If you have 2 spare credits, are willing to purchase 2 credits from HP Tuners, or have your entire model year licensed, we can simply send you an *.HPT file.
• If you do not meet the above criteria, you can:
  1. Find a Trifecta dealer to flash the tune to your car then extract it with HP Tuners and copy your tune over to it yourself.
  2. Send us your PCM.
     • If you decide to send us your PCM, we will copy your existing tune to the new operating system and send it back. Once you receive it, open up HP Tuners and be sure to do a "Read Entire". Save it with a file name that you would not easily confuse with your old tune on your hard drive.
• You may only use "Write Calibration" once you have done a "Write Entire". Accidentally flashing from one OS to the other using "Write Calibration" WILL irreversibly corrupt your PCM. You MUST do a "Write Entire" to flash between operating systems.
• You may use "Write Calibration" as long as you use the same tune file we sent you.

NOTE: FLASHING THIS SPECIAL HPT FILE TO ANY VEHICLE OR PCM OTHER THAN THE ONE IT WAS CREATED FOR WILL RESULT IN AN “ENG PWR REDCUED” MESSAGE AND ‘LIMP MODE’ CONDITION AT BEST, AND PERMANENT CORRUPTION OF THE OTHER CAR’S PCM AT WORST. DO NOT SHARE THIS FILE.

What if I don’t own HP Tuners? Is there a price difference for me?
Yes! There are currently four available configurations:

• TRIFECTA (HP TUNERS INACCESSIBLE): Uses the default tune from GM and enables A/C.
  For people who wish to stay at the GM Stage 3 power level but just want their A/C unlocked. This is the cheapest option.
• HP TUNERS ACCESSIBLE: Uses the default tune from GM and enables A/C. Trifecta won't be offering custom tunes for this option.
  Intended for individuals who already use HP Tuners and want to copy/paste their current tuning parameters over to the new operating system.
• HP TUNERS ACCESSIBLE + STAGE 3 FEATURE CUSTOMIZATION:: Same as above, but because HP Tuners doesn’t support them, we will perform any User Adj. rev limiter, HOM, and Nitrous customizations you request.
  
  
• TRIFECTA CUSTOM (HP TUNERS INACCESSIBLE): Custom Trifecta tune plus enabled A/C.
  For customers who want to install mods that are incompatible with the GMS3 tune, but do not or cannot tune themselves (e.g. - larger injectors, smaller pullies, methanol, TVS/Turbo swaps, etc).

What parts are required to use Trifecta Stage 3?
If you are purchasing the default GM tune with A/C unlocked, you will need the following parts:

• GM Stage 2 42# Injectors
• GM Stage 2 (77.9mm) or GM Stage 3 (76mm) pulley
• GM Stage 2 belt

If you are purchasing the HP Tuners version, you can simply copy your old tune over to the new operating system by doing the following:

• Open your Trifecta Stage 3 file in HP Tuners.
• Go to Compare --> Open Compare File, and open up your current tune file.
• Go to Compare --> View Comparison Log
• Right-click on each section and select Copy Over Differences until you have copied everything over to the new tune.
• Save and do a "Write Entire" to flash your new GM Stage 3 + A/C tune to your vehicle!

If you are purchasing a custom tune we will tailor it to your needs!

Are the special GM Stage 3 features tunable by Trifecta?
The three main features of GM Stage 3 are the User-Adjustable Rev Limiter, High Octane Mode, and Nitrous algorithm. Please familiarize yourself with their basic functions before proceeding: Stage 3 Questions & Answers

• User-Adjustable Rev Limiter
  This feature allows you to adjust your rev limiter from 6500 up to 8000 rpms in 250rpm increments. If you feel the need to change the increment size from 250 to something else, we can adjust that for you!
  
  PLEASE FOLLOW THE PRECAUTIONS REGARDING REVVING PAST 7000RPM LISTED IN THE Q&A LINK.
  
  
• High Octane Mode
  This feature adds a predefined amount of spark to your current spark map. Because it is added to whatever timing you have already dialed into your tune, rather than being a separate spark table, this feature can be used with its default setting. We do offer customization of this feature for those who would like to fine tune it by adding more/less timing!
  
  
• Nitrous Algorithm
  This feature pulls timing and adds fuel consistent with a 50 shot of nitrous. We have full control over the spark, fuel, and activation criteria (rpm, manifold pressure, & throttle position) for this feature. This means we can adjust it to accommodate for a bigger shot, or even zero out the spark and fuel tables to have this algorithm serve as an activator for anything you hook up to it!
  
  e.g. – Hook it up to your meth pump and use it in conjunction with HOM! If your meth pump ever fails, the failsafe built into the HOM feature will keep your motor safe!

Is Trifecta Stage 3 available for my car?
This list shows all GM Stage 3-capable vehicles (excluding the Ariel Atom), along with their current supported status through Trifecta:

• 2007 Cobalt SS Supercharged: Trifecta + HP Tuners *
• 2006 Cobalt SS Supercharged: Trifecta + HP Tuners
• 2005 Cobalt SS Supercharged: Trifecta + HP Tuners
• 2007 Ion Redline: Trifecta + HP Tuners**
• 2006 Ion Redline: Trifecta + HP Tuners
• 2005 Ion Redline: Not Supported
• 2004 Ion Redline: Not Supported

ARIEL ATOM STAGE 3 IS FULLY SUPPORTED BY TRIFECTA, BUT NOT LISTED BECAUSE THEY DO NOT HAVE/NEED A/C

If you own a GM Stage 3 module for any of the unsupported vehicles in the above list, please contact trifectaperformance@gmofhouston.com for details on how YOU can help get that make/model year supported.

*Requires a special HP Tuners beta in order to access this model/year. I can provide this file, or you can email support@hptuners.com with “Request for Beta” in the subject line, and your HP Tuners serial in the body to acquire the very latest beta.

**HP Tuners support is dependent on the HP Tuners support staff taking the time to make a profile for this and adding it into a beta. The tune is available as HPT-compatible, but not necessarily supported. That is up to the guys @ HP Tuners.

Alright, I’m convinced, where do I sign up!?
If your car is among the list of Trifecta supported vehicles and you are interested in the Trifecta base or a Trifecta custom tune, you can ask your local Trifecta dealer for more information. A list of dealers can be found here:

Trifecta Performance Custom Tuning :: Dealers, Independent Tuners and Affiliates

If your car is among the list of HP Tuners supported vehicles and you want an *.hpt file sent to you, you can email trifectaperformance@gmofhouston.com with “Trifecta Stage 3” in the subject line, HP Tuners infolog attached, and at least your Name and City/State/Zip in the body.

Thanks!!

edit:

Cliff's Notes:

• You dont need to buy a PCM.
• You can put this tune on your stock PCM.
• If you dont want a Trifecta tune, you dont have to get one.
• You can just get the GM Stage 3 tune with A/C unlocked.
• You can tune on top of this with HP Tuners.
• Its cheaper to get the non-HP Tuners version.
• You CANT tune the HOM or Nitrous with HP Tuners. Only through Trifecta. This doesn't mean you have to get a full tune. You can ask for just those parameters and still use HP Tuners for the rest.
• You can buy this through any Trifecta dealer.
• For the HP Tuners version: You can have a Trifecta dealer flash the HP Tuners version to your car, then YOU extract it and copy your tuning parameters to it with HP Tuners
• You can get the HP Tuners file directly through me via email if you have 2 credits or your entire model year licensed.
• You can also send me your PCM to avoid spending any hp tuners credits.
