HEAT PERFORMANCE Transmission Control Module
Upgraded Transmission Control Module for most 5.7 and 6.1 lx cars

Heat Performance is now offering an upgraded TCM for most v8 platform lx cars. It must be installed at the dealer as it must be flashed through a star scan and connected to Daimler.

This is a simple modification that will allow the car to have a positive shift as opposed to the hesitation, or pause before shifting. The module is similar and designed from the AMG Mercedes sport tune. The stall rpm is allowed to reach approx 400 rpm higher. This is done electrically. There is a mechanical stall; however there is also electronic control over it. It will make your vehicle much more natural.

GS Motorsports LX Model Intake System
SKU: GSMLXINT
GSM Ram Air Intake is designed to pull much colder air than the typical big filter mounted in the engine bay, we have also re-located the IAT to a much colder area resulting in a very effective cold air kit for the LX Platform cars with 5.7 & 6.1 engines

GS Motorsports 6.1 SRT Performance Calibrated TCM (transmission control module)
SKU: GS61TCM

· GSM 6.1 SRT Performance Calibrated TCM (transmission control module)
-GSM has completed a performance Transmission calibration that gives the following enhancements over the stock calibration.
· Torque converter stall raised 500 rpms,
-This gets allows the car to move much quicker in to the rpms and higher torque curve resulting in quicker acceleration.
· Holds the gear longer,
-While in D the stock car will shift early and with our calibration the car holds the performance gear longer before shifting to a cruising gear or the next gear .
· Increased line pressure
-This provides quicker and firmer shifts and very exact shifting when you are under hard acceleration
· General Information
· This module is a direct replacement factory part and we provide complete factory instructions.
· This unit must be installed at your dealer as the can bus system requires that you
· Have a scan tool to input the serial # to link the new module with you vehicle
· Currently this is only available for the 6.1 300, Charger and Magnum SRT’s

Jet Stage 1 and Stage 2 Performance Chips for SRT-8 Grand Cherokee
#90420 Module:
#90709 Module: (Note: This is what you need)
2006 Jeep Grand Cherokee SRT-8 Hemi Auto-Stick Tranny

The ECM in the vehicle looks at various sensors such as manifold vacuum, coolant temperature, throttle position and RPM, it then processes this information and adjusts spark timing, air/fuel ratio and other parameter according to the tables stored in the JET Performance chip/module memory. By recalibrating these tables Jet Performance Products is able to tune the engine for the maximum horsepower and torque under various driving conditions.

By installing the JET module, these extra increases in performance enhance drivability, towing capabilities, reduce 1/4 miles times and provide improved overall efficiency.

STAGE 1:
If you have a stock engine with no other modification, this is the chip for you. The JET Stage 1 performance Chip is programmed for maximum power increases on a stock vehicle for improved performance under hard throttle conditions such as towing and wide open throttle acceleration.
*Special Note: Stage 1 Chips are street legal in all 50 states. *CARB EO#D-234-4
STAGE 2:
Designed for modified vehicles with low restriction exhaust and modified air intakes. The JET Stage 2 Performance Chip has been calibrated for peak horsepower in cases where the engine has been modified to run cooler and the exhaust system is less restrictive than original equipment. *Special Note: Stage II Chips are street legal in all 50 states. *CARB E0#D-234-4

Note: Not sure which Jet module to choose? Confused? Jet gives a weird listing for this particular part. According to Jet, this part was, if anything, accidentally listed twice and given two different part numbers. Both part numbers are actually the same part and work on ALL SRT-8 Grand Cherokees. To simplify things, Jet specifically recommends ordering the 90709 module for your SRT-8. The 90420 still awaits release.

Is the TCM for the 6.1 compatable with the B&G Stage II flash?....will this upgrade cause hard, tire chirping shifts like the shift kits of old?

In its original shiiped set up no... But if that is what you want we can program it to do so.

Why would I not want it programed to shift hard?...and are you saying it is compatable with B&G flash?

Shortly has come and gone...
It is indeed compatible, and partner it with Heats 2500 stall converter and you'll have a ~2800 stall and ~3000 flash...should RAWK :rockon:
I have all of the above going into my build.

My trans does not hesitate when shifting..just shifts soft...so soft I am not aware it has shifted most times...now my Ram SRT10..4sp auto and I have no doubt when it shifts..especially 1-2...even mild acceleration can give a chirp during 1-2...WOT and depending on the pavement the rear may go sideways...good ol' days shift kit shifting...

If this mod will make my SRT8 do the above I will buy today...but I want a guarantee...if I am not satisfied I can return...I say this because 2 mods I have purchased said this would happen..only reason I am not fussing is the other claims by the mods did better than expected..

B&G flash and GSM/ESP mod....the B&G has made a big diff in the car...not just I feel..only problem is launching because it has made the tire spin worse..(or good..dang)..the only good I see the GSM/ESP mod does for the SRT is the fan control..I do recommend for the RT...

i get this in my dads srt10, sometimes if you work it just right you can make it chirp in 3rd....but my moms srt-6 dont chirp for ****...i duno if that manumatic shifter is all its cracked up to b....that truck is a beast!(i liked the commemorative edition w/the 6 sp he had last yr better tho...

B&G stage ?, sorry i don't remember.
I agree on the GSM fan/tm/esp...
I saw you just bought some new rubber for outback...that will help some...I will be posting some info and pics of my DR set up tomorrow, they will surely keep you well in tact with the pavement.

Did the Stage II flash..the car is more responsive and ran .182 second faster afterward using same launch procedures..only diff was about 5 degrees lower temp...

I read the information in the service manual and started thinking about some of the mods in circulation. Seems like the T-stat mod would keep the engine under many circumstances from reaching operating temperature and thus relegate control to the tables in the PCM. Notice the last line. The objective of the PCM tune is to tune the vehicle for optimum fuel and emissions performance. Here is the quote from the manual:

"The PCM will operate in two different modes: Open Loop and Closed Loop.

During Open Loop modes, the PCM receives input signals and responds only
according to preset PCM programming. Input from the oxygen (O2S) sensors
is not monitored during open loop modes.

During Closed Loop modes, the PCM will monitor the oxygen (O2S) sensors input.
This input indicates to the PCM whether or not the calculated injector pulse
width results in the ideal air-fuel ratio. This ratio is 14.7 parts air-to-1
part fule. By monitoring the exhaust oxygen content through the O2S sensor,
the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance."

So, whats all this mean? You aren't benefiting from am thermo mod?

Looks like the PCM code isn't as interested in ideal fuel and emissions control until the car reaches operating temp. The T-stat mod would keep the car in many circumstances from reaching OT, so performance would be better. At least that is what it seems like. I wonder how tuners work? Do they turn off the OT (closed loop) part of PCM operation and then run constantly on their own modified fuel, air, and timing tables?
