Memory Trac and ESP Module
Memory Trac and ESP Module
I am in the testing stages of the new Memory Trac and ESP Module. This module will change the behavior of the traction control switch so that all model years operate in the same manner that the 2004 models do that pressing the UP side of the traction control switch will only disable the traction control and likewise the Down side of the traction control switch will only enable the traction control. This can be seen in the beginning of the video below. This module also has a built in memory that will return the traction control to the same state it was in previously before being shut off. If the traction control was disabled, when you start the car, it will automatically turn off. If it was enabled, it will remain on. It also features a selectable negative output that can be used to the ESP. The procedure for this was developed by Woody and can be found HERE. The Memory Trac and ESP Module handles this with a negative output on the module that can control a relay instead of a rocker switch. This allows the entire installation to be hidden beneath the center console and without drilling any holes for switches to retain a clean and factory look. To enable this negative output, you must hold the UP side of the switch for approximately 10 seconds and wait for a tone at which point the negative output is activated. This output will stay activated until either the vehicle is turned off or the DOWN side of the traction control button is pressed. The negative output will NOT activate again at startup regardless of the last state it was in when the vehicle was turned off and you must press and hold the UP side until you hear the tone each and every time you want to activate the negative output.
Here is a brief demonstration video.

another cool toy would be for tuning inside braking to act like cutting brakes.

As far as the torque transfer, you'd have to have traction control enabled for this to work and at that point the all benefits are negated.

Re: Memory Trac and ESP Module
just throwing out ideas, but I don't mind the TC works great in my o4, but I would like to play around with reducing wheel spin, be it under throttle around corners when TC is off. but you probably have to interface with the steering angle sensor and who knows what else?
Re: Memory Trac and ESP Module
Hey Rudy, so what does holding the button down for 10 seconds actually do? Does it functionally disconnect the yaw sensor? With it off and the TC off, does that mean we can finally do powerslides and proper donuts? Is the Crossfire ready for drift competitions now?

Also, due to the nature of this product, everyone that buys one will be required to sign a waiver and accept any and all liabilty for anything that happens as direct or indirect use or misuse that occurs regardless of who is operating the vehicle. Not trying to scare anyone but this module has the potential to be used to disable the safety systems built into the car by the manufacturer.

Re: Memory Trac and ESP Module
Rudy, a couple of questions:
I have a 2004. Can you tell me what I have that newer years do not? Also I have a question about the rear end. I just got through watching some Crossfire burnout vids on you tube and many off them have smoke billowing out of both wheel wheels and some are only burning the right tire. I thought we had open rear ends?

Re: Memory Trac and ESP Module
even with the TC off, the car will over ride and kick on if the wheels spin pass 30 mph. With Rudy's mod, it will not over ride...therefore, Rudy, will I only spin one wheel? Will I have to upgrade my rear end to limited slip? Which I am going to do this winter anyway...just curious. I want this mod...

Re: Memory Trac and ESP Module
I aware of the way to shut them off, but having a switch in the car where the switch is for the wing in non SRT cars is a clean look. I could wire in a cut off switch to the fuse box but just really not interested in doing that...so, Rudy, if I over ride the system, I would assume I will need the limited slip rear end...

As for what it does in reards to the 2004's is how the switch operates. In the 2004's, the top part of the switch only disables the TC and the bottom only enables it. This module will make the 2005's and newer behave the same way.
As far as tires go, the guys that are spinning both of them just got em good and hot and both broke loose. It's just an open diff back there so you'd need to do a phantom grip to lock them both together.
Lastly, this uses the traction control button, not the blank in the SRT's where the wing button goes on the base/limiteds. I have that used for the intercooler pump/radiator fan module that turns them both on high, even when the car is on but not running. Useful for when you're hot lappin it at the track.
