Sharing my current progress on a rear launch control/max acceleration strategy for the 'Cuda.

I have a VR output shaft speed sensor that has proven to be accurate on my T56 Magnum. This will serve as my driven-wheel speed sensor. In order to have a proper street car traction control, I need an undriven-wheel speed sensor.

Up front I am using the internal section of the rotor cooling vanes as my pickup [32t/rev]. I have talked to two other Megasquirt users that have done this successfully, we shall see how it works. The sensor is a $25 Cherry brand off of Amazon and is a nice stubby all-thread for very good range of adjustment.

I have fed shielded 3-wire cable through the firewall for the VR and Hall Effect in an attempt to mitigate interference.

Hopefully this week I will button up the front sensor wiring and generate a signal. After that I should be off to tuning the traction control. This will complement what I have setup already for launch control and flat-shift.

My goal is to mimic some of how this car in the video operates. Managing a %slip from front to rear via pulling timing to provide the fastest acceleration. It will compensate as much as it can for tire grip and surfaces to keep the car moving forward.
