As a part of the Blue Angel Drive train upgrade, I am considering incorporating Traction Control (TCS). With the 700hp plus BB engine and and the TKO 600 tranny, I might need a little help. The Holley Dominator EFI has the PWM inputs to monitor wheel spin sensors, but that is about the extent of my knowledge. Anyone have any experience setting up a C3 drive train with wheel spin sensor capability?
Pardon my confusion, but I would expect the wheel speed inputs to be frequency inputs, not PWM inputs. All my experience with wheel speed sensors has been with variable reluctance types, which require some signal conditioning for the CPU to read the sensor signal frequency (and deal with the varying voltage).
About the only thing I can think of on a C3 that would be remotely similar in design for wheel speed sensing would be the brake rotor interior cooling fins. However, that's not very conducive to being able to easily position a sensor. (Edit: Missed Gene's comment about the magnetic field extender. Never tried that, but theory says it should work. Definitely a thinking out of the box idea. Good job Gene.)
The speedo sensor isn't a wheel sensor, although it should give a reading of the average of the two rear wheels.
