would have 2 inputs, wheel speed and gearbox speed, the holley dominator ecu setup to read these 2 inputs and when there different, ecu knows theres some wheel slip and retards the timing or drive by wire throttle inputs to stop slip - ie a traction control system

Finnegan of roadkill showed where he had a speed sensor attached to his driveline and then attached to his Holley Dominator for potential traction control. I have not looked further, but the sensor he had on the driveline looked pretty simple to install. Can't remember what show it was on (not roadkill or FMS). But the vehicle was Blasphemi and can probably be found on Motortrend somewhere. Maybe not a ton of help, but it can be done.

Believe it or not I had a similar problem with my 8,000 mile, '85 Corvette and it's 10 year old, original Goodyear Gatorback tires. A new set of tires (Goodyear GS-D3's at the time) and problem was fixed... for the most part. 
Good luck, it sounds like a fun project.

I have not put them on a corvette wheel. But have on a number of Harley Davidson applications. Mostly to convert older bikes to run a electric speedo. A simple hall effect sensor will count most anything. The electric speedo l have been running on my C-3 for over 10 years runs a Harley pickup mounted to a steel strap held onto the tail of my gearbox with hoseclamps. Counts the u joint holder part of the yoke. A hall effect sensor will count most anything magnetic. Good luck

iam having major traction issues, half throttle inputs, 4000rpm max revs, still leads to major wheel spin in 1st, 2nd and 3rd gear, still on the run in period for engine
would have 2 inputs, wheel speed and gearbox speed, the holley dominator ecu setup to read these 2 inputs and when there different, ecu knows theres some wheel slip and retards the timing or drive by wire throttle inputs to stop slip - ie a traction control system

You have to first upgrade your ECU to v5.
If you get the drive shaft sensor you can apparently setup your own "poor-man's traction control" using free capabilities in the Dominator ECU, too: https://forums.holley.com/showthread...action-Control

Then I think you're stuck with this: https://forums.holley.com/showthread...action-Control
Front and rear-wheel speed sensors, compare the diff between the two and plot it in a 2-dimensional table that pulls out more timing as the difference between the two gets bigger. (Free, though...)
