Hi guys i want to change the software control system on my current dts 2wd dyno as electronics /software are starting to fail and its impossible to get any repaired etc its a telma vd1000108 retarder 24.5 ohms resistance measured at pwr supply wires ive attached a picture of the pwr supply box etc and speed sensor looks to be a 3 wire hall effect sensor just looking for input as to what i might need and any possible problems i might encounter also does the software control the retarder in.closed loop and steady state?
