Indirtwetrust, Sorry the tool belongs to the customer, government job. It looks like the car is accelerating to about 50 FPM. I don't know if the processor in the tool is able to sample the information fast enough and display it correctly in that short amount of time? Let's say that the Venc the is only 8 FPM according to the controller and I have changed the encoder, relay pilot board, MSU and ribbon cable. I have verified the feedback from the encoder is good with a scope. channels lead and follow each other correctly on a 12 volt scale. I recently swapped the MSU with another running car in the building and it ran another car in inspection with out fault. What am I missing? Do you have the info on adjusting the MSU pots?
