I installed the TRACS system into my 850 from another vehicle. I changed the ABS modulator and the ECU and connected the TRACS switch on the wiring that was already in my car. When I start the car the lights for ABS and TRACS go on, and after a few seconds they go off at the same time. The ABS seems to work fine (I can feel it work during braking on wet surfaces). The OBD does not report any errors. But when I turn on the TRACS system and accelerate sharply on wet surface, I do not feel any differnece. The wheels just spin just as they did before without TRACS. How do I know if the system really works or is TRACS just so lousy that I don't feel any difference.

Thanks for any suggestions
