anybody know how they are measured on the f4i's i believe all f4i's are the same, with the cluster and wirering harness. im guessing there is a senser somewhere near the flywheel? idk honestly, anybody have a clue? reason for asking is my tac is doing some pretty crazy stuff ha ha ive searched the forums for this subject, and also trouble with the tac and cant find anything

 

well looks like the tac, comes out of the cluster yellow and green wire, through one conector, and then into the ecu and pretty much nowhere after that, lol now i really dont know were to start ha ha
