ok, when ever i datalog my del sol with all good equipment like dist, motor, plugs etc. I never have any problems. but when i tune my friends car obd0 civic b16, I get all messed up rpm readings. (20000 - 80000 rpm). I dont know what the hell that is going on. Ive seen this before on other people cars, not sure if it is the car or my wideband. Any answers would be helpfull.

 

oh ya, i have used diff signal wires aswell to see if they are diff, but they all ack the same. ive tried injector, dist for a diff rpm signals
