when the tps sensor is plugged in the car detonates in 4th and 5th gear, when i leave the car running and unplug the sensor then plug it back in the check engine light comes on but the car doesnt detonate, although it makes no power. the tps was calibrated using a crome pro unit not the hondata unit the car runs on(no tuners in area). any ideas of what could be causing this. btw i just replaced the tps sensor trying to eliminate problems. any ideas would be greatly appreciated

Detonation has to do with timing, or anything else that effects burnrate. You probably have a bad tune.

 

lol. 4 years old, 38000 miles, 483whp 19psi and pump gas=bad tune.

 

Maybe over 4 years and 38000 miles something changed.

 

tunes dont change, something has to be wrong to throw off the tune....

something is obviously wrong if you are getting audible detonation. If you think the tps sensor reads incorrectly or something then check the voltage on it with a multimeter. Maybe you changed something with your setup, got a bad tank of gas, didn't have your iat adjustment setup properly for this weather, etc. I would look into getting another tune.
