MS3 Basic 6000 rpm backfire and check engine light
#61
Gents,
Just had my first chance to drive her with the new sensor after turning Noise Filtering back on. The drop off and CEL is back, but this time at about 6400 rpm.
Are there any negatives to turning Noise Filtering off and keeping it off? I'll probably try a larger gap first, but this really has me shaking my head.

Had feeling this problem wasn't fixed.

Any speculation as to what might have happened? As I had mentioned, the tuner thought it was something he'd done, and loaded the previous tune. The problem remained, so we both thought hardware. The new Mazda sensor fixed the problem, but only by turning off Noise Filtering. The new CARQUEST sensor did not fix the problem, even with NF off.
Thanks for your time,

Like I said sensor too close to wheel probably caused the aftermarket sensor to not work at high RPMs. Mazda's sensor is more robust in this regard. Thus why i said test it while you had that sensor to verify if that was the issue.
Regarding noise filtering the noise filtering settings are wrong if enabling the filtering causes a loss of sync. Either figure out how to set them correctly (Good luck, I tried searching when you posted this thread and got nowhere) or just don't run it. I don't run noise filtering either as Scott says.
