So after installing my new motor and getting it tuned im coming across noise in the tps, map and clt sensors. tps is the wost of the bunch. i dont think it was a problem before but it is now. Iv got a 1710 box and i think its rev c i forget.

Any tips on reducing the noise? at closed throttle tps fluctuates very fast from .7% to about 1.5% is this normal?

Iv verified its not a bad tps with another unit and iv checked the ground at the tb and the ppf they are clean and good.

I hacked a bunch of AEM series 1 boxes to reduce the noise in all the analog inputs.

You can get by without the hack... just make sure the TPS reading never goes to zero.

yeah i have adjusted the tps voltage settings so it always reads >0% and <100%

any info on the hacks?

Hacks are pretty invovled. I've documented them so that I can repeat them, but not in a manner that someone else could do them.

Here's one set of data showing improvement
