Help!!
 

I recently installed a Dynotune Nitrous kit. I had a gm mechanic do the install. The Dynotune TPS switch does not learn my car. Is there a different switch out there you guys out there recommend? I have a 2005 cobalt SS

I used an NXExpress TPS switch and it works fine on my '06 look in my gallery for
pics

did your mechanic open your throttle body by hand or press on the accel 7 times?

No nothing quite like that, I did the install myself, I got the wiring diagram for the
throttle harness from alldata diy and found the proper lead, the nxexpress tps is self
learning, when you have it connected right is shows a sequence of flasing lights to
indicate it's right

thats almost the same as mine, you connect the wire to the tps and then turn the car off and on 3 times to get the NMU in learning mode, then you have to hand operate the TB blade or press the accel, i think it was 7 times. And then the light would turn green and you were all set.
