t2 tps issues and microtech
I am having trouble with the rx7 tps in microtech. I do a tps calibration and the car is put into the idle map and the car runs fine. Once i start driving the car and i come to a stop/idle again the tps is out of calibaration. Basically i am not in my idle table anymore and the cars AFRS become rich so this i causing a real idle problem.
I am thinking of making a custom bracket for a full range haltech style tps but i was wondering if there is any better solutions? Is this a common issue with the microtech and tps sensors or am i looking to get a new sensor?
Thank you

So with the Microtech you can use the Haltech TPS sensor and retrofit it to the Microtech Harness?
I have a LT10S by the way
Also does that mean i can use this throttle body?

You can run any TPS you want with the Microtech. A Mazda unit, an on/off switch, a full range, etc. Doesn't matter.
Though I suspect the original poster is dealing with a throttle sticking issue, either caused by age or the cold start cam holding the throttle open.
The Microtech by default only uses the TPS to tell when the engine is supposed to be at idle, and to activate flood clear.

I am ordering a ford tps this week and fabricating the bracket. I am mapping the engine in MAP mode not by tps. The tps not showing idle in microtech causes some poor running at idle and this is my solution.
The only reason i want to change the tps is because the oem one is too expensive and this is a cheaper alternative.
Thank you for the insight guys

The same way you calibrate any TPS on the Microtech. Go to the TPS screen and then adjust it until you get zero % and an astrisk. You can either adjust it in software, or physically move the TPS.

the OEM throttle position sensors are garbage, i have had this issue before when setting the throttle it will go out of range from cold to warm.
you'll be better off mounting a different type of TPS, just about any will work.
also be sure your 1k RPM map is very similar to your idle map, in fact you can tune the car without the TPS at all if you wish, i have done this also without any ill effects. i just setup the TPS with a positive correction and disregard it.
