No TPS + Stock ECU?
I have an emissions test looming in the next week and ive put it back to the stock ecu, AFM, purge solenoid, open wastegate, blocked Bov. Took it out for a spin and seemed really gutless. Would having no tps cause this and is it a concern for my emmissions test?
btw, i was sort of impressed at the stock ECU's ability to keep a stoich mixture all the time.

TPS = Throttle Position Sensor. An analog (potentiometer) device which outputs a voltage which varies with throttle setting. Found in all '94+ Miatae, as well as '90-'93 cars with an automatic transmissions.
Confusingly however,
TPS also = Throttle Position Switch. A simple device consisting of two switches, yielding a total of three positions:
1- Throttle is completely closed. (fuel cutoff and idle)
2- Throttle is completely open (WOT)
3- Throttle is somewhere between closed and open (everything else)
Found on '90-'93 cars with manual transmissions.
