hey guys. i set up my VAFC and did the 10-second on, 10-second off throttle calibration when the car was off. sensor check indicates i have somewhere aroudn ~.45 volts closed, and 4.6V at WOT. however when I start my car, my closed goes down to ~.25 volts. i'm assuming this is because i have a different throttle body. however because of this, the calibration is off and it think i'm stillat 0% throttle when i'm lightly pressing the pedal. it does get annoying because the throttle reading is off now. is there any way i can calibrate it to the right setting while the car is on? i wouldn't really want to try holding it at WOT for 10 seconds when it's on, though

shouldn't the reading stay the same when the car is started? Why would the tps voltage change?

 

word

 

beats me. but it does.

 

Usually the values increase with the car running because the alternator is charging. So if I were you I would check output voltage on the alternator, just to make sure. Then I would check the wiring for the vacf.
