Engine had tendency to stumble at low rev so tried to mess with the TPS with TuneEcu.
Adjust ISCV mode
>adjusted step 1 to .6 V
>adjusted step 2 to .72 V
>after 15 sec TPS voltage comes back to .70 V and not to .6 V
the rpm hangs around 2500 rpm and takes 10-15 sec to come back to 800 rpm.
Also ,I had loosened the secondary TPS adjusting screw.how do I set secondary TPS through Tune Ecu

when I monitor throttle sensor voltage.Does both voltage need to match exactly
sesnor1:0.70V
sensor 2:0.73 V
 
PM warp9.9 on this site or the other one,
he's somewhere around here,
and he can help ya I guarantee it.
he led me through it and I was a complete novice.
9still am) but he got me going over the phone...

in step two you click ISCV reset and it moves the stepper motor out opening the throttles and then you should see .12 volta change in your TPS reading/ In other workds you set the TPS at .6 then click ISCV the ecu moves the ,motor outward opening the throttle and you see .72 on the new TPS reading if not you adjust the stepper motor arm until the TPS reads .72 is this how you did it? Or did you adjust the tps to read .72 by loosening it and moving it?
