Adjusting Throttle Position Sensor with PFC

How do you use the switch/sensor screen on the PFC to adjust the TPS? What is the correct range?

Yes, viewing the info on the commander. The PFC shows that info, I just need to know if the "v" range is different from the stock ECU.

I love how easy the PFC makes it to adjust the TPS, just bring it over to your engine bay and goto town with it.

Are you certain? I was told by someone else that it was the other way around...

^^^ Someone else is wrong

VTA1 is the FULL RANGE
VTA2 is the NARROW RANGE

That is on the sensor check instruction page of the commander manual. Plus i jusst did this the other day and let me tell you. As a technician, I am almost willing to force everyone to buy a PFC JUST for the troubleshooting ease, I just found a bad OMP on mine with the same sensor check page. Car started running like junk, checked the screen and the OMP is highlighted. Test the OMP for resistence, and it failed the test miserably. But it took me 5 minutes start to finish to diagnos.

very cool!

OMP = oil metering pump? I didn't know it gave an electrical signal. I thought it was mechanical.

IIRC, doesn't the OE ECU throw a CEL if the OMG signal is off?

the 2nd gen has a mechanical OMP from 86-88. From 89 to 91 is was electrical in that is saw a given voltage and squirted in oil based on the voltage it saw. The FD is the same way. Depending on load and rpm, the OMP voltage will vary as will the oil being squirted in.
