Hey guys I have used both a Wells TPS and a BMW TPS, but no matter what I do I can not get it to give a WOT reading.. I dunno if I am doing something wrong or what, but I'm so furious that I will pay someone anything to get it to work correctly.
I live in Northern VA so if anyone can help out please pm me so we can work something out.
U need to adjust it from the signal wire. Closed throlltle should be very close to one volt and wot shod be close to 5v
I am sorry for sounding so dumb, but what exactly do you mean? Like adjust the physical position of the sensor? I have it wired into the stock harness so I'm not quite sure what you mean by adjust the signal wire.
Ur not adjusting the signal wire, ur adjusting the tps. Ur using the signal wire to verify voltage at closed throttle and wot. Go to youtube and search adjust tps. Doesnt really matter what kinda car they r using the all adjust the same way.
I am using a MS3x. It has already been configured to accept a vtps
apparently it hasnt
you are both making this soooo much harder than it is.
go to tps setup in TS with the laptop connected to the MS, click the "set low threshold" (or something like that) button.
floor it, click the "set high threshold button"
That is the problem is that both the closed and open throttle numbers are the same so the vTPS is not reading the position of the throttle correctly.
The ECU does read a number from the vTPS it just won't change so the ECU is seeing something.

This is conjecture, and not necessarily true. If the tps wasnt even connected, TS will still display something, although your right it wont change, and that something is usually 0.
You have a wiring issue.
In either case, you dont need to adjust a thing on the tps, dont listen to freddy, he doesnt have a clue.
What year is the car? And how (specifically) did you wire the TPS into the stock harness?
i think this only applies to 1.6 (90-93), but heres how i wired mine:
wiring is color accurate to the wells tps and a 90 miata 1.6
this is with an ms3, not x, so your input pin is probably different, but everything else should be the same. again not sure if it applies to 1.8 as far as colors
Also make sure 5v is coming from the MS. If there isnt, check the small fuse on the board. If you wired the TPS backwards, itll short 5V supply to ground and blow the fuse.
