I've purchased a MS3PNP recently and I'm installing a VTPS for my miata I've jumped the Tps on the megasquirt but when i try to get throttle calibration its really weird and either stays at a certain amount and does not let it go all the way up. I've attached videos if there anything else I can provide to make this eaiser im new so im not sure this VTPS is from speedyefi. In one of the videos i messed around with the numbers on the calibration to see how to get 0% and 100% throttle.

 

The scale is random, not important, as long as throttle reads 0-100% smoothly, that’s all that is important. Most “0-5v” sensors like map, tps, oil/fuel pressure, etc actually operate in a .5-4.5volt range, so you’ll never max out at 5v.

 

the thing is with mine when I put it on it only shows from like 23% to 63% around those two values so I just took a little time to see what values in the calibrations would make it give 0-100% on throttle but as the video shows the blue bar only goes so much so I’m not sure if that’s a issue or if I’m fine putting numbers in that tell it that it’s closed and full throttle

 

? There’s a button you press when you’re at closed throttle, and a button you press when you’re full throttle. You don’t have to enter numbers.

 

yeah the thing is when I do that and click the button supposedly my full throttle is only 63% and my closed throttle is 23% so that’s why I’m wondering if it’s like a issue with the tps or wiring

 

I guess I don’t understand, because in both your videos, you’re going 0-100%. The ADV/mV values where 0% and 100% exist do not matter what so ever.

If you calibrate it and it eventually drifts, that’s another issue.

 

hey sorry for the late reply but I got it working all good now on to fix this idle issue I have
