No 5v output for TPS
I have mspnp. I have no out of 5v from the ms at the connector. I checked the continuity on all three TPS wires from the ecu pins to the connector, and everything was fine. So is there something wrong with my mspnp, or is there something in the settings somewhere that needs to bee turned on to have the 5v output to the TPS?
I tried the calibrate the TPS and no matter what the throttle position is, the out was always 127 in Megatune.
So if anyone has ideas, any help would be greatly appreciated. Thank you in advance.

ehh, I had assumed that he was installing a linear TPS
with the stock setup, there are 2 resistors on the daughterboard that lock TPS at an artificial value, and there's no need to calibrate the tps at all.

FYI the procedure is covered in the MM9093 manual for how to change the unit to allow use of a linear TPS if you want to fit one. We can make the internal change as well if you'd prefer for a small fee. You can contact us at websales@diyautotune.com if you'd like to make that happen.
