Building ms1 v2.2 no tps signal passes but troubleshooting

Post by erikfromgilroy »

I'm having a dilemma of whether to move on to the output section or not because I'm testing my ms1 on megatune but the tps isn't working. How do I know if it's the stimulator or my ms1 before moving on.

Could this be moved to the Boards forum. It's get some more traction there. I'm new here and eager to get this thing finished before I start the motor swap

Check the voltage to ground with a DVM at the TPS input pin on the DB37. It should vary as you alter the stim pot.

BTW, best to use TunerStudio these days.

New update. I did some stuff for Edis to work on my ms1 and now it won’t connect to tunerstudio. I did exactly the hardware mods listed on DIYAutoTune ms 1 v2.2 board and now no connection.
