#38795
Did you find the reason of the wrong voltage reading ?

And Dvjcodec, about the 10k pull-down resistors on each signal of 4504, did you update you schematic ? Cause I can already see a pull-down resistor on each mosfet, like R3 for Injector 1.
#39224
Finaly I finished fixed pcb for this ECU.
Fixes and updates:
- add 10K pull-down resistors
- Teensy 3.5 internal pad footprint fixed
- add solder-jumper to choose internal or external Map Sensor

Have you tested the stepper motor?
it does not work on my board.
Please try to add 3v3 supply to ENAble

I have tried it, and the same result, there is a problem with the board. The stepper motor driver does not have 12V power at all. I gave the driver 12V power by jumper, but still can't work. I gave up

Yes, I a problem with board. Missing +12V connected to this point. Bug in schematic :/
