Re-purposing injector pins on DB37 MS2/Extra 3.57 PCB P&H

Postby jsdevel » Tue Dec 13, 2016 7:15 am

With the P&H v1.1b driver board and MS2/Extra on a 3.57 PCB, I'd like to re-purpose the original injector pins on the DB37. Is this possible? I'd like to use them for ADC or switch input.

Also, is it possible to remove a few of the MOSFETS on the 3.57 PCB with sequential?

Check the V3.57 schematics in the msextra manual. You could remove all the components for the injector drivers and that's a lot of components. Pin 2 of Q1 and Q5 connect to the DB37 pins as you can also see on the schematics and you don't need Q1 and Q5. But you can only use 2 I/O because the DB37 pairs (pins 32-33 and 34-35) cannot be "unpaired".
