I've started a build on my minitruck project (1991 triton) with a speeduino 0.4.4c surface mount board.
I'm a little confused as to which 5v pin and which ground pin to use that correlates to the 1k pull-up resistor when you jump jp4. Or does it not matter?
I'm using a zf cherry hall and want to make sure I get these right before trying to start the car.
Right now I'm using.....
Pin 23 as hall ground
Pin 25 as hall signal
Pin 28 as hall 5v (VCC)
In some of my testing to see if I had a signal, it appeared ok just cranking and checking with a timing light.
But when I did a short tooth logger I got a strange result like the sensor missed a tooth when it shouldn't have. (Theoretically causing a spark to early)
If I try to start the car like this I'm sure it will backfire, as I'm running LPG it's a vapour fuel and can happen really easily. I don't want this to happen.
I'll try and upload a picture of the log. Green is the signal I should be seeing with my 36-1 wheel, red is the extra one that shouldn't be there
