I've nearly completed the build of my MS2E for a '00 with stock sensors.
All is working fine except that I can't get an rpm reading with the jimstim.
I'm using Abe's input circuits (on pin 24 and 25)
On the Jimstim, everything looks ok:
- dips are set for miata: 2,3,6 are on, others are off
- connected a jumper from 2nd trigger to pin 25 (IAC1A)
- primary tach jumper is in the bottom location, no other jumpers next to it
Basically like this:
On the MS I wired the 2nd trigger input to be fed from the IAC1A terminal (pin 25 of the DB37). I have continuity between Jimstim 2nd trigger pin and the input of Abe's circuit.
I can only assume this must be a software setting ?
I selected miata 99-00, falling edge, spark output going low, wasted spark, D14.
Anything else I need to set?
