I had someone putting an arduino based signal simulator for me to "run" my SQ6M so I can  verify  things like external shift lamps, old Analog tach etc. without running the engine.
That project is stalled.
Any reason I can not use this ?


I am already using a 60-2 magnetic crank trigger in the car so I thought I could hook this right up.

While it just has a twist knob, all i want to do is compare the SQ6 RPM on my laptop to the operation of the tach and shift lamps.

Thanks for any input.

Hi 95wagon,

As long as you cam and crank setup of your ECU matches what that unit outputs it shouldn't be a problem. Reading the link it looks like a standard N-M 60-2 setup so you can use the N-M setup in the ECU as well so should be fairly straight forward for you to setup.

Ok, both the Electromotive , and the Arduino based crank  simulators work perfectly , to run up the  ECU .

If any one is doing this, the  trigger type setting must match the simulator.
Electromotve   Mag
Arduino           Hall.

This all leads me to a new question.
The car was running fine before disassembly  for mech maintenance

I don't believe I have a real problem, just something that happens when testing with components not connected.

I first started with nothing but a crank signal.
Tach out put , all perfect 0- 8500

I started  studying live data in the Caltool.
At about  1550-1600 rpm and above   , the A_ign_total will go to -90
I started hanging stuff back on
OIL Temp
Air Temp
I never put the injectors or coils as I do not want to run either dry, or not completely assembled.
charge-a-load sits at 0 ms
dwell_limit sits at False
max-T-charge is RED  at 7.00 ms
t_charge is RED at  5.43 ms.

As I said, I don't think I have a functional problem, just trying to understand this.

Thanks for any direction.

EDIT !!!!
Oil pressure cut speed is set at 1500 so that is likely what is going on as I have no oil pressure because the engine isn't really running 🙂

Exactly correct with oil cut..  -90 means that an ignition has a cut applied... you can check and/or change your limiter properties in Software Setup\Torque Reduction\Torque Reduction Mode by Source..
