Hey all,

I am having a super hard time setting base timing in megasquirt. I set fixed advance to fixed timing and timing for fixed advance to 10 degrees. I set trigger angle to -17 and timing light showed the timing was 0 degrees on the ati damper. Changed trigger angle to -25 and still no change in timing, still showing 0 degrees. I e changed trigger angle from -17 to -60 and all those angles have still come to the timing light showing 0 degrees. I’ve done a composite log and everything came up fine. I am literally at a loss I have no clue what is going on. Here are some specs of my build and some other settings I have set to in ignition options/wheel decoder:

1996
bp4w swap
ms3pnp pro
all NB sensors
wasted spark
Ignition input capture: falling edge
Spark output: going high

should be it. I appreciate any help!

 

Why on earth is the trigger angle negative 17?

 

That would be retarding 17 degrees, right?
Output test mode to ensure spark is firing when it should, batch injection/wasted spark
Use 99-05 trigger wheel input for your NB sensors not 4g63 or miata 36-2


@Morgan Hunt you can post up your .msq file (your tune)


Also start a build thread so we can see what you're doing from the start. We like Pictures

 

Updates?

 

because he'll never update this...his trigger wheel was installed backwards.
