Rev Limiter switch to Spark cut?
How can I get the rev limiter to use spark cut instead of ETC or Fuel? Messed with the spark ratio and fuel cut ratio some and no luck. Set N rpm limit time 4k hits it and uses furk cut

Go to spark limit rpm x load . Change the last row to your expected limit rpm . Change the column to -20

Most Ford ECUs I've seen do not support just cutting ignition.
The only time I see them actually cut ignition is when they've cut fuel.
By default the ECU doesn't support this operation essentially.

That is not an ignition cut. That is just massive spark retard. Its still firing the spark.

I read something about setting torque hst. To 0 under the fuel cut section and it gives a fuel cut instead of a throttle closure. I never have gotten around to seeing what exactly it does.
