Hi,

I would recommend getting the idle stable first so that the engine speed is consistent before changing this. The diagnostic is quite likely coming from the Engine Speed variations. What is the battery voltage like? if this is not stable the diagnostic can also be triggered.

The Dwell curves for the M1 are relatively conservative in their numbers, most of the coils could be pushed harder if needed, but with the associated increased risk of failure if treated this way.

Hi,

I have looked through your Package and there are a number of issues with it.

The Engine Efficiency and Ignition Timing Main tables were only configured to 3600rpm and the values in them were much lower than would be expected.

The Inlet Manifold Pressure Estimate Main table was all messed up and would have caused issues if the M1 reverted to it. This table is also used in transient response conditions, so if it is incorrect then the transient responses are not going to be as good as they should be.

I have lowered the Hysteresis values for the Engine Speed Pin.
