Copperhead - Tip In Spark Retard

The way the logic is done in the Copperhead ECM for Tip In Spark Retard is a little different than earlier years, in fact there are differences between how the 11-12 Mustang handles it, compared to the 13-14.

In this screenshot, you can see how it is handled in the 11-12s.

If the Airmass/Event exceeds Airmass Enable, the PCM infers a tip in has taken place, and removes the amount of timing specified in the Spark Borderline Tip In Modifier vs. RPM

--------------------------------------------------------------------------

In the 13-14, there are a few more parameters.

Spark Tip In Borderline Retard vs. RPM vs. Load is how much timing is removed from the borderline spark calculation.

Spark Tip In Pedal Delta Enable vs. RPM vs. Load is the % pedal change to be considered a tip in.

Spark Tip In Load Delta Threshold Enable vs. RPM vs. Load is the load increase to be considered a tip in.

Spark Tip In Events vs. RPM is the number of spark events to keep the retard amount pulled.

Spark Tip In Events Delay vs. RPM is how many spark events to wait before removing the timing, once a tip in has taken place.

Is it safe to just zero these tables out and not have timing pulled in tip in? Is this considered a form of torque management?

Yes

Is that common to do (zero out the tables) on Fords?

Yes, pretty common tune change. In the older (EEC and Spanish Oak) PCMs, it was done another way as well, and it was common to just disable the logic.

wht is the difference in year model?

You can also work with the threshold points to control when the tip-in is signaled. With more aggressive combinations such as positive displacement blowers, it may be desirable to retain the tip-in retard but delay the trigger until heavier tip-in conditions are met. Working with the thresholds, you can tailor when the logic is activated. The thresholds are in terms mass per intake event.

If electronic throttle tip-in mgtm is disabled, would it also disabled the tip-in spark ? or do they work independently from each other ?

Seperately

Ty sir.

Nice tid-bit, the V6 for 2013 is set up like the earlier Mustang Eric posted. I was wondering if we should just 0 that table or use the Airmass Tables, good stuff and thanks guys...

Either way will eliminate it.

should i max out the value or put everything to zero to disable tip in spark management ?
