Default spark control?

Anyone seen off hand if there is any spark control that will increase or decrease spark timing depending on how hard you blip the throttle and or other variables?
talking like how AE adds more fuel depending on how hard you get on the throttle.

I'm not sure why this facility would ever be needed, care to explain your thinking behind needing it?

If you had an MSI or MSII, you could probably write a few lines of code that could increase the timing X amount during any accell enrichments.


but why?

rapid throttle opening or closing, changing location on the spark map that needs to compenstate due to varying loading.

Like going from high boost high rpm to letting off the gas ( low kpa high rpm) quickly back into high kpa high rpm

oem's have had this feature in their ecu's for a long time

your spark map is load vs rpm. it reacts very quickly to any change to load.

Well pretty much instantaneous as it's electricity. You need AE for fuel as there's an element of lag involved.

so you want spark to be, say, retarded 5 degrees if you step on the throttle faster than normal for a brief period?

configurable
but example is drop spark out at a settable parameter like 5 or 10 degrees based on tps or settable parametter for this many ( settable ) engine cycles and return linearly to spark on timing map
