Decel enlean on $8D
Guys, I did a search on this but didn't get an answer.
How do these two tables work? What do increasing or decreasing values do to the fueling?
Decel Enlean FActor vs Delta MAP
Decel Enlean Term Multiplier vs coolant temp
I noticed my BLM's jump to 150 in the range where the Decel Enlean is activated. Playing around with the VE tables in that range has no effect.

Re: Decel enlean on $8D
Ok, so I e-mailed Tunercat. True to form, quick and informative response....
Seemed like the perfect thing to make a tuning tool out of, so I did...

See line item 6.
Basically, copy the three tables mentioned above into the tool and then find the decel enlean factor for a given coolant temp by clicking on the worksheet tabs.
Way this works is that the injector pulse width gets multiplied by the resulting DE factor.
The decel enlean factor is a multiplier that is applied to the calculated injector pulse width whenever decel enlean is active. There are three tables associated with the decel enlean factor:
T1 - Decel. Enlean. Factor Vs. Delta MAP
T2 - Decel. Enlean. Factor Vs. Injects in D.E.
T3 - Decel. Enlean. Term Multiplier Vs. Coolant Temp.
and the decel enlean factor is calculated from the values from these tables as follows:
DE Factor = 1 - (T1 + T2) * T3
T1 - Decel. Enlean. Factor Vs. Delta MAP
T2 - Decel. Enlean. Factor Vs. Injects in D.E.
T3 - Decel. Enlean. Term Multiplier Vs. Coolant Temp.
and the decel enlean factor is calculated from the values from these tables as follows:
DE Factor = 1 - (T1 + T2) * T3
