Hi guys,
I just got my FRS and a ECUTEK tuner but I have been tuning engines for years, started with holley carbs...
I think that it's more about drive ability...
I'm going to run both at all times to eliminate the transition point from DI to both...
Turing PI on and off and on again makes no sense to me. either on or off or a mix..
I have to do some tweaking, I filled in some gaps with 10% PI and it seams too low but it still runs better, so I'll go to a min of 20% PI at all times....
The 35% - 20% PI part of the map run better to me than either 0 or 10%...
