Adaptive Fuel Table ?

[cbman]

I purchased the PRP book along with the PRP software for my XCal2. It was some good reading, but I didn't think it was worth $70. I probably would be ok without it considering all of the info that is available on the sct forum.

Anyway, I was wondering what values should be in the Adaptive fuel table? In the book it says to set all of the values to a positive number like 3, but later in another section it says to set the high rpm and load values to 1 so it can transition to open-loop faster. So, which should it be?

I think you should leave the adaptive table alone. I've messed with it before and found no benefit to changing the stock values. For dyno tuning you can turn it off and get the car dialed in first, then turn it back on. There are only a few values I change for adaptive learning for forced induction cars.
Mainly that table is only valid for learning at idle and cruise anyway. You WANT the car to drive stock under non WOT conditions. You want it to be able to run optimum in closed loop. Based on this why mess with what is working?

If I were you I'd spend more time learning the timing tables and the base fuel table. That is where you can make your money at.

I just wonder since it says in the book that setting some of the high rpm/load values to 1's allows it to transition to open loop faster. I'll probably just leave it alone.
