Adaptronic Fuel Cut
#4
Thanks guys,
Yes I do know this but nothing was changed on this from last year. Here is my settings. It worked last year. I did change the map around a bit so who knows what I touched but the throttle over run has nothing to select fuel cut on or off?

2) You could tighten the RPM gap to 100 vs. 200rpm. 1500rpm to 1600.

Having ZERO delay means that the second you pull out of the throttle (from any RPM over your cutoff), it cuts fuel, which more than likely bucks the car like a light rear (RWD) brake application and sends weight to the front (not ideal for mid-corner). In the same sense, when you get on the gas again, you'd want to have an asychronous burst of throttle to re-wet the intake runner walls, right?
It'll keep AFRs more consistent and smooth out tip-in, from my understanding. I could even see going up to 3-400ms on a beefier ported engine... Just seems like it would effect drivability, no?

I'm not sure what kind of driving you do, but a crisp tip-in and out of the throttle happens a LOT in the canyons and even on highway driving.

I was thinking that another benefit of having some delay is so that the fuel cut doesn't activate between shifts. Having something like a half second delay would allow you to quickly shift gears without hitting the fuel cut in between.
As far as when you get back on the gas the asychronous gain setting and the predictable map table being properly set up will be the solution. The "pump" column you see in logs represents the extra burst of fuel from this setting.

Well been busy. Not much time to mess with the car. Oddly enough when I changed to another map for some reason it looked like my dashpot settings changed. The manual does not indicate that the dashpot settings (on idle page)has a correlation to throttle-off overrun in the power cut page. (I might have missed it or was using an old manual) but adaptronic was quick to point this out to me when they tested my file. So I have now changed the dashpot duration to 0 and away I go. Throttle cut is now working.
Thanks,
Thanks,

I also had this issue, I accidentally put a value in the "primary 2" injector size field, and it began to run in triple stage mode which made my throttle off/overrun stop working. Put that value back to "0" and it was fine.
