I adjusted the "Overrun Fuel Cutoff" setting to
"Overrun Fuel Cutoff TPS"
Throttle : -10%
Delay : 10ms
"Overrun Fuel Cutoff MAP"
KPa : 8 (across the entire table)
"Overrun Fuel Cutoff Initial & Return"
RPM : 8000 (across both tables)
That got it working sort of
I then set the ignition timing where I was at during decel to 24 degrees (from 1500-8000 on the far most left hand column)
And added just a bit of fuel to that area as well
Doing all of that keeps the afr during decel between 14.5 and 16.5 which allows the car to make lots of nice crackling, popping, and burbling noises which I love.
I'm sure not every car would use these settings and I'd imagine it would depend on each individual setup based on injectors and what type of fuel you're on (I'm on e85).
I also don't know if this is detrimental to the motor in any way so I'm not going to suggest anyone do this to their own car unless you're willing to risk the unknown effects of this over a long term duration.
But what parameter do u change and what do you set it to? It only lets you edit the MAP vs RPM On that sectioncurtusz wrote: ↑Tue Dec 04, 2018 11:34 amJust alter overrun recover/restart .. it will just gargle and pop away on deceleration .. kinda annoying after a while for me personally .. I would recommend having as a second map on the flashpro just so you can change it back easier .. also can't really be good for cylinder walls and piston rings .. bore wash and all that
Which values you entered? I have tried a lot of parmeters - but the only what I have figured out was at "light throttle" the engine pops. But I would like to have the pops if the clutch is pressed to change the gear... And this is what I did not archive yet because the injector cut come in rapidly and this can not be changed I think...curtusz wrote: ↑Tue Dec 04, 2018 11:34 amJust alter overrun recover/restart .. it will just gargle and pop away on deceleration .. kinda annoying after a while for me personally ..
