Hondata

Hi hondata,
I have two versions of my afm cal. One with map fuel and one with afm fuel.
Both have the part throttle fuel tuned.
Using the same fuel overrun numbers in both.

The afm fuel cal is very smoth off the throtle, the afm cal with map fuel is not. This hybrid cal have a litle jerk off the throttle in 1 and 2 gears. I changed the fuel overrun numbers but it's only a litle better. It's better when i put lower numbers. But the afm fuel cal is always better.
Is there any reason for this as the fuel overrun numbers are the same ?
Can i make the afm with map fuel as smoth as the afm fuel cal?
Thanks in advance

Change the 'Overrun fuel cut delay' to a higher value in the lower gears.

Check you fuel values on the 0 degree fuel table for overrun. Typically this table does not get tuned and gives a rich / lean condition that spikes the AF.

Thanks i will do this.

Hi nuno,

This is the same issue I had remember:

It still feels a bit jerky but not as much.

Hi hondata,
Only to tell that I am now using the Vtc tables upon decel fuel cut and the car is much smother on lower gears off the throttle. Getting of the throttle and not going immediately to 0 degree cam angle is much nicer.
This new beta is great for the fn2.

Thanks for the feedback.
