KFNWEGM is like a threshold for fuelcut. When rpms drop, fuelcut is disabled from this value downwards. So if you want gargles and pops for the entire rpm range and all gears, set it higher than your rpm limit for example.
KFTVSA is the time in seconds i think before fuelcut is activated. But its active only when clutch is depressed. At least thats how ive seen it work on Volvos.
If you want bangs between shifts, lower KFZWMN in the lower load parts.
Sorry my english... (:
Where do I start at finding these addresses? I can't find them listed in the map pack I've got, and a Google search hasn't helped. Any help much appreciated |

As i said, you need air for the fuel to ignite. I know nothing about these maps, but find a way to keep the throttle open during overrun.

I don't know, just guessing, but even on overrun the throttle doesn't completely close does it? Would it not just return to it's idling state?

I dont kniw either. Easiest way would be to log throttle angle or smth during overrun.

And even if it is in idle state, one must remember that you need a lot more air for this amount of fuel to make bangs and flames. Stoich is roughly 14parts of air and 1 part fuel. Imagine the amount of fuel being sprayed into the exhaust and how much air there has to be for a burn to happen.

So its far too rich... how do we lean it out just on overrun? |

I've got
KFTVSA set to 0.8 second between 1K- 2K and 2.8 seconds between 2K and 4K and set from 60c
KFTVSAKAT set to 1 second between 1K- 2K and 3 seconds between 2K and 4K
KFZWMN set to -48 between 1K and 3.25K
I'm confused regarding KFZWMN. What is the X axis? I assume load? Is everyone just lowering the two rows at the lowest loads, to a flat figure? This seems like a big change, which is why I'm questioning it, perhaps I've misunderstood? See attachment. Thanks |
