Sprint 500 Decel cut

Postby bontelabo » Tue Jan 29, 2019 8:33 pm

Hey, I have a Volvo with B230 engine. I can not find a solution for decel cut above 1500rpm and avoid the fuel absence occuring after enginebreaking and then activating tps while giving gas.

When stepping on the gas pedal to accelerate the car there is fuel missing for about 0,4 seconds. This makes the engine to stall and uncomfortable daily road driving. Is there any solution to avoid 0,4 sec fuel cut? Found the 0,4 sec gap by using data manager recording. I have raised the decel cut to above 2000 rpm and removed jerk and twitch but it makes higher fuel consumption for a daily driver. In advance, Thank you very much.
Regards Harry.

Not normal, but you would need to provide a map and log to see what you have done.
