throttle enrichment problem

Postby T-Bird24 » Tue Nov 27, 2018 1:06 am

G'day
this maybe a weird question. But can i tune an engine without throttle pump enrichment. i am using an E11V2 ecu, and i am having issues with the throttle pump settings over fueling on constant throttle. its fine with quick short movements. but once held at a constant rpm and load it is over fueling pretty bad. causing the vehicle to blow black fuel smoke. i have been changing the base fuel map to even/smooth it out. it doesn't help. ??
I have changed all the settings in the throttle pump setup, no change seem to make any difference. I have noticed that the engine data list in the throttle pump setup table seems odd. TPS and both async and sync map, the data jumps around a lot? Could this cause an issue?

There is a dead band setting to prevent this, and perhaps you need more filtering on your TPS. Especially so if you are truly constant on the throttle and it is tripping the enrichment.
