Anybody got any experience messing with the throttle pump settings?
My car gets a little lean when I get on it, but just for a second, then the AFR's go back down. I'm thinking I'll shorten the vac line to the MAP sensor, but I also need to look at the throttle pump settings. Anybody have any advice on tuning this map? What settings work for you? The Haltech manual barely mentions this stuff. |
its kinda different for every car, but its the same as tuning a carb. theres 2 adjustments, one for the total amount of fuel, and one for the length of the pump shot. sounds like you might need to just add a little fuel.

Making the line shorter and using a hard wall tube makes a difference.
Make sure the TPS is in good condition, if you have free play in the shaft it will not work as good as it should when you step on it. |
Does the car hesitate on the throttle transient???
Are you staring at the wide-band??? If it's not hesitating, then don't **** with it! -Ted |
