I just started having this issue that around 0-2% throttle the fuel goes from around 3.2ms to 1.3 and makes the engine die. I've looked at all the settings fuel wise and could not find anything that would cause this. Is my newish haltech sensor going bad or could it be something else?

 

We need more info:

Are you using the 0 throttle map?

How stable is your RPM (glitches)?

Do you have decel fuel cut enabled?

I don't know a lot about E6Ks, but if they are anything like E6Xs, there are a lot of settings in them.

My current guess is trigger noise or a loose connection on a sensor.

Did you tune this yourself, or have someone do it for you?

 

Tuned it myself. Runs pretty rich at idle wideband shows around 13. Run mainly off of the zero throttle map since the haltech idle motor runs at 0% thottle which is very hard to get this thing to have a steady thottle % of 0. I have the fuel cut enabled aroun 1800. Rpms are those of a bridgeport(all over) around 1300 to 1500. It seems there is a dead spot that keeps me from getting the rpms a little lower to lean the engine back out to normal. If I hit the gas and let it close itself sometimes I can watch the injector ms go to around .8 to 1.2 to where the engine will die unless I hit the gas again.

 

13 is normal idle A/F ratio, this is a streetport, not a bridgeport, it should idle smoothly at 12.5:1 to 13:1 at 1000-1200 RPM.

You can try retarding your ignition timing at idle.

You might also look into your throttle and make sure that it isn't closing further than you would like if let off suddenly.

The 0 throttle map is definately your friend.

I don't understand the duty cycle dropping like that, just telling you what worked for my idle issues.

 

I mean't around 11 not 13. I got somewhat better now except the rich part. The whole glitch thing went away for some reason.
