So my car has this stupid-rich-when-started-cold thing that I've been dealing with

[Keyan]

I will test this out this afternoon.

So I changed the "Seconds" value in the Closed-Loop Warmup Inhibit Time to 0 and the car starts up and will idle at 14.7 now, but when I begin to move it still goes to 10.0. I am thinking I also need to 0 out the Closed Loop Load Inhibit, yes?

There is a reason the warm up enrichment is there. I would keep it and just lessen it's effect.

You don't want the narrowbands to go into closed loop right away... They haven't even warmed up yet. Their readings are very inaccurate till they have heated up.

Please don't tell me you changed just that timer and left warm up enrichment as stock.....

Take note that I only disable this on cars with large injectors which also typically run with e85.

Warm up enrichment is purely an emissions device to get a catalytic converter to warm up quicker. I could care less how quickly my car goes into "protect the environment" mode. (ie; a fully warmed up cat)


Fun fact: warm up enrichment doesn't exist in new cars, espeically hybrids. They use coolant or air pumps to get the cat to warm up.

By disabling you just set all the values to 0 in the warm up enrichment table in the fuel section.

I did what you told me to do.

There is no "warmup enrichment table".

There is "warm-up enrichment vs load" "coolant temp fuel enrichment" "close-loop load inhibit", "Closed-loop warm-up inhibit time"


I am working with the information you are giving me.

Warm-up inhibit time charges how quickly the car goes into closed loop; you said that the enrichment is from an open-loop mode, so I disabled that enrichment. Unless you are explaining this to me all wrong.


EDIT: sorry if my posts come off as dick-ish but its frustrating to be given keyword and not have that keyword come up in the table list, and then to be talked down to after not doing it right. I am trying my best here

[Greg E]

Coolant temp fuel enrichment is the table I was referring to. Ignore the warmup enrichment vs load for now.

Warm up inhibit time is just the delay after staring that the ECU goes into closed loop. Don't ever go lower than 5 seconds for that. I would at least leave it around 30 seconds for the winter temps.

Jim, post 2 and 3 should be a lot more helpful.

Don't swet the semantics. We will get you tuned.

This is exactly what my car has been doing! Doesn't always do it though even at cold starts. Has been worse lately so much that if I don't hold the rpms up around 1500-2000 for alittle bit that it will die. I will make the adjustments said here and see if that helps.

[Greg E]

Did you get it straightened out Jim?
