ECMlink Lean idle....

[johnovision27]

Heres the issue, every time when i'm idling, my AF ratio climbs beyond 18:1 and the car wants to die. Because of this, the car wants to die when ever it's stopped at a light. I have to brake and keep my foot on the gas to keep it going.
From the stop, when I try and accelerate, it's very laggy/jerky (very VERY lean is the reasoning i'm assuming...)

I've been trying to do some research into this, but I'm finding it a little tricky as this is my first car with ECMlink and this is my first serious tuning tool.
Attached is a log.
I'd greatly appreciate some input.
Thanks folks!

Might have to enable view for the AEMwideband.

I am unable to look at the log in my phone but have you tested for boost/vacuum leaks? We all know what unmetered air does when sucked it.

vac leaks checked, nothing.

It smoothens itself out after a while (normal clean idle and bouncing from 14.2-14.9) and then will suddenly come back with out warning. ... grrrr

it appears that your injector settings are off a bit. your link fuel settings show that you are set up with 680's at 40 psi of fuel pressure. just a thought.

BOOST LEAK TEST... I would concentrate on your injector seals. Those lil bastards can leak un-metered air into the manifold causing a high idle and a Lean situation.

Hi there,

If you have checked for leaks and found none, then also check your injector seals as recommended. If all that is fine you might want to look into your o2 sensor. I had a similar if not almost identical condition not long ago and it was that. Changed it and my car idles perfect now.

 

[johnovision27]

Checked the injector seals and it is a good recommendation. I had a leak there before.

I've figured out what it is, or what I believe it to be, no judging!!! haha
The vac produced by the 2.3l is a hell of a lot more that of the 2.0l.
When I bought the car, it had a Greddy RS BOV with no recirc fitting *BAH!* but there was no leak there. so i left it as the car idled fine.

Now, the vac in the intake is opening the BOV when idling. (explains why I missed it during the precious boost leak tests) I have the recirc fitting but am having trouble finding a line to go from the intake to the BOV. I'm looking for the black rippled one that other DSMs have used to solve the issue.

In autozone or advance auto parts you can just tell them to let you look at the Radiator hoses that they have and I'm sure you can find one that has the angle you need to recirculate your BOV.

Problem was solved. I got some 1 1/2" pool vac line from Home Depot. Fits snug, very flexible, and looks pretty damn good!! (Black with blue trim)

Nice, as long as it works fine.
