Need help with idle. First timer

[apedog]

So ive been reading as much as I can about ecmlink and how to tune but I have a problem now.

I have a 1g automatic with PTE 680cc injectors and a walbro 190lph. and I cannot get the car to even idle right. I read that my deadtime is basically how I add or take out fuel for injectors right? I found that 310 is the deadtime for these injectors but when I put that in the car will not even idle by itself, like I have to keep my foot on the gas to keep the car running. My global is -34.8. My fuel pressure is 38 and no I do not have an fpr. I had the deadtime set at 700 but that is the only way it will even idle and I know that isnt right.

I am running dsmlinkv2 in v3 software.
Can anyone help me

Terry's Talon Troubleshooting Tips #3 - Fast Idle (aka. Idle Surge)

first of all i would read this thread basics when you have idle issues it could be many things affecting it, i would begin to rule out things one by one.

I dont even have idle surge. The problem is the car wont run with the right setting but if I put the wrong setting it runs fine but throws everything else out of wack

Here is a log with the deadtime set at 705. It should be 310 im pretty sure

Fix your airflowperrev to .24 and your ISC sensor is pegged out.

Your maf clamp doesn,t look stock either. Try loading stock ecu settings in then start with changing injector data.
good luck

Im not an expert in this as i am really new at doing this. Your running very rich.
First try to get you ISC to a good position (30)... Your aimed idle is at 850 and your steady at 800.

then get your Airflowperrev up to around .25 ... Readjust your MAFcomp as its reading to low.. Id 0 it all out first.

That should bring your CombineFT up a little. but try to get it around +/- 1%.. Add deadtime to lower, remove to raise it.

Put your MAF Clamp back to stock.

Im no expert... but that is just what i would do.
