Hey guys! Looking for any input on this current issue I'm dealing with. Ive been driving the car occasionally all stock with no issues for a few months untill recently i did some work and changed my timing belt, added a fmic, upgraded the fuel system, and set the car up on speed density with ecmlink v3. Now the car will not idle on its own. It will run for a few seconds then die out. If I pull the vaccum line off of my blow off valve the car will idle with no issues (doesnt run the gratest because it is untuned, but still idles on its own) Im trying to figure out if my issue lies within my setup under the hood or in the ecu configuration/tune. Im trying to get this resolved so that I can have the car tuned professionally. I will try to get a video up to show whats going on, thanks for reading. Any input is appreciated!!!
 
what size injectors? if you have larger injectors and aren't tuned for them you'll flood you engine out which will run for a few seconds

My injectors are 1800cc. I used the calculator in ecmlink to give me my global fuel percentage and injector dead time. I tried different base fuel pressures also with no affect.
 
97 eclenger meant at idle if you didn't know.
Yea it pulls about 20 hg but it's idling at about 1600 rpm. My fuel pressure is set to 43 psi at the regulator and in ecmlink. And this is only with a vacuum leak, car will only idle for 3-4 seconds before dying with all lines connected.
 
Sounds like you have way too much fuel

You can also go back to the old injectors and tune to see if it runs fine. This will rule out any possible mistakes when changing the timing belt or other mods.

My other option would be to try different base fuel pressures but seems like you already tried that.
 
Finally got the car running! Turns out I had the wrong map input selected. Now I'm dealing with a super rich idle, I've been reading for days and I've tried a few different ways to remove fuel. I've lowered the numbers in the upper left hand corner of the ve table and also tried messing with the global fuel and dead time and I still can't get it right. The car is huffing black smoke and my wideband is pegged at 10.0 any suggestions? Still trying to figure out how to log the correct values and get them posted
