ECMlink 2G Help w/DSMLink idle issue

[1996dsm]

im trying to find out why my o2 drops, and my car will run lean. i cant get the car to idle for more than a few seconds before i shut it off due to a/f ratio. ive set global and deadtime according to there sheet. my car runs fine with my other chip that i had it tuned on. im just not doing something right, ive watched ecmlinks how to's, and read some tuning forums on here nut still no luck.

The first thingi noticed was that your airflow per rev is way to high for your motor logging over .40 it should be roughly .25.
Once you get that dialed in better then post another log. Also what is your idle set at I can open up my link but don't have access to my car right now to diagnos your log.

At a quick glance:

1. I don't see any wideband being logged, so there is no way to know what your AFR is

2. Your O2 sensor isn't cycling, although with that short of a cold log, it's probably not even warmed up.

3. You need to log ISCPosition

my idle is set to 900.
also my o2 is not cycling but when it is raised on the first few sec. of start up, my car runs fine and a/f is 14.8-15 although idle is high. but then the rpms lower and my wb reads 17.8 and fluctuates between that and ---. and runs really rough, at one point i could hear a knock so i shut it off.

what would you suggest to try and fix the airflow per rev?

would i go down on the sliders?

When you first start the car, you are running in open loop...the O2 has nothing to do with anything.

Bump up the lowest 3 or 4 MAFComp sliders until the car will idle with a decent AFR. Then post up another log with ISCPosition captured. And, why are you not logging your wideband?

BTW - Have you adjusted the BISS, checked for exhaust leaks, and done a BLT? You have to have those issues knocked down before you can worry about calibrating and tuning the ECU.

I haven't looked at logging my wb yet, but I will asap. and I have no exhaust leaks and only leak is on my tb seal but its very little .
