ECMlink Just looking for any creative critizim (log attached)

90 awd 6 bolt bs delete presicion 5862 turbo running 20 psi presicion 880cc incectors base timeing 5degrees btdc base fuel pressure at 40 psi stock internals freshly resurfaced head and block with a felpro head gasket and arp studs torqued to 95ft/lb running speed density using a gm 3bar map and gm temp sensor and a mtxl wideband simulating. The car is running pretty good I havent had any issues Im more just looking for another couple sets of eyes to double check everything looks safe and point out any thing I may be missing. Thanks in advance.

Looks like a possible airflow smoothing issue from 4300-4400. You can see afrest spike and cause the wideband to dip. Car gets richer as the pull goes on so maybe take some full out. I'm not qualified to comment on much else.

I thought if I had the box checked disable airflow smoothing w sd the values in da didnt matter. Is there somewhere else to work on that or just the Ve table?

It's def rich toward the top of that pull. During idle, bring your tps down to .63, and iscposition to 30ish. You're front o2 isn't cycling either.

I'd get the afr's to line up and smooth the SD table.

It looks like you may have a small boost leak with the boost moving around in little increments like it is after 6 lbs or so. Maybe TB seals.....just critiquing the log, it's not bad but should be solid.
Global setting is a bit fat too.

I would scale the injectors, try to force the car in closed loop longer and get the ve table to self tune itself from there. I would also change the direct access fuel table and get it to be a little less rich. Overall it doesn't look bad and its a good start to get going from.

With the car not in closed loop would the isc still need to be at 30 ish? At the beginning of the log the AFR was 7.4 so I assume you just started the car again and the wideband was warming up?

That’s a good question. I don’t THINK the isc is affected by open/closed loop but I’m not certain.

It's been a long time since I used a stock ecu. I remember going thru all the wiki's on ecm links page and trying to get everything right. Good times.

Correct

Dont no if this would affect anything but im currently running without apcv of any sort

Most likely wb was heating up.

Good question. I'm not certain but I'd just set it correctly since you have the ability to. Remember it can burn out the driver on the ecu.
