So I have the car driving well and starting when warm with no issue. The issue is cold starts. It's a bitch to turn it over and fire when it's actually cold outside (like 50 degrees here...)
My IAC counts appear to be in the 40-50 range with the NW 102 and the TPS voltage set at .57V. It doesn't really seem to help much. Though, I played with it today and don't know how much of a difference it makes vs the .55V I had in there when it was cold (and wouldn't start).
Anyway, it seems like it just doesn't get enough air when cold. I have messed with the Startup VE table to make it match close to my primary VE table (which still needs some work - but I have been logging with the wideband at lower RPM).
I did add some idle startup friction airflow. I added 7.5g across the board, because why the hell not. I've also added something like 3 to 5g of startup airflow by ECT. I've had it there and it didn't matter.
One thing it's doing now after adding all that airflow (I didn't drive it around today) was in Park with revs, it is very much lagged now. With my wideband I've got it idling pretty well when warm. So I think the A/F is pretty close at idle and off-idle. It wasn't doing this yesterday after driving it around (before I added all the airflow described above). I had the TB open at .51V and it seemed to do okay. I wonder if the throttle cable is a little loose now with it being open another quarter turn to half turn?
Anyway, here are the logs. First is of the RussK idle config with it at .55V. I saw I needed more opening of the throttle blade. And opened it to .59V, but it seems engine vacuum pulled it back down to .57V and it settled there. The second is the same config but with me free revving it and it looking like dog shit (which is more concerning - either not enough fuel or something else like the throttle cable loose).
Tune is also uploaded. I'm guessing adding all the additional airflow is making it unhappy. I plan to retune with the wideband tomorrow after messing around with all the airflow parameters and to check the throttle cable.
Any other suggestions?
