all my timing marks are on, ignition timing is on.

I have a high rev of over 1k.

my timing should be at 5 -10 at idle right?

5* is base timing, 1g or 2g. 1gs run more timing due to lower compression, but base is the same. Your isc good? BISS?

Just noticed your log. That doesnt look that abnormal, but id have to compare it to some old idle logs on my other computer.

i think your idle is a bit on the high side, and your timing is naturally climbing, Ive noticed these same numbers when i take my idle past a 1000.


I cant get my idle to go down no matter what I do it seems.

I did a boost leak test, fixed them all.

I adjusted the biss screw to 30 (log says its at 28)

tps is where It should be.

Any ideas?
 
A few, throttle cable tension and play, or the stop/ screw that stops the throttle blade from closing all they way may need adjustment. ISC motor, check the resistance.

setting idle adjustment to 0%.

More messing around with idle numbers set on link, idle tune adjustments.........
 
Try simming idle switch? I see "idlesw" is logging "0" so, its been awhile since i messed w link, but i would say that means the ecu does not think you're idling. Click the "simulate idle sw from TPS" box
 
I changed the isc motor. now this is my results. nothing else changed but me installing my spare isc. was my old isc bad? that's a drastic change to idle by just swapping out a sensor.

Ok, I dont see idle switch enabled still.

I also dont see a narrowband 02 signal, and you're not locking it in open loop so im a bit confused. Maybe its something im missing or something different.
I would sim narrowband to get that straightened out or look into locking in open loop(not familiar w that).

Is there some different setup im not seeing here as to why you dont or cant get your ecu to log idlesw? Again, as i stated above, try clicking simulate idle switch from tps.

If im off base here someone correct me, otherwise im seeing a couple problems right off the bat.
