[wtf777]

hi guys here is a log of my idle. i set it to 600rpm. here is tune as well. is this normal for timing to spike like that goes from 14ish to some time 26.
the first part is with ac on then i rev it ac off. let it idle a bit. then rev and ac back on. here is the log and tune.

looks like after not too many trial and error i was able to smooth idle out i will upload logs when i get chance.

ok now im convinced that the c7 lt1 idles wierd. i always felt like it idle wierd before i got hp tuners. now that i can data log i see that is caused from the random timing advance jump as you can see here on the log. it seems to get more frequent when the ac is on. the begging of the log is with ac off then about 45 sec in after a light throttle tap i turn on ac. the car drive fine btw.

Your not going to see any changes, but this should change your idle where it's most likely intermittently struggling to idle due to leaning out.

THank you! i loaded up the tune and let it run few minutes (im busy at moment) but i can already tell its much smoother. ill drive tomorrow. Thanks again

Yeah, people don't realize how important these background tables are You should have some more zip now too
