Probably needs more airflow in the base idle airflow table? Is it doing it just when you come to a complete stop?

Yea i added 2 across the board? When its cold its has a rough time coming to idle. Then when im in gear it wants to puke out but only sometimes?
Is it going lean in both cases? I'd keep adding airflow until it runs better, only issue with too much would be the idle will want to hang, I think.

Thank you, it stays running. It surges tho. Also i looked at your timing. What is your method for adding? Do i add across the whole board until i get knock and then use the spark knock graph and subtract where i get knock??? Or is there a way to add in sections?
Do you have a log of the surging?
I adding timing to high map/ cruising & WOT areas until I started to see if kick up little bit of kr, then backed off a bit. Then I used that increase and worked my way back into the lower map areas. I didn't find the limit to what kicked up kr for every region of the table, moreso the medium to high map areas (60-95 kpa) throughout the rpm band. Really light cruise areas I haven't noticed any kr.
Someday I'll dyno it and see if it wants something different than what I found.

Im having some troubles w my wideband reading different on my gauge than in my hp tuners. How did u wire your plx? I have its own wire straight to my pos and neg on my batt but it is reading 10.? And my gauge is 14.7?
Are you using the correct transfer function? It shows the correct AFR on the wideband's standalone gauge? b

Tranfer function? I created a channel and used the already made plx wideband one?
Okay that should be correct then. Just to be clear - do you have a standalone gauge for the plx that is reporting the correct afr? Then hp tuners reads it incorrectly?

I was in the wrong one, thanks
I had taken things out and when i put it back in i thought i used the 2nd port...so i was in the wrong hp tuners slot
Glad you got it working.

Man, I just read from page 1. Wow! What a learning curve! All I can say is thanks guys! I couldn't have done it without this forum. I wish I could take you guys out for a beer. I really appreciate the help
Its crazy how much there is to learn when first getting started; I know I definitely had a lot to figure out, but that's part of why these forums exist. Happy to help out!
