Just wanted to bump this up to say after trying everything suggested and still not being able to get it dialed in Kevin not only got the idle cleaned up, I also went ahead and got him to do the WOT...

for some reason if I try to log with it in the scanner the afr glitches around but shows a solid number on the gauge itself. thanks for the help this far ill try it in the morning, ive reached out to...

It’s at the end of the downpipe. It’s an AEM gauge with the connector to tie it into the hp tuners. Yes it’s a couple post above. It’s called idle scan 3

Was able to spend some time on it myself this afternoon and I finally feel like I’m getting somewhere. Can someone tell me what my injectors pw should be at idle? The idle is almost completely smooth...

if its a true cold start the surge is there until it hits 160*, as soon as it gets there the surge is almost gone. only does it sometimes once warm but corrects itself. new idle/driving log...

tried the file but couldnt get it to idle, heres the scan from that one

Increased the map max, put the factory tables back in the over/under spark. And I?ll figured out how to add fuel In that area of the VE. If I were to increase to spark table how much at a time would...

Did everything as suggested I believe and it?s still surging. file and log attached

Since that method cuts everything in half, how does that affect any airflow or fuel changes that are made afterwards? As far as if I would normally give or take 5% would it then need to be 2.5% ?

I don’t believe it was checked to see if the multiplier works. This was another thing I was going to attempt as suggested. Will it work with the 2 bar OS?

The table is maxed out to the same flow rate because the injectors flow more that the table allowed with it sloped. This was done per the tuning school method using flow rate vs Volts
The injectors...

The map should of been set to 200/8

Non return factory fuel system other than the walbro, stock TB
Cam is a 212/218 550/550 114lsa
Injectors are 25317628

Switched over to the 2 bar OS, got the VE table worked out and the fuel trims within 5%. Idle surge definitely isn?t as bad. With the coolant up to 180-200 it may be around 75 rpm every...

Ok I’ll do some checking on that. Thanks for the info

After the 2 bar OS. If the tables are zero’d out how do I get all of the VE data for them?

Also since I didn’t have much data with the injectors can someone see if the data that is entered is good...

Yea that sounds like something that needs to happen. Theres not much data with my injectors so I’m afraid the method you suggested may be difficult to set up.

Summit showed it to be a GM 2 bar map good for 14.5psi

So using that method would I return all the changes I made already back to stock? I’ll look for a write up
The map is an AS314
I’m not sure if the Y axis has been changed but I’ll check everything...

heres an idle log

Got it, thanks!

I finally received the tune file but apparently don?t know how to post it. Can I email it to someone or someone tell me how to post it

I am not the tuner but trying to assist where I can and learn in the process.
Background on the build is 6.0. 80e swapped. Walbro in tank. Decapped injectors. 2-bar map. 78mm turbo. All the fuel...
