Once you get to the point that your within 2-3% your pretty much done man.

That’s good but I’m having so much fun.

Then you need a new toy to play with while you tune

It does get addicting for sure

More DL for all your viewing pleasure. Histogram is filling up with 99s and 100s getting closer... Still need to tweak WUE again since it gets out of wack with every table adjustment seems to like 11.9/12 afr so at 12.2 it surges. Figured id leave it for now till the ve table is dialed in. Once the ve is good does ego get disabled or leave it on?

stanglx2002 · Apr 11, 2019

I leave the ego correction on as it's probably set to correct up to 5%. It's good as it will try to keep everything as close to 100% as possible

a91what · Apr 11, 2019

Leave ego correction in place, there is no reason to disable it at this point. If you are near 100 within the histogram i would call it a day for the fuel. you can try and add more timing at idle during warmup and see if it helps with the surging. 12AFR is pretty darn rich IMHO

I agree with Steve as I shoot for around 13.1 or so for mine

KZGUNS · Apr 11, 2019

@a91what Adjust that in cold advance offset? Start with a .5 degree? Or?

a91what · Apr 11, 2019

yes cold advance, you can try adding advance to it first.... some cars like the advance removed you can try that as well.

KZGUNS · Apr 11, 2019

@a91what thanks I’ll play around with it. This will satisfy my need to mess with everything lol.

KZGUNS · Apr 12, 2019

It seems perhaps 0 cold advance is what it liked. Was able to pull out fuel without surg. I’ll know more tomorrow when I can cold start again

KZGUNS · Apr 13, 2019

Cold start this morning went well with 0 cold advance. I could tell right away it was better so I started WUE Auto tune and its running great during warm up now around 13.1. No surging at all.

This is why i say nobody can tune a car in one session. It takes patience to get things dialed in just right, its good to see you getting her finished up. Each engine reacts differently that's what makes this so much fun

Ya it definitely takes patience. Out now with the car and warm start has a brief surg for less than a minute. What do I look for to control that?

a91what · Apr 13, 2019

look at the afterstart enrichment, you may have to bump the final full hot % value by 5-10%

KZGUNS · Apr 13, 2019

Ok I’ll give it a try. I was thinking about bumping that up. Thanks!

KZGUNS · Apr 13, 2019

I think I’ve got it. I added a little bit to the taper as well. Was getting a small idle surge after getting the warm start surge calmed. Added 1° in the ignition table around idle and that seemed fixed it. Get some drive time running around and see how it goes

KZGUNS · Apr 17, 2019

hopefully get some DL today

KZGUNS · Apr 17, 2019

@a91what its a big DL but the issue i'm having is easiest to find right near the end while i was getting the garage open, there are other times as well but its over an 1 1/2 hrs of DL

KZGUNS · Apr 18, 2019

@a91what Everything went well this morning! Drivability in traffic is night and day better! Idle is rock solid. Will see how it goes throughout today. Thanks again for your time and expert advice!
You guys out there struggling to get things really dialed in esspecially idle really need to make the time to get with Steve.
