Ok so here is a change to the tune please datalog this for me with some revs and rev and hold... looking to get you a useable fuel table.

Ok will do

that was a rough start! It did smooth out though. AFR looked good after a min or so when it smoothed out. Had a few flat spots while revving. It did hunt a bit near the end of DL. I restarted after all this and it started and idled pretty good.

Another rough start. had to work with it to keep it running at first. I also bumped the key and shut it off, it restarted but still a bit rough. it seemed to smooth out once warm and near the end i shut it down to see how it would restart warm and it did pretty good. I didn't realize till after i first shut it down that the DL keeps going, guess next time i'll start it before i start engine.

ouch that looked terrible on warmup... the fuel is still way off, lets see what this does..

KZGUNS · Jan 28, 2019

Ya it was as rough as it could get lol

a91what · Jan 28, 2019

Once warm she does just fine though

KZGUNS · Jan 28, 2019

Ya the idle is great once warm. It was 35° in my garage when I started it. Later this week our high is -1

ok here you go. engine was ~100* at start up, still kinda rough but soon after Wue is done it smooths right out. there is a lean spot right off idle i assume that's because the fuel is catching up?
Near the end i shut down and restarted and it did well on restart.

Before we can do any accel fuel tuning we have to get the fuel table tuned. Have you considered a tuning class? Even an hour will get you to the point you can take over the tuning with confidence.

Sure I would love to learn more!

This should get us closer to something reasonable.

here's the data log from this tune. something to look at till sat. It was less rough cold but still rough and surging till 165* then it smoothed out. Looking forward to Saturday.

was able to get this out on the road today. I did about 20-25 min of auto tune on normal, then drove again to data log. Cold start did surge till up to temp. It started easy though. During the drive everything felt good, no stalling or anything.

Cool, I need the tune from after the autotune session. Then I can take a look to see what we need to talk about during the next class.

KZGUNS · Feb 3, 2019

here you go
