Ok - I keep wondering why - and I remembered they changed how Baro was used in the fueling calculation. So I had a look at the release notes to verify my old memory and noted

-----------
Key changes and Gotchas
=======================
1. Baro
Previously the code used to divide by the barometer when calculating the fuel
pulsewidth. If using an old tune you need to enable the "old style" baro
calculation to enable the old behaviour.

-----

Did you enable old style baro calculation? As this enhancement would change the fueling requirement if you using the new (better/more correct) fueling calculation.

In any case, no issue as you have it sorted. It just bugs me when there is no clear answer.


Spot on. I didn't RTFM!!!

There was always a spot in the MAP/AN switchover which would autotune lean. Hopefully this is sorted with the new method as well.

For the record, I just had some time to play around with my accel enrichment.
Wall wetting definitely makes the difference with mine.

I put values in similar to GBX's screenshot and my accel was WAY too rich.
I slowly brought it down until it was clean, and I ended up back under 2ms.

So wall wetting seems to take away that requirement for big gulps of accel enrichment.

So are you using the default EAE settings? I have tried tuning it from time to time
but little luck with only one person. The logs do not provide deep enough information on the tables and look up values being used so hard to get an idea which way to go. Then there is also 6 tables to play with..... it is interesting all the same.

I think my settings are probably close to default if not the default, because I don't remember playing with it all that much.
So that would suggest it was pretty close out of the box.

"Wall wetting", now that sounds like something best done outside?
Any explanation?

Nassi, it's essentially allowing for the fact that when you inject the fuel, not all of it makes it to the cylinder straight away. Some of it gets stuck to the walls of the intake runner. At some point though, it will make it's way into the cylinder. Obviously in a multi-port setup, this effect is minimal, but still there.
On a throttle body injected system this would be much more pronounced.

There's a quick explanation here:

SO mine is pretty well dialed in now. I have taken a lot out of my accel enrichment now (It max's out at 12 with 2 @ 100TPSdot). The car is driving so much better and will probably improve mileage as well.

My LC1 wideband is starting to act up. Every now and then it will give crazy readings which would make a real mess out of auto tune.

Sensor might be dying. Pretty sure I have already replaced one on mine.
Drove to work today and mine is not great - I think I'm going to go back to my old settings, as it was pretty good.

If its the sensor this is my 2nd failure in 4 years so I guess I can't complain too much.

I try to make my tune about 5% rich on the trim so if the O2 sensor fails the car still drives well.
