Tuning Webinar with Kane

You're AFR's need a lot of work, which will require changes to the Fuel VE Table and the Throttle fuel tables.
You need to work on smoothing out the curve before you worry about leaning it out for more power.
I redid your graphs in excel to make them useable.

So what you'll want to do with those logs is select 4-6 data points and get your RPM, AFR, and Calc Load. Then look in your AF Table for the gear you were in and look at your commanded AFR. Calculate the percent difference, then go to your fuel VE table and start making changes.
Take 2-3 logs, if you continue to notice those lean spikes you'll need to correct for those in the Fuel VE table too.
You were still online when we were doing that with my car right?

With my map, we started with Kane's base map in which the Target AFR's are already set where he wants them, so we can go straight into adjusting the Fuel VE and Throttle Fuel Tables.
I let Kane chime in on this one, as there are probably steps you need to take before adjusting the Fuel VE table.

I also forgot to mention that I am no longer running a stock tune. I adjusted the timing in the range Kane suggested, as well as leaned out the lower right hand corner of my fuel tables, again, as suggested. I didn't bring them all the way up to RBT, but certainly much closer.

You're are NA and working off the stock map, ideally I would think you would want to change your target AFR's to better suit the leaner target.

We can smooth that up real nice, but first we need to know the throttle position and the target AFR's from your MAP.

On the stock map your targets are not going to be RBT, they are going to be richer.
So before messing with the fuel VE table wouldn't you want to adjust your Target AFR tables?

Guess it's just 2 different ways to get the same end result.
Probably makes more sense to get the Fuel VE map right first so you have your Target and Actual AFR's correspond with each other.
Once that's done you can just change your Targets and everything should be good, right?

It looks to me like my percent error on the AFRs are pretty good. Anything above 4000 I'm only about 2-3% off. Below that I'm seeing 12-22%, but that could be because I was still in closed loop, and I was using the open loop values to do my calculations. What are the criteria as to when it enters open loop?

I'm less than 2% now. Time to take this to the next step.

How is everyone dealing with this lean spot at 6200rpm?
