To be honest, that's just my excuse to change that table to see if it will cause the IAM to recover more quickly when it does drop. I do agree with that there must be an explanation for it, though each time I've seen that happen I've tried to replicate it in a log to no avail. When I try to capture the IAM dropping, trying to replicate the conditions in a log it simply doesn't happen. It happens very infrequently, and when it does happen it's typically during a long distance drive on the freeway with extended period of having the throttle held in a particular position. Have you experienced it before?

No, why would i care about iam or power or logging for that matter on the highway? My timing map is so smooth that any iam drop is due to cl fuelling or insufficient learning time or avcs or whatever, not timing. Also we rarely have flat highways for miles here like you do.

I don't know about you, but I'd be concerned about how my engines is performing under all conditions. Maybe that's just me. But I get your point. It's not likely that something funky would happen under low stress situation especially after you've done your homework on your calibration. meh... To each his own, I guess.

You're assuming that your engine is under performing 0.3 deg of ign adv less under low load ? I think most tuners would laugh at that.

I tried "stressing" the engine a little to see what happens in terms of the flkc and if the IAM will budge so that I might see the effect of the changes I made to the fine correction tables.

This is on a .5 mile stretch of road that I time myself on that starts on a steep downhill grade through some tight turns then a steep uphill to the end. http://datazap.me/u/solidone/kc1-par...zoom=4988-5585

This didn't even tickle it's belly even though oil temps climbed to 230f* (which is actually not too high). FLKC is completely flatline here. I guess I'd have to take it to the canyons or track to really see the effects on this particular tune I'm running. Otherwise the only other way is to load 2 calibration starting the IAM at .5 or so then see how the IAM get built back up to 1 with the changes then once again without the changes to the fine correction tables.

To test the changes I made to some of the fine correction tables I went ahead and changed my original "Z6" tune to start at .5 IAM with no other changes (left side of the image above), reflashed then took a log to see how quickly IAM builds up to 1. Then I flashed basically the same tune with the changes to the 3 tables I did in an earlier post. I'll call it "Z6 KC1" test tune.

Z6 test tune log: http://datazap.me/u/solidone/z6-iam-...1&zoom=30-1107

Z6 KC1 test log: http://datazap.me/u/solidone/z6-iam-...&zoom=405-1273

I'm not sure if you can tell by looking at the log, but the changes I made work as expected. While the Z6 tune did not take very long to recover IAM back to 1 the Z6 KC1 tune did so quicker.

Another thing I've observed is that the FLKC never went above +1 in either of the logs. As the IAM increased the +FLKC values became progressively lower. I'm not quite sure whether changing the Fine Correction Stored Value Limit from 3.5 to 4 contributed to a faster rate of recovery. @Kodename47 I think maybe you have a better idea of what this particular table is doing than I do. Though, from the looks of it, I think increasing this value is pretty irrelevant to what I'm trying to accomplish, yes?

For shits 'n giggles, another run at the .5 mile road. FLKC still flatline. http://datazap.me/u/solidone/z6-iam-...zoom=1502-2261

From memory, the FLKC table should be cleared upon every IAM change. FLKC values, both positive and negative, are dependent on the Advance table. I doubt you'd hit that 3.5/4 value and while I would suggest that a lower value might make it restore quicker, it's not something I'd go changing.

I decided to add some more ignition advance to the existing calibration I've been running as it seems the fuel quality has gotten a bit better recently. Also out of boredom...

I added about 1 degree right in the middle of the power band from around 4~6k to see if it will make a little more power. From the looks of the initial logs it doesn't seems to be doing much if anything. I'm sure the IAT's likely has something to say about it. @Wayno do you have any logs of your setup on 98ron petrol that you can share?

Updated with 1 degree more advance: http://datazap.me/u/solidone/z6-kc1b...1998-2027-2037

Previous: http://datazap.me/u/solidone/z6-kc1-...81-290-300-311

edit:
Digging through my old logs I found earlier versions with more conservative ignition advance maps, same cam tables:

MAF voltages higher than my current peaking at 4.13v (current peaking at 4.05v with about +10*f IATs and likely a few less WHPs) : http://datazap.me/u/solidone/cw1z2-1...4951-4943-4935

You put the values in the wrong system of measurement.
