LTFT doesn't always set over a long time. Sometimes - often, really - it is nearly immediate.
It depends on a balance of ECT and the amount of time spent in a particular breakpoint.
I've watched LTFT build 4 or 5 points in a matter of seconds if a "pocket" in an otherwise smooth breakpoint is covered in equivalent STFT. But only if the conditions were right.
I've also watched a breakpoint suddenly build 3 LTFT points out of nowhere on a tune that was stable for many, many months because the right combination of load and ECT were met because of a change in BARO and IAT. I've also watched that same tune dial out that same LTFT the next day.
The methodical way to approach this is to find the breakpoints (though there are 5, only 3 really count) and learn to build a realistic fuel curve that matches the MAF to resultant AFR, after you have identified your relative injector scaling.
Also, you have to actually understand what the CL tables adjust, not what they seem to adjust.

These breakpoints ... I imagine are not as simple specific Maf points on the scale are they?
I'm guessing the breakpoints are set by Maf, Calc Load and RPM?
So the CL Tables do more then act as a modifier to the target afr on the A/F table while in CL?

Question: What happened to all that trim we saw in the first log files. Did you reset the ecu? How many drive cycles on these logs?
The cruise logs look pretty good to me
WOT 3 gear between 3.42 to 3.67volts are a bit leaner than MBT could maybe use a +2% to those cells and smooth out transitions and re-log
WOT 2 gear between 3.85v - 3.9 v is a little bit richer than MBT ... could take -2% away
I only see 11 afr's when you are off throttle ....

My LTFT changes right at 1.8 volts so I was guessing it was a break point or are these more virtual break points.
Oh that and the fact that MM speaks to them in his webinar

Here's my 2nd and 3rd logs from yesterday and today. Today's were the same but richer overall by a tad, mind you its cold today compared to yesterday. Gonna start working on a Maf cal in a spreadsheet.
For the Dips at WOT
2nd Gear they 5-5.7 and 7.8k+, Maf is 123-141 and 195-211 in those ranges.
3rd Gear they 4.7-5.6 and 7.4+, Maf is 108-138 and 189-208 in those ranges.

Team, I think a few people including MM have said there isn't an seminar right now. I think we all get the point and you can stop mentioning it now.

Got rid of my rich spot with the maf, now i basically just working the small deviances. Thanks wcs for all the help off the forums. enjoy the golf and beer tomorrow lol.

Please read all before you reply. I need to vent bad.
Team your a dick, you took the seminar so you know what to do, I am sure once I understand the way it works, I'd be able to do the same, But maybe I like figuring out things on my own. Not taking the seminar doesn't make me the idiot your implying I am. Bet you took the seminar atleast twice. Plus you have owned your car for probably more then 5 years, I have had mine for 5 ******* months and I am practically almost there. So go shove your ego and that bag on your head up your *** and **** off with the ******* seminar, if I want to take it, I'll ******* take it. And I'm not your ******* bub... *******.
MM, I'm not saying anything bad towards you or the seminar, I'm just sick of team's constant nagging. It's a pet peeve and it drives me ******* nuts.
Hope all the swearing is alright. Now that I vented my anger, Team I seriously have no problem with you. just please stop nagging about the seminar, as i said its a pet peeve and it drives me bananas as you can see. Now everyone knows, don't nag at me over and over, you'll pray you never meet me in real life lol. Peace out, gone to self learn some more. so team can bug me some more hehe. :P

Team and Wcs are like polar opposites, team drives me bananas with his comments sometimes and Wcs has given me more help on and off the forums then probably everyone else here combined. Wcs if we ever meet in person, I definitely need to buy you some beer. MM might get a beer too, I sure I'm making his hair gray haha.
And team. I am running my 6th iteration and working on #7. Not bad for what you think is a total noob.

I think what Team is driving at is what is called in economics "the dollar value of time".
Many of us like to figure things out on our own. I did. This stuff didn't exist when I started.
But, it can be suggested that your experimentation time might have more value if it wasn't going verifiably in the wrong direction.

I doubt its going the wrong direction, my AFR's seem to be almost dead on now, minus the valve spikes. Can't verify until it stops raining though. To be honest, I'm happy with the results I am getting, I expected it to be a lot more difficult when I bought the AP hence why i paid for the CCS just incase I couldn't figure it out. I only having 1 real problem right now but I can live without it. Is it possible to tune for 3-4k in CL, the car seems to be fighting back. I getting 14's where its set to 12.9 and i got -8 stft. My CL table is set to 1.0 in that area. Is it even possible to get 12.9 in closed loop even if you set it to? If I can't get it, no loss. Just thought I'd try for it.
