That log is with minimal scaling, 3.1/2 percent above 3.4 volts. HOWEVER, if I scale my maf to make my fueling follow my OL tables, I have to scale my maf so high, that I see 2.6+ load and over 230 g/s. I do not have it scaled that way as it creates such high loads.

So mid to high 11's until 4k and then drop it off to high 10's to 11's?!

I just don't understand why my lc-1 is so far off my OL table. I will post a log int. file with my OL tables vs. that log. In places its 10% off the OL table. I would love my afr follow my OL table... but I'm to the point with my maf that I doubt it happens...

Here everything is loaded, just notice the afr % of correction needed. This is exact map that is being used.

Mickey,

Here is a Learning view from today, it went from 65 yesterday to 90 today. Atm. is still at 14.51. I think I'm pretty close, as D range was 0 yesterday and is at .1 today..... No knock. And the Accel chart on the log file with just rpm/speed showed 248tq and 233 hp.. Highest its ever been, that is with a 10 smooth... I think I'm going to leave it for now and just watch my afr's when it gets cold out....

By the way thanks for all the help...

IMHO, I would change the fine learning rpm and load ranges to something more useful.

now what? How do I do that? Are you talking about in learning view? if so I have no clue how to do that.

If you have the latest definitions, the tables can be found in the "Ignition Timing - Knock Control" section. They are called "Fine Correction Rows (RPM)" and "Fine Correction Columns (Load)".

Done deal, I was super confused. I thought he was referring to Learning view. I changed it to what Mickey has on the first page of the learning view thread. What will this do for me?!

I didn't see that Mickey had a post on the first page of that LV thread... You need to set the parameters so that the load columns are evenly spread across the distributions of load that your car sees. If you hit 2.5 g/rev then I would set the furthest right load column to 2.2 or so and then adjust the rest accordingly. If you have your rev limiter set to 7k then I'd set the furthest right RPM column to ~6200 and scale the rest as needed.

What will it do for you? It narrrows the focus of where you need to make corrections in your timing providing your IAM stays at 16.

Any better? I have not had a single fbkc or flkc since the last reflash. I do believe I'm sticking with it, boost is spot on, I know I'm .10% under in my D column, but I kind of like it do to the fact I'm running a bit lean anyway....

Btw, look at this clip of my log today, notice total timing after the shift... Is that normal? I've been noticing that more and more lately....

That's normal from the handful of 02 and 03 WRXs that I have tuned (not an expert).

It's not knock. You can tell from your FBKC, FLKC, and IAM.

From what I can tell, it helps prevent shift knock. I see shift knock on 32 bit ecus all the time but that timing pull on 16 bit ecus seems to prevent it.

I would prefer this logic because on 32 bit ecus, the shift knock would cause timing to be pulled for about a second after the knock. With this logic, timing is only pulled for a fraction of a second.

would make sense. Also does this, say, when I take off from a dead stop. Not getting on it, just slowly/typically leaving a stop light and I don't quite get the revs right (I'll blame it on the act streetlite) It drops pretty low and goes negative.

I think most of my fueling corrections are 100% weather related. However, it does not make sense, as when its warm out my trims go lean (ECU Adds fuel) when its cold out trims seem to richen up. I'm not quite sure why. None of them get more than 2% out, and thats always the A range. D range never gets more than .25% out. So I'm going to leave it for now.

Thanks for your help!

It's just the nature of the MAF. It has more to do with turbulence and other stuff.

Technically, you are not leaning out. Your MAF is just off at varying temperatures and your ecu is correcting it. You should still be at stoichiometric.

There's a table called MAF Compensation (Intake Temp). There's a reason why this table is in the ecu. The MAF needs to be scaled against varying Intake Temperatures. However, it requires too much statistical data to do this on the street. You really need to do this on a test bench with varying temperature sources.

That's why I haven't touched it even though I know it needs slight adjustment.

Bringing it back. Was working great, its been a bit colder and now my fuel trims have went possitive. A.4 B.2 C.3 D. .10 What why would temperature make that much difference, I had to add .5-1 fuel in higher loads because I was nearing 11.9-1 WOT in higher load regions.

The car is so inconsistent, I can make a perfect pull and 10 min later the exact same situation, but it picks up knock or is .1 or so lower in the max load. I don't understand...
