I've never tuned a car that had perfect MAF calibration or VE tables 100% accurate. Outside of idle, my fuel LTFT is generally 5%. Idle has been fixed though where it was running 12% at most times and my car has stopped smoking like....a smoke stack....on startup.
Are you still running an E30 blend? Your Stoich Scalar may not match your fuel. I noticed with my blends my match was not perfect, and that caused me to be off until I zero'd in on it.
MAF transfer and VE tables from the factory should match your car fairly close, enough to where the KAM adjustments can hone in on the last bits in my experience.

Perhaps I've just been lucky in that my Focus hasn't required any changes. I can't speak to any previous cars I messed with, as I usually had swapped heads and cams, which has a dramatic effect on VE.

Nope, on my second tank of quality(crap) BP 93. Outside of idle my fuel trims are decent and well within the typical deviation caused by temperature and fuel differences.

Sorry I've been off the radar lately. Broke my foot a month ago and haven't been able to do much with the car and have been busy trying to keep an income rolling in for myself until I can go back to my day job.

I'm still around though.
 
It's been very eye-opening reading through this thread and should hopefully give me some good points to work from when I begin self-tuning mine within a month or so!

Lots of good info floating around here and on the rest of the forum too.

Also, I just got my cast off my foot. Going back to work feels good. Hopefully I'll be able to get a few more good revisions of the tune in before winter hits.

Yeah there is. I work for Ford at their Dunton Technical plant in the UK doing this sort of stuff every day, but never ventured in to doing it on my own car. I'm really looking forward to getting started on the ST!

Sounds good, I'm looking forward to seeing some more logs etc

Well now that in back to work and healed from my injury I've been able to be mobile enough to start fooling with the car again...

I fire up ATR today and get an update, plug in my AP and get an update... Looks like it's time to rebuild my tune based on 3.00 so I can use these new features.

By the time I got the first new file flashed, it was too chilly out for any logs, kept ripping the tires loose in 3rd gear and wasn't about to attempt a 4th gear pull anywhere near this area.

What I'm trying to do is go to the drag strip this weekend with a few buddies in Sunday, assuming the forecast doesn't get worse. I'd like to use the track as a place to get some logs while going at it hard.

I'm also interest in attempting to tune boost by gear and this would be a great way to test that out.
 
Sounds good!

Should have my AP and ATR very soon, so I should be starting self tuning mine soon :D

I'm going to be in Chicago to see Ace Frehley in November

Have you enabled the octane adjust tables in your tune, was cruising yesturday and noticed COBB zeroed out the whole OAR table in the stage 1-2-3 tunes

But retains it in the stage 0 file

Yeah!!!! I'm trying to go to that too but i haven't gotten my tickets yet because i just got back to working and money is extremely tight right now until i start getting some checks. But for sure I'm gonna try to go. Ace is my dude!

No I haven't... I'm gonna have to take a look at that in the ATR software... That's odd.

Also, has anyone had any success in 1st and 2nd using boost by gear? I've got 1st and 2nd turned down quite a bit, I see the ECU dialing up less boost but damn I'm still spinning these tires! hahah
 
I use the tq limiters in 1st and 2nd with a lot of success

The OAR timing table is under borderline> BL comps I believe

I was shocked to see that essentially the whole adjustment ability of the OAR system was basically turned off..

I changed mine to be able to play with 3* of advance or retard and made it require less knock to begin trending positive I'm hoping this will make the OAR dynamic and adjust well based on fuel quality like stock

I'm going to have to keep playing with the settings until I find something that doesn't spin the nuts off the damn thing. Then add a little at a time until it starts to? I guess? I dunno.

I think I cut down the tq limiter in 1st to like 150, and then allowed like 200 in 2nd and then third is wide open
So you're using the Torque limiter tables


As opposed to the WGDC multiplier by gear tables?

I have boost by gear set to 40% in 1st gear and 80% in 2nd gear. I haven't launched much, but it helps a bunch.

I've got mine set to .25 in 1st and .50 in 2nd... I'm gonna have to give it a good trial somewhere and see what it does.
