1. As you change the ABC, you will need to change the CLB values as well. The comment regarding "safety" is probably not relevant, as this is more about CLB control, not "safety."

2. I'm interested in this as well. I don't recall reading that ABC opening is directly linked to temperature related boost variability.

Methinks boost tuning has multiple strategies that work, each has their advantages and disadvantages. Until TXS comes out with some form of temperature compensation, we'll just have to pick a strategy and adjust accordingly.

I can see a direct correlation between the CLB values and the BCS % use. I was pondering about your theory of not maxing out the BCS, which is reasonable, and thus I think I'll keep my values between 70-90 and just mess w/ the ABC. I figured since I've tested w/ 5 turns out that I got 15.5psi+/-, thus it can't be too far to obtain 16-16.5psi just by turning the ABC out more. I did a quick test and I can go as far as 10 turns out if necessary. I'll do some logging tomorrow and see what psi I get w/ turns out and go from there.
Right now I know w/ the current CLB vales of -100 from the previous ones posted I'm only utilizing the BCS 1.3% more than 70-90 since my values in Log 3 are 70-90 from 3250-5500rpm+. I'm sure turning the ABC will allow me to obtain 16-16.5psi before the 10th turn, somethign which I hope I will not have to use.

It seems like w/ the ABC @ 7 turns out and the boost values dropped -100 from the beginning boost values, I'm hitting the mid 17+psi which is "not" what I want. However if I look at Log 3 it's having this problem around 3500-4750 so I just dropped the boost values another -25. The BCS seems in the middle range which is what I've been trying to do since the original post about the BCS. Technically I would increase the boost values from 5000-redline rpm too or it it better to run 15psi around 5K rpm and let it die down till redline?

Everything seems fine as boost is between 16.1-16.4 however I did have a few spikes of 16.8-17psi. All of this was done at 39F degrees. I also got knock in a 2nd-3rd run w/ boost being fineat the 5000 rpm point? I've adjusted the boost map: 4250-4500rpm went from 275 to 270 and 5000rpm went from 300 to 390. Do you think it's necessary to adjust these two sets of rpm points or should I let it go? I know that sudden boost spikes will cause knock so I'm trying to stay under 16.5psi all 90% of the times.

Is a good assumption to have 16psi average w/ a max boost of 16.5psi, thus I could run more timing?

Not necessarily.

I'd be really careful hitting 17psi on pump gas without tuning fuel. Even then, I'd be really careful hitting 17psi on the stock turbo. It can be done, but it's just not efficient. Pull some boost out - run 16 perhaps. Remember, when it's colder, the air is more dense. When the air is more dense, it's holding more O2 at a given boost level AND flow rate boosting your AFRs.

Also, don't tune for MAX boost in 3rd. If you do, I can practically guarantee you will knock in 4th and 5th, under higher loads. 17psi in 3rd can easily be 18 in 4th.

Since you're seeing knock, the last thing you want to do is add timing.

I meant ... I do NOT want to see more than 16.5psi at any time. I can target 16psi in "4th;" I've beeing tunning all of my boost values in "4th" from 3K-5.5K rpm +. I've seen 17psi in cold weather ... 25-35 degree however it's only in a certain range. I can lower the CLB values. I think I'll try to hit 16psi and no more than 16.5psi at any time including 20s degree weather.

That's a good plan - tune for that, get det free, and then tune from there.

Det free is the key, of course, you REALLY don't want a cylinder to let go.

Made this a sticky....Plan on some cleanup of this forum soon...
Enought of....UTEC this ...Utec That...How do I tune a UTEC....just so you guys know.....FAQ's are coming.. so this forum can be worthwhile to nOObs and experts alike....

Thanks

Bill

Excellent idea - it could definitely use some cleaning.

Lots of handy UTEC info in one place would fix lots of questions. Now all we need is loaner WbO2's in AutoZones nationwide.

1. Thanks Bill for making this stick. I'm hoping that my "million" questions will help someone in the future.

2. I just spent another 1.5hrs doing some more runs. I've changed my target ... I'm now shooting for 16psi w/ a max psi at 16.5psi; thus the psi range will vary between 15.7-16.1psi w/ spikes at 16.5-16.8psi. All of this was done at 35 degrees however if CLB works as it should; I should still see similar results during higher temperatures. I've been thinking more and more and I can see to inverse effect of "either" more timing or higher boost. I can see 16psi from 3500-5500rpm and of course it's not consistent. I'll post my CLB values tomorrow at work when I do hopefully my final run to confirm my boost values are correct for 16psi.

1. These are two runs which I did this morning to work. It's 28 degrees however "feels" like 20s according to the weather channel. It seems like the most variant occurs between 4254-5250 rpm; if you look at the two runs the first run always seems to have a "higher" boost spike than the second run. This seems consistent per my "many" runs during testing.

2. I'm running 16psi @ 3500 - 5250 rpm then 15.5psi @ 5500-6000 and finally <14psi till redline. I'm trying to target 16psi w/ a expected variance of 15.5-16.5 psi. I'm confortable w/ these numbers since I know it is "cold" outside. Do you think it's necessary to fine tune lower the boost values even more in the 4250-5250 rpm range considering the fact that it's cold outside? I could lower the boost values @ 4250 from 80 to 75 and @ 4500 rpm from 70 to 65?

3. The BCS cycle are between 50-90 which is fine as compared to the previous 133. The boost values which I posted are from 3500-6000rpm.

4. I just hope the CLB does what it's supposed to do when it gets "warmer."

When it get warmer you may need to make a boost map with slightly higher values.

I'm really surprised you don't get more spiking with your ABC out 6 turns. I've always been advised to only turn it out 1-2 turns and then tune the boost map from there.

When I first started in CLB ... I was tunning the CLB values w/ the ABC @ 1.5 turns out. However my BCS was maxed at 133 which someone suggested was "not" a good idea. Thus I first adjusted the CLB values to between in the BCS range of 50-90, then adjust the ABC to obtain 16psi, then finally made small adjustments to the CLB values. Also CLB is "supposed" to NOT be affected by temperature changes thus I should still see 15.5-16psi when it gets warmer.

What about your first run of those three? You were over 17psi for a lot of it. You got 3 knock events in the cycle at 5300, with no shifting or throttle modulation at all.

Rather than open the ABC 6 turns, you might want to try adjusting the wastegate actuater arm. There is a c-clip you can pop off, and then turn the arm to tighten it. Search on wastegate flutter, and spot the really long thread. Nobody mentions using this solution for your issue, but your boost looks really inconsistent. You can probably tighten it a couple of turns and close that ABC back down a bit.

I wouldn't want to drive my car if I knew it would det somewhat seriously on 1 out of 3 runs.

Good luck...

I've actually heard that the ECU reflash fixes some of the knocks in the higher rpm range. I'm assuming the knock would be fixed wither w/ that method or adjusting the A/F on a dyno w/ a WB O2 sensor. It onlys happens in a certain range and if I go WOT in 4th starting in 3.5rpm. During my normal daily driving I get "0" knocks ... if I get aggressive which happens many times, I many get knock but it's because ofthe A/F ... at least that's what I'm puzzling together. If I continue to get knock in normal WOT "after' tunning, then it'll be a problem.

Well, as stated several times before, you need to get that fuel curve slammed out. I'd pull out a pound of boost just to be on the safe side until you do.

If you find a tuner or a friend with a WbO2, you don't need a dyno to do that. You can road-tune the fuel-curve pretty darn well, especially at stage 2.

Or, you can buy a decent WbO2 for $300 - less than any reflash!

Seriously, just look at the cost of the time you've spent on this - it seems like tens and tens of hours.

Not to mention the cost of an engine tear-down if a ring land lets go on you. Don't go there, if you can help it.

I'm running det-free with great power on a UTEC alone - no reflash required. If you've already spent the dough on a UTEC, why would you consider a reflash, especially at stage 2? Or are you talking about a Subaru of America recall-type reflash?

What it comes down to: you won't be able to feel a half-pound of boost. Air is denser at 30F than 50F than 70F. 17psi at 60F is NOT the same thing as 17psi at 30F. Much more O = leaner AFRs, with the same boost and everything. Tune safely if you want that car to last. And tune fuel before doing anything else.

1. Yes, I've spent hour and hours learning about the whole ECU tuning. It's actually quite fun and educating.

2. Yes, I was referring to the "free" Subaru ECU reflash.

3. I figured boost was independant of tuning the A/F, it should still remain the same? Also the car should run "leaner" at cooler temperature since it's more dense. Thus the reason for the lower boost values so if I'm shooting for 16psi in cold weather it should be even safer when the temperature increase.
