Default Question about Utec

I just recently bought a UTEC from a fellow NASIOC member but after looking at everything I am missing one standoff and the ABC y-piece. Now after calling TurboXS they want 35 dollars for a kit with standoffs and 85 dollars for the y connector. I have an 05 sti with k&n intake and a bosal DP. I would like to run stage 2, do i need either of these parts to run stage 2? I was told i may be able to use the utec to control the boost so i may not need the y-connector. Any help would be appreciated. Thanks.

Are you missing a big brass standoff for the kick plate or the little silver ones for the utec?

With the STi you dont need the ABC so dont worry about installing that. I have stage 2 and can easly hit target boost without the ABC.

Thanks guys, i dont have a boost gauge so i have no idea what boost will be. I will be getting gauges shortly. I believe i am missing the brass standoff.

1.) There are no standoffs for the ABC. There is a flat pience of metal with a hole for mounting.
2.) Ive never seen a stage 2 sti that needs the ABC to reach target boost. Dont even bother installing it even though the manual says you need it.
3.) There are 3 hex type standoffs and a flat metal J bracket that allow you to piggyback the utec on top of the factory ECU. I have never installed the J bracket and dont think you need it. Ive been fine for over 4+ years, running just the 3 hex standoffs and skipping the J bracket.


Just try to install it man... I think it will seem fairly straight forward when you give it a try. If not, ask for assistance in Mid-A. There are a bunch of us who can help you get it installed. Good luck!

p.s. If you are missing the brass standoff and you think 30 bucks is too much search for "standoff" on this site. They ship fast. http://www.mcmaster.com/

Not to thread rob or anything but thought I would just ask since the topic of the ABC is on the table without having to start a new thread ;D

I installed my UTEC yesterday(03 WRX) and flashed it for now with the TXS stage 2 map until I can get it tuned (I am only running a TBE). Stage 2 map says I should hit target boost of 16.5. I did some pulls and data log them it seems to hit max boost 17.4 psi (few times). Might be more of a spike thought because moost levels seem to be in the 15 psi range? Is this because I am not running the ABC?

I planned on installing the ABC and a TXS MBC next week when I get my boost gauge but didn't want to install until I could verify boost levels without having to look over at a carputer.

Also the other issue I had is I got a CEL right off the bat when I hooked the UTEC up. I then also got the three times flashing CEL through some pulls at around 5500 -6500rpm range. From what I understand this is a misfire, I changed my plugs yesterday and tried again andf had the same issue, did the plugs because they were well over due and I thought maybe this had something to do with it. Don' know the CEL yet as I need to go by AutoZone or pickup a scan tool.

Driving the car conservative until I can figure more out. Also should mention no CEL when I was just on the stock ECU. I am using the spark plug mod for the rear o2 sensor and hasn't gave me a CEL for 10,000+ miles.

Now don't flame me for not searching because I have but there is quit a bit information out there about the UTEC I have been reading but it's taking days to sort through the info

Any advice or input is always appreciated

The flashing cell durring a pull is knock. The ABC can be put on if your having problems reaching target boost. It actually bleeds off boost prior to your car reading it so the car thinks its seeing less boost and tries to compensate by giving more boost. The boost spike could be from the boost gain setting. I would suggest you read the UTEC manual it can tell you everything you need to know.

Yeah I had read the manual but there is a lot of information to digest. I am now aware from re-reading it that it's knock with the flashing CEL. It shows knock counts of all sorts under my data logs. One pull it had knock listed as 14 but most often two or three times.

I'll just be taking it in for a tune since all this is new to me and really don't feel comfortable tweaking around with this and blowing my motor.

Well I am new to all this, so here is all that I have captured. I cut and pasted it from the HyperTerminal using word. I am sure there is away to export it but just haven't figured it out yet. Here is what I had:

00772134 4317 +10.6 3.7 95 70 00 rich 105 350.00
00772534 4547 +11.7 3.7 96 70 00 rich 99 350.00

00776534 5420 +7.0 1.5 0 20 00 12.4 0 ECU.
00776934 5027 +1.3 1.8 0 10 00 rich 22 ECU.
00777334 4636 -4.7 1.9 0 00 00 rich 23 ECU.
00777734 4363 -10.6 1.8 0 00 00 rich 23 ECU.
00778134 4345 -10.4 3.1 34 10 00 13.1 13 210.00
00778534 4268 -6.7 3.4 84 10 00 16.4 99 335.00
00778934 4317 -1.6 3.8 98 30 00 18.8 117 350.00
00779334 4351 +5.1 3.8 95 70 14 13.5 94 350.00 <------ this was the knock
00779734 4329 +10.0 3.8 53 80 00 rich 62 257.50
00780134 4438 +12.5 3.5 24 70 00 rich 0 ECU.
00780534 4456 +10.6 2.9 11 00 00 rich 0 ECU.

I'll try to get this better log done it shows about 2 to 3 on the knock on the others but this one was the log that had 14 . I thought if it was knocking that bad I could here it but didn't. Well I have a loud TBE so maybe that's why.
Thanks

youre going to get a lot more help if you use Logger 1 and wrap the text in [C0DE] log here [/C0DE] tags.

but I really hate to tell a guy who has a knock count of 14 to go do it again so we get a clean log.

Next time you are in Hyperterminal log into your utec and do this:


----Step 1.) setup hyperterminal to log
go to Transfer --> Capture Text

I save my log files like this: month_day_year_gear_temp_log#.txt

(example: 3_23_2006_4th_48_log1.txt)

Click 'Start'

Then hit "1" ... this will start logger 1. I then hit space bar to pause logger 1.


----Step 2.) find a nice clear wide road you can do a 4th gear pull.

From a low RPM (low enough that you can floor it without bogging.. 2500 rpms works nice) ... hit the Space Bar again to resume logging, then FLOOR IT TO REDLINE! ....

After you let off hit the space bar one more time.



----Step 3.) Check out your log.

Pull into a safe parking space. Go to Transfer --> Capture Test --> Stop.


Is your exhaust catless? Even so, the rear axle back is restrictive so if I were you, I would use the stage 1 map. Now it's hard to tell but it looks like your knock happens right after a shift.

Some of us (myself included) have put timing in our 0% column and that helps for shift knock. (if that is what you have... hard to tell in that log)

If you think you have shift knock, you can try putting 18 in your 0% timing column for 4750rpm - 7500rpm.

Hey thanks for the advice and help, appreciated . Tomorrow I'll do what you have said and get a clean readable log. That particular time (14 knock count) seemed unusal most other times I have seen knock of two or three. I am running 92 octane gas and if I understand right these maps were made for 94. So maybe that isn't helping.

My only other mods besides the Utec are a catless turboback (Helix DP and Invidia catback). I have been driving my car real gently and have thought about taking this back off. I realize these are base maps and probably need further tuning but don't have the wideband 02 setup, nor know anything about doing that. I was really undecided about EM and couldn't decide between the AP or the Utec but decide to give this a go. Hopefully I can learn how to do this and make it work.

I am going to log the stage 2 and then take your advice and switch back to stage 1. I agree about the timing of the knock was suprise to see that much with that low of a boost reading.

I've had a knock of 2 and 4 and one of 11 that I've logged...

this guy had a 14 how high does it go up... and how serious is it to have a 2 compared to a 14?

I didn't find a scale in the documentation, but I still need to read a lot.

O.K. guys I was able to do a run on the way home tonight from about 3000rpm to 100+ MPH. I stopped due to the fact that the CEL would just keep flashing, better to shut it down than keep running to redline with knock. So here is my log. This was using logger 1 and I rea;ize my TPS needs to be calibrated but right now am more concerned with the knock.

I have only posted the info from before the knock starts to occur to when I let off and the knock stops. No count of 14 at all so I think that was erronious but who knows. This was a 4th gear pull started at about 2800rpm.
Let me know what you think. I have flashed the UTEC back to stage 1 map for now. I am not hitting target boost right now but am not running the ABC but that's o.k. because the knock has to go before I want to hit target boost

BTW thanks to AaronWRX who helped me learn how to capture the log

Try reduce the timing at 70% to 100% from 4750 point to +18 deg, add 0.2% fuel on knocking section.

I used to have this problem till I lower the boost setting. surprisingly ,the car is getting boost past 16psi yet knocking free. However I am running Open loop boost setting, with Boost solenoid dutycle maximum at 75

Your ECu is running at +12 deg but you are pushing it to +20deg...not all zone of rpm could take +8 deg advance than ECU timing.

you are getting good advice here. The column right after "rich" is the timing your ECU is trying to run. Even though the utec can't keep a long term history of knock your ECU can. And from looking at things I can tell that your ECU is VERY unhappy. It has seen knock in multiple areas.

I have no idea why turboxs no longer provides 91octane base maps like they used to. You should call them and ask them if they have one.

I'm not sure I would add fuel at this point. I seriously doubt you are running too lean. Your knock looks timing related.

Now if you look at your 4th column from the left that is the timing your Utec is trying to run. See how the knock count of 3 keeps coming back over and over? Well the utec will take away timing when it detects knock for a few rpms (notice the 12's?) then when the utec thinks the knock event is over it goes back to the 20's... and you get knock again.. back to 12's...

Octane is def your problem. Def remove timiming the way described ^^^. See if that fixes you. If it seems to correct the problem reset you ecu and drive around a couple of days and see if your ECU's timing starts looking more health.

It's too bad you can't run more boost. good luck.


edit: I re-read my reply and noticed it comes accross non-shalant and I don't want to make it seem like what you are seeing is not a big deal. You were right to take your foot off the gas. Your motor will not survive if you don't take care of it soon. I'm not saying that you yourself arent capable of fixing this but it wouldnt hurt to reach-out to a local utec guy in your area to go out on a few runs with you.

Also calibrate your TPS, you're never reaching the 100 column.

That's a LOT of repeated knock. Stop driving your car hard if you're getting knock like that. If you see the light going nuts like that, BACK OFF THE THROTTLE! You should've taken your foot off that first 3 count.

At a glance I would say your timing is too hot. Probably because you're in the 70 and 80% load columns. I'd go and either lower your "max boost for tuning" value (probably set to 18 or 18.5psi), or go through your map and move your timing to the left a bit. Get your 70 and 80 load column timing values more like what you see in the 100% column. But you never know without a wideband, your AFR may be way off as well.

As said above, the ECU is running stupid low timing because it is getting lots of knock as well. You really need to get that tuned up. Badly. If you aren't sure what you're doing you may want to just spend some cash and find someone to tune your car to get started before you pop your motor.

I've also never needed the ABC to hit target boost on my STI. I have since switched to a new boost solenoid, which would never need an ABC in the first place.

The ABC does not make the car "see less boost". It bleeds off extra boost before the wastegate. It is like making your boost control solenoid flow more. Still kind of the bandaid approach. I'd much sooner recommend a 3 port solenoid, which never needs any restrictors, MBCs, ABCs, or other misc BS to work well. And they're dirt cheap...

Thanks guys for the good responses it's really good info. I actually stopped driving it hard after I logged that run. I Agree I should had let off but I wanted to get a good picture of what I needed to do.

Well I drove the car easy after that and decide a few days later to pull the Utec and sell it My car is my daily driver and I have been good to it over that last three years and oit's been good to me and I didn't want to screw that up

I decided to pick up a AP since I really didn't have an AFR, Wideband or anything else to tune it nor the right knowledge. I would have liked to learn but maybe another day as I don't have time right now.

So I am just running the AP now and will get it protuned. I liked how the Utec would listen for knock you don't get that little feature with the AP. So hopefully it's not knocking anymore.

Thanks again for your response even after since selling the Utec it was nice to read and gave me a good idea of what the ECU was doing.
