Default Another UTEC ?, Got Mine:-)

Ok, UTEC, VF-34, Fuel pump, and all the other goodies are in. Car rides great and I'm VERY impressed. Thanks Phil for the favor by the way!

Now, on too the question. I have noticed some knock on the conservitive map so I need to start tweaking a little with the timing and boost values for my 93 pump gas. In closed loop the car runs like a dream, open loop does as well but I won't get on it till I can tune out the little bit of knock.

I noticed in the installation manual it referenced a WRX Tuning guide. Where might I find this so that I don't inundate everyone with questions:-). I've logged my knock events on two occasions and haven't gone back to those speeds since. After looking through the timing and boost maps I am a little confused as to where I should begin my baseline map tweaking. Obviously I should probably add gas, reduce timing, or boost, or a combination but I am a little confused as to the constants used in the maps and which to tweak first.

Anyone have any suggestions?

Thanks,

Shawn

will the UTEC eliminate the concern of getting a cel like a full stand alone does? Does it also eliminate the need for a boost controller?

Shawn,
As i posted in another thread, we are still working the bugs out of our maps since we are now dealing with a much larger sample rate and different fuel qualities across the country.

What I suggest as a start is to start with your fuel map. Block select (shift + asdw) the area of the map that you’re getting slight detonation in, and then multiply (ctrl-u) that figure by .9 or .95 to add a bit more fuel into the map.

If that doesn't work pull a degree of timing out of the same area.

You'll need to play with this just a bit to get it spot on.

I do have one other question for you though, did the CEL flash and the car feel like it pulled timing when you got the detonation? Did you "hear" it? I think most people are going to be very surprised how much more sensitive the UTEC knock control is than their knock-link. We have recordings of cars that detonate and the knock link is still well into the "green zone"

You can turn the CEL off with the UTEC, and the boost control works quite well even in its "open loop" state. The closed loop control will be back soon.

"Open loop state" meaning that it works like a ebc or mbc?

Open loop = no feedback. Some EBCs and all MBCs work this way.

Closed loop = some sort of feed back loop in the system.

Thanks Nathan and Jorge (I Vote for a tuning forum as well ). Not only would this be a great forum for the UTEC, but other systems as well, also a great place for a DeltaDash repository.

Nathan,
Yes, the UTEC pulled timing and the cell flashed perfectly. The first run had 2 det's and the cel rapid flashed twice, car actually started responding the the retarded time before I visually could see the cell. The log for that run showed 02 knock count at that same RPM count as well.

2nd run, 07 knock count , utec pulled timing hard, never heard the detonation. Log's showed the 07 knock event at the proper RPM as well. Cel went balistic on that run and that is why I won't run my car WOT until I tweak it out some.

I will admit this, and this is my own fault/stupidity . I have everything installed BUT the STI injector's. I KNOW this is why I am having this problem, at least I'm pretty darn sure it is. My car is in pieces as I type this and the injectors are going in. Then I'm off to make some runs.

To answer your question about the knock link, mine is now for sale. I think that sums it up. The UTEC is great, the Cel flashing on startup to tell you what map your on ROCKS, and the knock detection/correction is top notch. No need for the knock link for me, I'd rather spend that on something else now:-).

And another answer to questions that have been asked on other threads. The transition between open/closed loop is transparent to me and I Auto-X this car, thats the reason I bought the WRX in the first place was to race it. UTEC control seems far more in tune and transparent than the Unichip. I did some DD logging last night and my EGT's are PERTY in any condition, no more of that partial boost issue.

I can't wait for the remote map switch!

Thanks guys,

Shawn

PS, Nathan if you have a beta copy of that tuning manual feel free to send it my way at shawn@bowen.com. I will be playing with this thing getting it dialed in OR I am going to take a road trip from Atlanta to you guys to get it done before the race in FL on the 11th if I can't get her dialed in safely.

I just re-read the thread...

A: what boost are you running?

B: what map are you running? What is the title on it?

Whoa.. wait a minute. The CEL FLASHES when you get detonation!? That is SO COOL! I was just getting ready to hack into my knocklink, I guess the only hacking I'll be doing it taking it out of my car

I run the knocklink in combination with my bum and ears to dial in the knock sensativity on my car. Since different engines produce different harmonics (valve train, etc) I'm slowly dialing mine in. So don't ditch it yet.

As they come from TXS they are very paranoid (which I'm sure no one will object to), but you can adjust that sensativity in 1000 RPM increments, so it's nice.

Jorge vf30STI map setting one, map setting 2 is vf30stiinj. Those are not the exact map names, but close. Dude, these injector's are a PITA!!!

Anyone know if they should still "slightly" turn once the fuel rail is put back on and tightend down? Also, do I have to put that darn green bracket back on! I was thinking about just rerouting the crank case vent since all that bracket seems to do is add weight, get in the way, and route the Crank Vent.

Oh, and 17PSI with the ABC cranked ALL the way down. Defi link and DD confirmed I hit 17 as well.

Injectors should still be able to turn - if they can't you've pinched a gasket. And take those green brackets and throw them away!

Shawn,
Simply put, your lucky that the utec knock control is so good as this map was designed for STI injectors. We've had customers who have done the same thing with a unichip (put a chip on that was mapped for larger injectors without installing the injectors) and blown their motors to bits.

Yeah, I know Nathan:-). All is well.

Also, I found a good post on the injector installation http://forums.nasioc.com/forums/show...jector+install .

Thanks for the heads up on them wiggling being ok. To H*** with those brackets, they are trash.

I have a different problem. I could buy a UTEC tomorrow and not even blink at the price. But I have to wait until the lease on my pickup runs out in February before I can buy a WRX because my driveway is full!

Can anyone appreciate how frustrated I am right now? Other than my long-suffering wife who hears about it every day, that is.
