I'd say that's the classic knock-after-shift described in mick-the-ginge's UTEC tuning guide. I took Mick's advice and remedied this problem by locking down timing and richening AFR's in the higher rpm and lower-load range. Specifically, I set timing to 14deg in the 0% column from 4500rpm on up, and richened quite a bit the 10 - 40% load sites from 4500 on up as well. Hope this helps.

Steve.

PS - you can download the tuning guide from wrxhackers.com

yes, looks like too quick/severe of a timing jump. what's your utec timing map set to for 4500 rpm 70 column? by the time it's logged the utec has already pulled advance.

yeah, what he said.

also- think about smoothing your timing transitioning between these load sites

4500 - 10-100%

your boost is coming on very strong very fast. if the transitioning between load sites isnt fluid, it might knock with too big of a change.

Cool. I'm trying to break down these replies. A year after I've had this UTEC and I still just don't get it. Or maybe I'm too scared to actually touch the values
Maybe I'll read the couple tuning guides I have again.. Thanks.

whatever you do, DON'T be afraid of tuning out knock!

generally, more fuel and less advance is always a safe direction. don't be afraid to use that sucka and get into it! keep logging and post 'em up here and folks will offer their experience and guidance.

I've been looking at mick_the_ginge's tuning guide. what's this program he's using to change values?
How important do you think it is that I update my UTEC?

Click Here to download UtecEdit(map editor). It would probably be best to update your utec software. You might wanna think twice before puting a timing value of 14 anywhere in the 0% column. The point of locking down timing during a shift is so the timing doesn't jump. Having smooth transitions in the timing map helps this. The reason they say to lock down the timing with a specific value is cause sometimes the ecu will get really eratic with timing, and this has been known to happen during a shift.

Here's your little knock event. To start out, usually at a given rpm, lower load sites have higher or equal timing values then higher load sites. So, at 6000rpm in the 80% column, you run 28 degrees of advance, the 70% column should be at least 28 degrees(even though it's 25 in your log) or the value in the 80% column should be 25 or lower since the 70% column is 25 at that point. Then think about filling in the 10-30% columns with timing values other then ecu(everywhere), and the same thing with the 0% column above 3750rpm. Trying to make nice transitions........ Another thing to think about is that it looks like you've knocked a ton up top. An ecu timing value of 19 at 6000rpm is abnormally low. Ya might wanna think about removing a degree of timing from the whole map, and resetting the ecu. As always, this is just my opinion and I'm no expert.

here's a little look at one of my timing maps, so you can see how I went about changing my map to make everything smooth(especially shifts)...

Thanks aot man. That's one hell of a reply. When you say, "Then think about filling in the 10-30% columns with timing values other then ecu(everywhere), and the same thing with the 0% column above 3750rpm." where should I start with these values?
and
"Another thing to think about is that it looks like you've knocked a ton up top. An ecu timing value of 19 at 6000rpm is abnormally low. Ya might wanna think about removing a degree of timing from the whole map, and resetting the ecu. As always, this is just my opinion and I'm no expert.
How safe would you say that is to remove timing from the whole map?

How safe would you say that is to remove timing from the whole map?
1) Just like I said with the 70-80% columns. the lower load columns at a given rpm point should generally have an equal or higher timing value then the higher load columns. So, you could just fill the 10-30% columns with the same values as in the 40% column, or maybe a little higher if you want. The 0% column(above 3750rpm) should be somewhere between the number in the 100% column and the number in the 10% column. As you can see in my map, the 0% column is generally 1 degree lower then the 10% column in the rpm range after where I'm inputing the number(if the 10% is 22 at 5000rpm, the 0% is 21 at 4750)....

2) Very safe. The only thing that might become a problem are your egt's. As long as you keep an eye on them and make sure they don't get too hot, you should be fine. You will probably lose some power from removing timing, and probably don't need to remove timing from the whole map. Removing timing from the whole map just makes the car less knock prone all around. The reason I said to remove a degree from the whole map instead of just high load areas(like the 80-100% columns) is that I figured removing timing from one part of the map could make the timing jump between that part and a part where the timing wasn't removed. Removing a degree from the whole map keeps the transitions the same as they were b4.

One thing about filling your 0% column with locked values(above 3750rpm) is that the egt's might also get hot if you're above 3750rpm and just cruising. Make sure to watch the egt's and you will be fine. Chances are that you will not have any problems with the egt's getting to hot from doing any of the above, but it's good to keep an eye on it. If you find yourself cruising at and above 4000rpm and the egt's get too hot(which probaly won't happen), either accelerate hard(to make open loop fueling kick in), or shift into the next gear or decelerate(to make the rpms drop below 4000).

peace

This makes no sense the OEM ECU does NOT become eratic with timing sometimes. The ECU is doing what it was told to do, in between shifts the ECU has a set of learned timing values that is uses in between shifts which are taken from sensors on the engine. With the values it reads in, it then adjusts the timing accordingly and stores those values in the learned timing values. Though now that the UTEC is interfering with the way the OEM ECU was designed the OEM ECU is getting garbage in. Garbage in garbage out...

Locking down the UTEC timing fixes this problem by overriding the stock OEM ECU timing values therefore eliminating the problem. Though now, the OEM ECU has no control of safety for the engine. So now the UTEC takes full control of the safety of the engine.

Hey Hippie. I think I did everything you said but I just wanted to see if you would take a look before I load it back to my UTEC.
Here's a pic of what I did...

How's that look? Does it look safe?

please take some timing out of the 80-100% cols. they should be LOWER than the 70% col.

OK. I'm trying to follow a few different people here. I will try that though. I don't know if you would need to see this along with my log but here's the map before I touched it.

THanks for the quick reply though. Appreciate it

Should I do this all the way across the RPMs?

yes.

more boost = less advance. ALWAYS.

i'd take another degree off the 100 column.

also you are running a lot of advance in the 4-5k range, especially from 70%-100%. the engine won't take much there (and you don't really need it anyway). ie mine is around 20*.

I really appreciate your help. That makes sense too.
I get knock there sometimes too when going through the RPM band.
If I change the values in the 70-100% at 4-5k range, does that mean
I would have to smooth it all back out like I did originally?


On a side note, if I'm not running lean and I'm not overboosting,
wouldn't that pretty much prove that the knock problem is coming
from the timing?

What ride said.... Uh, who set your timing map in the first place? To me, it looks like a normal wrx would have serious problems all over the place using that timing map(on 93 octane). It would probably be best to start with a txs base timing map and adjust from there. gimme a minute and I will post a timing map that I'll make off the base stage two map.....

In case I forgot to mention that.

And the base of the map came from WRXHackers download section for stageII+uppipe.

Most of the maps are for the older utec software(3.1). Not that the timing would be any different, but that map very very agressive(if not just weird)...... Here's what I came up with off the stock map. I added some timing in certain spots, evened it out in the areas where I thought it should be. This is a very very conservative timing map compared to the one your were using(watch egt's and make sure they don't get to hot if you use this). If ya want one a little less conservative, just let me know.
