Question Log: !! Getting -7 Knock with OSECU Stage 2

I just flashed the osecu stage 2 into my 03 wrx. I have an up/dp/borla hush and perrin panel filter. I noticed that my intake air temperature is extremely higher than usual and i'm receiving up to -7 knock in normal driving.

What i did. I flashed stage 2 and then started driving around the block. Got a few knocks and was wondering i should do. Should i try a 3rd gear pull log?

i was really hoping this would be pain free plug and play

Is it really that hot in CA right now? Holy cow.

Your car is not happy right now. I took a look at that map and the timing in that area of the map: 1000 - 2000 RPMs and ~1.4 load. The timing in that map looks fairly aggressive. You're running 91 oct and you're running a few more degrees of timing than I on 93 oct. On top of that, your KC map is set to 0 now your ECU has no choice but to make your KC negative.
My advice to you is to pull a few degrees of timing in that area and see how your car responds. Also, your closed loop AFR is set to 15.1. That tends to be on a bit too high for most people, especially in warm climate states. I would bring that down a bit to about 14.9 or 14.8 and go from there. It might be just a little too lean for you. Start from here and log again. Report back when you have new results. Good luck

EDIT: I just checked the weather and your temps are way off. Los Angeles is reporting 65F right now. Your IAT is reporting 111. That is definitely not right. Perhaps your MAF may need a cleaning. That is all I can think off on that account.

so sad my intake air temp is off.. think it got dirty from the perrin oil? i just installed the perrin panel filter prior to flashing. what does the maf sensor look like? i'll try to look it up tomorrow and see whats up.

i just reflashed back to the stock rom and noticed that my intake air temp is still higher than usual. The maf must have gotten dirty from the oil from the perrin oiled filter that i added 5 minutes prior to flashing. I read a few other threads on maf cleaning and that seems to be the culprit. Question is, do you think just that dirty maf could cause all those problems? only one way to find out i guess

i'll clean the maf tomo with non chlorinated brake cleaner and then try stage 2 again and see. wish me luck! thanks ziggy!

^^^ Good luck. Cleaning the MAF will certainly not hurt you so go for that first and report back. There has to be a good explanation for your issues. Let us know how it goes.

With your mods I'm not sure I'd go back to stock for too long. I'd just modify the Stg 2 map so it's happier in your car. They are off the shelf maps and aren't optimized for different cars in different environments.

I've looked over the stage 1 map for my car and found it to be a bit more aggressive in some areas than I was comfortable with (over 8* of advance in some areas over stock and high target boost values at low throttle openings). I can only image what the Stg 2 map is like. To get you started just do a comparison of the stock and stg2 maps and see where things are radically different and then back them off a little bit.

On your log I also see the KC is at throttle tip-in and low rpm/load. I've seen negative KC values under those conditions with the stock map (although usually only in the negative 2-3 range). From what I've read, under those scenarios some -KC doesn't necessarily mean there is knock. It could be something in the engine bay knocking against something else. However, since your KC values were so high, to be safe back off some values in the Stg 2 map.

Disclamer: I'm a noob at this and my comments are based on my personal, limited experience and things I've read.

The reason why he's getting -KC numbers is because there is no room for adjustment in the knock correction map. In that range, the values are set to 0. I believe the stock map is also set up that way as well. That is fine as long as the base timing in on the money. In this case, I would go with an assessment that if the ECU is pulling timing, it's because it's detecting knock. Rattles can do this sometimes but it's rare. The sounds have to be of specific frequency in order to fool the knock sensor into thinking the engine is knocking.

Here's what I would do:

1. Clean the MAF
2. Pull timing in the stage 2 base map to get the knock under control
3. Log and analyze the results

At this point, you need to get a good, safe baseline before you even start thinking about power. You did not by any chance gas up with 87 by accident? Your ECU was pulling lots of timing.

how mcuh higher are your iat's compared to outside temp during normal 30mph driving? with my normal paper filter, i was getting like +2iat when driving and up to +7 at a red light. with this damned perrin, i'm getting like +10ish iat at 30mph and stopped goes up to +15 degrees. prior to the clean today, it was like +20iat at 30mph. all of this is in degrees F. so cleaning did help a bit, although iat numbers are still higher than stock paper.


by 'pull timing' do you mean to lower some of the values more close towards the stock Base Ignition Timing? which load columns should i modify? here's the 0.44 column to give me an example

The stock ECU will use negative KC if you are lugging your engine. I've seen -8 on my own car at 2000rpm in 5th and 6th gear. I have my knock sensor hooked up directly to my stereo and can tell you there is not even a hint of knock.

The first log probably isn't knock, just you lugging your engine, but the second probably is since the IAM is going down but hard to say. Down to zero!

I also noticed your vehicle speed is going DOWN in the first log at 2000rpm, 5mph, and 12% throttle. Was this up a steep driveway or did you have your foot on the brake or what?

i think thats when my car is in first gear, i'd let off teh throttle a bit and the gear slows the car down. is that what you mean by 'lugging' your engine?

I think you are trying to reply to two different paragraphs of mine in one sentence.

I guess that's you blipping the throttle and slipping the clutch in that first log. It just looked odd.

The KC will go negative when torque load on the flywheel from the transmission is greater or approaches equal the torque the engine is making. So if RPM is falling and you're not just off throttle, say, like slipping the clutch, or using too high of a gear, or going uphill, etc, KC will go negative. This is because of the load. When you are accelerating, clutch fully engaged. I.e. if the engine is losing the battle to speed up even though it is sucking air in and making power, it adjusts timing downward.

Here's everyone's homework assignment. Go log your car in 5th or 6th gear at only 30-35mph. Give it 1/3 throttle. You won't accelerate because the car isn't making enough power, and KC will drop like a hammer. If you nail the throttle to 100%, you might get back up to +0 or +2 KC oddly enough.

It won't do it at 35mph in 2nd gear, and it won't do it in 5th gear at 65mph, unless you are going up a steep hill.

I have never seen a map to adjust this, but I've been testing it on my own car to see exactly what is going on. What I think is going on is there is a acceleration rate compensation map that is injected into the KC logger value for some reason. It is from another source, another map or maybe just hardcoded in. I haven't had enough time to find exactly what is going on, but that is it more or less.

If you are really worried you may consider hooking up an audio jack to your knock sensor and listening in. There are a bunch of threads, search for "knock sensor audio" or "detcans". It isn't that hard to hook up.

^^^ Freon, I've been thinking about hooking up the knock sensor to my aux input on my stereo. I searched around and I keep finding threads that are relevant to TXS devices but no good info how to get the sensor hooked up to an aux port. If you have any threads you can point me to, I'd really appreciate it. Thanks and sorry for a hijack!

sounds very likely.

FYI - here are some possibilities based on some of the OEM crap I've woked on:

1) load-rate based spark retard: Typically, if you have a rapid rate-of-change of engine load in the increasing direction, you can get what is called "burst knock". To preemptively combat this, it is common to pull a bit of timing for a short time on a rapid throttle or load (MAP) transient. More of a problem at low-moderate RPM, so this boxes with what you're saying and makes sense to be included in a "knock correction"
2) active driveline cycle cancellation: most manufacturers feed back on engine speed in the lower gears for manual trans vehicles when you go open pedal. The idea is to smooth out the RPM trace and get rid of RPM cycling that can be caused as the trans/driveline wind up and release. All kinds of (patented) strategies out there, but this would be used primarily at lower speeds and can do "interesting" things when slipping the clutch...

Try google... "knock sensor audio" "knock sensor audio recordings" "knock sensor wav" etc etc. That should keep you busy for awhile.

1st google hit leads you to this page which shows you how to build "det cans".

I had a look at the OSECU maps and they seem to be very aggressive to me, especially for CA fuel. With the amount of knock you're seeing, I'd suggest starting with the stock timing maps and stock boost targets and lower the max WGDC to prevent boost spiking with your stage 2 mods.

after cleaning the maf and iat back down to normal, the knocks are for the mostpart gone. Except at 4.7ish load and 6400rpm. Im working on lowering the base timing in that area now, so it should be good. my am is now stable at 16s too ! thanks all! i'll be updating and be putting my questions up in http://forums.nasioc.com/forums/show....php?t=1175144

Yay for clean MAFs! BTW, I would just stick with the paper filter, then you'll be a lot less susceptible to the MAF getting dirty again.

Cruising one particular street (Henderson NV-Horizon Ridge west of Horizon Drive near the incline towards Stephanie) at ~50pmh in 5th gear, RPMs in the 2000s, load approaching 2.2 as I get into the throttle as I approach the hill:

I've had the IAM shoot to 0 and then settle at 3 with an OSECUROM Stage 1 map where had I already pulled timing from in that area
AND
I've had the IAM shoot to 4 with the stock ROM.

I heard NOTHING. I know knock can be inaudible, but I could have expected to hear something if it was this bad. I've driven the same route several times with the windows up and down and had the IAM plummet with no unusual sounds.

I've posted the logs and the rom here:
http://www.plasmatize.com/osecuroms/...?t=16&start=45

Compared to the original Stage 1 map, I've pulled timing from several areas already because of -KC.

I'm new at this and was (mistakenly I realize) chasing the -KC events and pulling timing there.
Now, I'm going reevaluate some of the 1* pulls that I did in the low load ranges because I've noticed the same types of -KC with stock maps when I take off and under even throttle level road cruise. I once cruised ~15 miles with cruise control at 70 and despite the road being fairly level, I saw occasional -3 to -5 KC sometimes even during slight downgrades.

Did the IAM shoot to 4 right after the flash? Did your car have teh chance to learn after you flashed back to stock before driving that hill?

I've flashed my car with a rom that starts at 16 AM and had the iam's drop to 8 because i was driving around really slow after the flash, not in boost for quite some time. After seeing it move down to 8, I did that 'vishnu reset' trick where i'd keep the boost at about 4psi for like 5 seconds. The iam then jumped to 16 and stayed ever since.

Holy crap.

At 2000rpm and 2.00 load, the "122906 - OSECU Stage 1 r8 - AFR & Timing.hex" map you posted runs 8* more than a stock 05 WRX.

The 2nd map you posted "9 - 010707 More timing from #8 WIP..hex" Still runs 4* more timing than stock at 2000rpm, 2.0 load.

Go back to the stock timing maps. Please. Before you blow a ring land.

If your car is reducing the IAM to 4 on the stock maps, you've got other issues. Post those logs, please.

I dunno, but I think we're learning quickly...

I have done almost nothing at all to my timing map in vacuum from 0-4000rpm. I'm within +/- 1.5 degrees.
