I do...it's in the little instruction thingy it comes with. To enter calibration mode, press the button fairly rapidly four times. When it is ready, I think it'll blink once. You then let the car sit at idle and press the button once, and it takes it's recording, and it might blink once when it's done. You then hold the engine at 1/2 of redline (3500 rpm for sti) then press it again. You then hold the engine as close to redline as poss (use second gear and freeway on-ramp, check oil before going out) and press the button again.

If I remember correctly, the light flashes green while it is recording and then blinks amber when it's ready for the next one. Also, it is my impression that you can drive however you want throughout the calibration process, you just wanna be @ the set-points (idle, half-redline, redline) when you press the button. Also, the car must be fully warmed up for it to work properly.

For sensitivity level, press button 3 times to increase, 2 times to decrease...or maybe the other way around. Either way, you press the button two or three times, and it will blink a number of times related to the level it is at...1 being the most sensitive. To test, free-rev the engine...if it blinks on its own while free-revving, it is likely too sensitive. I have mine on 3 or 4.

Last but not least, if it is installed properly, when you start the car, it should blink red, yellow (amber), then green...that let's you know it is recieving the knock signal.

Ahh yes, to set shiftpoint, hold the button down till it blinks or turns green, then press it again at 1/2 the level you want it to go off at. So, if you want the shiftlight to go off at 6000, press the button at 3000.

So you don't set the knocklite by just free-reving the car huh? Interesting. I have been getting quite a bit of knock activity and I have a hard time believing it is accurate right now. I think it might be set too sensitive.

if your car is not tuned for your gas...that 91 california crap may be hurting u. i'd try to recalibrate with load on the engine...it makes it a lot easier to hold the engine speed steady while it records the sound. (a knock sensor is basically a microphone)

also, perhaps you could throw in a few gallons of 100 octane and see if that reduces it. If u get less lights with higher octane, then u know the problem is not the light.

Yeah, if only race gas were easy to come by down here...

hmm...I know there is a 76 with 100 octane way up in Fullerton. There's gotta be somewhere around you that has race gas. Often motorcycle/moto-x type shops will have 5 gallon drums of race gas.. VP has a distribution center in Wildomar (Murrieta/Temecula area). Gives ya some options.

For you guys who installed this with the bosch knock sensor (P/N 0-261-231-006), does it come with wires or do you just solder the power and signal wire to leads on the sensor?

And regarding the shielded wire, if it was that important why didn't TurboXS supply the Knocklite originally with one? I agree it's a good idea and couldn't hurt...but has anyone had an issue installing the Knocklite as recieved?

I ended up having mine installed as recieved. So far, I have been using datalogs and the light to determine where to set my sensitivity. So far I am all the way up to 7 of 10 (1 being most sensitive) as I have been getting false readings. The light was showing signs of det on more sensitive settings when in reality quite the opposite was happening (ECU advancing timing during WOT). I would imagine that a shielded wire would be much more accurate. I am tempted to run very slightly lower on my octane (91 instead of 92...I believe that is a 10 point drop, correct?) in order to induce some det during a log and compare with the knocklite.

Hello,

My knocklite arrived yesterday and I'm getting ready to install it in my 2002 WRX. I don't have a separate knock sensor (I'll probably add one later) so I just want to wire it using the stock sensor for now. In one of his original post Jarrad mentioned that he did all his wiring for his LGT at the ECU. I assume he meant he got the power and ground taps there as well.

I've studied the ECU wiring diagram for the 02' WRX located on North Ursalia's web site (Viewable here) .

My plan is to run all the wires to the ECU and tap the following wires for their respective function:

ECU Connector - Pin# - Content
B135 - (B)9 - Supplies 5V power to several sensors
B135 - (B)4 - Knock sensor signal
B136 - (C)9 - Engine speed (RPM)
B135 - (B)19 - Ground (Sensor)

I just want to confirm with you guys that have installed the knocklight before that what I plan to do will not interfere with any of the other ECU or sensor functions, sensitivity, or accuracy.

As far as grounds go would it be better to use a chassis grounding point or tap one of the ground at the ECU?

Any suggestions, comments, or ideas would be appreciated.

Thanks

I'm replying to this thread on NASIOC because I find little info on the Evo boards in the UK or US.

I bought one of these off Ebay and installed it (and then removed it!) yesterday. Using the stock Evo sensor with working RPM connection, I calibrated with free rev, or under various levels of boost and I could not desensitize it enough to stop it lighting up at high revs when there was no knock (as confirmed by det cans).

I've tried to sell it, but after reading a few things I wondered if I should try a Bosch knock sensor.

Comments? I was all for going back to a knocklink with Bosch sensor as it is the devil I know from the Subarus.

John:

The stock sensor is basically an improved copy of the Bosch. They internally ground one side of the sensor through the bushing, so you only need one wire (shielded) back to the ECU.

oops. I saw Evo, but thought Subie. Got a pic of the sensor?

Hi John, no pic of the sensor, but I tapped into the only knock signal wire at the ECU, so it must ground elsewhere. It was a shielded cable with the shield unterminated under tape as it came from the factory.

still don't see a verifiable pic of a corresponding location to mount a bosch knock sensor that comes with the tuner pro for the wrx?

I finally installed mine last night with the shielded knock wire. Maybe it was my choice of grounding point for the shield (one of the bolts for the kick plate) but the ecu threw a CEL and the knock lite started going nuts at idle. I checked my RPM and knock wire to make sure I hasn't cut them since I ended up using wire taps. Everything checked out okay. I then removed the shield wire from the ground and plugged the ECU back in. Fired the car up and everything was fine. I had to back down the sensitivity to 2. So after going through the trouble to replace the ground wire with a nice shielded wire... I ended up not connecting the shield to a ground afterall.

I've had mine for a while now and I really like it. Apparently, I get occasional, light, unaudible knock if I don't use a bit of race gas...never would've known without the light. It's very likely a lot less than a stock car gets, and it could be a misreading, but I tend to play on the safe side. It's a good way to tell how much race gas I have to put in.

Since getting tuned, I've added a carbon intake tube (replaced plastic accordian) and a ported TB. It's nice using the KL in conjunction with my AFR and EGT guages as it let me know that I did not need to retune for the mods. The ported TB leaned me out about .1 on the AFR in some instances, which means I am around 10.5-11.2 @ WOT (depending on gear/load/etc) instead of the 10.5-11.1 I used to get. Not really much, but good to know. Had I been tuned at the ragged edge, and not had the guages, it may have been enough to cause damage. Definitely a good mod...plus I use the shift light as a secondary. Stock one is around 6k, KL is @ 7k.

Knowing what I know, if I were a WRX owner, I'd pay the 100 bucks just for the shift light feature.

Main problem is that they are generic. So when it says 'white wire goes to X' you have to figure out where X is on your ECU.

Looking at picking on of these up and it seems that the shielded wire is the way to go? anyone have anymore info/write up for an 04 wrx?

I'm not sure that you do want to go with a shielded wire. I think someone in this thread used a shielded wire and had some probs with it.
