I think people have a lot of the same confusion about the knock lite as they did about the DTEC when it came out.

Reality is TurboXS can't focus on JUST Subarus and Evos - they need more generic products (and not just boost controllers) to grow the business. The DTEC line and Knock Lite are part of that. Don't keep thinking "But I already have a UTEC" - yes, you do get _some_ of the functionality for free with the UTEC. But think of folks with 2.5RSs who can now go to TurboXS and get a full tuning suite - DTEC + Knock Lite + Tuner, from one company, that integrates beautifully and looks very trick hooked to a Gameboy. You can tune fuel, log and monitor EGTs + Wideband AFR, and have a nice knock and shift-lite to boot, all for under $800. Ditto for just about any other car. Even though they're still expanding what cars they make full-featured UTECs for, the DTEC gives them an in to alllll the other cars that there would never be enough volume to justify the custom development of a UTEC.

The better question is: "Why would I bother?" What prompts anyone to believe the TurboXS knock detection algorithm for a Subaru engine is any better than the one used by the stock ECU?

Because people have popped motors while running the stock ECU?

Because the WRX ECU stops listening for knock at high RPM?

I'm not saying the TurboXS knock detection algorithm is "better" for these reasons, but I *am* saying that the stock ECU's detection algorithm is not perfect.

No way, Subaru engineers spent eleventy billion dollars in testing on everything and it is all perfect.

My question is not weather or not to get it, or even weather or not to get a seperate mic (yes, i'm gonna get a seperate Bosch one), but weather to go TXS or Link (leaning toward the TXS).

Is there anywhere else to tap into the neccessary wires away from the ECU?

Why would I bother

Some situations you fail to consider

(1)Because early 04 STI's that Subaru "engineers" so wonderfully programmed had to be reflashed to stop the pinging. Engineers are never wrong

Since I own one of those early 04 STI's and had a knock link installed at 500 miles I could add toluene till the knocking stopped at the electronic level till the UTEC came out. Knock lite works the same.

(2) Since "non engineers" are now able to reflash the stock ECU and send it to all climates of the USA etc. Could it be possible that they screw up the programming as good as the factory engineers on the early 04's only now the knock is at the electronic level and as such the owner doesn't know his cars knocking. Blissful in the knowledge he got a wonderful reflashed EMS

(3) I have heard many stories of tuners who also set the knock count on the UTEC to over 30 so that the owner thinks he has a well tuned car but its knocking and the CEL light doesn't flash. With the Knocklite's user install friendly setup it gives the owner of a badly tuned UTEC an easy double check system and hense weed out the bad tuner who blames the UTEC for the customers blown motor.

(3) Since I'm one of only a few who have Knock Link, TurboXS protuner with knock sensor, UTEC and Knocklite in my car I can say that it works very nicely. I also have Delta Dash.

(4) I'm also one of the very few who have actually toured TurboXS engineering in Australia and have met first hand with the University trained electrical engineers they employ. It ain't no Ma and Pa outfit with over 25 employees there alone not like some EM companies here.
They have managed to attract people from other Australian EM companies which I not allowed to reveal. I'm guessing Motec and Autronic are on your sub par engineering list also.

All you need to do is get a stock knock sensor, bolt it to the block and plug the knock light into it, not sure if it is compatible with other knock sensors... On TurboXS's site you can pick up the Knock Light along with a Bosch knock sensor.

BTW, anyone have the pinouts used to tap into the knock sensor? Anyone have ideas on stealth mounting of the knock light which still lets you get to that button used to program it?

So is there a benefit to this if you have a Tuner PRO that already has the Bosch knock sensor??? Or is this just extra security if you already have the PRO?

The knock indicator lights on the TunerPro are hard to read. This will be much more capable of getting your attention if there is a problem. You can use the same knock sensor that came with your TunerPro, but the TunerPro does not really have an equivalent function to the knock light. Also the TunerPro does not have the shift light at all.

Note the diagram. The competitor is a knock-link.

Thanks Nathan and Jarrad... explains it well. Looks like I'll snatch a cheap non-pro Tuner and then the KnockLite.

right on. And does the fact that it is non-volatile memory mean I won't have to reprogram it after unplugging my battery?

Because it's not a single level you can twiddle with a knob. The feature as presented here "listens" to your engine while you set it and hold it at 3 different RPMs and produces a noise floor "curve" across the RPM band. Much nicer than a single adjustment. BTW I'm not a Knock Lite user yet, I'm just regurgitating what Serendipity said earlier in the thread

Default ..thanks..

was never really sure if this was something i should have, other than it would just have been more conspicuous than the check engine light while blinking and therefore i would better notice it while grasping the wheel for dear life as my Rexy shot down the road like a rocket

but appears from the write-up that it is certainly more than that.... a system of 'checks and balances' if you will for the UTEC tuned by a vendor (like mine).

that said. I'm SOLD.


does it come with a 'clear cut' installation of which wires to splice into on the utec/ecu?

Default another question

Is there a diagram or instructions showing which wires are which coming out of the ECU (specifically the knock/coil pack wire cuz I don't know which one that is).

EDIT: Also let me ask this (if it hasn't been already covered)... what is better for monitoring knock. The knocklite wired into the factory knock sensor or a separate Bosch knock sensor bolted onto the block (same place as factory but on pass. side of the block)???? I thought the factory knock sensor stops listening after a certain RPM?

Default ...

thats where i gotta think 'no'. only because isn't this a universal product? in other words they're selling this not as a wrx or sti specific product, but useable in most vehicles.... so certainly they can't include pics or all car's ECU's....................

PDX can you help us figure out which wires to tap on the wrx and sti ecu's? would it be same across the board of model yrs and wrx vs. sti, or different wires for each.

course i do remember having an old 2002 ecu pinout diagram....... not sure what i did with it though.... assume its likely floating around nasioc somewheres. little search prolly do the trick......................

^^ True... I'm sure there's a pinout somewhere, just takes a bit of searching. I was just being lazy but it shouldn't be hard at all.

It's not that the knock sensor itself stops listening, it's that the ECU starts ignoring it after a certain RPM because of the noise level.
