Ahh, sweet clarification. Thank you VERY much.

I wouldn't say thats accurate. Its been said that the ECU for '02/'03 isn't fast enough to do computations required above 5k. Noise level is not an issue...

I just bought the UTEC TunerPro with the additional knock sensor. Where's the best place to locate it and install it? Does anyone have pictures?

Thanks,
Justin

If you know where the factory knock sensor is on the TOP of the driver's side of the block, there is a corresponding spot to put the Bosch knock sensor on the pass. side. That's where I put mine when I had the Tuner Pro.

question....

so if the ECU stops listening above 5k or so (2002).... do that mean this knock light will not indicate knocks above 5k??? how bout the utec? is it still indicating knocks above 5k rpms (or wherever the ECU exactly stops listening)?

i assume yes: just because the ecu isn't listening doesn't mean the UTEC isn't? dido for the knock light? or am i wrong and the utec and knock light are both being told by the ECU when to indicate knocks.....

Your assumption is correct. The UTEC and the KnockLight work independently from the stock ECU (as well as from eachother) and have their own knock detection capabilities. They listen throughout the entire rev band.

The range that the 04 WRX ECU listens for knock is greater than that of the 02 WRX. There is a limit, it can be changed with a reflash.

I installed mine on my 04 Cobra this afternoon. I haven't hooked it to the knock sensor and the thing is still lighting up when I rev the engine. I set the light up according to the instructions and set it to the lowest sensitivity.
Anyone else have this issue?

The shift light works fine if that helps. The cobra doesn't have a knock sensor, so I plan on using a seperate sensor wired directly to the knocklite.

Finished my install of the knocklite yesterday. Took a bit longer than expected because do to cable management and making it look nice. The housing needs to come in black in the future. Does not look stealthy at all. Will be expertimenting by using shrink tube around the housing tomorrow. Would just need to cut a small hole for the button.

Mount it in the AC vent. The above isn't a TXS knocklite but you get the idea. It wouldn't be too hard to do in the WRX.

F-it. Black paint is your friend. Or maybe take it apart and have it black anodized.

And that's exactly why I bought one. I can barely see that thing in the day time unless I'm looking directly at it....which is very rare. When it does blink when I'm looking at the road, I wonder if that is what I really saw. I don't want to have to pay attention to the little faint check engine light when I'm driving hard.
