Disagree, its just an impulse counter, not a rocket inertial guidance system. Any cheap impulse sensing device that is fast enough to capture the knock event will suffice and my motor won't explode if one day it suddenly stops working.

That's just the problem. It WILL one day suddenly stop working.

I browsed ebay, and they have a couple of options available - most around the $20 range, but I can't find one that has above a 100 Hz count speed. According to what Josh posted previously on this thread, that won't cut it considering the KLR knock count output happens around 500Hz.

Again, "so what". In my eyes a knock counter is most useful as a temporary tuning aid, not something vital that needs to be reliable. Id rather pay 20 bucks and tune with it for a month before it breaks than pay 175 and have it last forever.

I bought the Red Lion CUB7 counter I linked earlier. I will let you guys know how it works out.

Perhaps you should chill the **** out. There are way too many people on here as of late that get way too wound up over nothing, have zero people skills or don't posses the ability to express a thought without making it into a personal attack. Personally I'm sick of it and I have better places to spend my time.

That red-faced little monger was more toward the Chinaman parts than the poster.

Having worked in the manufacturing industry, I have grown biased toward anything that comes over in a boat. It's all junk and I'd rather not support it further.


As for chilling out, I find that EVERY rennlist member could take a page out of that book. People get pretty wound up on here.


Cheers

Here is some pictures of the counter. Haven't got a chance to install it in the car yet.

Help me understand this a bit more, but as this counter goes up, what do you do with the info? Just turn down your boost? I feel like the info is only helpful if I know what to do about it.

Sixline - how do you reset that counter?

Sixline

Generally yes, just turn down the boost. It could also inform you of bad gasoline.

Edit: There are many things that can cause knocking/pinging and Chris White has a nice article on his website about it. Like Tom says in the quote below even to the tuning-impaired a knock counter has some benefit.

The grey rubber button right under the display resets it to 0. There is also a wire you can short to reset it as well.

Any progress with your install? Just wondering how it worked out for you.

Sixline

Eric,

It works great. No knocking under WOT with E85. All of the knocks I see are during normal shifting/revving at idle.

I replaced the knock sensor and it counts more garbage knocks but still nothing under WOT. I will probably wire in a pressure switch so it only counts under boost.

Eric_Oz_S2

Cool. Do you get the 2 counts every time you turn on the ignition to "ON"?

Sixline

Yeah I get one or two, why?

Six - how did you wire this up, exactly? I purchased the same unit, and sourced a plug for the diagnostic port (Josh B is the man!). I spent about two hours looking at both and various threads on the curtis counters, and I am missing something.

The red lion counter has four wires:

Red is power
Black is ground
White is signal (KLR knock output)
Blue is the reset - where does this go? Should it be tied in with ground wire?
