Yup. The original KnockSense will drive an LED. $50, plus $25 for a sensor.

hello
I am planning on getting the Knocksense unit. The guy asked me to supply the engine bore he said "Each unit is individually optimized to the engine bore so please supply the approximate bore size in millimeters" i have a 2001 miata and how can i find that out. He said that he might do a discount if more than 25 people are willing to buy. Anyone interested? |
The 1.8 Miata engines have a bore diameter of 83mm.
The 1.6 is 78mm, in case anybody was wondering. |

The bore doesn't really matter, you have to tune it yourself anyway. |

Boris sets up the bandpass filter to match the calculated knock frequency of the block before he ships out the unit. Then it's up to the user to adjust the sensitivity once the device is installed. |
Good to know, thanks. Guess that's why it's a tuned circuit out of the box :)
|
ordered one (knocksense) we'll see how it works out. it was 53 shipped. good deal.

cjernigan, can i apply this to my sig please? i dont know why this makes me laugh so much, am i the only one that found it funny? :rofl: |
I have bought older J&S unit with monitor.
Havnt had time for installation yet. My plan is to measure monitor signal voltage and adapt this to EMU for ign retard. Before I will ask J&S guys which voltage range they use for the LED monitior. Falk |

'Tis gone. I sure hope someone here bought it, as that was a great deal.

A MS V2.2 is cheaper than that JS unit. Add a knocksense and you've got some serious engine managment.

man up!!! lol
i havent even installed my MS yet and im wondering about knocksense im gonna have to do that, once the motor is built that is, i see no use for it yet |
If someone knows the guy who bought the FM J&S,
I have the monitor for this unit and dont use it. Falk |
oh? Is it the nice round monitor or the ugly square one? If it's the round one I might be interested.
|
Do it Joe. We need someone to build circuits that do all kinds of crazy stuff in the community.

Yeah, but for someone using an AFPR and not wanting to go full-ECU, it would have been nice. Hell, even I haven't manned up and taken the MS plunge. Yet...
Speaking of dumb questions: where do I hook up my Knocksense Chad? Cheers, Rafa |
