Knock Reading

[FD3UK]

I am running a Microtech on my FD which does not show knock readings like the PFC can. I have been surfing  :Typing  to see what is about for monitoring knock but have not much luck. Wanted to see if anybody had some pointers or experience in some equipment they have used/tried.

Here\'s what HKS say bout it-

The HKS A/F Knock Amp is an electronic monitoring device that displays two of the most vital engine conditions for tuning; engine knock and air/fuel ratio. Engine knock occurs when there is abnormal combustion knock as detonation; which can rob power, reduce engine longevity and even lead to catastrophic failure. The A/F Knock Amp utilizes the factory knock sensor, allowing you to monitor in real time engine knock visually and audibly via earphones (not included). By adding the optional HKS wide-band O2 sensor, air/fuel ratio can be monitored visually  on the back-lit LCD display. A warning function can be set for both engine knock and air/fuel ratio where an audible alert sounds if the preset warning is reached.

HKS Europe site has it listed as £495- sure this could be sourced alot cheaper though...

bob rawle developments do a knocklink as a stand alone device using a bosch sensor that will light up under knock conditions lots of scooby owners use them

Search for j&s knock sensor on rx7club.com/forum  may be of use to you.

I used to run a knocklink on my Scooby. It works well, but it\'s an ugly MoFo........

Hi Iwan,

It is possible to use a KnockLink on rotary engines, however the output must
be carefully interpreted.  The engine noise will naturally increase with
engine speed, however the KnockLink does not have any engine speed
correction.  Therefore the LED display will increase with engine speed even
if no knock is present.  To detect knock you must look for a sudden change
rather than a progressive one.

I prefer to use a KnockBlock which allows you to monitor the engine noise
via headphones, but you need to know exactly what you are listening for.

Regards,

Walter
