Does anyone have a wiring diagram and instructions for the Carter EKE that Clark's used to sell? I would appreciate a copy.

Thanks!

Quick instructions.

Mount the box in any position but its preferred that the wires point down to avoid water running into the unit.

Ground black and brown wires separately.

Blue knock sensor wire. Do not route near spark plug wires.

Tuning –
Disconnect blue wire then set timing.
Turn the CYL pot to the appropriate cylinder number.

Start with the SENS adjustment at minimum and test drive. If knock is heard readjust 1/16 turn in the direction of arrow. Repeat until only several light, initial knocks are heard. Do not adjust to the point where you do not hear any knocks. If knock persists at maximum setting check the sensor mounting or relocate the sensor.

Testing –
With the engine running tap lightly with a small metal tool near the sensor. Timing should retard and return to normal after tapping is stopped.

If timing does not retard disconnect the knock sensor wire and touch it to 12 v. If retard occurs then the sensor is bad. If no retard occurs then EKE is bad.

I received a new one of these in a box of parts. Before I consider installing it, wanted to ask if the general consensus on - does it work?

140 or turbo.

They work... but very crudely.... 10 deg. retard on ALL cylinders..for X amount of time after sensing ping..

I use one on my custom Turbo engine with two pickups and a filtering media between the sensor and head...but I'm starting with 36 deg. BTDC at 2000 rpm..

So it still falls below the 29-30 Deg. we need to make maximum boost. but performs well enough.

Thanks Matt. I remember when they first came out wondering if the electronic box would stand up to the under hood (or deck) temps.

Would you have a wiring diagram for your setup? Also, how do you set timing for 36 BTDC when the tab only goes to 24?

Top of this topic is the diagram..


My distributor is a Custom recurved unit...

Static/ Base is 14 btdc...... full mechanical advance [ 11 ] in by 2000rpm.


Underhood temps after shutdown have not been a problem.

Wiring: the second sensor just taps into the blue wire?

Filtering media? Would that be a fiber washer? If so, the sensor must have a dedicated ground wire? I assume the sensitivity adjustment on the unit could not cover that for you?

Wonder how to procure a second sensor these days. Specific to the Carter unit or generic?

Just parallel the two to the one Blue wire.

I used to have multiple units... New in box when the swap meets were full of them... $5! After reporting this years ago I sold the rest quickly for considerably more and yet considerably less!! gg

My sensors use a bracket to push the end against the head.... Sensors do NOT screw into head...

Filtering media?? piece of brown grocery bag worked for me..

I had one of these on my van that I pulled a trailer with. It did work but you would just loose power and it was noticeable! As someone said it retarded the timing on ALL the cylinders. My experience in using it is when it actually worked it worked to well and for to long. I could not get an adjustment where it would only retard for a second, it would actually slow me down by almost 5 mph before it would go back to normal. I found that I could actually listen and drive better than what that knock sensor could do.
