coil near plug

Post by arnold1 »

I'm in the middle of swapping my EDIS8 to a coil near plug set up.
The manual recommends the use of capacitors on the +12V, which I probably won't use, and a 100 pF to 0.001 µF cap on the TTL trigger input wire to ground to help eliminate back-fed noise to the Megasquirt controller, which I want to use.
Hope there is someone on the forum that can help me with this option, or should I just dump the idea with the capacitors!!
I found a capacitor: KER110 – 100 pF Keramik Kondensator Kerko RM5 63V
Can someone tell me if I can use these capacitors??

I would fit a cap at each coil on the +12v feed. Same as EDIS does. Won't do any harm.

Any make of ceramic cap of the correct value should be OK on the TTL side.

Abandon the Megamanual, use the manuals linked-to at the top of this page. The Megamanual is obsolete, has not been kept updated and may have errors that were never corrected.

I was just wondering about the KER110 – 100 pF ceramic capacitor Kerko RM5 63V I mentioned because it only supports 63V.
