megasquirt/jolt

Maybe you're squeezing all you can out of a 998, or going large-bore with a 1380 (or even larger!) - either way, let us know all about it here!

megasquirt/jolt

Postby max midas » Thu Sep 29, 2016 9:03 am

I'm getting all the bits assembled to install my megasquirt ignition.
Could anyone who has installed one of these advise on where they sourced the 25uF at goes between the coil pack and earth?
Or even if they've put one in at all as some builders online deem it unnecessary.

I've got a mega jolt on my mk3 daily driver and used to have mega jolt on my mk2 daily driver, I have never fitted a capacitor on either car.

negate any rf interferance? I don't know, but the diagram I've been working from has one.
Do I have the right diagram?

I thought that grounding the shield on the cable was to isolate from interference.

The sheild on the pip/saw cable and vr sensor isolate from false signals going to and from the main board, so I presume the capacitor is to stop rf noise on other stuff like radios.
