How to connect my megasquirt to Quad Spark and IGN-4 coil

Post by Smithius »

Hi guys

Im a bit of a newb to all of this megasquirt stuff and i want to know how difficult it is to connect my megasquirt to one of the new quad spark ignition modules.

I have a MegaSquirt-II EMS System - SMD PCB3.57 which i bought about 2 months ago which i havent installed into the car yet but as i wan ignition control i think this may be my best option.

The car is currently running a electronic distributor with internal ignitors, it is also locked because i was previously using it in a carby/boosted setup where i didnt want any ignition advance. Now i do want control so is this my best option?

Is there much internal wiring that needs to be done to the pcb

Cheers
Matthew

Ok. So can I still use my distributor for for the crank trigger?

You can do - but it's not ideal. Cam chains stretch and gears chatter. Simplest way is a crank sensor and wasted spark.

This is true. Just going to be hard to fit a trigger wheel in with all the supercharger gear.

They seem to work ok sandwiched between two pulleys - provided the sensor can be correctly positioned.
