Here I have an unused Megasquirt 1 V3 that I got from a recognised pro Megasquirt Builder. This one includes sparks too, set to run on EDIS (like megajolt) but it can be reconfigured to fire your coil, coil on plug or direct coil.

It works like Megajolt but is far superior as there are loads more options you can add, like water injection, Nitrous control, fan control etc including the Ignition. Theres even extra code available now to suit the 5 port mini head now too. You can also optionally log water temps, air intake temps, throttle position, vacuum, O2 (with an LC1 plugged in),
You can download loads of software for it free on the internet and update it from your PC/laptop. Comes with cable connector to build you own harness. Happy to advise on how to build using EDIS.
I already have one of these on each of my Midas (2) which I built myself. This one I bought as a spare.
These are selling on Ebay for £272 including postage from an unknown builder.
