Megajolt Programmable Ignition Controller
Megajolt Programmable Ignition Controller
This is a how too to put megajolt on your mini,
I did this a few years ago and have been very pleased with how it works.
Basically you remove distributor , add a coil pack, crank angle sensor, ford EDIS module and megajolt computer too control it and you have fully programmables ignition with rev limit and user outputs.
Need:
Ford coil pack or similar (hyundai one works for memory?)
Ford crank angle sensor (or any that work with 36-1 tooth wheels)
Ford edis 4 ignition module
Megajolt computer
Ford parts can be sourced from a wrecker , but i purchased mine from overseas along with the 36-1 wheel.
From here : http://trigger-wheels.com/store/
Megajolt computer i bought pre-built from their website
: http://www.autosportlabs.com/
Most of the installation info is on there website but ill put here to make easy
wiring diagram (this is for version 3) the plug is slightly different for 4 as there is two more option plugs double check on the website
pretty easy but take you time to make it neat and (i hate messy wiring !!). I measured the lenghts i needed to put it where i wanted in the car and then made a loom just for the megajolt . Computer is under dash with the edis module and coil pack is in std spot. For power i pulled the ignition wire back from the distributor . Be sure to fuse your power !
The crank angle sensor has to be set up like this :
so as long as the sensor is positioned at 90* befor Top Dead Centre at TDC then it can basically be positioned anywhere ( hope that makes sence). I place my sensor on the engine mount braket and even though the sensor is at a weird angle it still is 90* befor TDC.
after its all set up plug in you laptop and see if it all works
upload a basic map to get you started then just fine tune to suit your engine , if you have no idea best to get it tuned by someone who does , although the basic map will be safe
