[Roadsters] Megasquirt and/or Megajolt users?

Just went and looked at the website and thought I should note a couple of 
changes.
1) I have removed the oil feed line from the coil mount as it is not 
nescessary.
2) I also removed the leg bolted at the oil pump mount which seemed 
overkill. (but I wanted to make sure it was solid at the time...)
3) There is a comment in the writeup about "plugging in  numbers" - The 
Megajolt Jr. was pretty basic when I used it, and pretty much all you had to 
do was set up your RPM and Manifold pressure axis, then fill in your 
ignition advance in the grid.
I believe it may be a little more involved now, and the Megasquirt is more 
involved, depending on what you want to incorporate (temperature related 
advance, fan control, rev limits, etc.........) and requires some board 
mods - wiring in jumpers/changing components. But, using the Megasquirt 
doesn't cost much more, and gives you the option to go full efi later if you 
like. (A freind has done just that, running just the EDIS system for a 
couple of years now.)

There is also the option to control the coils directly with the Megasquirt 
and also requires some wiring/component mods.

Just had my car down at Ross's place today in preparation for the BC Spring 
Thaw Run on Friday......Persistant oil leak!
