Rewiring for new ecu & security
I'm preparing an MX5 bases Haynes Roadster for track use. It all seems to work ok (not been on track yet but private road test seems ok) but
firstly, there is a ton of unused loom and connectors taped up etc that I really don't like. Secondly, I plan later to turbo or SC it, and ME221
ecu looks like the weapon of choice.
I think i note though that the ME221 plugs into the standard loom connectors, much of which i want to remove.
Is the key & security module required to make the standard ecu work, or can it be removed.
Has anyone here done this ? I wondered if the approach was to get the loom out, lay it on the floor and remove all the wrapping and see if is then
possible to retain the bits I need. Or do i just buy the parts and start again, i don't think minimal wiring to run the engine OK can be that
complicated ?
any tips/thoughts welcome.

You can buy the ME221 as a mx5 "special" or with a generic loom that you would need to terminate for all your sensor connections.
I expect the security stuff is required for the existing ECU though. And yes, you can open the whole loom up and start taking the cutters to it, but
care and a decent wiring diagram is needed. You don't want to chop is all about then find the car won't run, I would be tempted to do it
in the car, double checking after each cut.
