[s-cars] Upgrade existing ECU to MTM stage 3

[TM]

Funny how this cycle works-

I got my car, thinking I'd just chip it and be happy and now
I'm looking long-term at a direct ignition retrofit, RS2 goodies,
track wheels and tires, more wheels, possible V8 front clip down
the road, etc.

Anyone know if a CRB or other O1E based 6-speed can bolt up to
a 200 which uses a 016 gearbox? Maybe a S8 gearbox? :-)
