My three previous Minis were fairly simple: one or two carbs, fairly simple wiring, manuals galore. 38 years after my last Mini 1000, I now have a '96 Rover Mini Cooper, Spi and a very steep learning curve ahead of me. The most ominous is the ECU. I see threads here about resetting it, having it go to memory to reset itself, not working at all or badly. How or where can I pickup some rudimentary information about these.? I worry that the local MINI dealer will not know how to deal with any problems I may have with it. So far, all is running very well, just anticipating. It's still a Mini after all.
Education. Where Do I Start?

look in the forums for
Injection Mini Specific - SPi/MPithis will give you the info, most problems with the spi is due to the elbows on the vacuum lines cracking

Once you get your head round fuel and ignition maps and the various sensors needed to feed information to the ecu, you'll wonder why anyone would want to use anything so complex as a carburettor!

I seriously doubt your local MINI dealer will even touch one of these. Find a Mini specialist OR start reading. There a wonderful pinned topic on this forum that gives you a great bit of info on the basics...and what typically goes wrong. The ECU on these is very good, but basic in the means of what you can do with/to it. Get yourself a Rover Mini specific scanner or download (search this forum for info) one and run it on a PC.
These can give you some headaches when they are are acting up but when they aren't, they are wonderful. Nearly all of my problems on my 94 were mechanical based. Its has NEVER left me stranded due to anything ECU-wise.

Where, on an SPI, does the scanner plug in?

MPi is under the dash, left of the steering wheel.

Be aware that standardised diagnostic equipment (OBD) does not work on a mini. You will need something like an ACR4 (or ACR2) code reader with Rover pod 3 or later and a specific harness.
