Vacuum Pipes
If your SPi engine is running roughly, using way too much fuel or even barely r unning at all, before you
throw the car at someone with a degree in electronic engineering to sort out, it would be a good idea
to spend a couple of minutes checking the vacuum pipes under the bonnet.
Faulty vacuum advance pipes on carburetter-fitted Minis create enough trouble - on injection cars they
cause mayhem! Most vacuum pipe problems are caused b y the perishing or splitting of the connectors
at either end, creating air leaks into the inlet manifold and sending entirely the wrong information to
the engine management system. For the sake of a few pence-worth of connector and a moment or two
to fit it, you could magic a star tling recovery of health from your engine!
If you’ve checked the vacuum pipes and found them to be serviceable, try inspecting the hose running
between the inlet manifold and the brake servo and its connections - it’s another prime candidate for air
leaks into the induction system.

Ignition Coils
While single point injection models up to 1996 featured a traditional ignition system (i.e. distributor
and oil-filled coil), the multi point injection set up fitted from 1997 onwards required direct electronic
ignition. The new quad dry coil created twin sparks, dispensing with the need to switch ignition high
tension voltage between each cylinder and therefore making the distributor redundant.
The single point injection models that continued to be built for Japan from 1997 on also received direct
electronic ignition.

For once, we’ve broken with Somerford Mini catalogue convention here to show change points
between the electronic components by vehicle identification number (VIN), rather than by year. This
is of course because it is vitally important that you match compatible electronic components with
each other, and the only sure-fire way of determining what’s fitted to your car is by the VIN. This
number may be found on the VIN plate attached to the RH inner wing under the bonnet, plus on
later cars it may also be found on a small plate in the LH corner of the the windscreen.

Spark Plugs
Minis fitted with electronic ignition and fuel injection should always use suppressed spark plugs
(otherwise known as resistor plugs), which significantly cut down the amount of interference generated
by the ignition system. The correct operation of engine electronic control units and electronic ignition
modules could otherwise be affected.

In 1991 the Cooper 1275cc engine lost its carburetter in favour of fuel injection, primarily to
comply with emissions regulations. The injection system used was a fairly simple affair, employing
a single injector housed in a throttle body on the inlet manifold. Known within the factory
confines as Throttle Body Injection (TBi), it is always referred to as Single Point Injection (SPi) in
this catalogue, because that is the name universally used by the marketplace.
The Rover Mini Cabriolet introduced in 1993 also used the Cooper SPi engine, and from 1994 the other
Minis in the line up (Sprite, Mayfair, plus the many limited editions based on them) also went over to
single point injection, set up to a slightly lower state of tune than that used for the Cooper and
Cabriolet.
Single point injection ceased to be fitted for most countries after 1996, or (VIN) 134454, being replaced
by a twin injector system known by all as Multi Point Injection (MPi). However Japan continued with SPi
until exports to that mark et finished in 1999. As you may notice from the coils section above, the 1997
on Japan spec SPi was rather different from the 1991-96 SPi set-up - the most visual difference being
the deletion of the distributor and fitment of the quad coil more usually associated with the European
1997 on MPi models.
In a few export markets the Cooper came with the lo wer performance Sprite/Mayfair engine, using that
engine’s control unit. Which countries this concerned is particularly poorly documented, so further
research may be required before ordering. A ray of hope is that some ECUs w ere marked with the state
of tune:‘Standard Performance’ means Sprite/Mayfair, whereas ‘High Performance’ means Cooper.
