Hi All,
I am getting a SPI motor to put in my '88 city but can not find a reference to the engine number.
Hoping that some one on here can shed some light on it.
The engine number is 12a2ej34 338779
And the ECU is a MNE101170
It is from a jap spec car but I am unsure about anything else.
Cheers Pete

Not even on my list, and that's taken from the Rover Parts book...

But being a 12A2E motor, it's of SPi cooper origin with 10:1 compression ratio and probably a 3.2 final drive if it's a manual.

The ecu confirms this as that is a Manual Spi Cooper P/N

Thanks for that, good to know that it should be a Cooper motor.
Cheers Pete

Re the ECU info...... following extract from Sprockets wealth of information

Just so you are aware, there are two styles of ECU part numbers. ALL SPi ECUs start MNE, early ECUs then used a five digit number, we are not interested in these, the later ECUs use a six digit number and are more logical arangement. of all the ECUs I have come across, the late ECUs numerical code starts 101, the next digit, is 0 for uncoded, and 1 for coded, the next two digits determines the Engine. in the case of the mini 70 is the Cooper and 50 is the non cooper

I supose one way to determine if your car should have a coded ECU is if you have a factory fit alarm and fob. Behind the dash on the bulkead, the Alarm/ Imobiliser is fixed. Its a black box about 4x6 inches. If there is an alarm/imobiliser, there will be a white sticker on it with a large Letter circled in black, this letter denotes the type of alarm and the region. I do not know any more than that regarding these, other than i believe the alarm to send a digital signal to the ECU and the ECU a signal to the alarm (logical, but i have not yet been able to satisfactoraly confirm this) . This prevents any one device being replaced to try and drive the car away. Having said that, I have not had the experience to play with these, i myself am looking for an alarm box and fob at least to give my car at least a little security. When I find one, I can play. The uncoded ECU should work irespective of the alarm.


Theirfore It appears that the ECU you have is indeed a coded unit and consequently will need the appropriate and matched immobiliser and fobs to go with it.

Also is this a 1 plug or a 2 plug ECU.... and do you have the complete wiring loom to install?

Hope this helps

Thanks for the info Rob.
Unsure if it is 1 or 2 plug as I have not got it yet and I hope that if it has an immobiliser that it is easy to do away with it.
It is also coming with complete front loom.

Cheers Pete

Its not 'easy' to do away with the alarm/ imobiliser as part of it is built into the ECU digital coding. I do believe you can get this decoaded, but how much that costs, I do not know. Probibly easier to look for an uncoded ECU MNE101070

Rob, this is a single plug ECU, the two plug ecu's have a 5 numeral part number after the MNE bit and dont have a logical make up, its just a part number

[deluxe_68]

It would not be easy for me to get hold of another ecu or an uncoded one as I live in Australia, will have to wait and see.
I have heard but can not confirm that the Jap Spec cars didn't have the alarm/ imobiliser.

Makes note in Log of Mini related information......

Sprocket / DaveRob...

That is some useful information there, maybe not an FAQ in it's true sense, but definitely worth writing down somewhere, may be a pinned item in the Injection technical ???

Have got the engine and loom home and had a good look over it.
The ECU is a 1 plug one and is a MNE101170, however it does not have an immobiliser or alarm and no key fob, therefor it is not coded.
It is a Jap spec motor so I am guessing that they did not get the immobiliser function.

I thought all MNE101170's were coded.... if their is no immobiliser in the loom It might have been unplugged and taken off.... Just my thoughts but that part number suggests that this is a coded ECU and should have an immobiliser in the loom. You will find out if you fit the loom as the car wont run if this is the case..... mind you its a lot of work to fit and find you need the immob plugging in as you would either have to source the original immob or fit an uncoded ECU and an immob.... Sprocket might have a chip in about if Jap spec cars had any alterations.

There are no wires or plugs left over or cut and joined wires to suggest that one has ever been fitted.

The first picture in this post shows the loom behind the dash and the immobiliser. Is this actually an INJECTION engine complete with throttle body?

the alarm ecu is part of the body loom, not the engine loom. MNE101170 is a coded ecu
