Welcome

Here is a collection of information, software, products and services surrounding Rover MEMS ECUs.
This applies to cars (engines) from around 1991-2000+ including Rover (Mini, Metro, 100, 200, 400, 600, 800), MG (F, TF), Lotus Elise, Kit cars - Caterham, Morgan, Westfield etc

Diagnostics
I have spent time working on these ECUs and can now provide diagnostics software for all of the engine ECUs listed as well as the RC5 airbag module
See the Diagnostics section of the website

Remapping
I am also working to provide the ability to remap the ECUs, more information is in the Remapping section of the website

Mini MPI Injection Timing (Siamese port sharing/charge robbing)
Here is some info about the Mini MPI Injection Timing - an important issue caused by the siamese intake ports
Mini MPI Injection Timing

5as Immobiliser
I can pair 5AS Immobiliser with key fobs, however, due to (car) security I will not be offering this as a tool.
If you want a 5AS unit pairing with some key fobs then please Email me
I could do this as a postal service or in person if you are local to Manchester (UK)

ECUs/Modules

There is a mixture of ECU versions across various cars including Rover Mini, Metro, 100, 200, 400, 600, 800, Land Rover, Lotus, MG, MGF

MEMS 1.2 ECU
MEMS 1.2 ECU

VERY early SPI cars (1991) without Catalytic Converters- 1x36 pin connector, smooth lid, X on the base/bottom, vacuum connector on the corner

MEMS 1.3 ECU
MEMS 1.3 ECU

Tend to be used on early SPI cars (1992-1993) - 3 pin round diagnostic connector - 1x36pin and 1x18pin connector - lines and screws in the lid - vacuum connector between plugs

MEMS 1.6 ECU
MEMS 1.6 ECU

Used mostly for SPI cars and some early MPI cars (1993-1999) - 3 pin round diagnostic connector - 1x36 pin connector, sometimes also 1x18 pin connector - lines in the lid, but no screws in the lid - vacuum connector next to first plug

MEMS 1.9 ECU
MEMS 1.9 ECU

Used in MPI cars - 16 pin "OBDII/OBD2" style diagnostic connector - cross on top, vacuum line next to the main connector

MEMS 2J ECU
MEMS 2J ECU

Uused in Mini MPIs and cars with VVC - 16 pin "OBDII/OBD2" style diagnostic connector - 2x36pin connectors, left black, right red - large X in the lid - no vacuum connector

MEMS 3 ECU
MEMS 3 ECU

Used in newer MPI cars with/without VVC - 16 pin "OBD" style diagnostic connector - no vacuum connector

RC5 Airbag module
RC5 Airbag module

Used in MPI and JDM Minis as well as other Rovers

5AS Immobiliser
5AS Immobiliser

Used in many Rovers including SPI and MPI Mini
