CAN type MBE ECU Mapping Kits
MBE software & mapping equipment is only for use with MBE ECUs
Why use separate USB to CAN interfaces
We produce a separate USB to CAN interface (985 & 973); there are many reasons for doing this. The most important is that USB is quite fragile & susceptible to external interference particularly when used in the electronically noisy environment of vehicles. It is very easy to damage, if not destroy the USB & Motherboard of your computer. MBE use stand-alone units that convert USB into CAN, thereby giving as much protection as possible.
CAN was specifically created for the motor industry to be rugged & stable within this electronically harsh environment. If we were mount the CAN within our ECUs, this puts the USB closer to potential interference, which could disrupt communication between your Easimap software & your MBE ECU.

USB Cables
It is recommended that you do not use a USB lead longer than 1 metre to help minimise external noise into the USB cable.

We advise you not to manufacture any of your own USB leads; if you were to wire it incorrectly you will definitely destroy your USB & probably your motherboard.


Mapping kit for MBE CAN ECUs


Professional mapping kit for MBE CAN ECUs using infinitely adjustable rotary encoders.

MBE-MAP-KIT-4-CAN Professional mapping kit


Please note that all Cosworth & Caterham MBE ECUs are locked during manufacture, which means they cannot be modified in any way. You can only use the CAN mapping kit & Easimap 6 software for Real Time Viewing as an aid to diagnosing faults with sensors & replacement or setting up of throttle pots.

The CAN mapping kits come with OBD2 connectors & depending on your car & wiring harness you are likely to need an adaptor to allow it to interface, please see below.

CAN Connector

If you have this part fitted to your harness (red, yellow & black type), when using any of our mapping kits you would need to buy this adapter MBE-MAP-KIT-3-CAN-ADP3.



This adaptor is used to link the MBE985 & MBE973 to SBD Wiring harnesses, you will need one of these to use the above mapping kits.

OBD2 Connector The connector shown left is an OBD2 connector, this is a standard connector used by all production cars since about 2006. It normally used within the drivers compartment for diagnostics. It is also used by some companies using the MBE systems such as Cosworth, Caterham & a few others.
It is not ideal for motorsport use or use within the engine bay, so on our own harnesses we use a different connector (see MBE-MAP-KIT-3-CAN-ADP3 above).
If your harness is not equipped with either of the connectors shown, we do manufacture a few other adaptors to suit some specialist harnesses, please email us a photo of your connector & a description of who originally manufactured your harness as this may help us to pin point what you have. If your harness has a connector of an unknown type, we would recommend you use this adaptor shown right LM9A4-OBD-COMMS. LM9A4-OBD-COMMS

SBD Programs & Mapping
All our ECUs come ready programmed with either a suitable map from one of our range of kits or a good start-up map.

Map included free of charge with a new ECU supplied by SBD, the map will be built as close as possible to suit your engine based on the information supplied by you, which can then be optimised on the dyno or rolling road

Same as above but for SBD customers upgrading to new engine specifications.

Programs for non-SBD engine specifications.

Custom program for MBE9A9 ECUs

Due to the age of some ECUs, Eprom type are no longer reprogrammable.

SBD mapping of engines can be done at a rolling road or dynamometer of your choice. Alternatively the car could be mapped either at a race track or, if the car is road legal, mapped on the road. Due to the large number of engines we have programmed, we have a massive amount to data relating to our main range of engines. This allows us to program on the road with our closed loop lambda control.

Engine Mapping Options:

1. If budget is no objective, we would always suggest that to get absolute peak performance, engines should be programmed under controlled conditions, initially on a dynomometer, then fine-tuned on an accurate rolling road, finishing off with in-car mapping on the road or at a race track for the ultimate refinement.

2. Depending on your budget our next recommendation is to program the engine on a rolling road first, then finish with some road mapping.

3. Alternatively if you are in a hurry to get things finished, due to the fact we have an extensive map history (please check that we hold a base map suitable for your engine type) for all the engine specs we have developed, we can build a good base map that can be used to map your engine on the road, if your car is road legal.

However please contact us for more details regarding which is your best option.

SBD mapping of engine per day. This is only the cost of an engine programmer on a daily rate, it does not include travelling cost or expenses.

SBD mapping of engine per hour (this is as above but for an hourly rate if you think the mapping or reprogramming can be carried out in a shorter time) This is not usually the case though, problems & delay nearly always happen & almost certainly beyond anyone’s control.

SBD Remote mapping of engine per hour using TeamViewer. This YouTube Video shows Steve remotely mapping Tom Gaval's Caterham CSR, 2.3L Duratec in Pennsylviana, USA.

SBD remote log-in using TeamViewer for 10 mins only, usually suggested for either training or fault finding. If you require a longer period of time, please see MAPPING2-VIEW. If you are unsure as to how long you require, please contact us for advice.

SBD mapping of engine per day outside the UK, it does not include travelling cost or expenses and travelling to & from the airport.

When purchasing second hand ECUs, please note the following;

If the ECU is still a current issue i.e. advertised on our web site, it can be reprogrammed, costs from £95 per unit.

If the ECU is an older model, it is recommended that the ECU be only used for the type of engine it is already programmed for. If you require an older model reprogrammed, costs are from £140 per unit dependant on the age of the ECU. It can cost more for the unit to be reprogrammed than the purchase of new ECU. In addition, if the unit breaks, the older units (e.g. 912-900) are irreparable.

Testing/Repair of ECUs

If your ECU requires testing and/or repairing, the ECU must be sent to us with full details of the fault.

Testing only costs from £90 + VAT | Testing & Repairs costs from £150 + VAT
