Basic CAN Mapping Kit for MBE CAN based ECUs (MBE985)
Mapping kit for MBE CAN ECUs, translates the information from your high speed USB port to the CAN data required by the ECU. This hardware can be used as a simple diagnostic tool to analyse the ECU, update software, transfer whole ECU chip files, modify & edit maps. Live Map can be used on MBE9A4 ECUs onwards.
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 MBE-MAP-KIT-3-CAN-ADP3.
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.
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.
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.
