Yes, sorry.  You are correct MBE.

Re #10:

Does your car come with a diagnostic plug like this:

You'll need one for the MBE985 connector cable.

Ok update:

I have the required lead from SBD (They are about 2 minutes up the road from me) and have Easimap installed on my bootcamp'd Macbook Pro.

When I hook the lead up and start the car, Easimap seems to find the interface but doesn't recognise the ECU (the dialog box at the top is Yellow/Black flashing).

I have an MBE Part No 72212, Software 967bc474 (as written on the ECU box).

For anyone with experience with Easimap, is there something that I am missing?

I had assumed I would establish the interface, then I would load a config file that would interpret the data and update the GUI to match it.

Any help appreciated.

So from something I've read it looks like 967bc474 isn't compatible with the CAN interface and I need to splice in a serial cable and use a serial to usb cable.  Does anyone have any experience doing this?

Although it is expensive, SBD have a serial lead, supposedly reading other forums for cars that also use MBE ECUs a standard serial lead will not work or not work reliably: https://www.sbdmotorsport.co.uk/MBE-MAP-LEAD-mapping-lead-for-mbe-serial-based-ecus.html, you could then use a standard serial to USB adapter to attach to the Mac.

Thank you aerobod, this looks like the right approach.  I think I will go and see SBD again.

Kimble,

Do you have a soldering iron? 

If so, the bits to make a coms lead would only cost a few quid!

pinouts here:-

https://www.sbdmotorsport.co.uk/wp/wp/pdf/MBE_Coiled_Mapping_Lead_Pin-out.pdf

You may also have to add three pins to the ECU connector and a short lead with another female 9 way D type connector if it is not already present. 

See ECU pinouts here:-

https://www.sbdmotorsport.co.uk/wp/wp/pdf/MBE967_Pin_Out_Information.pdf

You need pins 6, 14, & 32 (ground, receive, & transmit)

I've had limited success with cheap USB to RS232 converters, but found this StarTech one to work well:-

You'll need Easimap release 5:-

Note:- Easimap 5 is a 32bit program and does not work in 64bit Windows.

Thank you, I should have all I need in a couple of days.  I'll see what easimap says.
