Engine Management System Advice

I've read with interest lots of posts about reading what the ECU is doing through something called easymap and I'm really interested to dive in and see how all the electrics are working on my car. However, I grew up tuning SU carburetors by filing the needle and jet profiles so don't really know where to start. I presume I need something to plug into the connector behind the big black bung in the drivers side knee trim.

Any advice on what would be good hardware/software to start with on this? I'm sure I might be about to  open pandora's box but it'll be good to learn about it all.

Many thanks in advance, I'm bracing myself....

I'd suggest downloading and playing with the Emerald software and manual - but then I have an Emerald ECU.  You'll be able to see the parameters and the software.  At the end of the day, different ECU have the same thing in common - to control fuelling and ignition. These are user friendly and taught me the basics of what the ECU and software is trying to do.

Many thank Tom I will do. I have a new 310R which I just finished building so I think I have an SBD motorsport ECU.

There's a range of after market ECU that are fitted to 7s, most typically associated with the period and engine.  Emeralds are popular aftermarket ECU for K series as they came with a directly compatible plug with the Rover ECU.  As I recall, Omex seemed popular with the Vauxhall redtop engines - what ever ECU you have is largely driven by the engine generation and whats popular amongst the aftermarket Ford/ Rover/ Vx users.

I guess it's an MBE 9A4 you've got. Easimap and a lead from SBD will let you see the basic parameters but maps and data are encrypted and it won't let you change anything as they are supplied locked. There are a few specialist that can unlock them, but I'm not totally sure what that gives you as an end user. The real danger is that you'll get interested enough to buy a fully open replacement and spend lots of money on rolling roads and getting it just as you like it!  You've been warned!

The MBE Easimap software is free, but the connection lead costs about 100 notes, so be prepared! A local owner to you might lend you one though. Where are you based?

I would recommend purchasing the lead (from SBD Motorsport) and downloading EasyMap from their website.   Assuming you have a PC, if you are a Mac users things become a little more complicated.   As the ECU is locked, you can't do any damage or make changes plugging into the ECU with EasyMap, so it's totally safe to play and discover what the ECU is doing.

You will be able to data log and see live data from the ECU, which is perfect for fault diagnostics. 

You can always sell your lead if you see no value owning it.

If your ECU us unlocked simple save the map file as 'Original DO NOT USE' and resave every map as a new file name, that way when you hit the wrong key and fook it up  (we've all done a group delete  Yikes ) you simple reload the previous file and away you go.

you also have a record for comparison too.

There is an article on my personal website which introduces the basic principles of engine management which may help with your understanding of the basics and with jargon busting.
