Maybe mondeojimbo is talking about ECU software upgrades that fords would do ?

I've read a few posts were software upgrades are mentioned.

I'm quiet curious about this as well, how do you know if you buy a second hand car if you are running the latest ECU software ?

I take it would be possible to plug in a diagnostic device and read off the software version ?

What benefits would you see with a software upgrade if any?
As regards ECU remaps, how do they exactly work, do they change the timing and add more fuel or things of that nature, Are they more fuel economical or use a lot more? Do ford do remaps or is it purely specialist and what are this average price and horsepower gains for a tdci?

You have a "map" in the ECU which holds valid parameters for various things in the engine. A Ford upgrade may tweak some of these parameters or alter an engine's behaviour at specific revs and will likely just be a corrective measure. A remap will redefine the "map" and change the engine's operating paramters, such as fuelling and boost, which will allow it to provide more performance.

Costs and outputs vary (depending on the rolling road you use and the phase of the moon ;)) but you should see at least 160bhp. Another alternative might be a tuning box - these have been well documented on here and don't alter the car's ECU :D

My local fords said they upgrade to the latest software version as a matter of course when you have any diagnostics done, unfortunately it costs 67.50 +vat (£79 ish)!! you might want to try an ecu reset as well, its supposed to make some improvements
