Find your ECU information here, all you need is a HW number:

Nice.
So 1 HW number => 1 SW number
Is the viceversa always true? Don't think so.

So 1 HW number => 1 SW number - NO

1 HW number => a lot off SW numbers

This definitely makes sense due to the politics of some makers of releasing ECU updated. But then why if I search for a HW number, say 0281010877, only one SW number turns out? (1 037 353 776 in this case) Is this the first SW number the HW was released with?

What about this one? http://autotekelectronics.com/autotek/i ... 0281010877, http://www.ecutechnologies.co.uk/ecus/8 ... 0281010877, http://car-ecu-repair.com/peugeot/engin ... 02738.html, .. all first page gugl hits for 0281010877.

New set of combos to add to the list:
0281010877 9647473780
0281010877 9645592880
0281010877 9645532880

I'm more than convinced that there are many, many more than those I've gathered here peugeot-406-hdi-2-2-all-known-ecu-sw-and-hw-versions-t199 :( .

Although those last three SW versions are quite high :?: I might have jumped the gun :oops:

(clap) (clap) Nice addition to the web pack m8! :) No more xls!!

I've been gathering the ECU lists, too. Time to compare and hopefully ditch them :D. It's so painful to manage all those formats and whatnot..
