John,
Just a very quick question re the later ECU code.

Does it have quite a few parts of it that are dependant upon particular flags being switched in particular config memory locations or indeed code locations?

I've got quite a few bits in mine where there are sections of code that are bypassed depending upon certain bits in memory locations that are initialised to certain values on ECU start or certain code location values that are obviously set in the original coding of the ECU and I just wondered if it was the same in the later cars.

Cheers

Yes very similar.

Can you think of any reason as to why or is it down to the fact that the code is probably quite generic and used across a range of vehicles and so it's easier to just tick certain flags depending upon which engine etc?

Well they all have six cylinder code in them, presumably Mitsi just use a code base for all their ECUs for various cars and modify it?

Lots of routines that are called, make a comparison with a ROM constant and then return doing effectively nothing.
