Bug/Blob differences down to map?
OK - I'm displaying my ignorance here... but I'm here to learn!
Blobs and Bugs - are the engine mechanicals identical?
Obviously they're quoted as putting out different figures (power and mpg), so if the mechanicals are identical, I assume the difference is in the map?
If no... then could someone please elighten me as to what the difference is?
If yes... then since Subaru can load new maps as part of a service program (like when faced with exploding 2.5L engines for example) then would/could/did Subaru upgrade the map on bug engines to blob spec? What's not to like?

The different years have different rom files. The ppp have different rom files also.
The dealers wouldnt have installed a blob rom in a bug.
I have a list of the roms and updates and there arent many recall reloaded roms to my knowledge but there are some.
You can load roms onto different years of course but there are differences.

I was just stating on that one occasion it did flash and I'm sure there may be many occasions it won't
Sorry if I came across wrong

New age ecu's are in "groups" or family's and you can intermix roms within a family, obviously an STi rom would not work in a WRX but thats not to say it wouldn't flash. the problem with flashing a rom from a different family is that areas allocated to one function get over written by something completely different from the intent.
As long as the boost strap routine is intact its recoverable, thats in a separate area normally.
Flashing EU ecu's with JDM roms is also possible but a car normally won't run due to the hardware differences.
Bottom line is there is no real barrier to flashing in a rom, its what you might be left with thats the issue. As long as you can flash back thats not a problem of course.
JDM roms typically run as standard with far less restriction on emissions. But EU roms have to meet the stricter standards dependant on model year, (Euro "whatever") and thats why you could see later model years with different settings, for example.
The family "system" is more prevalent in 32bit ecu roms than 16 bit.

Woah, what a can of worms I've opened here, but thanks for your helpful and informative replies
If I follow the points correctly, it's not just the map (let's call that the "software") that's different, but also the Rom (let's call that the "firmware"). However, essentially it's all programmable without needing to physically change any components ("hardware").
My question is, given that Subaru have obviously decided that a blob ROM/Map is good for 226bhp and ~30mpg (and is reliable), then I don't see a technical reason why they wouldn't "update" bugs (215, ~29) with the new ROM/Map thus improving both power and economy for "free".
I can see a marketing argument that they wouldn't want to do it immediately (as they obviously want the new car on the forecourt to have a better spec than the outgong model) but we're talking cars that are 7-12 years old now...

I think 215 is the "official" figure for bugeye wrx's
