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?

 

they are very similar but different..

the rom files are different and shouldn't/won't load from a blob..

 

Ditchys prodrive Blob rom went into my bug !

 

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 didn't run it as such , I just wanted to see if it would flash
Out of interest Simon why are some features disabled , like cat threshold ect

 

You do my head in Tone lol.

I post a reply and you state that a blob ppp map went in to your bug as if to say my post is rubbish pmsl.

 

No mate not at all , there are that many roms even for the same model , and I've no idea what will flash into what , obviously you would be mad to flash somthing like ditchys rom into my car or any that is not a very very similar spec to ditchys
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

 

Lol

The ecutek software warns if you try and load rom of different circumstances

 

You mean the good old brick scenario ?

 

No. The ecutek has recovery procedures so thats no real concern.

 

What issues could arise , would it be more of a definition issue ?

And why are some tables disabled , is that anything to do with the defs ?

 

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.

Thanks bob , very informative
Are the groups or ( family's ) quite random or logical e,g 01,02 bug
03,04 blob
Or random 01,02 bug 04 blob

 

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 thought the bug wrx (2002) runs 227bhp as standard? where did u grab the 215bhp numbers from?

 

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

crazy considering a simple decat, filter and remap will get you to about 280 lol
