    That being said..I am hopeful to be wrong!!! I got the $500 at hand...
    i would like to get my hands on a spare ecu myself and see what i could find out about flashing it....

    You are correct I think the drive by wire is one of the more difficult things to overcome with any car when producing a fully tunable ecu

    it's not just how to tune it. it's deciphering everything. now you have pages to map the commanded power for the throttle position, the commanded boost to attain that power for the rpm, the throttle body throttle angle for the power and actual boost ve the commanded boost, the bypass valve condition.. the logic may not be as hard to understand as just finding which tables are for which function. it's something i've thought about but not actually done. but maybe now that i own my first obd2 car i'll see what i can find out (my newest cars before this was a 1993 skyline when i lived in japan)

    I was just refering to the drive by wire system being a PITA to overcome...other than that I really dont know squat about developing a fully tunable ecu. I had a Hondata KPRO on my 02 Civic and the parameters that you could adjust was amazing. It was so nice to just have all the tunes done for you based on what octane you wanted to run or performance you wanted (once taken to the shop and 4hrs of dyno time later), just sit your laptop on your pass seat connect to the ECU and choose which tune you want, datalog, check codes, ect ect.

    it'll get there. i mean it'll take a while longer than an old honda but it'll get there. our car can have an order of magnitude more pages to go through but most don't need to be modified. it's just figuring out which ones do.

    IIRC, there were issues with tuning the Nissan gtr when it first came out. Nissan swore it was un-tuneable but look at them now
