    No 05 and 07 are different.

    Tops, dash, crank trigger, ect.... are differant

    IMO go with a vtec reflash with logging
    you can change the rpm limit to your liking and the fuel map is also user changeable
    there are a few maps available for a 05 ecu for different injectors

    If you plan on doing a lot of modding dont waste money on any other ecu stuff. Get motec and be done.
    Its spendy but will save you money in the long run.

    Its the best of the best.

    mainly was just looking at the difference between 05 and 07 ecus and why a 07 cant fit on an 05 motor now after i read i see why im going for a fast reliable ski like to get to the 75 to 80 mph range hopefully i have read bout the vtech and like the motech from what i saw and read bout it but dont have that much cash now my motor now has cp pistons molnar rods light weight cam and valve train x charger and 42 lb injectors havent touched the ecu yet just got done building the motor just looking to see what my options for ecus was thanks for the help
