    Your firmware version is noted on backside of ECU.
    I think you have an "old" version, not knowing which, cause my old handheld said prg 07, ecu 05 which is firmware 2.37, prg/tune 05.

    I too have a ez1.0 with the new color screen. I have kept all my values but the screen locks up about every other time I start the car. A quick reset and I'm goodbut that's a pain. I will be at sema in a few weeks and I'm going to ask a fast tech if the 005 is a fix for the color screen problems people are having.
