    XP800 is just a reference to how long Riva Racing has been around! Sounds like it's been quite the headache for you to tune this boat.

    Ha I thought you had a Speedster150. What kind of mph are you getting on GPS on the RXT

    I should be good then! Way more cooler and available air at idle not to mention temperature of air space and WOT should be good! Hopefully I don't have to test 70 maps.....

    I am wishing the best for you.
    I was able to pull information off my ECM which the tuner is looking for with a candooPro. Hopefully its the correct information and he can work with it.

    Good Luck.

    Update:
    They don't have the firmware for my Siemens VDO ECM but Riva is trying to get firmware from Sweeden so that I can read/write to Mapturner X without having to send ECM in for an update.

    I think they are saying they cannot tune your boat without doing test and see.. Keep us posted..
