    sxr800, temp sensor bypass or R&D timing advance plate???

    What is the differance timing wise between running the R&D timing advance plate and just bypassing the temp sensor on the sxr 800? I have a new plate but if bypassing the sensor does the same thing why bother, also what about doing both, to much advance??

    Do not install both, this will advance the ignition by 14 degrees and will fry your motor

    So do they advance the same? And if I go with the plate do you just unplug the temp sensor all together?

    Its an 05. I have a new R&D plate that I bought for a boat that I sold, But if shorting the temp sensor does the same thing/timing amount?

    I think the only reason you would need the timing plate would be if your SXR was an '03 because they didnt have the same CDI unit. the plate was the only way to advance the timing the required amount for the Factory pipe.. in '04 it changed and you could use only the sensor bypass.. using them both will give too ( like 14degs as stated above) much advancement and cause detonation in your engine. just do the sensor bypass or if you want to have a more advanced timing curve get a CDI-9R or Advent ignition system where the ingintion curves are designed at the correct and safe levels for certain octane grades..

    the sensor bypass may vary from 2 degrees to maybe 5 degrees if your lucky, with the plate you get 6 degrees..........

    go with the plate.

    Question:

    Does the CDI/ECM advance the timing?

    On my ski the prior owner simply removed both sensors and the red/yellow wire is just disconnected in the electrical box, I assume this gives the 5 deg advance?

    If using say a Procom/Venom CDI, would that advance as well if the temp sensors were disabled, or is that function not enabled in these aftermarket units?

    if you have the stock ignition and the temp senser it advances more than the stock curve depening on temps

    no

    aftermarked ignitions dont do that they have good timing curves
    thats it
