    Hi
    I am not sure which sensor type you are refering to.
    If you mean Lambda sensor ????? the most reliable one is the NTK, all the lambda sesnors that we use thou will give you good information providing the water has not killed them.
    Maybe you could get someone to help you write your post with some more explanation of what you would like to know.

    Cheers

    For CC race first just change MOTEC-SEADOO adapter loom or best make complete new between motec and engine. I was issue with seadoo/Motec adapter ( stock ecu A-B connector - Motec )
    this is most important.

    I think Lamda enought for AFR, and I have more oil temp sensor, but no EGTs sensors.

    Ohh ok, I get the idea

    No.1 most important is AFR sensor (Lambda), prefer NTK

    If turbo then exhaust temp is useful to keep an eye on things.

    Is it supercharged or turbo?
    What boost level?
    What octane fuel will be used?
    Is the compression ratio standard?
    How will you determine how much ignition timing to run at full boost? (very important)

    Cheers

    it`s turbo.
    i plane to boost it around 2 bar for high boost 1.5 for low boost
    i used 1600 cc injector + Q16 (116 octane)+ methanol injuction
    standard compression ratio
    How will you determine how much ignition timing to run at full boost?

    i need help for that

    Hi Majed Al Sharshani,

    You must have intake aluminum for Hi boost also otherwise it will be broken at over 16-17 psi.
