    idle valve frequency

    Greetings,

    What will be the idle valve frequency for a 1992 Protege with a BP DOHC Engine?

    In my case I got a GTX intake manifold with the stock GTX idle valve. But before I installed the MS3 the stock ecu was controlling the IAC just fine so I guess is the same frequency.

    Looking at the Lex maps (stratifiedauto.com) the frequency is setup for 30.5Hz times 5 = 152Hz.

    With the MS3 the less that I can put is 156Hz. But in that frequency when I add more duty cycle the IAC it gets very noisy so I guess that is not right.

    Looking at the Miatas frequency it set to 170Hz and recent models as far as 400Hz.

    I will appreciate if anyone knows the right frequency.

    Regards.

    You can use 156Hz without any issues for both the GTX and NA IAC valves.

    Cheers!

      Thank you Lex.

      P.S. I am looking forward to buy one of your PNP systems for another car a 323.
