    Nitrous Retard for coyote

    A friend of mine has a 2011 gt with nitrous, hes tired of having to swap to the nitrous program and back to the NA program with his SCT, i saw a retard box made for the LS that uses a resistor in the IAT circuit to simulate a lower temperature (like -40C) and retard the amount of timing via the IAT spark tables.

    do the IAT sensor on coyotes work like the LSX ones?
    what is the resistance needed for any temperature under 0C (coldest it gets here is 15C on the mountains)?
    has this been done before?

    I was going to do it for mine, but yes it will work, there is a IAT modifier/multipler table you will need to populate accordingly in order to do so. The IAT is built into the MAF so you will need to tie in your resistor into the MAF's IAT wires in order to get it to work
