    98 Trans Am Tuner and Fan issue

    Diablo Sport and Superchips only make a tuner for 99 LS1 and forward. Does anyone make a tuner for 98. I read the computer is not compatible...Can i just change the computer for one from 99-02? or is it more complicated than that?

    My check engine light is on saying either fan 1, wiring or its relay is damaged. Does anyone know when these fans should turn on? 1 then2 or both at the same time?

    i think they come on both at the same time, i have never actually looked to see if both turn at the same time, if you only got one running then thats probably your problem

    From what I remember one fan runs continueously and the other comes on as the engine reaches higher temperatures or when the A/C is running.
    I have a `98 and I run the SLP fan switch. it allows you to run both fans at low speed or both at high speed or leave it off so the computer controls them.
