    S4 boost control

    Hi Guys,
    I Purchased a hydro with both the black and yellow ecu... looking at the yellow ECU it looks like it has a boost sensor in it... to control the electric boost controller. is this correct??

    if it is will it still boost if its not connected to the ECU... it use to be a race ski and the boost control was the manual style controler.

    With thanks

    You need to have the hydrospace diagnostics cable and software on your computer to change between black and yellow ecus. You only need to hook it up to the computer one time to set tps on both ecus then you can change which ecu you use at any time.

    Do you have the software and cable? Do you know how to set tps?
