    Question Unichip A4

    Guys anyone familiar with Unichip. The deal is i have an A4 im doing for a guy at the moment and the thing over boosts when cold ever since it had a new temp switch fitted, which it needed as the gauge was reading incorrectly. Does any one know what resistor i should splice into the ecu line? to trick the ECU?
