  • Audi s2 3b (rs2 spec chips) car won't start help

    Please could someone give us some direction on these so called Thomas schmidt chips I purchased
    Was told the chips was to be used with using the origonal dizzy and 3b pinouts
    One fuel chip and one map chip
    But changing origonal to:
    Pro alloy intercooler
    3' exhaust
    Rs2 manifold
    400kpa 3bar map sensor in ecu
    4bar fpr
    440cc green gient injectors
    Rs2 turbo
    The chips are installed correctly, the fuel pump does not prime and the car won't start.
    I have another 3b ecu that is std and it ran perfect with stock electronics.
    Am just worried the chips are for rs2 pinouts this maybe why it won't start.
    Just hope it has not damaged the ecu!
    I just wish I just got it mapped from scratch!,
    As I do need it looking at once it's running as the turbo is a hybrid
    K24 7400 (volvo s60r) with porsch 944 k26 #6 hot side so the map may need altering slightly.
    Sorry for all the info
    Cheers

    If you can see the numbers on the chip you can check if the fuel chip is for dizzy or 5 coil. The later ECU uses a fuel chip with twice the amount of memory. Boost (MAP) chip is the same though.

    ABY/ADU chips
    Fuel 27C512
    Boost 87C257

    3B chips
    Fuel 27C256
    Boost 87C257


    S2 Coupe 3B Project


    Ur quattro restoration

    S2 Avant

    Boost is the new rock and roll!

      Ah that's good. When I get it back I will check the numbers. as I have sent the ecu to someone who is putting another es tuning map and changing the map sensor to suite.
