    rs2 ECU vs ABY ecu

    Can anyone tell me the main differences between the aby and the rs2 ecu? ive been offered an rs2 one and was wondering what benefits this would give me over an aby one with the mods im planning bearing in mind im going to need a remap anyway
    Cheers

    Nothing really. It only acceps different software and has factory fitted 3bar MAP. They can be modded eighter way ABY <> ADU.

      AFAIK the ADU has a 3bar map sensor and the aby a 2.5 one!
      Go Holset or Go RS4

          AFAIK the RS2 ecu has an extra resistor in it somewhere.

              If you're getting your ABY remapped anyway with all your new custom hardware, I'd not bother with the RS2 ECU as you'll still need that remapped with what you're putting in. Besides, do you know where that ECU has come from? ...
