I'm pretty keen to up the compression ratio through a DFZ bottom end/DKZ head combo, and probably a longer duration cam. I suspect the standard ECU on my S1 205 is not going to be heavily affected by an increase in compression but may be wrong (any one have experience here?), however am a little worried about the dicky nature of the stupid air flow meter flap.
In short I'm wondering if anyone has run a DFZ/DKZ with stock ecu and ignition successfully? If not, what gear have you used to make it work? I'm guessing spark timing will be the real issue in the battle against ping.
