Is the S2K ignition timing in adjustable?

Does the S2K have any sort of knock sensor?

I don't think so, but maybe someone out there with a service manual can check...

Timing is only adjustable within the ECM, yes there is a knock sensor.

Thanks...

Follow up question:

Do the Mugen or Spoon ECM's alter ignition timing?

Luis

According to King Motorsports the Mugen ECU alters timing and fuel map. I'd suspect the Spoon does something similar.

I have a lingering question in my mind: wouldn't the higher CR in the JDM cars require different ignition parameters? If so, how do aftermarket japanese ECUs deal with ROW cars?
