Default Is the Mugen ECU open loop

I know it doesn't adjust the timing from the knock sensor, just after knowing if this ECU can be pulled back to compensate for normal road driving.

Can the knock sensor be brought into the loop or is it that stripped down it will not compensate for any conditions?

The knock sensor is "cut." It is not available to the user.

I'm not sure what Shipley means? Are you referring to Wordwork?





Speed Limiter = cut
Rev Limiter = 9000 rpm
O2 Feedback = cut
Knock Control = cut
Air Pump = Cut
Air Con(ditioner) = Cut
VTEC = no change
MAP = no change
Wonder what the Air Cond cut means.. it's operation is unchanged.

I put several thousand miles on my cat with no difficulties. It may cause problems if you run it very hard for extended periods.
I changed the original post re fuel map. I knew it was leaner from the dyno but I copied the data from an old post without editing. Sorry for the confusion.
