Help for installing mugen Ecu

[Civic Type R]

*HONDATA FTW* oooh dont have a chipped ECU ohhh noooo... LOL jokes.

you might need to get out the timing gun also and check timing with the new ECU as some ECU's wickedly advance the ignition.. these JDM ECU's are tuned for 100RON fuel (Aust premium = 98RON) so you may even need to retard the ignition timing ever so slightly.

if you dont have a timing gun etc - go find the steepest hill you can and roll up it in 4th gear at about 60km/hr and then floor it and listen out for pinging. if it pings you need to retard the timing.

Dont make this confusing.
That may be true for some JDM ECUs but we're referring to the Mugen one.
For more technical advice, speak to Andrew @ RaceTorque.(Perth) They tuned and built my car with the Mugen ECU.
