i was just wondering if its true that your ecu must learn your car then how come some people say its good to take your ecu fuse out once a month and let it reset?

 

Only if you have high enough octane.

 

Is this due to the increased acceleration rate and its need for a faster burning fuel or is there something else that I am missing.

What octane levels are common for your premium fuel in US? I believe our top range pump fuel is 98.

 

The Mugen ECU runs lean from what I understand and this can cause pinging and detonation if high octane isn't used.

I want to say that the engine runs hotter when leaner and can result in ping/knock/detonation so therefore cooling mods like the mugen/spoon thermostat, radiator cap, switch would also be needed along with higher octane gas to keep the car running properly with the leaner maps. Anyone more technical feel free to chime in.

In the U.S. (depending on region), octane ratings vary. In California, we have 91 octane as the highest with a few places and other states offering 92+ and race gas nearing 100+.

Here's some general octane info from the Federal Trade Commission, a U.S. government entity.

Have any body use the mugen ECU as a daily driving ECU, And how may click have you put in it, did it have any problem??
