Nairnster Posted March 21, 2012 Share Posted March 21, 2012 Ok, so I have done some searching, and found this:After much Googling about resetting the ECU a variety of answers come up. None which seem to fully apply to the MB6 as usual Some of the literature says that Honda ECU's have a fuse that says "back up" or a fuse that says "ECU" and you should remove these. The MB6 has both After trial and error today I got a good result from the below.After getting the car warm I shut her down and took out the "ECU fuse 15A" and the "Back Up fuse 7.5A"Left it 10minStarted the car and just left her idling, you're supposed to leave it till it settles down to a smooth idle, [i left it idling for 10min as the fan activates after a certain point and it gives a chance for the fuel trims to include this].Shut the car down and started it back up straight away. [This is supposed to save the new fuel trim settings].My question is, when do you replace the fuses? i.e at what stage? I presume it is after leaving the car for the 10 minutes?If anyone can confirm this, it would be great, as I dont want to do it wrong.

Nairnster Posted March 21, 2012 Author Share Posted March 21, 2012 Thats cool. I thought it would have to be like that, as I doubt it starts without the fuses. But figured it was best to check lolThanks mate Quote Link to comment Share on other sites More sharing options...

Nairnster Posted March 21, 2012 Author Share Posted March 21, 2012 I figured I would do one out of curiosity, and the fact I am running it on super unleaded, and dont think it was before.Will also be doing another in the next month or so after some breathing/air intake mods.
