Title: air box and an ECU Post by: aussie on January 15, 2010, 02:05:01 AM hey I was going to mod my airbox, I had a look at the factory ducati modified airbox and I am thinking I will get it, but given how it opens the whole top up and I already have arrow pipes, inevitably it will run lean so any advice on what ECU mods I can do or what ecu I should buy, power commander perhaps ???

Title: Re: air box and an ECU Post by: Howie on January 18, 2010, 12:08:59 PM I thought Trim was just near idle? Pretty much. Trim adjusts the duty cycle of the injector (the time the injector is open). The effect diminishes as RPM goes up, therefore the biggest effect will be at low engine speed. Far from ideal, but a lot cheaper than a power commander and is often sufficient for many owners. |
