Dyno Tuning Hayabusa

[Jet09]

I've resently been able to test drive the Hayabusa powered Buggy, and alltho there's more than enough power, I have got a powercommander attached, and I want to Tune it up. Whats the best way to go around this? Do i need to find a place who can Dyno tune a 'Car' via the powercommander?

I'm in Perth Western Australia.

Cheers

Take it to a dyno that has a wideband O2 Sensor at the dyno.A 4 or 5 gas analyzer is too slow to map FI curves..

How's the riding in Perth?

My thoughts...

A dyno is used to tune by setting the AF (air fuel ratio). You can get that ratio through the use of an O2 sensor. IF you could log the O2 versus RPM while under hard acceleration, you'd pretty much have the same thing as a dyno.

Check this place out:
AEM - Sensors and Connectors

I used one of their products sucessfully to tune my carbeurated engine. I didn't log, I just watched the ratio to see if I was lean or not.

The dyno is the best way.It analyzes at a controlled rpm rate and load.I'm not saying that you can't tune it close with the use of onboard datalogging such as Innovate products logging hardware.Hell I map my t'bo busa that way.The dyno will get you closer to best though.

Of course you could also take the easiest way and just load up one of powercommander's ready to use maps if you're talking normally aspirated stock engine.
