Speaking with a recent purchaser of a
9 ner today he's picked up a rather nice 08 plate
in Red 12K on clock Fuel cans etc
Asked him about the Slow speed surging / Air box mod etc
Nope he says I've got wee box that's sorted all that

Hmm never heard of one before. I guess it's a sort of Power Commander type of thing?

Yes and no. The Power Commander is inserted after the ECU and changes the control of the fuel injectors. This gizmo is inserted before the Power Commander and changes the signal from the lambda sensor to trick the ECU to change the fuelling.

However, Power Commander can be extended with an Auto Tune unit, which will ad the same functionallity (ie adding the Lambda sensor signal to the equation)

 

Cost is about the same as the Power Commander.

Autotune only works on a PC V so you can't fit on to a TDM as there's only a PC III available for it unfortunately.

 

Also it doesn't use the bikes lambda sensor, you disconnect and install the Autotune lambda sensor which feeds into the PC V and you can adjust the trim maps as well as the fueling maps - I had one on my FZ1 to build my own maps.

It also can work on the fly and adjust fueling according the trim maps you set up.

 

It's a decent set up and probably cheaper than going to a dyno guy, however it's time consuming and I wasn't happy with the overall process, but once I'd got a couple of maps down I sold it on for a decent price, so it's quite cost effective once that's factored in.

 

I do quite like the look of this idea though, working off the lambda signal and adjusting real time for it is not a bad idea and avoids the need to disconnect the sensor altogether for the correct running of a PC.

It's perhaps worth bearing in mind that the O2 sensor is not monitored all of the time by the standard ECU. Under heavy load, large throttle openings the ECU goes into open loop mode. I am only mentioning it because some people think they will get more horsepower. The O2 sensor is normally mainly implemented during cruise conditions and at smallish throttle openings.

 

You can always set your mixture to ideal highest power ratio by opening the throttle quickly :)


900 with better bits. Owes me nothing, Makes me smile
