Buying used Power Commander

[Condi]

I ride a Honda Fireblade 929, which as their first electronic injection bike was notorious for poor throttle response at low revs, and generally a power commander is recommended to help sort it. I've got the opportunity to buy a second hand PC, but one which has been set up with a different exhaust can to what Ive got on the bike. Would this be an issue, or can you simply fit this PC without remapping it?

You can download the correct map for the PC from the dynojet website, it really is easy provided you have a laptop to connect it to, I'd not worry too much about a different exhaust, the difference will be negligible.

Thanks Jaz, not an issue.

I added a PC to my RR6 for the same reason. It made little difference. But disabling the flapper valve made a huge difference. The 929 equivalent appears here:

Interestingly the 2017 bike doesn't seem to have a flapper valve but does have resonance chambers on the intakes.

As said above, its a simple plug and play operation but consider engines do vary and yours is now , what 17 years old at least? To get the best from your PC, a bespoke map is always best, doesn't cost a great deal either.

I've not seen that, thanks.

The fueling on the RR6 is probably considerably better than the RRY - Honda took a year or 2 to perfect electronic injection. Annoyingly.


When you say get a custom map - do you mean take it to a dyno and have someone map it? Sounds expensive.

The Power Commander maps the company supply on their website are not going to be as specific as a map done on your specific bike on a dyno but obviously they are free. Fuel map only (unless you buy an ignition module) either way.

If I ever go down the PC route again I would probably buy the autotune option with it. That way you get it working for your specific bike and don't have to take it on a dyno
