CB500X power commander?

Hello all, I have a 2017 Honda CB500X. The only thing I have done to it is install a slip on exhaust "Coffman's Shorty". My question is, does anyone have experience with getting more power out of the engine with a power commander? Just was wanting to get a little more from the engine without compromising engine operation. Don't want to damage anything.

Hey Trottman,
Welcome to the forums.
I suggest to use the search function. The cb500 engine is limited by many things, changing the silencer and a PCV would not bring much.
The engine is capable of 53-55 fairly easy, roughly 60 is still manageable, and racebikes can reach 65-66 with compromises on cost and longevity.
Unless you know exactly what are you doing, you'd be better off with an ecu flash than a PCV.

What is an ecu flash? Any recommendation on what to get? Any experience with changing the gearing? Looking for more top end.

I have an ECU R&D company that can flash your ECU, where are you located?

I have a Coffman (baffle in) on my 2014 CB500F along with a K&N and opened up intake snorkel (pre-filter). I installed a Dobeck EJK 3.5. It uses a O2 sensor bypass and has lots of adjustability. So far it's working great. I have gotten a couple of error codes from the bike's ECU when things are on the lean side ("21"...O2 sensor). I've sent off some questions about it to Dobeck and am waiting a reply. It may mean absolutely nothing. We'll see what they say. The power is significantly improved over stock settings. Their WOT (red) suggested setting needed to be significantly richer for some reason (on my bike). I'd buy it again.

I would go with the flash from @PuffTheMagic

Power Commander is more $ and you would also have to get it mapped on a dyno.

We have seen instances where ppl have used generic maps from the power commander site and the bike actually made less power.
