For the first time I need to disagree with you on this topic Hero. Having tuned bikes for over 40 years. Just break it down as simply as possible. The ECU is the brain of the bike where you can make significant positive changes to how your engine performs. A power commander is simply a piggyback unit designed to assist the ECU. The range it can assist is limited and can become a more difficult addition. Carbureted bikes always will be effected by altitude changes, EFI, bike’s nowhere near as much as the O2 sensor still feeds back information to the ECU to adjust the fuel to air ratio.

Great information though I will pile on. The Power Commander is another part to fail ask me how I know and it will leave you on the side of the road. No reason at all unit had power just stopped working all together. On either the ECU flash or PC if you change a component it is still recommend you reflash in either condition. This was a very well done video and great knowledge thank you.

Thanks for the info brother keep up the great work 👍

I just picked up my third bike, and it is a 2003 Suzuki GSXR 600. I called Chris at Moore Mafia, and he told me that the 2003 GSXR 600, and GSXR 750 can not be flashed, so I was thinking Booster Plug install, it trick the ECU into thinking the outside temp is colder thus increasing fuel output at the points the bike needs. Thanks for putting out another info video!!...I have learned a lot watching.

I've heard a power commander works with carbs... Just kidding! Great video always!

I have a question that I am hoping you or someone can make sense of. My current elevation is 4640. Our current Density Altitude is going as high as 7, 800, (+3, 160 feet). I have an understanding of Density Altitude and IAW scientific Articles of weather, sea level is 0.0764 lb/ft3 Air Density. 4640 is 0.0665 lb/ft3 Air Density. And 7800 is 0.0605 lb/ft3 Air Density. From 4640 (0.0665) to 7800 (0.0605) is in theory, a -9.023% reduction of fuel due to elevation (density altitude of 7800). // If I subtracted 4640 from 7800, that gives me 3, 160 feet. Some people say add or subtract fuel by 3% for every 1000 feet change of elevation. 3160 divided by 1000 equals 3.16 (or 3.16% of fuel change). Is there a way to prove or disprove one of these theories of fuel adjustments? I also understand a car or motorcycle should make automatic fueling adjustments according to elevation. But an elevation of 4640 with a density altitude of 7, 800 is lacking more oxygen than at 4640. And this I suspect is not being factored into the ECU adjustments to maintain proper AFR. Am I wrong? Or am I missing something??

Anybody know a good motorcycle Dyno near nottheast pennasylvania

[riyonkennedy]

Plz do a separate video about auto tune!!!

Changing exhaust is generally losing hp. The engineering in stock exhaust systems is amazing. Back to back dyno on stock to aftermarket will show 1 or two hp increas if lucky most will show a hp lose. But will be louder so people think more power.

In the current day with almost all modern bikes the only self "tuning" option is to change the engine fuel map by buying an ecu programmer. This is not easy (I've done it, trust me, it will not take a day - or a week - or a month). Trusting some other shop to provide a good fuel map is very hit and miss. Some "specialist" shops have good maps - they are the exception. Most are pretty useless.

And by the way, one specific comment. You are right about the default fuel map being lean, especially in the low rpm low throttle range. Now trust me on this - correcting the fuel map in this region makes a HUGE difference to low rpm power and driveablility - and this is one region where a dyno tune will not achieve much. Dynos are mostly not very good at partial throttle / low rpm.

A final comment. Years of experience tuning fuel maps has taught me that one of the most important attributes of a really good fuel map (and of course we are assuming that the fundamental fuel curves are right in the first place) is how smooth and regular the fuel curves are. A jagged set of fuel curves, even if they are mostly in the right region, will always perform worse than a properly smoothed and spaced set of curves. Most dyno curves are not even close to smooth, and this will never deliver optimal results.

What song is playing at the end of the video?

[brentiniba]

hey hero i have 2 options for my first bikes a CBR954RR or a 2015 yfz r3 which one do u think would be good for someone that had experience from 125 and 250

[koqgames]

Does 400CC need to be flashed with replaced full system + exhaust

[GSXRlntensity]

Appreciate all your vids man! Keep’em coming!

[StrawDragon]

Take it to someone that tunes bikes and proves it with a dyno... Is the best way. Youtube shorts video, not 7 minutes...

[halcyon]

If I have a power commander and I later decide to sell my bike and want to return it to stock, is it just a matter of disconnecting and removing the power commander?

[rideroll]

1. Good tires 2. Titanium exhaust 3. better air filter 4. dyno setup 5. change gearing 6. supercharger. Placebo efect for slip on that was used and measured on dyno by manufacturer? I dont think so... Not every exhaust is total china crap

[funnypunny]

how do you know if a second-hand bike's ecu has been flashed? do you bring it to any dyno shop and they will be able to find out?

[IN_ZANE_]

Man stop perpetuating and parroting the internet myth that exhausts always cause a bike to run lean. It's a bit cringe. Truth is that some bikes (yes modern bikes) can actually run rich as a result of an exhust. It depends on which bike. Please do some research if you're going to choose to make informative videos. This video really feels like a placeholder / gap filler to the normally more interesting content previously on this channel, hope it's a just temporary hiccup, love the old content.
