2020 Kawasaki Z H2 - Part 6.3 – Performance Tuning Nets 227 HP!

In Part 6.2 of the 2020 Kawasaki ZH2 Project Bike Series, Brock demonstrated the individual power gains produced from adding various high-performance aftermarket components to the once tame Z H2 now sporting the Bren Tuning Moto ECU derestriction flash.

In Part 6.3, using the Brock’s Performance Dynojet Model 250I rear-wheel dyno with eddy current brake, used in conjunction with the C3 Tuning Software with Tuning Link, Brock explains the process of fine-tuning the fueling by allowing the dyno to communicate directly with the Power Commander PCV to precisely match all of these components together. This advanced tuning technique not only to produces more average and peak power across the board, but also increases drivability and smoothness as well as quickening acceleration across all RPMs and throttle openings. As always, Brock does his best to break down this rather technical episode into bits that beginners and experts alike can ingest and enjoy.

All I can say is "Thanks Brock"! You are sharing a lifetime of information and everyone appreciates it! Including the comment at the end. Priceless!

Thank you Brock, as a 2021 Z-H2 owner I have watched this series from the beginning and I am so impressed with the determination and drive you have to see this series through to the end, your content is informative and entertaining and you are very much appreciated in the performance motorcycle community, thanks for all you do and keep up the awesome content. I can’t wait for the roll ons part 2 in Mexico! 😉

184whp/94tq stock to 227whp/100tq....now THATS impressive! Let alone all the other improvements and changes beyond just power numbers alone. i bet it rides sooo much smoother

[SpiritofProductions]

I knew today would be a good day when I saw this video was uploaded. thanks Brock

[whitegoodman]

The beauty of this stage 1 tune is it doesnt compromise the kawi reliability where we have to monitor everything and anything even when we never track it, thats the best part!

[MariusGuitar]

Thanks for this Brock, amazing work and how you bring all of this to us! Been looking forward to this one and of course the next!
I have a 21 ZH2 SE and been riding it since may and the bike is insane as it is, too bad there's so much restrction going on to be legal to sell, but when the bike has so much power I guess they have no option.
Thanks again!
Cincerely, John from Norway

You are awesome brock! thank you for all the hard work and will be buying this tune and full exhaust soon

[gilzr]

Hey Brock good to see you again, love your videos, especially the ones with the Zh2, that’s the bike I’m looking to get this year God will, blessings to you.

[Pdtuning]

Loved when I used to do this on my Nissan GTR and the road having to hold cell by cell to get it when I wanted while I added or took away fuel. And dataloging as many cells as I could and reviewing the AFR and knock levels to make sure I had it right

[shaneee]

Just watched your video on how to lower the front suspension but damn I got addicted to your content. I must say that 86.4% don't know what your talking about but I get the idea. I maybe or not get a great bike like this (third world country) but I'll keep on grinding. Currently owned a Chinese 250cc bike and I love riding and I think that's the part that we all love. Keep the great content up. Love from the Philippines.

Love the videos and I was waiting for this like always... This is one of the reason why I buy ur product to go from stock to brock. My zx14r feels like a monster when I bought the brock flash, got ur map in the PC5, sprint filter, and of course the full alien head exhaust (switch to Penta Carbon muffler) with the brocks clutch mod. Can't wait to watch more...

Still waiting for ECU flash device to be back in stock for my Z H 2.

[greyanaroth]

I just want to say, I would totally buy a flasher tool with brocks tunes for all the bikes you're famous for tuning. Can even be a package with your exhaust + air filter. It can be a flasher tool, loaded with tunes for different fuel types from shitty to race fuel so it'll address different markets with different markets. It's the future.

93 octane KILLER ROCKET!
Looks like I gotta add one more Bike and get the Brocks Genius Level

[daWKin]

Fantastic and informative, thank you for the content.

I couldn’t help but notice the flat towards the top of the Rev range that has persisted since the stock bike - its obviously retarding the timing here so when will you be looking at ignition timing? As mentioned below these bikes love advanced ignition timing and there is more on the table, power and smoothness wise, with it

[chicblair]

Brock, as always fantastic content. Thank you for taking the time to produce the most informative content on the net for us guys 👍🏻 *niceties over* when are you going to crack open a Triumph 1050 ecu 🙏

[stevennelson]

Wow!! That Zh2 is going to Rip!!!🚀🚀just like they should’ve from factory!!! Plus some, because it has the hidden touch of Mr. Brock!!!!🚀🚀🚀🚀🚀👍🙏🏽

[TypicalMT]

Damn ive been coming back everyday to see his “tomorrow test ride” ... been 3 days. I hope Brock didn’t yeet himself into the stars😭

"with a really big girlfriend on the back, going down a steep hill, in the wrong gear" lmao you know someone out there will be THAT person.
