Yamaha YFZ450R Big 3 Engine Upgrades, Dasa Exhaust, Fuel Customs Intake and PEP Reflashed ECU Test

Yamaha YFZ450R Big 3 Engine Upgrades, Dasa Exhaust, Fuel Customs Intake and PEP Reflashed ECU Test. For this Yamaha YFZ450R Big-3 Test, we’re pairing up a Dasa Racing exhaust, Fuel Customs intake and a PEP Tuning ECU reflash in search getting the most performance possible out of the YFZ450R as simply as possible.
Rid of restrictions, free flowing and fine-tuned Yamaha’s YFZ450R delivers an easily detectable increase in performance and fun. Working with well-respected aftermarket company’s products that admittedly play well together, we we’re confident in running the Fuel Customs intake, Dasas Racing exhaust and PEP reflashed ECU together and are very impressed with the results.

What’s the most hp you got out of it with this system ? I been tryna figure out which would be best for more hp Rp Racing and Rossier r5 says they have more hp but I’m not sure 🤦🏾‍♂️

Thank you!. Will do.

We had great results with the PEP reflash.. Not a fan of the piggy back controllers.. Great video.. 👍👍👍

Hey Doc, I'm pretty sure you guys did a video on the PED ECU reflash didn't you?

Thats why I love the YFZ450R up to 2013, Made in Japan. Keep the good work guys!!!!. Thanks for sharing

[@ATVonDemand]

Thanks for watching!

[@ossoplu1463]

any reason up to 2013 i have the 2021 model

[@RaVAndres]

@@ossoplu1463 made in Japan vs made in usa. The Japanese model have less restrictive engine (electronics) so modifying it is cheaper. The clutch system is simple but indestructible (you note this more when you race).

[@vintagetrikesandquads4012]

Thanks for the info--never heard of PEP tuning before. I'll be getting a YFZ soon and was thinking about going with Vortex but they are now 800 bucks. I'll give PEP a look.

[@goldenboygq9]

Love the videos guys! So happy you guys have not forgeten about the sport atv crowd

[@MarlonSolisFallas]

Loved this video, subscribed, if only I had enough to buy a brand new YFZ450r :(

[@ATVonDemand]

Glad you liked it. We're happy to have you. Have you considered buying a used machine?

[@chriscallas9483]

That's a real nice setup.Affordable, reliable and even competitive if u wanna race it. Nice! So reflashing the ecu won't affect a piggyback fuel controller like pc5 ? Do they work well with each other?

[@ATVonDemand]

If you already have a PC5 you probably do not need to have your stock ECU reflashed. According to PEP tuning, comma you have a wider range of tunability and features with a piggyback controller than the stock ECU. If someone needs help with their PC5 or a stock ECU reflash, comma PEP tuning can help..

[@dynapatrick894]

That white dasa with the white seat looks sick

[@ATVonDemand]

We like it.

[@hank1556]

I wonder how this would compare with a 'big 3' modded LTR. I love both machines with a slight lean towards the Suzuki

[@ATVonDemand]

We would expect the Suzuki to have a slight edge in power with equal mods. The LTR was a great machine.

[@YetiRC]

The vortex ecu is the best option in my opinion. Completely changes the way it runs.

[@ATVonDemand]

Haven't found anyone that would dispute that yet. But, it's an $800 upgrade plus tuning depending on your set up.

[@YetiRC]

@@ATVonDemand I understand, it might not be an option for everyone.

[@Fox250R]

@@YetiRC You would think anyone who spends 10k on these crap YFZs could fork out another 800 for a Vortex lol

[@lblackburn_6.0]

@@Fox250R why are they crap

[@Fox250R]

@@lblackburn_6.0 The fact we pay 10k for something you have to put another 2k into just to make it run smoothly is ridiculous. And that’s on the cheap side of things.

[@gavinkoppmann2058]

So by sending in your stock ECU to get reflashed, it will eliminate the engine running lean from factory?

[@ATVonDemand]

Yes. You can have it reflashed for an aftermarket exhaust or with the stock exhaust if you want to ride a stealth fighter.

[@vintagetrikesandquads4012]

Got an idea, how about a stage 2 video? What would you do after the big 3, a hi-comp piston, cams, etc?

[@ATVonDemand]

If you're going to go with a high compression piston and a Cam in your machine you might be better off to go with a vortex at that point. PEP tuning can help you with tuning your vortex for whatever setup you want. A piggyback tuner would be a more affordable option as well. Still more capable than a stock ECU reflash.

[@ATVonDemand]

We would like to do a stage 2 like you're talking about. Currently this motor is being rebuilt with a yes slightly higher compression piston, Cam, porting and valve work. Perhaps we will shoot it when the motor is back in. We have some cross country YFZ projects in the works as well.

[@kylebeach2316]

This came across my mind and was wondering if a wiseco high compression piston will work with the 250x/ex motor or will it throw the reliability of the motor out the window.

[@jayemlov]

I love my vortex ecu on mine. Why don't they get used anymore?

[@ATVonDemand]

They definitely still get used. They're just a little on the expensive side. If we were adding more motor mods we would definitely consider one. They work great.

[@tannerjohnson5690]

For the price of a vortex you're better off buying a hi compression piston and cams

Is the yfz450 good for trails and does it like to stall out when going slower

[@ATVonDemand]

The YFZ450R is a very capable trail machine but it prefers to be ridden aggressively. If you are into watching sport quad videos check out our YMZ450R versus raptors 700 R shootout. It does well at putting their difference in performance in perspective. kzbin.info/www/bejne/eGq2Z4RogLaGf6M

[@LolliWANG505]

Even though they don't make it anymore the kfx450r is a wicked atv for xc racing/trail riding. I'd recommend that atv for that style of riding way more than a yfz. The yfz is good but not kfx good.😏
