Dyno Testing the Can-Am Defender HD10 ECU Flash

So how much horsepower does the ECU flash make on the Can-Am Defender HD10 engine? We here at Vivid Racing and VR Tuned love testing others products to show how they really perform and how we can improve them. This particular Can-Am Defender was just tuned with a competitors flash. With 72HP stock on the 976cc Rotax engine, we wanted to see what the rear wheel horsepower was on our dyno and if we could improve it. CVT transmissions usually have a 30% drivetrain loss when we run cars on our Mustang all wheel drive dyno with 91 octane. If stock horsepower is 72, than crank horsepower is roughly 51 rwhp. Doing back to back testing, we saw the competitor put down peak horsepower of 54 rwhp. This is only about a 6 bhp gain over stock. However if you look at the dyno graph curve on our site (view below), you can see how the power drops off tremendously. So the larger gains are really further in the RPM range rather than peak horsepower. Along with a higher rev limiter and speed limiter, its a nice tune over stock.
We wanted to see how we could improve it. So after letting the vehicle cool down, we flashed our new ECU tune to the car. With changes to the timing and fuel maps, we only gained 1 rwhp more at the peak but had a larger gain of nearly 4 rwhp at the top of our test doing 60mph. We consistently had a 2 rwhp gain throughout the curve. Going past our mph end test, we were able to do 70mph and reach almost 8000rpm as shown in the video. Other features of the flash are the ability to start in any gear, much better throttle response, and improved use of L gear.

I have the HD10 Lonestar edition and love it. Needed 6 seats for the family so went with the school bus. Great overall machine.

[@charlespetersonii6989]

Do you know its top speed? I am looking to get the same! 👍

[@DerangedOffRoad]

Dave is on a plane on his way to Hawaii with the family. He may or may not respond over the next five days but I’m sure he’ll respond when he gets back.

[@DerangedOffRoad]

Charles Peterson II Dave here, HD10 will hit 60 no problem. I've seen speeds of 65 on my machine when conditions are right.

[@philhoffman6473]

Is there a video comparing your tune to a stock defender, instead of comparing to your competitor’s tune?

[@jeremycounahan3957]

You're not drag racing and I didn't see enough difference in the two times to pay y'all to reflash someone else tune.... Just my opinion. Not enough gains to justify it.

[@vivid_racing]

Thank you for your opinion

[@okienightstalker3145]

What is the average rear wheel horse power on the 72hp machines before tuning? 2020 hd10 is claiming 82hp...thanks for your effort making this video!

[@hondarider1112008]

Why wouldn't you run a low range dyno? You would most likely be in better rpm to find power over high range

[@normdickson2438]

Can am defender all the way

[@franksikorski5390]

Just curios how you achieved 89 lb-ft of tq at the rear wheels, when the Mfr only rates this engine at 61 lb-ft??

[@vivid_racing]

We typically only look at the HP gain with cvt transmission vehicles

[@joshualester2735]

On a normal Trans you run in a 1:1 typically. Cvts are always shifting so you're getting torque multiplication. Hp is just a function of torque over time so its a better indicator gains/losses.

[@erickurtz2750]

Well I’m not drove a Mahindra Rockstore but I have drove a canon a.m. so right now at this point I would say a Can-Am defender

[@bigrhino54]

Can-am all the way 👍

[@vivid_racing]

🙌🏼🙌🏼 they definitely make some quality machines

[@mikegray7876]

i would like to see about buying one to give my 2021 hd10 defender limited for hp and were can i buy it and how much

[@vivid_racing]

You can purchase our tune here - www.vividracing.com/tuned-ecu-flash-tune-canam-defender-hd10-dps-p-152476556.html

[@NanceLvr]

What about the HD8?

[@vivid_racing]

Yup shoot us a email

[@mickkeating4400]

Curious if it's possible to get these to do mid 70s and of so what do you recommend to achieve it.

[@vivid_racing]

It should be possible with tuning! Shoot an email over to our specialists at [e-mail]

[@jacksmith375]

Can am

[@adammassalha1224]

is these kit can i use it with can am defender hd 8? i have hd8 with restricted ECU at 60 km/h can i flash it with the same kit?

[@vivid_racing]

Email [e-mail] and our team can get you taken care of

[@randyk2904]

I put dual exhaust on my Defender check engine light on limp mode

[@vivid_racing]

Could be from not having enough back pressure throughout the exhaust system. For more information, you can connect with our tuning staff at [e-mail]

[@swill429]

Is this flash available for the can am defender hd5 model?

[@vivid_racing]

Shoot us an email at [e-mail], we'd love to help you out!

[@wd9581]

This test rig has what size tires with these numbers?

[@vivid_racing]

I think 30's

[@jimcurrier2166]

Mahindra is comparable to a Kubota not a Can Am.

[@flackcat5928]

Can-Am Defender.

[@vivid_racing]

?????

[@christoffswanepoel6459]

He was choosing between the mihindra and the can am
