Dynojet Power Commander V

OpenRoad · Jan 10, 2017

Has anyone thought about getting a Dynojet Power Commander V for their scr950? They have a low end torque map for daily commuters.

Tadlock · Jan 10, 2017

When the wallet allows me I do plan on getting one along with a different intake and exhaust.

It's useful if you've changed out your bike's exhaust system, added a high-flow air filter or smog block-off plates. Then the Dynojet Power Commander V will be needed, but that's around $470 on top of whatever your other parts cost. At least it's almost plug and play and easy to use.

OpenRoad · Jan 12, 2017

I read that a Dynojet isn't really needed for just an exhaust kit, but moreso if you've installed an aftermarket intake system. Anyone have any info on this?

Tadlock · Jan 12, 2017

I've read the opposite of that somewhere, and on my XT250 which is EFI it has lost its 'umph' after I made some changes to only the exhaust.

OpenRoad · Jan 13, 2017

There's so much conflicting information on the internet, hard to wade through everything to find out what's really true or not. But if you noticed a decrease in torque after changing out the exhaust then a re-map is probably needed.

I guess if you notice the bike running differently or richer/leaner, you would get it re-mapped then ? Or you could just wait and get all three components and do it all one shot

OpenRoad · Jan 17, 2017

If you have the funds, then it's probably better to do everything in one shot so you don't have to get it re-mapped after ever new mod.

I typically like the idea of saving up to do things as a whole when it comes to that. But I also love the feeling of installing one part... enjoying it, and then when I get a little "bored", buy another part and install that one, etc.

Found a dyno graph of the SCR950 with the power commander for those interested.

Looks like they smoothed out the power delivery a bit around 4000 rpm, a dip in power is missing which is nice but the marginal increase in both torque and power just isn't worth the cost to me.

Me, neither. I'd rather spend the $ on tires & gas and enjoy the bike as it is. =)
After I installed the small tachometer, I got to see what range my bike spends 99% of it's life and it's nowhere near where all the pipe, air box, fuel controllers & reflashes begin to show a difference.
I'm no slow-poke, but the SCR almost never sees anything much over 3,500-4,000rpm. Cruise rpm at 55mph is only about 2,850.
Top speed? We mustn't kid ourselves. Even digital speedometers can be off quite a bit. The V-Star 950 where this engine came from tops out at just 90mph. I would like to see a GPS verified SCR speed of anything much over 100-110mph. Doesn't matter to me, really.
At those speeds, I think I'd be missing the whole point of this bike. There are better tools for the job, as they say.
Heck, I had a 450 that would eat the SCR's lunch and kiss it's girlfriend, performance-wise. LOL

I may or may not have gotten the stock speedo to read 105....

Either way, wouldn't have any GPS data for it anymore.

Dayum, that bad huh? :wink2:

But you're right. You want a bike to go speeding down the freeway aiming for speeds of 160+, you're looking at the wrong bike.

The 450 had DOHC, Cosworth-designed head and made about 50h.p. It was good for 110mph. If you shifted it where the engine felt smooth and "happy", the tach said about 7,500rpm. =)

OpenRoad · Feb 14, 2017

You start seeing more of a difference at around 4-4.5k rpm and at that point you're really hitting the top end of revs you usually ride in. I prefer leisurely cruising around than speeding down the freeway. High speeds does have its appeal, but i can only take it for so long before it gets tiring.

But if that's your preference then by all means, go for it. I'd be interested to read about the power commander from someone who has installed it, just not something I would do.

TheScrambled · Feb 15, 2017

If I do get the Dynojet Power Commander V, it'll be more for smoothing out the power and torque delivery than the increase in power. That's just not really necessary with the scr950.

Great read, thanks for all the info.

Just one question is the Dynojet Power Commander V still one of the better options if you were thinking of fitting a PC to an SCR ?

Thanks again

Paul · Apr 21, 2017

Ive just got off the phone to Sportsbikeshop.co.uk trying to buy the dynojet power commander V for an SCR.

Dynojet are still not listing the SCR on their main web site as a model they make the power commander for but online there are a few US retailers listing it for the SCR, looks like its def the same unit as for the Bolt.

Sportsbikeshop are contacting Dynojet to find out, as soon as I hear anything Ill say & if I get a correct part number Ill buy one.

If anybody knows of a UK retailer selling one for the SCR please let me know.

Just heard back from spotsbike they said:

Dear Paul,

Thank you for your email.

Unfortunately we are unable to stock your power commander V

It may be worth contacting Dynojet UK as they should be able to assist you.
Their contact number is:- 01995 600500
[email protected]

Just phoned Dynojet UK they dont stock one for SCR at present, I gave them Dyno jet part number I got from revzilla : 22-035 which is for a xvr bolt. Dynojet UK said they are going to check with their technicians to see if that unit is ok for SCR & get back to me.
