I saw the mod being touted around and wondered wtf they were talking about. Thanks for the clarification. I had my ECU flashed by you a few months back. I got the 2.5 version to suit the Vandemon exhaust and uni filter set up. The bike is performing really well. Starts immediately even when cold and runs smoother with a bark that really sets it apart. Very happy mate!
Thanks for the test, good to see numbers and confirm what I suspected (that there might be other background maps lurking) I went for a two hour ride yesterday with the switch bridged and it was so much better on the transition, particularly opening up the throttle in sweeping corners. No doubt you are tuning this part of the maps in a remap and I'm sure it will be better if you are. This also works great & is free, freezing the video at 5:47, I can't tell the 0.4hp difference with my Arse Dyno 🙂 Cheers, David.
@frashd For sure. I'm a mechanic who previously had rally cars with Haltech EFI. I understand the layers of mapping needed to make an engine run nicely and correct for multiple things. Also had a bit to do with TuneEcu on the Husky 449 models. I know that bike, there's a nearly flat timing map in neutral to stabilise the idle. That's the kind of thing we're talking about with the CFMOTO that might be hiding in the background - understood. Does feel good from the seat so far, as you say. 👍 David
OK drop in a bit of power, but does it help with the jerky throttle? Thats the whole idea of this mod! I for one would forgo the power to get smoother throttle response.
@exploreR3ality it's mainline. They are the best. You will always have factors that change readings, tyre temp, oil temp, tyre pressure... repeatability is great
Can you please shed some light about the jerkiness happening around 2nd to 3rd gear at 2k - 3k rpm. I am still waiting for an updated version of the ECU from the store. Any temporary fix maybe? cheers
La DSX625 pesa 191 kg seco. La 450 MT 172 seco sin gasolina. Y hay una enorme diferencia en las suspensiones que sobre le DSX son de pura carretera con algo como 145 mm de carrera.
Yes. If you can tell the 0.4hp difference in power just by riding the bike, you're better than I am. @frashd What other things do you think may be going on?
@@frashdOn road on a spirited 2hr ride, I got a couple of cute little pops on overrun downhill into one corner, but exhaust temps seemed normal and nice I pulled up.
@frashd i'd imagine it would be similar, at the last eicma show the specs on the 2025 are identical to the 450mt as far as power and torque at the same rpm.. I'd imagine it's the same set-up 👍
@tennyis28 it's not too bad mate. I thought if dropping foot pegs.... until my foot hit a rock when off road. Longest ride I have done is 6 hrs and it was ok. No harley though.
That makes no sense. Timing won't change. The ecu only adjusts closed loop fueling and commits small term trims to long term. The volumetric efficiency of the engine does not change from a clutch switch. Air cleaner or exhaust (yes)
Interesting test... The reason people are doing the mod, is to 'disable' the fuel cut because of the jerky throttle, not for more power. Based on Facebook posts, it's made a big difference for a lot of owners. Also, your runs (appear to) start at 4000-4500 rpm, way higher than most people have the issues, like when 'idling' downhill on a tricky descent or around town... You don't actually cover what the 'mod' is supposed to do. I understand that it's your business doing dyno maps but you've been dishonest in addressing the issue.
@Paulthenutter34 who said anything about covering the mod. It's as simple as bridging a clutch switch. Fuel cut is not the only thing that is effected when bridge the clutch switch wires. As for dishonest comment..... dishonest about what??? Oh dyno runs start at 2700 rpm. And a dyno run is wide open throttle.
Love your comment on "unboxing"!
Love your data driven approach mate.
Test, record.
Thank you.
@TheSar thanks for taking an interest mate.

@Danger_mouse probably won't feel the difference, just know there is more going on than just decel fuel cut.
@frashd For sure.

Thanks for this mate. Good to know.
Well there you go, nice work 👍
Awesome Work thx 👍🏻
@@Der_Meikel appreciate the comment.
Thanks for doing the video mate
No worries. I like to know myself
Started watching earlier but vid was freaking out 👍

How precise is this dyno ? What happens if you measure multiple times without any mods ? Do you always get exactly the same results ?

Mi like desde España 🇪🇦, al final con todo la moto se pone con 50hp ecu, mas escape, mas filtro? O me espero a la dsx 625 q pesa igual

Is the off throttle behaviour improved? Is this worth the power trade off?
@@fredblogd8448 it's not just the power. There are other things going on in the background that may be happening.
Yes. If you can tell the 0.4hp difference in power just by riding the bike, you're better than I am.
@frashd What other things do you think may be going on?
@@Danger_mouse well clutch in means no enginecload, so no need for comment protection (I didn't check)
@@frashd
Did you mean knock protection?
@@Danger_mouse No, the bike has no knock sensors, I fuel control for component protection
Ciao ti seguo dall Italia ottimo video il pignone da 15 denti
Is it actually bad for the bike or just a little loss of power.?
Not from what I can see unless it over fuels the cat on decel. But I didn't check that
Thanks.
@@frashdOn road on a spirited 2hr ride, I got a couple of cute little pops on overrun downhill into one corner, but exhaust temps seemed normal and nice I pulled up.
would you be able to tune the 450 clc
I can look into it mate.
@frashd i'd imagine it would be similar, at the last eicma show the specs on the 2025 are identical to the 450mt as far as power and torque at the same rpm.. I'd imagine it's the same set-up 👍
Is that the tall seat? Leg room looks very tight
@@tennyis28 yeh it is mate, I'm 6ft 3 though.
@frashd same here, do you find it tight on long rides?
@tennyis28 it's not too bad mate. I thought if dropping foot pegs.... until my foot hit a rock when off road. Longest ride I have done is 6 hrs and it was ok. No harley though.
Grazie x la traduzione in italiano
People are saying you should drive at least 50km so the ECU adjusts to the change. Then you test it
That makes no sense. Timing won't change. The ecu only adjusts closed loop fueling and commits small term trims to long term. The volumetric efficiency of the engine does not change from a clutch switch. Air cleaner or exhaust (yes)
@@frashd How do you even know timing changed? AFAIK you only saw power drop in some ranges
@damaks100 because I have found the ignition table that activate when the clutch is pulled in. That's how.

Oh dyno runs start at 2700 rpm.
And a dyno run is wide open throttle.
Very well described symptoms, i would describe exactly the same.
But i don't think there is anything dishonest in this video.
