I am wondering what the dealer techs are seeing or saying about this potential issue. I worked as a tech for Cummins and if there was a problem or issue with customers, we always worked hand in hand with mother Cummins for a solution. Is there no reputable techs out ther anyone has spoken to BRP yet? Seems to be a lot of complaints for something not to happen.

I like the 880s far better then the 897 Mach ramps. Thought I mentioned that several times. The drive off and mid is just harder hitting. Mach ramps feel soft in bottom and mid in comparison. I 100% believe they designed them to help with LC, and me along with many others have gone to Dalton Adjustables which work much more like the 880s(depending on how you load them) and still allow the LC to work as my engagement is 3100-3200. I am running them pretty light though.

Going now to the ultimax will change things so I have some items going to order to work with that belt.

I have said this before and will mention it again, because I believe this is just not talked about enough. For anyone here to say he will be back to other ramps, or he will go another direction, ect ect....simply does not understand clutching. 5 guys can clutch the same sled 5 different ways, coming at things from a different approach. And all 5 of those sleds may have totally different components yet all wind up MPH similarly.

Clutching is a feel, and what you want from your sled. My top priority items are likely alot different than others. I loved my Pl/Pl secondary spring for years while most all others hated it. Im a corner to corner junky who wants to ride this like my 850.

And BTW I definitely will be doing a transfer MOD of my own, since this new RmoX IMO is way way too docile, BRP made this sled like that CAT skid and now its the most un-playful suspension I have rode on a Doo.

If you guys think gaining RPMS will make this sled magically MPH that is not gonna happen. We are down on BOOST IMO and fighting a ECU with more parameters than many of todays supercars. Until BRP gives us a flash to get some of these safety factors reduced, these 900r's will never be MPH sleds IMO.

My goal is to get my corner to corner Jam on with some serious clutching. 180/303 and 47 degree start-angle helix aint ever gone do that for me. ECU wont intrude on trails corner to corner, so for now its all about making this a corner to corner monster.

Dan
if you're a corner to corner guy, why do you want the front up in the air? The R mo x corners way better on the throttle than the old setup because of this. You can still seat bounce the front up and over moguls and run them hard.

Do you have data logged on the manifold pressure ?

The bosch PCM in that sled is not more sophisticated than the pick up truck you likely drive to pull your sled, which is really no different than a super car either.

if the tmap sensor has a issue you will get a fault code and you will be in limp mode
the ecu does a test on all sensors at startup

Well my Mach has just arrived at the dealer. Complete except DESS. it's up for sale. I will wait until 2023 release and see what happens. I still have a 2022 900r I will ride for now. I'm a little nervous about resale on the Mach. Dealer sold quite a few and they are all running low on top end and customers are not happy. I think around here there will be lots on Machs for sale soon. So probably easier to sell my 900r x. People don't usually buy them to run big mph.
I think you're right, the value of the Machs is going to tank. With that in mind, I'll help you out too; I offered the last guy $10k for his. Seeing yours is new I'll bump that up to $11k.

These tests are only for gross errors in the readings, like when the sensors(s) are not functioning. Testing 'good' is that the sensor output tests for being within a normal range of tolerance. That tolerance is veeeery wide because the temp sensor can be reading anywhere from -50F (cold first start of the day on a reeeealy cold day) to well past +100F when you start it hot or run it hot. The ECU has no other source of IAT info for any comparison so it can only do a very gross test..

I guess legally they are covered.
But in the minds of us FICKLE Sled Heads, they lost some serious face.

I believe we will find a few tricks to get us to 115 gps & i'll Happy as a Pig in chit.
Oh I get that..... it is more than just legal... it is about customer relations. But because they meet the HP of 180, I just don't think anyone will get any satisfaction from BRP by standing on the 17.4 psi boost thing.

The only thing is to express as much displeasure as one can, and hope enough griping gets something done. Got that. What the most effective path for that is, IDK. Talk to dealer? What is the most effective complaint? Probably the wrong 'effective gearing' that leaves some top speed on the table.. that is something that can be easily fixed and is what BRP might go for.....AND it'll get you better low and mid RPM acceleration too.

Looking closely at what Dan has done, his gain in RPM AND top speed are all technically solid and has a very good explanation. I hope Dan (or any of the clutch knowledgeable guys) will correct me if I am wrong here... I got the engine and controls background. but not on the clutching, so I appreciate what he has done very much. It looks effectively to be putting a higher drive ratio, which makes the top end speed occur at the peak of the HP curve. Doing that is how you get highest top speed.

Anyone have a shop manual for this 900r engine yet? Might have some specs and details on boost levels, inlet air temp ranges, rpm ranges, etc......

Dan,

Have you ever thought of adding the Remote Coupler Block adjuster:


Let’s you run coupled OR uncoupled…..I have one going on my XRS once I get the call that the SDCU/smart shox controller is in (assuming that happens this winter lol).

I thought this would make my sled an XRS/Lynx lol…..

Did Dan not say these weights were showing signs of your clutch slipping?
At the beginning it looked like I had a little slip shown at full shift mark. All in all I really like my stock clutching calibration and how the throttle mapping works with it. I might swap out a sec spring just because I have one to try, but I'm not digging deep into it as Dan is. We'll keep mine as the test mule.

I don't think BRP gets enough credit for making this 900R feel so much better then the old 900T, which needed allot of work to feel good.

190-192 HP from 7400 to 7900 RPM…… come on, a chimp can clutch these 4 stokes with this much torque and HUGE powerband.

Doo advertised 180 HP whether that’s at 13 lbs or 17.5 lbs that is what it is. Manufacturers change specifications all the time.

Guys want the blippy throttle response of a 2 stroke, what you get with a turbo 4 stroke is insane midrange and top end. Yes it’s still the fastest 0-60 ft 0-330ft 0-660ft over 2 strokes but not “snappy”.

Many anticipated 3 things: 1)It’s a Mach Z so it will be the fastest or very close to the fastest sled made……2) The YamaCat has been out for 5 year so Doo knows exactly how fast they have to make it to beat them……3) YamaCat advertised 180 HP too but they are 204HP, that’s what Doo is doing as well.

What a bunch of WHINNERS!!!!!!!!!!!!!!!!!

Bob
That's mean & kinda stings a little, but i'll admit a tad true. When i had 275 hp i wanted more. Never happy
I'm actually very happy with this sled.

BUT let me explain it this way:
You go to the Pearly Gates and get greeted by GOD.
He says you know you've been a good boy and we will let you in, but i owe you an apology.
I FORGOT to give you that extra couple inches on your Junk. Sorry my bad.
You are not going to be happy!
He's GOD so you can't get mad, but you will bitch to some of the Angels when the opportunity arrises.
Cuz as much as i like working on Elevators, i'm thinking a Porn Star would be a much better way to make a living.

Just Sayin'

P.S: If you don't believe in GOD, then replace the character with any Diety you'd like. Don't mean to insult anyone.

Gonna put another 7-800 miles on it this weekend which should test this "needs miles" theory.

When i get back, i'll put on some Bergstrom Rubbers under skis, a BOV then 2 weeks later i'm Back-Packing around Maine for about 2000 miles.
Maybe i'll pick up some Ponies & a few RPM's on the trip.......................................or maybe not
Who care's? I'll be riding...............Wooo WOOOOOOOO

Seen 112 on speedometer and was still pulling, was running out of real estate so let off. only tried for short run due to still breaking in, the rest of time was short burst on trail and rpms were spot on
This is a public relations disaster, I should have known not to buy the first year of any skidoo again.

Brp have got some sleds running decent and a whole pile that are just duds .

Customers are trying there best to figure what’s making these sleds so slow on there own.
By looking for leaks ,ramps ,springs , gears, in stalling boost gage’s , clutches The list goes on spending time and money as there season rolls on with no answer in sight.

These engines are all the same except for clutching. The only other factor I see is the programming that makes this sled run.

This will continue to happen until BRP figures out were they have gone wrong with the programming of this Engine and a update to fix it.

We all know this ECU /computer is loaded up with safety perimeters to prevent warranty issues down the road.( maybe to safe)

Brp should be sending Dealers and valued customers a bulletin or letter stating they are having technical issues and we are working hard to fix these issues .

Time is ticking on this season.

Not always....It can be slightly out of calibration( say it reads 10f high)and it wont code. See this all the time in the auto world
