Dealer Recall Surging Suggestion

[glynnk]

Got the recall update done last Friday (August 7th) at my dealer 40 miles away. On the way back home I noticed a "surging, hesitation" between 50 and 60 mph and also at some lower speeds. Called the dealer when I got home to set an appointment to bring it back to have them check it out. That was today, August 14th.

Tech test drove it and said that I needed to burn premium in it instead of regular and suggested a fuel additive also. Then the tech mentioned that "they (presumably BRP) won't tell you this, but after the recall correction you should burn premium grade gas in it".

I'm not sure I buy it. Have any of you heard this?

Never heard this excuse, but after my recall, I have been playing with the Juicebox some and am almost back to running good. I am surprised to find I needed to lean it out a little more than before at midrange, to make the surging stop

Here we go again. Before this rumor gets out of hand, would someone on this forum who has direct contact to BRP get the true story? Lamonster? Tony Young? Other BRP sales or tech reps that are on the forum? Thank you in advance for addressing this before it goes too far.


[garythebadger apologies for the tone of this message. Please read subsequent posts below]

I resent the tone of your message. You think I'd make this up?

[GaryTheBadger]

Absolutely not and I apologize for implying that. There's simply too many rumor fixes on this forum. Nothing personal at all. My message was focused on the premium fuel statement from your tech, not that you passed it on to us.

So, I just called your tech (thanks for the # in your PM) and he confirmed that YES, the official recommendation is to use Premium fuel, not just as a result of the steering recall programming, but because its in the owner's manual to use Premium fuel anyway.

Again sorry about my earlier message. I usually get to know someone before the accusations start!

I don't think you made it up - but I think whoever told you this was mis-informed.

This engine isn't high enough compression to require Premium. Low octane will cause knocking. Are you having knocking? If not - then you don't need premium.

Most of us that have tried running premium have found the spyder runs WORSE. They might have really thought you had some bad gas - hence requesting using an additive.

Remember - more octane burns worse - thus requires higher compression.

I don't believe you can change the fuel maps enough to require a different octane of gas.

 

[glynnk]

No "knocking" or run on like you get in an auto. I'll have to check my owner's maual, but I thought it said put regular fuel in it.

I agree with most of your explanation, only correction: premium gasoline can tolerate more compression before igniting prematurely (that is what knocking is, ignition before the cilinder reaches full compression). All grades of gasoline burn the same once ignited by a spark.

Another thing: the ownwers manual (at least mine page 27) recommends regular gasoline (87 R+M/2)

Well, well, this is interesting.

Glynnk, as I said earlier, I just got off the phone with your tech "Mike" 20 minutes ago and he said the owner's manual says use Premium (and that it will correct the hesitation resulting from the steering update). I'm looking at page 119 of my owner's manual and it says Regular.

This is what I mean about rumors.

Yep, makes you question the tech's knowledge and integrity if he says that BRP recommends premium fuel in the owners manual and anyone can check and see that the manual actually recommends regular. :dontknow: Maybe BRP has a new manual and spec recommending premium but they are doing a very poor job of getting the info out to us owners. My service tech did mine and my wife's software upgrade a few weeks back and he never mentioned anything about using premium fuel.

Sounds fishy to me also. Why would BRP put out an upgrade that knowingly made a Spyder run worse unless everyone started buring premium in it and then not tell us to do it?

 

[SpyderGirl]

The only reason I could think they would suggest a higher octane fuel is due to the "fact" (unconfirmed) that the fuel remapping appears to lean out the fuel mixture which could lead to possible detonation which may be corrected by using a higher octane fuel. Correct me if I'm wrong.

 

[Lamonster]

:dontknow: 10.8 to 1 seems like pretty high compression to me.
My M109R runs 10.5 to 1 and it recommends high test only.

I think what they have done on our motor is back off the timing to allow for the lower octane fuel. I've run it all but for the last 20K or so I run mid and high test fuel in the Spyder and it runs just fine.

I haven't heard anything myself from BRP about running high test now since the update. I don't know if it's true or not but if it is they need to tell all the dealers the same thing. My dealer made no mention of this yesterday.

As I stated in another thread, I had mine done two weeks ago tomorrow, and after approx 300 miles, it is now starting to sputter, backfire and miss. Ireally notice it sputtering/missing around 20 mph to 35 mph.
Can just the fuel update be un-done ?????
I want it back like it was :gaah:

 

[M2Wild]

Can someone post if the premium fuel help resolving the problem?!?!?!?

Hesitation

My spouse and I purchased an SE5 at the end of July and have begun to experience the stall/hesitation in the 50's area. I run 87 as the guide indicates. I'll continue to watch this thread and technotes from the dealer about any further findings on the subject.

It's definitely annoying to say the least.

 

[Big Arm]

welcome luhauc :agree:

I notice my running ruff between 3300-3900 RPMs, don't matter the speed or the gear.

 

[nater1]

Get your TPS changes out. Sounds like something that I had.

I would like to chime in with a note to have the tech check your TPS. In all the years I have worked on engines I have never heard of fuel causing a engine to surge. Unless it is ether. Tell them to check the diagnostic point, and the TPS through the range of the throttle.

One of the major repairs, digging into when my spyder was having loads of trouble was them dialing in the throttle body, and the TPS.

Tell your Tech to call Carlo, and get the details of my repair so you get on the right track.

Same here.
