Will the 1330 engine adjust based on gas octane changes?

[Fjrwillie]

Wondering if the 1330 engine adjusts based on the octane you use like cars do. Think car engines will retard or advance based on the Octane it senses. Something like that. I am not an expert on this, just what I have heard. I don't think motorcycles do in general. Could be wrong on this as well.

I made the change to 87 octane over five years ago. I have noticed no difference in performance or mpg.

I live in AR where ethonal is part of the picture. Been using 87/10% since July of 2019.

I think the EFI system compensates for whatever octane you are using at the time and makes the engine run like it should. You should be ok to go with whatever grade you put in the tank.

Stay away from 15% ethanol. The manual says it will damage your Spyder.

[CloverHillCrawler]

I made the switch after Premium Prices went over $6.00/gal here in Md.

No Issues yet but I am looking for a station that has the no ethanol gas so as to minimize chances from ethanol damage.

In season I run E10 in my toys. When end of season comes around, I start running E0 to avoid issues. Sleds and the F3 will run on 87 just fine but my HD specs 91 minimum.
I can get 90 E0, HD has not complained yet so fall fill ups of E0 are my SOP. Cooler temps reduce octane sensitivity also. My small engines only get E0 as well as the boat.
NO E15 unless it means having to walk then only enough of that to get some E10 or E0

The ECM does the thinking based on the octane one uses.

..... also have been using 87 w/ethyl since 09 ( and recommending it ).... IF - If there is a decrease in performance, I think it would need to be measured using a Dyno .... I have not noticed a difference ..... jmho .... Mike

Based from Can Am Brp website in owner zone they state https://can-am.brp.com/on-road/us/en...otorcycle.html
Summary copied from link:
For Spyder models, your machine will perform to its highest potential and best performance on 91-octane fuel with no ethanol. That said, you will not damage anything if you use 87-octane fuel with no more than 10% ethanol, it just won’t perform top its full potential. Ryker models perform well on 87-octane fuels. Do NOT use E15 or any fuel with more that 10% ethanol in any recreational vehicle as this will damage the engine.

Using the E10 ethanol fuel isn’t all that bad, but letting it sit in the fuel tank and the fuel system can lead to long term problems. Typically, you do not want to leave ethanol fuel in your Can-Am Spyder or your Can-Am Ryker for more than 30 days. The reason for this is due to the water-absorbing nature of ethanol fuels and the corrosive nature of the ethanol. So, if you do choose to use fuel with ethanol, try to add a fuel stabilizer if you will be leaving the fuel in the vehicle for longer than 30 days. If the vehicle is going into storage for a longer period of time then it is pretty much mandatory to treat the fuel with the appropriate heavier dosage of stabilizer to prevent problems when you go to start and use the vehicle.

Pretty timely question considering the price of gas. There is not an octane sensor per se, testing the gas you put in the tank, in order to adjust engine operation. Spyders and passenger vehicles have a knock sensor. So, if you’re running your engine hard, going for that peak performance, and you are using 87 octane gas, you could create the right conditions for detonation. The purpose in life of the knock sensor is to “listen” for this, tell the ECU what’s happening, and the ECU will make the timing adjustment - retard the timing - in order to eliminate the condition. That’s the point where you may not be getting your peak performance. Otherwise, there is no difference in engine operation and you don’t notice a thing. The energy content between 87 octane and higher octane fuel is the same. The knock sensor handles this at just the slightest hint of detonation, long before you would hear it.

And if you're lucky enough to live in NY, you can go to Stewart’s and get 91 octane, ethanol free gas. Wonder what the price of that is these days.

[FrogmanDave]

Yes. And any modern motorcycle (with fuel injection) does as well.

[GFrog]

AT 5:19 on this Smoaks video, you can hear a newer Spyder having some pre-detonation issues. However, the rest of the ride is good except for the warped rotor.

I put 91 octane in my motorcycle. It's 6.9 cents per liter more than 87 and I usually put 20 liters per fill-up in my 25 liter tank. 20X6.9cents=1.38. If I 'm willing to fork-out $35K on a new toy, it's not a $1.38 more per fill-up that will break my bank account. But that's just me.

For reference: 1 US gallon = 3.79 liters

Yes! 24/7 at every stroke.

[linguine]

Howdy do, to all,

Here in Arizona, the best we can get is 91 octane, AFAIK.

So the questions:

1. Anyone ever run 87 octane? What do you notice?
2. Those who can't get 93 octane -- anyone ever use an octane booster?
3. Am I ok on a straight diet of 91 octane?

P.S. Prices in the greater Phoenix are ALWAYS spike in late March/Early April. We have no refineries here, and the Phoenix supply comes from California, where they do the maintenance changeover for the Summer mix. Awful.

If you enter 'Octane' into the Search field up in the top right of the page; click the 'Search Titles Only' box in the drop down list; & submit the Search, you'll see there's already a whole heap of info on the Forum and IIRC, there's even answers to each of those questions you've asked.

That's great for you .... currently in Vermont the difference is .55 cents, not so great for me .....Mike

I've used 87 oct. ( w/ethyl ) in my three Spyders all the time ( except for testing or drag racing ). I have not noticed any loss in power ( although there is going to be ). I also know how to downshift and do so as needed, my 1330 engine gives me 38 mpg's consistently, unless I'm really pushing it ..... Never had any engine issues ..... Mike

[linguine]

Thx. Quite useful.

Since this bike has a Stage 2 ECU tune by WickIt [by original owner], it should then just adjust fine, I think.

[SLICE]

I'm so tempted to fill up with the 110 octane offered at the gas station a mile from the drag strip, but at $9.52 a gallon .

So until I find $70- dollars laying in the street I'll pass, but still tempted

I run stage 2 also. WickIt recommends 91. Check it out. You can't always hear it pinging, but it's your choice. I carry BOOSTane in case I'm out in the middle of nowhere and can't find 91. I consider it cheap insurance.
As BK refers to, DON"T lug stage 2.

[bigbadbrucie]

I went a few tankfuls with 87 octane and did not notice any difference. Then my reasoning kicked in as I’m getting older.... I’ll be 80 in 2 weeks, my eyesight is getting worse, as is my hearing as well as my general health. It started thinking am I missing something? For the original price we pay for the privilege of riding these things, am I going to start two bit-ing for the few extra bucks for the recommended fuel? Right now it’s costing me 12 cents to 13 cents per km for this pleasurable experience. I can afford a few dollars extra for the fuel, but I can’t afford the few thousand $ for an engine replacement, can you? just my own reasoning, take it or ignore it.

110 or 1010 oct .... it's your money ..... neither one will give you any more Power ..... JMHO ..... Mike

Its not about power, but more about engine damage with lower octane fuel. Too much octane can actually make an engine lose power and burn too cool.

Far better than a lean condition and running HOT.

Heat kills.
