I just got my general (2017) a few weeks back, and after a creek ride, my check engine light came on. It kind of put the machine in "limp mode" (I couldn't get it to go over 30 mph.) I Took it back to the dealer, and they said it was some sort of a drive shaft sensor (I could be wrong about exactly what it was but, the light didn't come back on after the repair) which they replaced. Today, the light came back along with the two codes listed in the title (65590 and 65592), which, after a bit of research, I found to be something with the spark plugs. I pulled them out, and they looked brand new. I blew out the chambers, plugs and boots and will ride it again tomorrow to test it before we head to Brimstone on Thursday. Any other ideas as to what these codes mean? Any tips would be appreciated. Also, if the check engine light comes on, the performance returns to normal if I turn the machine off and then back on. I will be calling the dealership Tuesday for help, but I wanted to ask here for a quicker response (my local dealer is closed Sundays and Mondays). One more bit of info, the creek ride referred to earlier was some splashing of water....no deep holes and nothing over the wheels.
Check engine light with codes 7 65590 and 7 65592

Might be working as it should and you really have a misfire, or something might have happened in the clutch to cause rpm to not match what the computer thinks is correct for the speed and trip it.
Not aware of this happening on any new vehicle unless something is not working correctly
Thanks Todd!, it sounds good on both cylinders and run smooth on idle, and if i turn it off put in low and drive at 3000rpm for like a minute light goes out turn it off and its power again and no problem , very annoying as it happen then i drove it of the trailer then pick it up from polaris dealer the good thing is this forum so i already read about the issue and one way to solve it, Tried first to remove battery and put + and - to drain the ECU that didn't help but to drive in low did

Are you saying it did it the day you bought it at the dealer when loading on the trailer?
sorry to say yes , he told me it was ABS as soon i drive over 20km/h it will go out ,
its just i have over 4 hour drive to the dealer otherwise i would be there already i guess i have to get it to little more closer service station as its warranty
or if they can mail a new ECU to try if its fix it hope fully i get a answer late this week

That sucks
Tobbe,
Having done a lot more research on the Misfire Detection issue...I found that it's not ECU actually looking for a cylinder misfiring. The ECU is looking at the Crank Position Sensor and the Engine RPM. If it senses a mismatch between these signals and call that a Misfire.
There is also a "data rate" involved in diagnosing a mismatch as a Misfire and putting the ignition in limp mode and lighting the Check Engine Light.
Simply turning the engine off and then restarting takes the ignition out of limp mode. Driving a quarter mile or so in L or H will cause the Check Engine Light to go out.
Thinking the Gilomen Innovations program desensitizes the. Misfire Detection by changing the "Data Rate" to something different. Something that moves the data rate that causes the Misfire Detection codes to be thrown and your machine responding.

Giloman sets the parameters in the ECU to the values of a 2015 model XP 1000. Basically there is a range of acceptable values, it is too tight in newer models
Gilomen. $400.00 to flash and ECU? RUK? Thats less than 5 minutes of work. Polaris, get your cranial rectal surgery reversed! What a rip off I gotta say. I understand the frustration of issues but dam 400 bucks for the time it takes to plug in the connector and press start on the computer? I pray my 2022 has none of these issues.

Ever considered the time it took to learn how to crack them? The hardware and software involved, the burned up ECU's during testing etc?
Good King???
Did you actually look at the Gilomen Innovations website?
You can get just the Misfire Detection fix for $220.
The whole package of improvements starts at $400. It does give you the Misfire Detection fix. The others are "improvements"
![Image]()
If none of the other improvements are worth it to you. Then just get the Misfire Detection fix.
To me, everything on the above list has made my 2016 General a better performing machine and that's worth every penny of $400 to me. In fact, I have two ECUs with the Gilomen Innovations programming on board. I bought a fully programmed ECU in April 2018, right after I found out about Gilomen Innovations. And I sent my original in and had it programmed too. Do I need two?
I don't think so, but I had it so I got it done. I've also loaned that spare ECU so friends can try it out for a day. Every one of them has sent theirs in for the full program. It's that good!!
The Misfire Detection issue is very much like the RZR 800 Rear Differential issue. One never knows if it will happen, when it will happen or where it will happen. It appears to be quite random.
I recently got to look at Service Manual for a General model that came with the Misfire Detection right from the factory. Here's what that page reads:
![Image]()
To be perfectly honest, I thought the Misfire Detection had to do with the ECU having inputs to detect a sparkplug not firing.
Instead it's much more sophisticated, using inputs from the Crank Position Sensor and Crankshaft Speed. The Misfire Detection piece of the ECU program looks for that fluctuation in Crankshaft Speed. I can only imagine the time Terry Gilomen spent finding that piece of the ECU program, and then figuring out how to de-sensitize, or raise the "pre-determined limit" so that the Misfire Detection doesn't occur when the situation doesn't really exist. Yet still provide the protection that portion of the ECU program it was to do.
If you don't think you'll have the Misfire Detection with your General and thus you're unwilling to pay for it. Fine. But don't go running a great product, and very talented programmer down, just
because you don't think his effort is worth the money. I sure have plenty of accessories for my General that turned out to be useless and are just sitting in my Toybarn waiting to be thrown away.
Yeah, you sort of pissed us off with your coments.

Buy the equipment and knowledge to tune one yourself. Then try tuning yours and let us know how much you saved... make sure to count all the expenses you incur from your mistakes too...

I'm not sure how one gets to the ECU programming. And how one would find the segment of code for the Misfire Detection...
That's why I sure have liked working with Terry Gilomen!
I have too much to do already without having to learn that! And go through all the learning and use it once?

If it's like the diesel world you buy a program for the "tuning capability" which allows you into the ECU in some way and allows you to change parameters. Basically it's a computer program... Then you buy a sperate license for each vin number which allows you to tune each ECU and then that license is locked to that vin number...

Interesting. In the 2017 that stuck us 2016 Generals with the Misfire Detection issue....I don't know how the reprogramming was done. Perhaps via the Digital Wrench tool?
I'd sure like to reprogram the brain in our 2021 motorhome. Limited to 2600 rpm to make sure it lasts through the 7 year drivetrain warranty. It's got a 360hp Cummins 6.7L diesel. I don't think I'm even able to get 200hp out of it, due to the way the Cummins, Allison and variable vane turbo charger are tied together. Wish I had never bought it. That was Vegas. Got it home to Colorado and Oh ****!

Hmmm...I suppose the way to get to the ECU program is via the Polaris Digital Wrench.
If that will get you into the program...then where is the Misfire Detection portion of the program code and what do you change?
Maybe that's the reason I spoke with Terry Gilomen's Father-in-Law the first two times I called. He told me that Terry was living in the Dyno room!
And that's where he figured out the magic to make the problem go away and figure out all the other goodies you get with his ECU program. How would one go about
getting a Digital Wrench and figuring out all the improvements? I don't even want to guess...a new ECU with Terry's program was worth every penny!!!

A Power Vision tuner allows you to do your own programming, if you know what you're doing. I have played with the one on the Harley a little, very little. I finally ordered my Power Vision 3 with Aftermarket Assassin's tune. USPS delivered it today. Soon as I get home I'm headed to the pole barn. I had their stock exhaust tune loaded in it. If I change exhaust, I email them, buy the new tune, download it to the computer, upload it to the PV3, then load it to the ECU. It has the misfire detection desensitized too. I can buy a multi user license and use the same PV3 to tune other machines. I paid $525 shipped. No downtime without an ECU because it's being shipped across the country. I'll start a thread about my experience with it.
ETA: they have a belt temp monitor that plugs into the PV3 and you can add it as another gauge on the PV3 screen. I might do that later.
