Can you say who’s tuner your running

 

I may be wrong in my thinking I do not want any folks to feel I am tossing them under the bus. My hope was to see if those codes are common for folks that are running tunes. This tune in particular spoke of a 17-24hp gain as well as other benefits.

 

You shouldn't be throwing codes. You're not necessarily throwing them under the bus if you're looking for help and they aren't responding. Lots of knowledgeable folks on this forum and many with contacts, maybe even one that will help you. Is the vendor a regular on this forum?

 

The brand matters. On my AA stage three is not necessarily “no modifications” it takes waste gate adjusting, it recommends a billet BOV, clutch work, charge tube, and after market exhaust, it also needs 93 octane gas.

 

You're getting O2 codes. I would be curious if they are wanting you to bypass the O2 sensor, which isn't common anymore.

 

No they have asked me several times are you all stock and do you ride at high altitude, about 600' above sea level here and my machine is 100% stock and I have never had any codes until I flashed the ECU.

 

Does your tuner have a different program for black O2 sensor wire or blue O2 sensor wire (wide band) I know the AA has different programs depending on which type you have.

 

No it does not just the stage 3 tune and only requirement is 93 octane, wonder if it would make a difference if I used no ethanol gas?

 

What the heck it has been several days now with no response from my last communication with them here is the tuner.

I am going to guess it is not the tune but more just a coincidence that it happened after tuning.
There are 2 things I would suspect ...
1... O2 sensor is bad or going bad this would be code 3056/4
2... Fuel pump is getting weak and needs to be replaced. This would also explain the Lean condition code 520344/17

It is very common for the O2 sensor to fail. I have had several go out. These 2 codes go hand in hand
I would start with the O2 sensor it is quick and easy ...if you know some one that has another machine you could borrow it for a test .
Your 2018 will not be the Blue wire O2 ..just the standard O2.... Polaris Pt# 4016021

Do not disagree at all here but I do have my stock tune on now however I have not ridden since this tune has been put back on. With this stage 3 tune it really does suck the fuel so maybe it will run lean and will be fine with stock tune indicating a weak fuel pump?

 

Well let us know if throws a code with the stock tune

 

Rode yesterday the machine sent codes immediately with the stock tune. Will replace the O2 sensor first then the fuel pump just seems odd to me never had an issue and within a couple of hours with this tuner I have issues. One last thought is I am using these guys "stock" tune I am thinking about going to the dealership and having the actual Polaris data plugged back in.

 

It should have downloaded the stock file / tune ...so the stock tune should be yours.
I would start with the O2 sensor ....if for some reason your Polaris dealer doesn't have one.. the Indian motorcycle uses the same O2 same part number ...since there Polaris as well

 

SuperATV sends the tunes you purchase plus what they call the "stock" tune, I just replaced the O2 sensor with this one I got off Amazon started the unit and had the same codes so I flashed it with the stage 3 to clear the codes but after a few minutes of idling they returned. Called the local dealer they will flash the ECU with what I am hoping is a 2018 XPT code for $65.00, guess I will go this route to see if I can clear the check engine light.

 

I have the same tuner and no issues. Stage 2 though

 

Are you verifying the O2 wiring harness isn’t chafed or cut?

 

I'm gonna bet with a stock tune it starts working again. No real reason, I've just heard of a few corrupt tunes come from SATV that have been resolved with a factory reload to factory stock and then a new tune from SATV. In fact, for sure keep listening to the other guys suggestions. But I'd sure want to do an ECU swap before I did anything else...

Yes, tuners drink fuel. In the quest for "most HP" they tend to go really rich to both deliver that last possible HP and buy themselves some breathing room from ping & etc.

I don't give two rats asses what SATV said about not needing anything else: Any credible stage 3 tune should include at least a cat gut from the muffler and AA's wastegate adjustment.

Yes, Ethanol makes fuel burn worse. So does excess octane. AA will tell you he prefers straight 91 over 93 ethanol in his stage 3 tune if you ask him.

Good luck!

Running rich actually hurts horsepower. They do it to error on the side of caution because lean will lead to engine damage.

 

3 is maybe to much for all stock, drop down to 2nd stage tune.
