Code de7

DirtBoss · Dec 16, 2012

13 800 Pro with SLP pipe, can, PC V, and SLP's clutching started throwing code de7 periodically while headed back to the snowpark yesterday. Ran flawless and without this code on numerous long wide open pulls. RPM's 8,000 to 8,200.

Any ideas Polaris guru's?

Correct. Just bouncing down the road back to the snopark.

No I did not. Sled detuned and then flashed de7 on the gauge.

Got the same at low idle no apparent reason. Maybe bad gas

its saying det not de7 your getting detonation probably low octain fuel or lean condition in your fuel map i would try fuel first

That make more sense! I will check and make sure SLP loaded the right map

Thank you

Witch gas plug are you using? Ethanol or non ethanol?
If you have the non ethanol plug in go with the ethanol plug. It will retard the timing just a touch and could fix your det problem.

I'm running it on the non ethanol setting (adjustable via the gauge on the 13's) and running non ethanol 91. Good idea to switch it and see if that fixes my problem

I can get mine to do this when im screwing around on the trail listening to my damn blow off valve. Just something i can't do. Probably the same with your pipe and PCV probably tuned right untill you start blipping the throttle all retarded like on the trail. At least thats my take on it.

I'm going to see if adding some midrange fuel will help with this as it is happening 3,500 ft and below.

Thanks for the help guys!

I bet its because you are hitting the rev limiter on the hard pack trail. Either add more weight to your mtx weights or live with the potential for the det and bog on the trail... If you switch it to ethanol, it will add 5% fuel across your map making it richer(doesn't adjust timing), which potentially will help this situation, but it is because you are making less power. I would rather add a gram or two to your slp weights...

Update

Talked to SLP this morning and they are building a new map for this setup as other peeps are having the same issue.
According to them it is triggering the det sensor on decel below 3,500'.

New to the Rush. Bought a 2010 600 for my son last year. We own 4 RMk 900's but this is the first rush. He came home today and said he got the de7 (det) code. You guys were talking about an eyhanol plug...what is that. All the gas around here has ethanol.

Thanks

De7 code

I was just cruising down the trail and got the de7 code. The sled then went into limp mode. Pulled over to check things out. Was playing around with clutch to make sure no weights were hung up. After a few minutes the clutch locked up solid. As anybody had this happen to them?

Seems to be a unfortunate common issue with the pros, I my self am battling it - on off the throttle. Usually on or around the trail. However turbo'd., I've read everything from tps to fuel filter, to it picking up a metallic noise somewhere like the front exhaust mount. :juggle:

After reading all of the responses here, No one has mentioned checking or replaceing the fuel filter!!!! I burned one up thinking it was octane problems but was lean because of a restricted fuel filter. Cost me two pistons and gasket set last spring about this time. Old dogs can still learn new things--- fuel filter!!!
