Not likely. When and if I own an etec it will remain bone stock. There is thousands of them out there with happy riders at the pinnacle of 2 stroke technology that just ride, no tuning required. As close to 4 stroke gas and go as you can get. Why would you want to alter the sophisticated DI system? I agree with that saying " It doesn't have to be difficult to be good".
I am quite surprised on the bold. Say you bought a new 2015 ETEC 600, never checked the plugs as you say, then it burned down due to a lean failure. Would you say it doesn't matter I have a warranty? What happened to all that sophisticated technology that you spoke about? If you would like to argue that it has a knock sensor, I will save you time and respond that it used to protect itself against low octane and not extended lean conditions. The muffler temperature sensor is what is used to protect against a lean condition, but that's still playing with fire, literally. 800C (1,472F) is when the ECM detects the muffler is overheating. This is pretty much standard across two stroke sleds. Before it reaches this temp the ECM will go into a fuel enrichment mode. The ETEC has the advantage of adding oil to match the increase in fuel, which is great. But riding these conditions for extended periods is not good and won't help the life of the engine. There is also the oil ratio equation. Your new sled will be setup from factory to run the appropriate amount of XPS Synthetic oil, but it is still your responsibility to monitor oil usage. What if your sled delivers 10 percent less oil and 10 percent less fuel for whatever reason, and runs with 10 percent higher muffler temps? Will you waste your time blaming Ski-Doo while waiting for a new shortblock?
Your best engine is your factory engine with brand new parts and this is worth paying attention to. This is one reason why I am a proponent to getting the fancy gauges that read the muffler temps. If you decide to plug a fancy accessory, you also want to monitor voltage. It doesn't need to be complicated.
Now if you want to pull the Ski-Doo engineering card on me, I will be happy to pull the Ski-Doo engineering history and there are many. In 2003 the 800 SDI was as you say,
at the pinnacle of 2 stroke technology. What do think happened to those engines? In stock form they failed and Ski-Doo stopped making them shortly after. Ironically those engines are the most sought out engines for their cylinders in Ski-Doo history. Most don't even know of their value or how well those engines performed, an even less why they failed.
What I'm trying to say is that if there are any signs of trouble with heat, wether it be coolant, or muffler temps, or troubles with oil consumption, or troubles with fuel consumption, or trouble with the electrical, a blind fold with the words pinnacle of 2 stroke technology broidered onto it won't change a darn thing for reliability. Most people call it.......luck of the draw. Well you and I both know that luck doesn't play into it as much as it is advertised.
Here are some of things we can do with newer sleds. When we are riding with out buddies we can compare fuel and oil consumption, coolant muffler and clutch temps, and voltage. Folks do it all the time with fuel and coolant temps, so it's not a stretch to do this with the other variables and follow with appropriate action. If a problem is found with say fuel or oil, then we have the choice to switch sleds to eliminate the variable of rider style - read throttle control. Then if a problem is confirmed the sled can be monitored against a benchmark. It can and should also be brought to the dealer, but we play an important role, especially if the problem doesn't get resolved quickly. Read the multiple power fade topics for a refresher. That is where a forum like DooTalk comes into play. We don't need to pack our sleds full of gauges to go riding stock sleds, but we do need to be conscious of the needs of our two strokes which haven't changed a bit with the ETEC. DooTalk is an extension to Ski-Doo engineering, one that if used wisely makes a HUGE difference. Believe me, Ski-Doo does pay attention to the chatter.
