Doo had carbs that were far superior to cats efi system. Crappy throttle response and extreme fuel usage is hardly a trait of a good operating fuel injection system. Ya they had it for a long time. No denying that. I don't know that just because you have an efi system that's refined to nothibg short of manualy dumping fuel into the cylinders before doo had it makes it better. Etec throttle control is as good or better than its previous carb models. I forgot to mention that. On and off the throtttle is flawless with the etec its cool technology. But justifying it is difficultforme and you obviously.
ya ya, :d and Doo's ETEC doesn't get any better oil mileage than the Ptek so mileage wise are we comparing apples? - Doo's carbs might have been superior to the first generations of EFI back in 1993, not in the last 5 yrs. Manual systems (even with engine management parameters like a knock sensor vs fully electronic)? not a chance, even MPEM and DPEM, the HAC was a good idea for the time, Doo gets credit for coming up with a decent altitude system in 1994, but Doo's system comparatively to a full EFI system that monitors far more variables in the last 5 yrs? again not even close. Any system with jets is outdated, computer software is the new fuel delivery method. Hard to argue with all the tech out there for Cat/Poo/Yammy...No one making an adjustable control box for Doo p-tek sleds.....so much easier tuning a sled with a laptop or a few push buttons on the Boondocker box than a Mikuni jet wrench and a handle of parts, slides, jets, needles, pilot jets. The couple cats in our group don't ride out on less fuel than the doo's or yammy's, everyone is pretty close for the same style of riding. Usually I'm the one running on fumes and I have the biggest tank.
Electronics are the future. Go ETEC if you can afford it IMO. As mentioned, better cold starting, no flooding, etc. Is it worth the extra $$$? Depends on the operator, if a hard starting sled a few times a year isn't that big of a deal, no its not worth the extra $$. If you roll it lots or want something that will be more current than the Ptek - yes its probably worth it. Individual preference.
