Dobeck TFI Tuning? Problems
#1
Right from the get go, my quad was running like crap. Rough idle, back firing idle so high i couldnt shift it without grinding. And yes I had it installed right. Did everything the video showed too. Whats the deal?!?!??! Did i just waste $200!!!

You need to fiddle w/ the pots it looks like, I have no idea where to start as far as settings, The only thing their site has is for a Polaris 800 and it's settings are Green 2 Yellow 3 Red 3 RPM 7. Good luck w/ that one. I'd call them, it just sounds like you need to adjust it.

Well you need to fine tune it before you go out and give it hell, cause if you run too lean for too long you'll chunk that motor. Just go through their forums, they've got a full tutorial on tuning system. I dunno if yours is a open or closed loop system though. Hell call them on the phone and see if they'll walk you through tuning.

yeah i talk to derek, he helped a little. im gonna play with it later. dont think its running lean, you can disable it by tuning all the screws to 1 oclock. we'll see wuts up

well i think im getting there.set green and yellow to 230-3 oclock and the red to 1 oclock and set the rpm, seems ok but didnt add too much power. still got some playin to do. any thoughts?

I was told the dobeck only adds the 4.5 hp if you remove the snorkle in the air box ..and then adjust the fuel mixture up. Without doing this I've been told that neither the power commander nor the dobeck will add much to the power.
The answer is in the timming... but the timming module is not out yet, and I don't know for sure how long until it will be... but that should make the biggest difference!

Funny you think 4.5 would make a huge difference. Any issues removing the snorkel? Has anyone done a muffler yet? If so are they alot louder? I have a twin air filter on the way, will that help?
