Hey guys,

I have an 01 TT600 with a Micron can and K&N filter. I know everyone says to use the open can map with a non-stock exhaust. I have, as far as I know, the original stock map.

But I live in Denver (5000+ ft elevation), and I am wondering if a different tune is necessary with the reduced oxygen in the atmosphere? The bike runs pretty good except for a VERY slight surge at idle and the lack of power below 5000.

Thanks!

lack of power under 4000 is normal.

as for remap... if you think it drives well,. don't bother to remap. If you think it drives like crap then consider a remap.

Kind of what I was thinking as well... I just didn't want to be running lean all the time and damage anything... Thanks

What you describe is normal, at any altitude, and the ECU should be able to compensate for the thinner air, so if it's running ok, and not too hot or anything you are probably alright.

Slight surge at idle means it's a bit too lean. If you richen it up a bit- a dealership will call it increasing the CO, if you have Tuneboy it's increasing the fuel idle trim value- it will help. Watch the coolant temperature. If it is regularly over 110C or if the temperature keeps rising when the fan kicks on and you are stuck in traffic, it's another sign you are running too lean.

Actually I don't think the temp has ever been as high as 110c (230F). It typically runs (in the heat of summer) around 220-224ish. When the fan kicks on the temp doesn't keep rising, so I guess I am not running that lean. Thanks for the info (again) Will.

well to be honest, what's the worst that can happen. so your engine blows up, just gives you a new excuse to buy a speed four :D
Ugh-- don't say that:eek: I have my eye on a new Daytona but I have to pay off some four wheeled vehicles first! Gotta make it to 2010!

you do know that a speed four and a daytona make four wheels and are multiple vehicles right ;)

i betcha that if you connect some bar or rod between the two you can even get it insured as a self made car ;)
