View Full Version : Going from sealevel to 6500' will require a remap?

Does anyone know if will the bikes be able to compensate for that kind of elevation change?

If so, what systems on the bike can compensate for that? There's no O2 sensor in the exhaust...


SXV550 all stock

This was covered a couple weeks ago, the only thing that could help would be a Power commander, we don`t have true EFI.:cigar:

I've run my RXV with the stock map up to 4500ft with out any problems other than idle adjustment. With the Akra map I've had up to 6500ft with the same.

I don't believe you'll have any issues other than the need to turn up the idle a little.

The ECU does have a barometric pressure sensor to compensate for altitude, we run our race bikes all year without mapping changes.
Same map for sea level as the map we use in Salt Lake City or Denver.

I've not run them as high as 6500' so it may be worthwhile to check the A/F mixture on a Dyno.

I have been up to 10,000ft, it runs, just not as strong.:cigar:

Yes but you've got the small motor.:kidding:

the a/f can be cleaned up a little...we are at 7000 or above...get a little sharper throttle response, less fouling.
