If the TPS setting is off, say the setting should be 600mv and your at 580mv then the entire FI map will be offset by 20mv to the lean side. Since the system is open loop with no lambda (O2) sensor, that's all it has to go by. The Euro system is a better setup with it's feedback loop (O2) sensor, the extra feedback tells the ECU what's actually happening mixture-wise.
Are the '14's equipped with the closed loop Euro system? I am trying to figure out how KTM has made the '14's supposedly run better stock than with the unrestricted Euro map. Certainly the 350's have much improved bottom torque. When they closed the loop on passenger cars, the average mom's minivan went from 160HP to 225HP! I assume KTM is using common hardware, so if your '12 - '13 ECU is remapped to the unrestricted Euro map, could you weld in a bung for an O2 sensor and get the same magic?

Thanks for the replies, all. I was going the same direction as MasterMarine, so I guess I will press on with that.

Does anyone know if the euro map 2014 "mild" setting increases fuel consumption?

Installed new 13l ktm tank - filled close to brim .
Very slow riding today due to ice and snow still in bush.

Fuel light cane on 167 km, and ole over to mo ran out at 190 km. had to tip bike over to move remaining fuel in wings to get another 2km back to trailer.

I would have thought it would have gone 200km/120 miles.

Switch setting have anything to do with it?

On my 2012 500EXC the map switch only changes the ignition advance. Mild = -2 degrees advance, standard = 0 degrees and Wild = +2 degrees advance.
I notice that the fan comes on more when the switch is in the mild position.
In my experience going slow in the lower gears used more fuel than cruising along it the higher gears. I have gone 114 miles with the stock tank without the fuel light coming on. In an enduro the fuel light came on at 75 miles.

Yes the mild setting does use more fuel. I figured it to richening up the circuit. Got about 120 miles from a tank and should have got 150 or more. Did the same track this year in Baja and had no gas issue in stock map position on switch. Year before had to empty my extra half gallon to make it. I would then think that the wild setting would lean it out? Maybe someone with more knowledge can chime in . I can just tell you that I have noticed higher fuel consumption while in the mild mapping mode.

None of the dirt bikes have O2 sensors, yet.

The 14's run better simply because of KTM's refinements. The engine is 3 years old now and they've had time to get closer in tuning.

Closing the loop on passenger cars wasn't the only reason for more power. Four valve head motors are common now, faster injectors and computers, wide band O2 sensors, higher rev'n motors, 8 and 9 speed autos, and more.

Acerbis 5.3 Gal Tank Graphics?

Anyone know where a guy can get tank graphics for the Acerbis 5.3 gal tank? Be nice to spruce things up a bit, like these dudes.

I'll have a template to customize your own graphics within the next week or so. Same tank and I don't like the bare plastic look so I cut a template and just scanned it for sizing. I have my local sign company print graphics and put 8 mil cleat over it to protect the image. I'll post up shortly.

I am aware of all the other mechanical goodies that have come along. But there was a lot of press on the car magazines the year that there was a big change that lowered the allowable levels of certain pollutants. The average V6 with no major changes internally except maybe cam profiles were picking up 40-50HP. It was attributed to the enhanced engine management systems with a closed loop system. The greens were rather aghast at this in intended consequence of their anti-pollution rules.

You should switch to a 13L tank so I can piggyback off your work!

Graphics don't stay on those tanks, save your money. Take a close look at the KTM video, you'll see multiple shots where the graphics are almost completely unstuck from the tank. I'd be willing to bet they had way more then one set just to make that video. The plastic tanks sweat fuel fumes and the graphics come off sooner than later.

I'm guessing the Altrider will mount the same way the GL Coyote does and so should not present any real challenges, hopefully. I'll load it with a few different loads and try and figure out how much can be carried below seat height. Realistically though I'm betting nothing will carry as good as saddlebags for carrying stuff below the seat height.
