  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Non scientific MPG- 2013 TE449

This MAY be interesting or relevant to you, if not, sorry I wasted you time.

My 2013 TE449 is (for all intents and purposes) stock. No airbox mod, stock exhaust, no JD tuner/ PCV, no ECU mod etc. Really the only mod is the ZIPTY oil recirc (which I love)

I was wondering about fuel economy, since I commute on my bike, and follow the same route, the distance, elevation changes etc are stable.

I rode to/from work twice with the "power up plug" installed, distance of combined town/highway for approx. 49 miles, I used 1.941 gallons, about 25.24 MPG

Next, I rode to/from twice with the "power up plug" removed, I used 1.212 gallons, about 40.42 MPG.

Each time the distance was very similar, and I filled up to the top of the gas tank threads from the same pump at the same station.

I realize this is very non scientific, and I didn't factor in the outside temperatures (air density), humidity, etc. BUT it has been nice weather all week, and the same clothing was fine for every trip.

I also didn't try to accelerate at the same rates, or even try to hold the speeds on the highway exactly the same, I just rode to work and back, in my typical manner.

Thanks.

PS, I realize engines running a lean fuel mixture, tend to run hotter, but I didn't sense any EXTREME difference
 
I'm getting 43mpg on a SMR511 with a Akra slip on, TC airbox and map 3. Don't think my mpg has got worse from when it was stock
 
Seem relativley scientific :)

No suprise 'Racemap II' is less efficient though, it runs richer open-loop mapping designed for more power & not as much regard for emmissions.
Using the o2 sensor on Map I, the ECU tries to get the mixture to be as close to the theroetical perfect mix of 14.7:1, not make power.
Good for you if it runs well enough to ride without stalling etc.
 
I have a 2013 TC449 completely stock and under desert racing conditions I get 25-30 mpg and as much as 36 mpg trail riding.
 
I get about 120km to a full 8.5lt tank in our local trails..... about 35ish depending how much left in reserve. Although, the last run was much less, more full throttle work.
 
Alright this is not very scientific either but this is what I have found on my TE449. I would consider this to be real world conditions.

On a 117 KM trip I drove there with the power plug removed. The trip was mostly tight forestry gravel roads. When I got to my destination I filled my bike up. It took ~5.5 litres. Before heading home I put the power plug back in. When I got home I filled it back up and consumed ~8.2 litres. So I guess a person could approximate from there:

Stock Lean Map=4.7L/100km or 50MPG
Race Map 2=7.0L/100km or 33.6MPG

If I am being really un scientific I actually tried to run my bike out of gas this past summer. My dad was following us with a 4x4 and was packing fuel. The idea was to run the bike (and my girlfriends Honda) until they ran out of gas totally. Unfortunately at 126km we had to go separate ways from my dad as he was not able to go down a particular trail. I had to fill both bikes up. My bike still had half of the small translucent tank left ( I guess about a litre) remaining.

Oh I should also mention that my bike had the stock decatted muffler and the evap can removed.

My bike runs the Aus supplied Akro slip-on muffler, no second butterfly, jumper installed & repositioned TPS setting for richer delivery to stop flame-outs & factory 15/51 gearing. No other engine related mods.

As long as I can make reoughly 100km before refuel, I'm sweet in our local areas.
Our longest common ride is from one town to another via steep & twisty forest trails & single track, there is fuel avail there & then we return.
 
I get about 80 miles to a tank....well...to the low fuel light...sometimes 90. If I recall. I never remember to reset the trip thing then it resets itself every two starts.

Huskylove, my trip used to reaset all the time from new as well.:banghead:
It pissed me off because I never knew how far I had left in the bush before running out of fuel....

It never resets now that I have my SSB lithium battery installed.
The original lead-acid battery was in good condition, but dropped too low in volts on cranking when the engine stalled on TDC.
The new battery doen't care one bit & I haven't had to reset the trip or clock since I put it in!! :banana:
 
I get about 30 mpg trail riding. FMF slip on , Map 3 , TPS repositioned . I haven't ridden the bike with the map 3 removed since it was new and don't ever care to again . I need the power on the trail to be able to wheelie over obstacles
 
It never resets now that I have my SSB lithium battery installed.
DM how long have you had your battery , mine would be 6 months old and I keep a trickle charge on it but it still losses voltage if I dont have charge on it for a week , had to jump start my bike bloody no kick starter.

The TC ecu has a map loaded even more radical than the BMW#3 in fuel metering and ignition curves. I piggy back a pcv on to of the TC449 ecu for an average of 20-22mpg.

Mine is about 8 months old, never needs charging. (Sometimes 3 weeks between starts)

My bike is a 2011 bike with a separate ignition switch.
I would check with a multimeter that ALL your power circuits are off when it is parked.
Disconnect one terminal from the battery, switch the multimeter to amps, connect one lead to the battery terminal & the other to the lead to complete the circuit. You should only have points of an amp draw.... i.e. something like .1 or .2 amps as back-up memory draw.
If you have more something is still running.

If it is ok & still goes flat, have a talk to SSB, they have a 2 year warranty.:)

Cheers mate will do . Just seems a little strange ive always keep it on trickle charge and I take it of for a week and nothing . will keep you informed.
 
In powered up mode I was getting just over 105km to the tank (about 33 UK mpg).

That caught me out, so reverted to standard setting and stock pipe, and am getting 45 UK mpg, or 10 miles per litre.

Have a nomad #10 tank on order, so hoping my range will be 120-130 UK miles, as its off to Portugal in October :-)
 
Did a short street ride, stock TE449 with jumper. Went exactly 40 miles and put .994 gallons in. I'm calling it 40 MPG with about 10 miles at 35mph, 10 miles at 45 mph, 10 miles at 55 to 60 mph and the rest in stop and go traffic.
