Woolwich flash and predicted range

Now got my bike totally sorted with my woolwich flash and autotune.

Bike is exceptionally fast and smooth too, the only problem I have is the range function on the dash will never give me a predicted range of more than 140km even though the bike usually does 210-220km on a tank - anyone else come across this?

yes it seems if i get gas before 160 miles ..my range says 140....but will stay at 140 for a longer time and will all average out when i get close to 160 170 miles........sometimes its starts at 140 sometimes starts at 160 plus

Before the flash mine would always be about 210-230km (140 miles) but now will never give a range above 140km (90 miles) although it will still do 210+km

Yes, counts down more slowly so gets to close to zero at the correct point

I would guess that it some sort of code behind - estimates the range from previous "use".
If "use" is endless sessions on dyno/tuning with *Woolich*, the range would probably be calculated next to nothing.

I see this "pattern" on my GSXS and my 2013 Focus.


If I drive my Focus 1.0 Ecoboost like old grandpa to church in 6th gear everywhere the range (full tank) is estimated to approx. 1100km.
Now in winter with lots of snow/ice/cold starts..etc.. the range drops to approx. 700km on full tank.
It adjusts to whatever driving "mode"/usage, which is quite obvious if you think about it.

2015 - GSX-S1000
2009 - B-King 1441

Were you adding fuel to the stock tune with a fuel tuner before the flash?

My driving style hasn't really changed as canbe seen from the fact that the actual range hasn't changed, and even if i drive very economically it wont give more than 140km. Its almost as though it thinks the tank is smaller since the woolwich flash.

The ECU will calculate the range from actual fuel usage. It als has some reference data you cannot change.
i bet you added a lot of fuel to the IAP Maps, especially in the lowest areas, to make the bike smooth.
the bike will then consume about 0,5l up to 1l more gas per 100km, but it will also confuse the ECUs range prediction algorithm.
solution: subtract fuel from the IAP map where possible without sacrifice throttle smoothness.
This requires many more test rides. if you make it, the bike will run smooth, and consume only 0,2l more fuel than stock, and the
range prediction will work almost like stock.
ECU tuning needs experience...
