Fuel map issue?

I used BHP but I purchased the ECU Flasher.
For me, although the 1250 is much better it was the lower speed fuelling that I still found jerky and a slight flat spot around the 4-5k.

A big thumbs up from me. :thumb2
As has been reported before on here. You purchase the flasher, download software on to a laptop, plug the flasher into the ECU to take a reading of that map, email it to BHP, they assess and match it to their own map of an R1250GS, sent two maps back to me, one for earlier valve opening and one for constant open valve.

The flasher can store ten maps so I have three stored and can put the original map back on at any time.
Takes about 10 mins to upload a map onto the bike.

If you sell the bike, you can have the flasher reset, then purchase a new map for your bike (providing it's available) at a reduced rate.

Made a massive difference to me. When I enquired they told me that the difference between having your bike on the dyno and the emailed map was not a big difference. They are so confident in the emailed map that they told me you can have it tested against the dyno if you so wanted.

They also offer this for the 1200.

if the dealer updates the ECU, do you just reflash it?
 
Yes you have that option.

My BMW dealer confirmed they only ever reset the ECU if there's a problem, they never update as a matter of course.
But yes, as Malcopopolo has stated, you just flash the map back on to the ECU.
 
Can you say for sure without putting them on an independent dyno before and after?

Interesting that there's no massive gain claims and that they show the afr's post-remap, something you don't see from the above mentioned organisation.

The guy come across as genuine to me.

I have to disagree. I’ve had several bikes at the aforementioned premises and I have printouts with post remap AFR readings.

why doesn't Geoff ever measure them, in his magic remaps.

ECU tuning is all about adding/subtracting fuel compared to the OEM fueling, and to a lesser degree, modify the ignition timing.

Any time the fueling is modified, it will be revealed by a change in the AFR. Thus, the AFR is the true indicator to how the fueling has been modified.

If someone is sitting on Dyno readout (from the company mentioned above) that shows the additional information of AFR and throttle position (to ensure the compared readings where done with the same powersetting,, now is the time to publish, and rubb it in :beerjug:

Unicorns :D
For the record my 1200GS had:
Magic Map - slight improvement for a few rides - suspect something was reset as over time surging returned.
I then fitted 2 xafied installed and the fueling was sublime - sold them as hassle at insurance declaration time
I then went BHPUK route - same results as axfied - fueling is sublime.

These were done with WOT
The nice smooth one is euro 3 and that is a fair representation of how the bike felt before and after.
The roller coaster is euro 4. I didn't notice any difference between before and after, this where, perhaps, things were not as they should be.
I have now got the AF-XIED on the E4 bike. This has smoothed the low down running and has helped a bit for the dip in the middle. I run setting no.8.
I don't think that the E4 bikes will ever fuel properly, I don't know what BMW thought they were doing.
Insurance was not a problem for Bikesure when I told them it was a bit like a Power Commander but less fancy.
 
Here they are.

so he managed to gain you almosst 20bhp,,, in 40 mins ???????????????? or have i mis understood ??
 
Thank you to @CPJS for sharing :D :okay

I don't want to rain on anyone's parade, but the Dyno curves that the 'Magician' provides puzzels me.

There are lots of dyno runs published on net. The 1200 LC consistenly deliver between 115 and 120 HP, and at full power, the AFR is in the 13.5 +/- range.

The exeption seems to be the 'lucky' ones, that for some weird reason happen to own a bike that under-performs substansially when compared to the crowd. How this under performance may occure is a mystery, as the ECU is digital and the fueling is guided by the O2 sensor.
True, at full power the fueling is liberated from O2 sensor restraints. However, the sensor is still there, and it reports back and provide feedback to the adaptive map, which is always a part of the equation in the fueling.

And also, the end result seems to be on par with everyone else's dynoruns when testing their bike prior to a tuning...

I leave it up to anyone to draw their own conclusion :beerjug:
