Here are some ECU swap information from Germany, which is not a recall but it's being exchanged on warranty. So far 89 members got it replaced as of 3/12/16.  http://www.v-stromforum.de/viewtopic.php?f=3&t=43607&start=360

The website of Reinhard also provides a lot of information about his power loss. He says his dyno results started Suzuki's ECU investigation and that Suzuki informed officially all dealers on August 4th 2015 about the ECU problem. Affected are 3 out of 10 early DL1000A L4 (and I believe L5). Culprit is the ECU J00 and J01, which were replaced with J02

ECU J01 got rid of the power drop in 2nd gear and the 3rd gear had more torque in lower RPM. No more stalling.

ECU J02 killed the violent vibration in 2nd gear at low RPMs still present with J01. It felt like the bike was trying to shake off its front end when driving in 2nd below 1500 RPM (about 25km/h). Now even at 1200RPM in 2nd the engine runs smooth.

Best rider's feedback so far after ECU swap:

- Bike sometimes dies after cold start.
Didn't happen anymore! Idle speed is a tap higher!

- Occasionally misfire.
Not anymore!

- Below 50km/h had to shift into 3rd gear because engine wouldn't run smooth and would start to jerk.
Now even in 5th gear and 50km/h smooth without jerking! Also the acceleration from 50km/h in 5th gear is without jerking!

- With traction control setting either in 1 or 2, the engine would 'have to climb out of the basement' when accelerating  in 2nd or 3rd gear. When accelerating out of a corner or when overtaking power loss was felt. Had to close throttle and slowly increase speed to control the weird loss of power.
Now merciless acceleration and the traction control light is blinking!


ECU repair time:
Dealers with no knowledge try to put of customers saying the swap would take an entire day. However it is being reported that the swap takes about 15min.
- short test drive
- seat off
- disconnect battery
- swap ECU
- connect battery
- program both ignition keys
- seat back on
- reset clock
- test drive

I live in Portugal.
My ECU was J00 and was swapped by J02.
I believe and can confirm a lot of mentioned in previous post, stating German experiences...
BUT...
talking about 1200 or 1500 rpm vibrations ???
At those rpm my bike would disintegrate, I guess... C'mon, it's V-twin!!

Had mine done last October.
Can agree with points above...feels like a completely new bike now

Sumo, Good post and useful info. My DL in at the two wheeled centre Mansfiled Woodhouse for the wiring recall, before I go early April I will check the ECU Number. Is the advice if it is J00, J01 get rid for a J02 regardless ?

Thanks
