Second-hand ECU replacement...
« on: April 19, 2021, 18:59:35 »
Hello blokes,

After a few issues with my 2007 Vstrom DL1000, which culminated in a new flywheel, I'm still getting some hesitation issues between 3,500-4,000RPM with the odd misfire.

I can accelerate through the problem zone, but would love to remedy it for a smoother ride.

TPS has been adjusted (including testing a new one).

Any thoughts on trying a new (second-hand) ECU? If so, does anybody have a 2007 ECU they might be willing to sell?

Thanks in advance :)

Joel

Another ECU won't cure your problem, you have a lean spot at the RPM you describe.

Obviously check that everything is in place as it should be, no air leaks, air filter is good, all throttle body pipes are connected.

This is a common issue with that era of Vstrom 1000, some suffer from it and some don't.

When I owned my K6 1000, I cured the issue with a power commander and a custom map developed on a Dyno.

Others will chime in with their experiences and cures but in my opinion, although the most expensive, a Power commander will achieve the best results.
Chief trouble maker 🙂

As Kwackboy says there is a lean spot at these revs. I occasionally get some hesitancy too, when I'm holding a steady speed or roll off the throttle and back on. It got better after changing the air filter as the old one was quite bad. It still catches me out but much less now.

Have you got a TRE fitted?

Like everyone else I fitted a power commando with dyno set up to my K6

Do you have  a nearby Suzuki dealer with a "Yoshi Box". I had my K3 adjusted with one and it solved that issue quickly & cheaply

Thanks all - will contact my local dealer for a quote and continue investigating power commanders, which seem like they might provide more flexibility moving forwards
