I've been having intermittent stalling problems and some surging in my '03 Strom. Had the fuel pump replaced, no improvement. It's been suggested I get a new ECU...$1600!!
So some questions.
Is there a source anyone knows of I can get a less expensive unit?
Do I need to have a mechanic put it in or try it myself...not mechanically inclined.
Stalling is generally too low of idle "should be around 1200" and the surging issues can be fixed with a Power Commander 5.....MUCH cheaper than an ECM.
Fleebay has a half-dozen ECMs for that bike from $200-250. For the L2 there is a Service Bulletin to replace (at NO cost to the customer) if the bike is experiencing the problems you are having. My 2012 is in the shop at this moment getting that done. Many folks that are installing Power Commanders and remapping to enrich the low and mid-range to resolve the poor performance between 2000 and 3500 RPMs. If the ECM does not fix my stumbling problems, I will install the PC. Good luck, Bud...
About $75 for a new TPS vs $$$$$ for a new ECU which it probably doesn't need. You can even change it yourself if you are just slightly mechanically inclined.
The Throttle Position Sensor is basically a rheostat. While it might test ok, it tends to act up when it gets warm. Since it gets a LOT of wear in a certain area, that area gets dirty and the contacts don't work like they should.
We have seen this over the years. Yes, it is hard to believe and your dealer may not agree. But the collective experience on this forum knows exactly what the TPS can do to make the bike stall and not run properly in the lower rpms and light throttle settings.
replaced tps. on start-up rpm at 1000. once warm up to 1300.
Still stalls after a couple of blocks at stop light. once warm ran ok but need to ride it a little more.
Continue the saga.
With less snow got the bike into the shop. Increased cold idle and cleaned injectors. No more stalling as of yet. Now I get a breakdown of power and some backfire between 3600 and 4k rpm if throttled up slowly. Hit it hard not a problem just if gradually increased throttle. Any thoughts. All computer readings are fine.

now your Vee is running the way suzuki intended, albeit not perfectly. all Vees do this in that powerband. the fix is a yosh box adustment or a power commander.
I will look at a PCFC when I can find a good supplier and good price. Looking at a works clutch cage as well.
Been busy with new bike fjr getting it ready for summer so Vstrom has been in the garage sitting.
