ToadRide Need an OBD tool.

OregonMike I do the TPS on my TLR and GSX-R start of every season, and mid way through. Once I knew how to do it, takes maybe 30 min. Makes a difference in how they run.

Stromaholic Seems that the Service Bulletin has just been issued for Australia.....

blues hurler Well, I just got the recall notice that Suzuki is going to replace my ECU. Dealer says they only heard of this problem last week (right...). And my insurance just expired for the year. So I either get some insurance for a day and pray for good weather or wait till spring.

G-Dub I just checked Throttle Position Sensor adjustment in the service manual and it doesn't even mention adjusting by voltage, just by the dashed line in the display. Put the bike in what some call Dealer Mode using a jumper on the connector under the seat or using a switch that plugs in (a little spendy, but simple and no room for error, part # 09930-82720). Then read the "c 00" on the display. The dashed line should be in the middle...."-c 00". If the dash is in the upper or lower position then the TPS needs adjustment. You have to lift the tank and it's on the left side, the one nearest the seat. The secondary TPS is farther forward, you don't want to mess with that. To adjust it you need a T25 torx bit, I believe it has to be a security type with a hold in the center.

2mstone Thanks for the responses. I'll have to figure out how to do the TPS and try that. The when it quits it is when its cold and I pull in the clutch to stop or slow down....letting the bike warm up is what I"ve been trying to do, and will have to let it warm a few more minutes.. My neighbor lets his HD idle for a LONG time before blasting away...maybe I'll try the same thing.. LOL

Some have found on the GSXS that TPS mis-adjustment can be a cause of the "snatchy" throttle many experience. Apparently it is not easy to get it exactly adjusted - the spec voltage range is only a few hundreths of a volt and then it wants to move slightly as you're tightening down the locking bolt. Never looked at it on the Strom, but I assume it would be similar.

Probably doesn't hurt to do an occasional throttle body sync as well; I understand this can affect idle and low rpm running.

blues hurler My 2014 is cold-blooded as well. I don't bother letting it warm up, just blip the throttle a bit to keep it running when I get to the end of my driveway, and within a block, no more stalling, though it's a bit snatchy till it warms up a bit. I'm used to it now. I did tell the dealer about it while under warranty but I don't think they actually did anything. I paid to have the TPS adjusted one time and that did seem to help the bike run a bit better, but that's it. Just put a Ducati decal on the tank and then it will all be part of the "character" of the bike and no-one will bat an eye when it runs like crap when cold.

I have 55,000 miles on it, bought the bike new in June of '15, and on a recent trip to the east coast it started dying at low RPM when cold. Once I've gone a few miles she runs like a champ. Usually I can bump start her but yesterday she died on a corner .5 miles after starting her up....right in front of a big black SUV. Luckily my wife was driving the SUV and not angry with me at the time.

So does this sound like the ECU problem? Once again, it is only for the first couple of miles, no real puffing problem, runs great after warming up.
Obvioiusly I could be wrong, but I don't really think this is the ECU, as the problem with it shows up from almost day one. I assume when it died in the corner it was in gear and the clutch was engaged. Mine never died when driving, only when stopped. I assume the "puff" is the engine quitting briefly and then being instantly restarted by the wheel turning the engine. On the original ECU I had the engine die while idling several times. Have not had that problem with the new ECU but have had the "puff" a few times since when the engine was cold. Now I just let the engine warm up a couple minutes before driving away, or if I take off right away, I'll make sure to slip the clutch in the first few turns to keep the rpm up.

I would look for other problems, easiest first, like check battery terminal connections, main ground connections (did you have the recall work done?), maybe run a strong mix of Seafoam through a tank of fuel in case you're having some varnishing issues, spark plugs, etc...

I had some Suzuki factory engineers hook a recorder to my bike while I rode around to try and analyze any potential problems. They didn't find anything but did notice that when I started off, the RPM would drop below idle speed. They pointed out that this is more likely to cause a stall, so I've made a conscious effort since to always slip it a little more and keep the revs up when setting off from a stop.
