This has probably been covered a thousand times....but I have read threads for the past two weeks, bookmarked some even, but I still am a noob and I need some handholding!! details: 2003 XB9S, all stock except the 'white wire mod' and PCV's vented to atmosphere (all the hoses were missing along with the airbox, so just T'eed them and ran a single hose down) Bike sat for a few years, was missing some parts by the time I got it....I now have the bike running and rideable, but does not idle very steady, sometimes will idle fine but then dips low (~600rpm) and sometimes stalls, has a good bit of stumbling off idle/2500-3000 range and does a slight stumble/hesitation at a steady cruise in the 3500-4000 range. I used ECMspy to reset the TPS and reset AFV, did a half hour ride to include about a ten mile steady 3500RPM stretch....Bike seemed to have better throttle response, also pulled harder! BUT, towards the end of the ride, the idle stumble was back....stalled a couple times at stoplights. when it is idling ok, it's right at 1000RPM... I have new intake and exhaust gaskets on the way to eliminate the possibility they're leaking and causing the poor idle, off-idle and steady RPM stumble, and the occasional backfire in the airbox, and decel popping. the bike also has new NGK plugs and new wires installed (cause they were missing too, but am using the coil that was in the bucket of parts with it...) and a pretty clean looking air filter that came with the flea-bay airbox I bought for it. also all new fluids and filters. The fuel pump it had was in bad condition from sitting, very gunky sorta rusty and the screen crumbled when I removed it, so I bought and am using a used one off ebay, should I rebuild it with new autozone pump and screen just to eliminate that possibility too? Anyways, here comes where the steep learning curve is for me.... 1st, when I bought the ECM cable, I got a disc with ECMspy/tuning guide/driver/and some maps....How do I save the eeprom and map I have now, and how do I then burn a stock map back onto my ECM to eliminate the possibility it has some modified map already? When the bike is connected and communicating, there is still no option to load/save for maps or eeproms under the file button. Am I just missing something? I open ECMspy as administrator BTW 2nd, I need to know if I have to buy megalog viewer MS to run VE analyzation, or is there a free download of it somewhere? I don't mind paying, but if it's available why not? Again, sorry for all the noob questions....not only is this is my first XB, but the first time I've used a windows computer in about a decade.....I have a '96 S1 that runs great, but not nearly as nice to ride around in the handling/suspension/brakes dept. as this XB is.... | ||

If you have it comunicating with the bike, then you are well on your way. You should see the TPS value change when you roll the throttle. You need to go to the "View" menu and select "Professional". This will get you more detail and options of what you can do. Next, it's a good idea to pull the fuse for the headlight and perhaps hook up a trickle charger while working on it to keep from draining the battery. Then go to the "EEPROM" tab and click the "Fetch EEPROM" button. This will load the map from the bike into ECMspy. Once loaded, you can save it to your computer by clicking on the "File|Save EEPROM" menu item. You can load it back from the computer by clicking on the "File|Load EEPROM" menu item. You can burn it back to the bike by clicking on the "EEPROM" tab and clicking on the "Burn EEPROM" button. Hopefully that will get you over the hump on getting the data in and out. | ||

Thanks for posting! I meant to post up a little while ago that I was finally able to figure out switching to professional mode...now to get some logs tomorrow, do the analyzation and load the corrected map! | ||

I do think I noticed a slight change I rpm when doing the propane test around the intake.. | ||

You'll have to fix the intake seals before anything else is worth while then. I'm guessing it will solve all your idle problems right there. | ||

I hope so, and ill post up the results asap |
