I have an 08 scg with an Aug 07 build date. Using ECMSpy I was able to determine that my EEPROM version was BUEOD0CB 06-04-07. I found the most recent version of the flash online BUEYD0L4 03-20-08 and though it should be easy enough to flash the EEPROM to that. That's where things started to go bad. I backed up my version and then reflashed to the new version. Did a TPS reset and a AFV reset. The TPS did not reset and the bike would not start. It just made some clicking noises but did not even turn over. Ok, don't panic I thought. So I reflashed to the original version. I was able to reset the TPS, but... nothing. It just makes some clicking noises and does not turn over. Now I'm screwed. I can't figure out how to get the bike started. Everything in ECMSpy seems to work, I cleared all the codes, I checked all fuses and they are intact. No error codes are reported. I can fetch the EEPROM and burn to it without a problem, but no luck. Anybody have a clue what I could have done? Have I simultaneously fried my electrical system and voided my warranty? Any help would be appreciated here. | ||

How long was the bike sitting with the key on? Sounds like a week battery first. Take a volt meter and see what the battery reads, It will take a lot less power to run the computer then to start. | ||

Does the bike have to be on when using ECM spy? Is it possible that you drained the battery while doing the flashes? I'd check the battery and charge it if necessary. | ||

Tq_freak beat me to it  I really need to learn how to type with more than two fingers and two thumbs. | ||

Just to put that clear: "reflash" means putting a NEW PROGRAM into the ECM. This can NOT be done with ECMspy. What you can do with ECMspy is to put new DATA into the ECM - but is data has to comply with your program version: OD0CB needs OD0CB data, YD0L4 need YD0L4 data. To change from program version OC0CB to YD0L4 requires a reflash. So seemingly you are the first one who succeeded to fry his ECM. Who told you to put wrong data into the ECM? | ||

Nobody told me, I came up with that one myself. So I perhaps I can indeed lay claim to frying my ECM. Is there any way to check? It seems like all electricals are working and no error codes get kicked out. | ||

Ok, label me an idiot. I hooked the battery up to a jumper unit and it started right up. The flashes must have drained the battery. It has been sitting for a while. All that being said, let this serve as a warning to you all... DO NOT PUT YDOL4 data into an OD0CB ECM!!! | ||

Are you able to restore your saved data? I reckon you need a dealer to do the actual program reflash. Then (and I hope Gunter chimes in here) I believe after flashing it to YDOL4, you lose the ability to alter maps with ecmSpy since it works with OD0CB and not YDOL4. I'm not sure about that so I hope Gunter blesses us with his knowledge again, but it is what I've gathered in my little info quest going through the archives. My speculation is worthless though. Fact would be much nicer | ||

I was able to restore my original data. But as Gunter said, I technically didn't flash to YDOL4, I just the wrote the YDOL4 data into the ECM. It was definitely in there, cause it made things look all screwy on the overview screen of ECMSpy. I was able to restore to OC0CB without any issues (other than the ones listed above). From what I understand you do loose the ability to alter maps in ECMspy with YDOL4, however, it can be (pretty soon) be done with DDFI-III tuner software. | ||

Cool. So you're good to go Whew!  | ||

Actually, you CAN alter the EPROM data in the 08 & up. All the features of ECMSpy do NOT work however. This is not technically a re-flash though. But I've been able to alter values and restore them from saved files. None of this is my work, I'm just the guy with the bike. Just saying that some things can be done. | ||

I always take the headlight fuse out when I connect with ECMSpy or DirectLink, and I always make sure that the charger is connected to my laptop. Even if (maybe especially if) I think it is only going to be a quick one. Thepod, it way be worth taking the bike to a dealer so they can reload the data designated for your VIN. Just to be safe. If you have a good relationship with the dealer they may not charge you. It takes all of 5 minutes including getting the data from the net. | ||

Another BadWeb happy ending. Good deal! | ||

@Petebueller What data are you referring to? I have reloaded my original EEPROM. Is there something else that I am missing? | ||
| Petebueller |
Hi Thepod I may be being too conservative. It seems to me that if you load data from a different version, you could poke values into locations that are not backed up. When you restore your old map it may not be a complete restore. The download from the dealer should restore the ECM to spec. It could also upgrade it if that is what has been decided for your VIN. You may or may not what that. | ||
| Thepod |
Is there any effect to having a download from the dealer vs restoring from a backup performance wise or otherwise? It seems if I tell them that I have restored my ECM it invalidates my warranty anyway? | ||

if you load/re-load EEPROM I think you that data plus the map values... it is possible to only load maps. you and the dealer will do the same thing with the flash which can be good and bad. it could be bad cause your ECM has learned how you ride and that's what you're loading. the data from the dealer won't have this so it'll take time for the ECM to learn it all again. it might be good because there might be something in your map that got corrupted or stuck (this happened to me). using the dealer data may clear that. | ||

Is there any effect to having a download from the dealer vs restoring from a backup performance wise or otherwise? No, nothing that affects mixture or engine management. You should get the latest flash for the bike nevertheless. |
