I was told today by Chandler HD that they cannot and will not flash my bike to have the 07 airbox lid work on it. That was my last straw with them..... Guess I need to find another dealer. Maybe Arrowhead? | ||
| Jmhinkle |
That is absolutely ridiculous when it takes all of 5 minutes to do. They truly don't deserve to be a Buell dealer. I bet if you take a Road King in there and it needed a custom fuel map they would be all over it. | ||
| Stevenknapp |
I removed my ECU, sent it to DaveS, and it arrived back with the 07 map it in. $30-40 total I think. | ||
| Birdmanrh |
Crap, never thought of that. I could next day air it and still be cheaper! Probably have less down time with the bike as well. Thanks for the idea. At least I have found a shop (Kawasaki) locally that can do the regular service. | ||

StevenKnapp, How's the bike run with the re-flash and 07 box? I put the 07 airbox on my bike and while it seems to make slightly more power it sucks the gas like no tomorrow. I'm contemplating whether to get the re-flash or go back to the old airbox. | ||
| Daves |
Yep, we can do them up for you. No problem. | ||

Appleton Buell (DaveS) reflashed mine. The ECM was at Dave's dealer less than 8 hours. What service!!!! The TPS will (might?) need to be reset, so factor that in too, if you can't do it for free. (Message edited by teeps on December 13, 2006) | ||
| Daves |
Teeps, are you sure the TPS needs reset? I would think it would hold the setting but maybe not? | ||
| Teeps |
Daves, you raise a valid point. I am not sure. I didn't try starting the engine with the reflashed ECM prior to zeroing the TPS. | ||
| Steveford |
As far as I know, you can do the '07 reflash without resetting the TPS and there's a version for the 9 and one for the 12. Use any 2007 VIN on Digital Tech to get the download. According to tech services, the reflash is a minor difference from the '06 calibration. In other words, you're probably not going to notice the difference. For the race ECM I believe that it's don't bother, just pop on the airbox lid. (Message edited by SteveFord on December 13, 2006) | ||

I've been traveling and it's been nasty weather. The ECU is back in the bike, but I've not had a chance to ride it.  I thought I saw in another thread where MPG was returned to normal w/ the new flash. Without the bike does drink more fuel. | ||
| Teeps |
Stevenknapp, Does your bike start and run? | ||

| Jmhinkle |
Actually that was me. Before the reflash, my MPG drop significantly from '06 box to '07 box with K&N. The flash actually improved my MPG to better than '06 results. I think Electraglide '97 also saw a drop in MPG and fouled a plug too. I think the ECM tries to overcompensate because the '07 box flows more air than the '06 map is set up for. My bike ran exactly the same pre and post flash except for the improved MPG post flash. I do have a small cold start issue, but nothing so bad I've worried about it yet or looked into fixing. | ||

I have 07 air box and the 06 flash. The very first ride I took with the 07 box I made sure to let the bike warm up for several minutes and got it into "learn" mode on the road and kept it there for 15 or so miles. My MPG is the same as its always been. (Message edited by ChrisB on December 14, 2006) | ||
| Stevenknapp |
My bike does start and run. Installed the ECU, zeroed the TPS, set the idle to 5.4deg, and it fired right up. I didn't get much past that. | ||
| Teeps |
Stevenknapp, I did the same as you. Daves' point was TPS reset, is probably not necessary. | ||
| Pso |
I did the same as Chrisb. It has run fine and even better down low around 2to2500 rpm. I figure if it ain't broken there is no sense in taking it apart to find out why not. | ||
| Bosh |
?? How do you get your ECM into "learn mode"? My bike with the 07 airbox is getting very poor fuel economy since I put it on. I didn't go through any learn mode thing except a wheelie down the street. That hOOOOOnnking sound coming from the air box is entertaining but I haven't been doing enough of it to explain the <MPG.;} | ||
| Chrisb |
This is a down and dirty of learn mode. If I am not exactly right...Well I'll appreciate you correcting me. Learn mode occurs when the following happens #1. engine up to operating temp. #2. rpm is above 3k #3. speed is between 40-60 mph | ||

Treadmarks said; For the race ECM I believe that it's don't bother, just pop on the airbox lid. It worked for me! Does that mean, with the Race ECM You don't need the re-flash and the mileage should still be good? If that is correct; do you need to ride it in learn mode for a certain distance? Or will the race ECM just adapt to the additional air flow?} | ||

Right after the install, it had a low rpm surge, and an occasional sneeze off idle. After about a week the surge went away so I guess it did learn some, but it still had an occasional sneeze. While swapping to iridum plugs I found a chaffed front plug wire and tried to repair it but the sneeze continued. I installed the 8.5 magnecor wires and relocated my harness under the airbox to eliminate the rubbing. The bike has never ran better. Better idle, no surge, awesome sound from the spec ops can, and 50+ mpg as a daily driver. The more I ride this bike, the more I love it.  | ||

My dealer stated they couldn't reflash...or that they have never reflashed... I had to persuade them to ask Buell. I am waiting a call back, and if not, I'm sure I'll send it on over to Daves for the reflash. Putting my bike into learn mode, didn't do anything for my 07 airbox on a stock 06 (stock can, stock air filter, stock ecm). I am now getting 42 mpg, down from 55~60mpg. I want my mileage back. | ||
| Teeps |
Michael1, By the time the dealer gets back to you, you could have sent the ECM to Daves, got it flashed and had it back! | ||
| Michael1 |
Yeah...but I am still riding it here in the chilly midwest (Cleveland, OH area). And I don't want to take the bike out of commission for the three days or so. I'll wait to send it to DaveS this winter. But I'm giving my dealer the benefit of the doubt right now... | ||

Michael1, Don't forget about winter gas season. While your MPG change is even greater than what I saw back in the fall when I did the switch, you also have to figure in the oxygenated gasoline that almost all major cities require in the winter. While it burns cleaner, it also fools your O2 sensor into a lean condition and causes it to run richer. I still question if this is truly better for the atmosphere or merely a business deal between the Gas companies and the feds. Nevertheless, you shouldn't see that much of a change from the gas alone. | ||

Jmhinkle Posted on Sunday, December 17, 2006 <snip> the oxygenated gasoline that almost all major cities require in the winter. While it burns cleaner, it also fools your O2 sensor into a lean condition and causes it to run richer. Actually our bikes will not run richer, per se, when using O2 enriched fuel. But they will use more fuel. Here's why: There is less energy in a gram of oxygenated fuel, therefore the closed loop system will add fuel (grams per mile) to compensate. This does not translate to a rich running condition on a closed loop system. But since there is less bang in a gram of O2 enriched fuel it translates to more fuel (grams per mile) to do the same amount of work.. Here is a link that goes into it in more detail. http://www.chevron.com/products/PRODSERV/FUELS/bulletin/oxy-fuel/enrgycon.shtml (Message edited by teeps on December 17, 2006) | ||

Sorry, poor choice of terminology on my part. Didn't mean richer as in 13.5:1, but as in more gas dumped in per cycle because of the false lean condition. It is a stupid practice by the government. The idea is that with more oxygenates in the gas that the combustion will be more complete causing less carbon monoxide. In reality, mother nature takes care of that by making the air colder in the winter which means it is more dense or has more "oxygenates" in it all ready. The gas companies just created a lean condition to your O2 sensor because now there is way too much oxygen left over after the burn which means the Fuel Injection has to dump even more fuel in to try to get back to 14.7:1. If the theory was used properly, instead of being used to stuff money into Hugo Chavez' bright red pocket, we should run oxygenated gas in the summer because the hot air is less dense and would you would not see as much of a drop in MPG. Thankfully, I live in a city that does not commit to smog checks and oxygenated gas so I can still get the good stuff at the right pumps. | ||

I put mine one today. WHEEEEEEEEEEEEE! It seems to open it up all across the powerband. It used to have acceleration and then a "catch" around 4,000 where it felt like it came alive. Now it does it from 1500+. I can't tell, but it seems to have changed the exhaust note as well. I may just be hearing intake "honk", but it sounds different. |
