I follow all the instructions, I hope, but when I press program ECM with my sert software on my 2007 Fatboy
the program goes to 20% in the progress bar then starte"ECM access Denied".
Clues anyone?

Did you turn the switch on the handlebars to RUN?

And first thing you should do to make sure the SERT is communicating with the ECM is press "GET ECM INFO".......if this happens, then you can rule out the other stuff, like choosingthe right COM PORT, Switch on, cables hooked up correctly.....yada...yada.

Make sure you have a constant power supply to your laptop too(not just "chancing it" on battery power....plug the **** in!), any SNAFU during a flash could be a trip to the dealership on a trailer to have the ECM reconfig'd.[&:]

 

I got the ECM info so it looks like it did communicate that to the PC buts thats it.
Connection does not seem to be the problem and bike does run so I did not reprogram anything.
It is only when I try to program I get the access denied thing. Yes the run switch is set to on.
S@@T.

 

I've never tried to see what would happen if you try to flash it with the wrong map as I have enough on my plate besides explaining to my dealership I'm a dumbazz, but give the specs of your bike and the map you are trying to flash and let some in here give somemore input.

 

I/m trying to flash Map #67 off the H version disk. It is a 2007 Faboy with Arlen NEss Air Filter and SE mufflers.
Those are the only mods.

 

If the bike/SERT is communicating it seems like it would flash.....as I've flashed mine numerous times.


Try reloading the SERT software to rule out a possible corrupt file.

 

Shoot Shovelhead Bob a pm with your question. I'm sure he'll catch this post but he may not be on right now.

Does your message say, "requesting contol of J1850 serial data" and then say " unable to install bootloader"? I've seen this a few times and the issue is getting your computer to communicate properly with the ECM. Are you using a 9 pin connection or a USB adapter. If you are using an adapter it is probably the culprit. The cheaper ones will usually not be sufficient in data transfer rates. A USBG-232 USB adapter from USB Gear should solve your problem if everything else is configured correctly.

 

VERY GOOD POINT.[sm=smiley20.gif] The USB adapters have been known to reak havoc to your mind when trying to flash.

 

Yes it does say "requesting contol of J1850 serial data" right befor it denies me access.
