Alright so i have bought an 06 lightning xb12ss. it ran fine for a few days and then had some low idle issues. I honestly know nothing about bikes so i ended up here looking at some stuff. eventually figured out it needed a tps reset and a breather reroute. I had the harley shop do the reset and i did the breather on my own which was easy thanks to everybody here. I live in alaska and the harley shop here is not known for being very good. I didn't enjoy my experience with them as well. They told me the reset didnt do anything and my bike was choking itself out because the exhaust valve was bad. They priced me for like 5 hours of labor at about 115 an hour and $500 dollars for a new muffler some screws and an actuator cable. I said no because i remembered reading up on wiring it shut and programming the ecm. Here is where i messed up. I took care of the valve and the bike ran a little better now it wouldnt die and i could keep it running with a little touch of the throttle. The breather really helped. But it was running rich and with a much higher idle until about 30 minutes of riding and then i had to feather the throttle at stops to keep it running. I had no luck getting ecm spy to work so i used tuner pro. I do not think i did the firmware correctly or something because i didnt want to pay for anything. I ended up downloading the ecm info from the bike. i found directions that sounded so simple for unchecking a box which would delete the exhaust valve but on my tunerpro rt it wasnt there. I decided to change something just to see if it was working. when i uploaded it to the bike it tried to run died and now it wont start at all. What i believe i did was upload the emulator without firmware or something. I tried to upload the backup save to correct what i have done and its still screwed. did i put stuff on my ecm the ecm cannot interpret? when i turn the key the fuel pump doesnt even prime or anything.
 
reverse course and start from square one. did you save your EEPROM (meaning the entire ecm contents) and copy it to a dedicated file.....where you can retrieve it....prior to screwing with your ecm? if so just retrieve it and reinstall onto your ecm. then do the simple things like checking your breather work...ensure your plugs are good and fuel is fresh....and plug wires in good shape. and you say you wired "shut" the muffler interactive valve???[confused]
 
I wired it open. When i downloaded the eeprom i did save it twice one named backup. I tried to put it back on. I think the problem is what i put onto the ecm it cannot read.
 
ajus - somebody's got to have a stock map for an 06 they can send/host for you help ensure you're returning to an unaltered stock map. do you happen to know your firmware version?

I'm an 08 so no good to you, sorry.......

So are you getting an error message? If so, what is the message?

Also, double-check that your COM port number hasn't changed. It can/will change if you move the USB cable into a different port (at least for Windows). Tunerpro doesn't always pick up on the change.
 
That's rough! Sorry to hear, but get yourself the ECMSpy cable kit and disk on eBay, then follow this:

Fuel Maps

From there, you can disable the stock can valve or get yourself an aftermarket setup.

P.S. I have an '06 12S and can send you stock maps or factory race maps, if need be.
 
sorry i was away for work. Let me grab the laptop head out into my little shack and see what i come up with.
 
okay when i plug in the bike and turn it on i press initiate emulation and at the bottom left of tuner pro rt where hardware not found normal is Bueib310 pops up. This is the firmware correct? and i have tried to upload settings again and got nothing. There appears to be no error messages. when i download the unaltered settings to the bike it tells me download successful. also i have been using the same com port just incase something like that happened. i was very careful and also checked to see if it did.
 
If it identifies the ECM as BUEIB310, it can at least send/receive data to the ECM. Yes, BUEIB is valid for a 2006 Lightning. Will your bike still not start?

Something you can try is download your eeprom again, save it as a binary, and compare it with a stock 2006 XB12 eeprom image from Buelmods.com Tunerpro has a difference tool that makes it easier. There will be some expected differences, but it will tell you what else changed. You will have to convert it from a text file (from buellmods) to binary first before comparing in Tunerpro.

If none of that makes sense, I can compare your current eeprom for you - just need to upload it somewhere.

what do you mean what have i done? the only thing i have done is changed one setting and uploaded it. then the bike would not run for more than 2 seconds. so i uploaded the orriginal settings and now the bike will not fire up at all. the fuel pump does not even prime when i turn key.
 
well ill be damned it was blown. replaced it but the bike still does not start im going to check for fouled out plugs next
 
Perhaps the ECM is not the issue and coincidentally something else has malfunctioned. This would seem so, provided the 'original' firmware has in fact been restored and the bike still refuses to run. Which sounds like it's the case. Good idea to just back off it a day or two, go do something else, then tackle it once again with a clear head.
