Recently bought an ECU off of eBay and had it mapped by Dynotronics for an '05 (following a bunch of mods, race exhaust, stacks air fliter...). The original one still works in the bike, but the remapped one does not. The fuel pump doesn't activate as it usually does when the key is turned on.
Is this because each ECU is paired with a specific key set? If so, can this be disabled/worked around?
The easy solution would be to send back both ECUs for comparison, but the shipping cost from here is triple the price of the ECU (#%^)...last option only.

Any ideas?

If you just want to get your fuel pump working....Just get a 12volt relay and run power to fuel pump using one of ignition wires as a on and off switch...

is this a Euro bike? If so the immobilizer on the euro models is probably not configured to your key.

^^^ Says in the service manual

"If the code does not match, ignition system, injectors, sub-throttle valve actuator and exhaust butterfly valve actuator will not operate and the engine will not start"

Also, the US models do not even have the immobilizer code in the actual ECU that is why EURO and USA models have different ECU numbers because they are programmed differently.

If this is the case "thegreencobra42" I would suggest selling it to someone in the US or you will have to swap out some of your electrical system to make it work on your bike, this could be possibly just the ignition set or it could be a harness, I would have to check part numbers :-/

If you have a EU bike and a US ECU you can disable the immo BUT you need to activate the US antitheft system,which is a a +12V feed to an ECU pin via a resistor ( I don't remember by heart the Ω resistance) but I can look it up...

Then you need to unplug the immobilizer plug...

This way I think it will probably start... :dontknow:

Does the serial number plate provide the info as to the origins of this bike (EU or US)? Not sure where she was born...

The point is to identify if it has an immobilizer system or not...

If it has an immo then you have to unplug it from the main ignition switch and put a resistor on a pin that is currently being unused.

The thing you can't plug'n'play both ECU's,you must wire the bike for the one or the other...

Me not being a master at electronics, if I unplug the immob system and the rest that you said, is this reversible if I need to revert back to old config?
