Any changed computer will have to be setup with the injectors. The problem with these early ficht injectors is that they are not all calibrated identically when made at the factory. That calibration determines the unique spray capabilites of that injector. So, when you install them, you have to tell the computer just which injector is going in which position so that it compensates for each of them-so that all of them spray identically when running. That's why you need to calibration software. Contact your local Evinrude dealer-they sell the software you need. It will be difficult to find a spare computer. They are always replaced on a direct exchange basis only. Same for repairing them. You may find one used off a scrapped engine.
Thanks for the explanation! I did order the diagnostic cable and software. Here's what I'm hoping I can do. When I get the cable and software there must be a way to record / save all the files on my current EMM right? Then when I get a new / used EMM couldn't I then copy over all the files on it, including of course the injector coefficients, there by making myself a replacement EMM? Would that work?
I would also like to have one spare injector. My engine is a 2001. It looks like by 2002 the injectors started coming with that bar code which can be used to get the coefficients correct? Is there really a physicle difference between a 2001 FICHT Injector and 2002 FICHT injector? If not it would seem the best route would be to look to find a good used 2002 injector of which I can get the codes. In the event I have an injector go bad I can replace it with my spare and use the diagnostic cable and software to write the new injector codes to the EMM.
Does this all seem plausible?
My main rational to doing all this is two fold. A I don't want to always wonder if I'm gonna get stranded thus taking the fun out of boating. And B I do a lot of long distance boating on lake Huron in Michigan as well in Ontario all the way into Georgian bay where my family has a cottage. There are places I would really be hard pressed to get help. Not to mention if I did I would probably need to take on a second mortgage just to get it running again :[
Any info would be greatly appreciated. Thanks!
