99 Ficht 175 unreadable ECU info to Swap

[SPIDERMONKEY]

I have a 99/00 Ficht 175 and the ECU has issues (code 15, not fixable). It was purchased in not running condition for a song. So I found the same part number ECU of fleabay. I hooked it up just to see if it would run before going any further with it. It starts and runs fine...little stumbly on initial throttle but revs up. I know that the injector coefficients on the swapped ECU are not correct as they are for the injectors from the powerhead it came from and they have to be matched. I wont be running it like this as here is where my question comes into play. I managed to read the old ECU once and get a printout of the coefficients and serial numbers for each cylinder but now I can no longer read it as it has a communication error.
Using the E-Diag sofware can I simply perform a "injector replacement" on the injectors and use the information from my initial read of the original ECU or is there other information that is needed to transfer over also? I can set the parameters for timing, idle, etc the same. I just worried there is other data that needs to transfer so that I cant manually change over. I am wondering if there is fuel tables similar to an auto computer or if the coefficients are the only data.
I do know that the engine info wont match (serial number, model#, etc) but is that an issue from an operational point of view?

The ideal way would obviously be to copy over the one ECU to the other, but since I cant read the original anymore thats not an option.

Looks like I never finished this post off....3 yrs later..

I ended up fixing the original ECU and being able to read the ECU. I saved the info and was able to make the other a spare for backup reasons.
