MEFI 2

[ABMOTORMAN]

I'm currently trying to tune a boat that has MEFI 2 computers. (2 engines) I've made a dozen changes to fuel tables and now hit a wall. Now when i make a change to the large portion of the table something must be happening to the file. The computer does not fire the fuel pump at the end of the upload and the engine will no longer start. (No fuel pump) I put the original unmodified tune one back in at everything is ok.

Is there a limit to amount of changes to a file? The only difference i see when I export to text is check sum other than the fuel table changes made.

Using mefi210 XDF file i received from mefiburn. Tuning changes in tunerpro.

Any suggestions appreciated!

No, there's no limit to the number of changes. What do you see after you make your changes to the file, save the file to disk (file->save as), then open the original as a compare bin and compare the changes (Ctrl + T)? Do you see the expected differences?
