Question on ECM swap

[xfactor]

My S10 has a 1228062 ECM
I picked up a 1227747 ECM
Will it work if I put the original 1228062 memcal and eeprom in the 1227747 or will it require a different bin file?

No, that will not work. You need a bin file for a '7747.

Thanks - that's what I was thinking after it ran like crap.

It has a built 3.4L in it so needs a new bin file anyway.
