Can U swap ECU 427 907 551 L for 427 907 551 ?...

my application is an 01 6 speed 427 907 551, donor ecu 427 907 551 L is as well. I can deal with the immobilizer issue, just wondering if that is the only hurdle.

I know you can convert a 551M to a 551K and back again....

But they both ended with a letter. I don't think I've ever seen a 551 with no letter.
