I haven't downloaded the new spreadsheet yet but when I tested it years ago I didn't notice a major difference but didn't test too much either as I didn't notice that much change.... sorry I should have tested more.

So not sure how handy you are with editing XDF's but in the factory $11B the spark stuff at 8049 lines up exactly with 7049 so assuming the fuel/VE will be the same offset.

Another quick look it lines up well with kalmaker so depending on what modifications it has had it may not be easy to copy changes across to $11p

Ok so after a quick look it the factory BMZA1754 data at address 6000 lines up with the data at address 5000 on your file so I suspect it's a custom code of some what.

The only problem with that is the file on the memcal doesn't line up with BFFK even though that is what is on the controller sticker, does it look like the memcal sticker has been lifted & does that have the BFFK id on it too?

if it's factory stock memcal it shoulg be FM27C512 from memory

So did you read it off the memcal yourself it's a bit weird the data doesn't start till address 5000

maybe attach the file & then it can be identified if it is actually a BFFK file

Did you use the memcal ID tool, it identifies as $11A file so need to use that xdf.

Sorry a bit late but hope ALL the peeps here had a great day & bring on a fresh start in 2025!
