Termanology only, rom,map.hex.ptm ,reflash, ROM image
I understand that Roms have specific coding to match the ECU date,type, vehicle type, transmission , blah blah, and maps are variations of that original Rom image but its just a term, Im not being specific, I call em Roms, maps, crap flashes, rocket flashes, you get the picture.

e.g your comment on fuel trims a little up the post, its closed loop fuel targets, trims are automatic % of fuel pulled or added by the ECU to reach that target, no biggie, just termanology and I knew what you ment.

Agreed on the off the shelf jobs, but these can be good starting points for improvement
