Launch Edition - Different ECU Programming?

[angrytoddler]

Just curious - I know it isnt advertised - But I have seen two people comment on the Launch Editions power curve or programming showing a little different than non LE?

But no on else seems to mention this and I have not seen it anywhere on this board. I do not see how this could be the case - but was curious. One mention was just in a car listing where an owner commented that the LE has a different mapping. The second mention was a Youtube where when tuning they noticed the programming on one Supra was different than another one.

Anyone have any thoughts? How cool would it be if the LE had a hidden easter egg for performance?

Ok - now - go ahead and make fun of me for my crazy thoughts - lol.

difference is most of the cars after the LE and a few of the early build non LE ECUs received a dealer patch that locked the ECU from being flashed via the OBD2. Whereas LEs could be. This makes no nevermind now as we can flash all models with MHD now.

There's the locked ECU thing and a few tuners mentioned a slightly different power curve (BMW may have tweaked the map slightly or it may just be a variance between vehicles).

Yeah I also saw a YouTuber mention there is additional lock after LEs and different map.

Pretty much same base calibration. Just some code changed to block the original exploit for OBD2 flashing. But we cracked it already on MHD. So no worries.
