Their website is unclear, it lists 2 possible options. To be honest, I’ve gone as far as I can, will be looking at xHP Flash and DME unlock to run BM3.
Car has run a best of 11.20 @ 123.78mph with a 1.69 60ft. Data logging shows torque limiting from the gearbox, trans is shortshifting 2-3 gearshift.
Toretto Shifts and Baski can get these things into the mid 10’s without much effort, 9’s with exhaust mods and ethanol fuel mixtures.
Me, I’ll be happy with mid 10’s.

Ok, so when I bought it it looked the same as just now, I chose R, as I have a "G30", I believe F was the previous?
No idea how to attach a pic, but there is a simple drop down making it clear there is only one for the entire "G" chassis, with my car being a "G"
30 m550 and know the the f was the previous the logical choice was that section. That said, I'm a little worried now.
Was it difficult to flash?
