How do I know which transmission flash I have?

theslowe90 · 03-21-2020, 04:15 PM

Hi all, I owned my E90 335i N55 about a year now. I am pretty sure it came with a transmission flash when I bought it because it shows D1, D2, D3, D4, D5, and D6 in drive (as well in sports and manual but with different letters). I am thinking about going MHD stage 1+ but it asks for the transmission type and flash associated with it.... How do I figure out which flash the car has since both xHP and Alpina flash display the same thing on the dash?

Ask the previous owner. Or just flash the XHP and call it a day. Tbh if your running a stage 1 flash dont even worry about it click whichever one, the care doesnt make the power to make a difference. If your running 400+tq then i'd say flash with the XHP and dont look back.

Thanks for the reply. So should I just continue with the standard AT flash? If I do proceed with the standard AT flash, will it erase the current transmission flash I have on the car?
