What Do I Need To Flash Tune?

[AusFreak]

Hello,

I have a 1991 (Euro) 325i and I would like to be able to put some larger injectors in but to do that I need to flash the chip. Would anyone have any idea on where to start with this? I believe its an OBD1 ECU

Thanks

Chip burner, some extra blank chips, and some extensive knowledge and definitions of the particular data you are working with.

Which chip burner would you recommend?

I use a GQ 4x4 chip burner, but there are so many other types, cheaper and more expensive. I chose this one just because it allows adapters for modern chips as well.
