Hi guys,

I'm wanting to download beeme code for my 16 plate 435d. Do I need to back up normal ECU incase I mess up coding/code something wrong or the car throws a wobble?

Also i have the tourqe pro bloothooth adapter small blue one was about £5 I'll attach a picture will this be fine to use will it be compatable or do I need to order a specific one?

And will my stage 1 map be safe.

Cheers.
