I have a BMW OPS and am looking to re-code my car too. I want to update the CCC so it includes sat nav and include a Dension 500 gateway.
I think I have everything but now that I need to update the car's control modules. My only concern is the power supply. I need to source one or go buy one.
At the moment I can get one which is a bench DC power supply. It can supply a regulated 13.8V up to 25A. My question is will this be enough or do I need more amps??
Also, what is the best way to connect this to the car when programming??
Thanks a million in advance,
