Very nice that you started to work with b48 because piggy-back is the only way to tune that engine. B48 dme is not tuneable (new ecu is closed for tuning) but the engine is good. That new ecu can be tuned for some options when it is all-new: vmax & ***-off. After 10 working hours the ecu is closed for any changes and there is no any tool in the world to crack it

So we will wait for warm Spring weather and will buy one BMS piggy-back for our shop car Of course we made ***-off and increased vmax limiter while it was new.
