Hello all, 

 

I own a 2.0 TDI with 140 bhp configuration. I read somewhere that a person has swapped an ecu from Golf GTD which has 170 HP configuration to his 140 hp engine for extra power gains. It’s basically like you are tuning your car but by replacing the stock ECU with the stock ECU of a higher power configuration of 2.0 Tdis (Passat/Q3/Vrs tdi/Golf) . 
 

Please can someone tell me how easy or difficult this is ? and what are things to take care off 

 

Thanks

I read somewhere that Santa Claus is real!

While technically it would work as a BKD can be mapped to 170 safely it won't work as the checksum will be wrong along with a whole load of other issues with immo and accessories, better to get the OE ECU remapped.
