Is it possible to add a sport's button mode to a bravo t-jet?
As I had added a Cruise control mode to my T-jet I wonder if I could do the same for the sport mode option.

Interesting... but i would say ... not.. at least not easily/cheap.

I think it is probably only a software thing. So .. as long as you have a 150 sport car's ECU then.. it might work.
The other solution.. get somebody with a 150 sport car, read the ecu, then write on to your ECU.. . you will need a lot of extra work to make sure it actually functions together with your body computer...etc
