is the 2.7ta tsfi motor? what does tsfi stand for?

 

I have NO CLUE what TSFI means, where did you see this?

Or, do you mean FSI or T-FSI, in that case, NO, FSI is direct injection, where the injector is fired inside of the cylinder head, & NOT in the intake manifold like most cars out there.

 

i was doing some research on chipping my 2.7t with the revo software. revo offers serial ports that plug into the obd port to change settings. some of the serial ports will only work on these types of motors. i figured someone over here might know which would be the est serial port for me. thanks for the quick reposnse.

 

this link may be help with what i asking

I believe Revo has another unit for the 2.7t, & yea the ones in the link are for the new FSI motors.

You can also change REVO settings with Lemi tweaks, it's a software program, that you can run through a Vag-com type cable.

The short answer is Revo makes a program for your car, & has both a software & hardware tweaking.
