Hello all,
I have seen a few for sale on here, but i am still not sure what they are used for.
I know it is a piggy back ecu. But as i am not that tech minded i dont know what it does.
Could someone please explain to me what it is used for and what are it's functions. Someone said to me that it helps control the fuel when going na-t, but are there any functions/uses for a tt engine?
If so what are they? and does it help with controlling the boost? (ie incresing it) and does it help with fuel cut (same as fcd) when going bpu?
There are probably simple answers to these questions, but i have tried looking at its technical info and just got more confused.
