If I got a Nistune board fitted to my NA ECU - fuel/ign maps changed to standard TT spec. Will there be any unforeseen problems? My thoughts are that the 3 stage fuel pump on the TT chassis with an NA ecu might be a problem. Can anyone confirm? Its just more convenient to get the Nistune fitted to my spare ECU and then keep the stock TT one as a spare (spare TT ecu more useful to me than spare NA ecu)
Didn't touch it. I used to use it as a temp exchange unit while I did a PROM extract and socket of the PCB.
If you don't add some turbos, change your injectors and fuel pump to a TT spec then I think you will have some problems.
Then all you lose is control of safety boost solenoids and run your tt pump at only the higher 2 settings. I'd bypass the fpcu tho.
