[sainz911]

Hi, I'm in Italy, scuse me for my English.
I have buy a aquamist system 2d, and I want install this on my mini coper s 2005.
I have see the beautifull installation here in this forum, but I have any question:
In the aquamist box I have 3 jet, 0.7-0.8-0.9
What jet I can install? and at what pressure? (I want use 50% water 50% methanol)
And the pressure sensor where can I install? next jet is good?
last question, what is the difference if I connect the two wire (red and green) at the fuel injector o if I connect the red wire at 12v switched?
