can anyone shed some light in this, im nearly ready to put my car back together, I was all set to purchase a gotech mfi pro for my 2.0 zvh, spoke to a local tuner and they have had nemerous bad experiences with it, saying the ecu never does the same thing twice. Was a bit of an over statement but his point was that the map was all over the place and the ecu even openeed the injectors at random times. I am now considering dta s40pro. If gotech if very good and this is a one off case here it failed, can anyone offer any advice
