Hey everyone..I did an aristo 2jzgte in a na 94 supra auto. using the aristo ecu,map, rewired and extended harness to fit na, aristo turbos, injectors. I have custom 3" piping throughout without the o2 sensor installed. I havn't installed the walbro fuel pump yet nor did i do the 12v mod but the car should still at least keep idle and drive!!! i was plannning to do the fuel pump and 12v once the car gets running and smooth. The car starts but does not keep idle, instead it just shuts off. The car runs Richer than bill gates and causes a whole lot of black smoke from the exhaust. It keeps idle when it's cold and cooled but once i drive it and get speed and boost starts..the car just dies out and does not want to idle. And for some reason the comp is throwing a maf code when i dont have maf but instead i'm using a map from the aristo 2jgte. Pleaseee help i've waited too long to finish this thing and this problem is killing me... any help will be appreciated.
