got the ve running, good idle and set f/p at 3 bar with tomei 740cc injectors. road test and as soon the lobes switch the car is leaning out bad. up the f/p and the samething but bad idle. i think i need the right program for the 740ccWhat program? just 72's N/A..... 3bar.. 4bar... what maf... If you give a little more info I could let you know. I currently am working on 2 cars with 72lb programs.. and have some experience with a few others
72lb program 4bar
who has a tune for a turbo ve ? meaning plug and play60lb injectors at 3 bar are 70lb injectors at 4 bar. If you have a JWT ECU setup for 72lb, you simply add 1psi more of fuel and you should be all set. You will basically set fuel pressure for 59psi-60psi.
Now, that has NO bearing on the issues you are having. You are going lean because you don't have a tune for the VE. THe map really needs to change when the cam turns over to adjust fuel for the increase in air the cams are allowing by holding the valves open longer.
