Message Ok so i know i need to take the mass input 1 and mass input 2 and then hook mass air output to the mass air wire going to the ecu. But i still have 2 questions.

What settinG do you use on the e manage? In the E manage software where you have the drop down box that you select your type of air meter from(in the back of the manual you look where it has the vehicle specific wirring diagrams and it has NS_HW-2 for a Z32 under skyline it has NS_HW-6 for RB26DETT) Which one of thse settings do i use? I know on my old AFC when using two intake on a Z You set the AFC for 2 inputs and ADD so it would add the two voltages together. For the RB26 you would set it for 2 inputs and AVE so it would have a average of the 2 inputs and send that to the ECU.

I don't think you would want to use the Skyline setting in the Greddy software since the Skyline ECU has two inputs and the Z only has 1. What can i do to make it add the two input voltages together and then output the total?

My other question is: What do i wire the plug to on the other Mass air meter? Do i tap the power and ground wires on comming of the plug into the power and ground wires on the factory mass air plug and then run the signal wire to the second input on the e manage? I need to know what to do with the wires?

ALso when i use the injector corection feature for upgrading to 555cc injectors will i need the optional injector harness? Or can it correct it through altering the incoming air signals?

Thanks
Shawn
