1) If I didn't use a second MAF on would the ECU automatically adjust the pulse width to adjust for the extra air or would the ecu have to be re mapped?
1b) If the pulse width were increased would the duty cycle of the injectors get too high (aka above 80%)
1c) Would the stock injectors be able to handle a pressure rise to create a higher fuel flow rate to account for the extra air?

2) If I were to get my hands on another MAF, is it possible to wire the two together to get a proper air flow reading? (Take into consideration this is an OBDII '97 ECU, I know LAN has this mod with his ECUTUNE but that won't work for my car and I can't afford the standalone ecu just yet)


I figured that once the car is running in a closed loop system as long as the injectors would be able to handle the extra duty, the ECU would automatically adjust to account for the extra air, changing the injectors wouldn't really help me, cause I would need to reprogram the ecu anyways because its' open loop tables would be way off.
Um, something, something, something, NO. I guess you have been looking at something like a JWT for the 300zxtt to get these ideas?
