Im pretty fluent in code, Mostly x86. For anyone trying to understand the concept of a computer running assembly I would suggest first learning any program language then going here.

I do however, have experience in the installation of aftermarket mobile electronics such as alarm systems, remote starts, audio systems, and cruise controls. I plan to contribute these skills to this board whenever I can. |

Yes its a chalenge, unfortunatly the number of people with the skill, dedication, time ( your looking at hundreds of hours even for a skilled person) and who probably own a brz\86 and want a carb legal flex tune who would do that sort of work for little or no return will be an extremely small set of people. If you want to progress that id suggest that you contact ECUTEK and ask if its possible. They will probably want to know how big the market would be for carb legal flex tunes before committing resources to the project i would think. |

Ok if you go ecutek latest racerom version 11 It allows the flex sensor input to be the rear 02, evap pressure or the MAF ie mas air flow sensor. Now you usually need maf for metering incomming aor to engine but in ecutek its also possible to use speed density method . Speed density uses the MAP ie pressure sensor and intake air temp to determine air flow in engine So theroeticly you could repurpose maf sensor to flex, and use speed density tune method This would leave both the evap amd rear 02 active for emmissions tests. Now the downside may be speed density may make throttle response a little slow at low rpm, and it may or may not allow tuner to fuel engine well enough to pass emmissions standards, who knows but its theoretly possible with ecutek at present |

Wait so ecuTek for 2017+ doesn't really require the evap pin? You have the option. To go for the O2 sensor also?

Yes ecutek can use rear 02 or evap connect flex kits on all models incliding 2017+ Opensource only supports evap amd only pre 2017 |

Do you think I can just tap the O2 sensor or does that requires a different voltage gauge? |

Voltage range is same rear 02 or evap, howver you will need ecutek to use rear 02 input for flex , unless your rewriting ecu code |

I went with the 0.5 - 4.5v range. So I just need to tell them that range and I also believe the rear 02 sensor has three wires (White, Black and Blue).. Do you know which one receive and send the voltage? ( I believe black would be the ground) Thank you. |

rear o2 has 4 wires, 2 on top are for heater, just leave disconnected
the blue wire on bottom is the positive if I remember correctly To then scale and use the sensor on any input port, you need a tuner to do it, or to buy a Racerom license to be allocated to your kit |
