Would greatly appreciate any support from someone that's connected wires direct into the ECU |

Did you unplug connector from ecu then try inserting pin ? |

Check the tab thats supposed to spring out is not bent inwards, somtimes this happens when its removed from old connectotor housing, you might have to bend tab outwards again |

Its highly unlikely that anyone like ztan is going to develop an opensource flex fuel tune for the 2017+ cars. It requires someone with a high level of skill to spend hundreds of hours of their time to develop and risk possibly bricking their ecu ( ztan bricked one) , and then give the work away for free. Ztan was extremly generous with his time If you want flx for 2017+ in the forseavle future your going to need ecutek |

I am willing to try.
Im just curious how ZTAN is dissembling the hex. By hand or is he using a program? |

I’ve been wondering if anybody has the coding skills to remap one of the unused pins of the ECU for use as the ethanol content sensor input so that we here in the US can get a flex-fuel kit that has the potential to be CARB compliant. Instead of substituting the ethanol sensor for the rear O2 sensor or the evap pressure sensor, which automatically disqualifies the modification from being compliant, to adding the additional sensor where there wasn’t one before. I would take this on personally if I had coding skills, or would be willing to supply someone with a spare ECU for research and development and would gladly help to pay to get this project started. Would anyone else here be interested in this?

Id say coding to unused outputs would be extremely unlikely, not even ecutek do that and they have full time coders. It may becunused inpits\outputs not wired out or that to code extra inputs\outputs is way more difficult than just repurposing existing inputs\outputs. Even jist altering ecu code requored a hogh level of skills and a lot of time |

What "existing code"? "as easy"?
People have access only to binary firmware dump from ecu, then there goes low level disassembling, no documentation, no comments, no source code and alike, one has to do lot of guessing, going by hunch, trial & error (including results like bricking ecu, or crashing), "coding" is in low level, especially more so if you want to code something extra, most of "tuning" happens to be by tweaking values in some found tables, not adjusting code that works with those. It was major PITA to add extra functionality/custom codepaths for E85/forced induction/LC/FFS and alike, a bit better for paid team of devs @EcuTek, much harder for single enthuasists doing for free at limited off-work time such enormous low-level work that requires much higher skillset then generic coding in higher level languages if one had access to original source code (most probably no-one outside toyota/subaru ever will, to not ease tampering with firmware for legal reasons, including emissions certification and such). Have you ever done yourself "easy" coding in assembly for undocumented existing binary firmware that works on undocumented hardware set (including mentioned extra input/output signal pins)? |
