![]() I just did mine this morning PDXREALTOR and had the same problem.
I deleted the check engine lights listed above, and the first post had a pic of accesstuner with the cells at 0 | 5 0 | 5 I changed them to 0 | 5 10| 19.75 and it seems to be reporting correctly (or very close to)

![]() Is there a 4th ecu input wire I could use on a 2005.5 obxt? Some other sensor wiring like the uppipe EGT, pcv anti-tamper bridge, purge solenoid, charcoal canister sensor, etc. *or even front o2s* so that I can AP datalog all 4 channels of the AEM 30-2340 4 channel uego?
Thanks Matt |

At idle my AFR's reported on the AP was around 15.0 while it was 14.4 on the gauge. I had to massage the numbers a bit to compensate for the difference. |

0|5 10|20 Respectively in accesstuner and the reading was about a full point off like yours, aem gauge read something like 14.7 and AP was reading the wideband at like 15.5. I came across some other numbers online and after trying a few with no luck I just did the same and worked them until it read fine on my end. Might not be perfect, but as long as its reliable and holds there I can use it to tune my upper maf scaling for open loop, then adj POL fueling table to dial it in Mind to post up which gauge you have and what you had to use in ATR to get it to match up, in case anyone else needs it? |

![]() Mine ended up reading .3 higher in btssm than what actual wideband gauge reads. As heiche said he thinks the rear O2 input is slightly biased.
Read my post user name makaveli in the legacy forums below. As long as the scale is keeped to the linear scale, (changes at both ends of the scale it) matchs the gauge perfectly. http://legacygt.com/forums/showthrea...16#post5538116 So going by the AEM info: 0.00 volts =10 AFR 4.99 volts =19.98 AFR So i pulled 0.3 from both min and max afr otherwise the scale wont be straight as they show you it is ![]() Last edited by my9999; 08-02-2017 at 11:07 PM. |

![]() not sure if it's been covered or not, but i just ran into this issue: 06sti with aem wired into rear 02. reads on ap and logs fine, but it wouldn't go richer than ~11.4 no matter how much fuel my tuner added. the signal wire to the rear 02 was still intact, they never cut the wire downstream, just tapped the original wire. the theory is that it's still sending about 1volt to the ECM plus the signal from the wide band, preventing it from reading lower than the AFR actually was. the first test was to peek at my wide band gague during WOT. sure enough it was in the 10's while the "rear 02 only" was still 11.4. figured my options were: cut the signal wire to prevent anything from adding to the wideband signal, or disconnected the sensor to prevent it from being powered to begin with. I figure, the ECM isn't using this information anyway, since the input on the ECM has been hijacked for wideband datalogging... so I disconnected the rear 02 from the harness plug closest to the rear 02, and bam 10.5 afr WOT now.

![]() So I have a X-series wideband hooked up currently in my 13' WRX, I tried wiring the white output to the TGV right data cable (Red/White) just by piggybacking it. Had my tuner send me the adjusted map for it, and my AP is only reading either 12 or 15 under Sns Only TGV R. Its not in sync with my gauge nor does it change under boost.
Help? EDIT: When connecting Gauge output to TGV data cable, you must leave TGV cable not connected to the TGV or it will mess with the sensor. Last edited by Bickz; 12-18-2017 at 10:24 PM. |

![]() Would I still be able to use my gauge if i the wide band to the rear o2? I imagine I would just tap into the white 0-5V cable that goes to the gauge?
Also how does this affect smog? Last edited by Penguin_02; 02-10-2018 at 02:11 AM. |

![]() Does anyone have the correct scaling numbers for an innovate gauge?
Or, if they both use the bosch sensor would the numbers be the same? |

'Optionally, the YELLOW analog output can be connected to the analog input of other devices such as data loggers or standalone ECUs. If this wire is not being used isolate and tape it out of the way. The default analog output configuration is 0V = 7.35 AFR and 5V = 22.39 AFR.' |

![]() question here...so I'm running a V9 motor and the DP has two ports for o2 sensors because theres is no o2 on the up-pipe. so theres one located by the turbo and the other down the pipe like normal.....if I'm adding a Wideband like the one in this write up, should I add a 3rd bung and run it from there? or can I just use the rear o2 and maybe have the tuner take care of that code? or is the rear o2 important enough to where I should leave it in place? thanks for the advice and great write-up!

![]() A note for anyone reading this and wondering if you can still utilize an AEM (or other aftermarket) wbo2 when you have the Cobb Flex Fuel kit installed as well: you can!
The pressure sensor hijacks the RH TGV to output it's readings and the ethanol content sensor hijacks the LH TGV so those two options are both out. The other option to tap into for your wideband is the rear o2 sensor. You may think that that option is already taken as well, as I originally did, since the flex fuel module also connects to the rear o2. This isn't true. The module only intercepts the rear o2 sensor connector to steal 12v off it. It does not hijack or otherwise touch the signal wire so you're free to tap it for the wideband using the procedure outlined above. Hopefully this clears up any confusion anyone else may have had when looking into this. ![]() |

![]() For anyone thinking about doing this setup.. I did this exact same setup on my '13 STI, and it works great for logging. HOWEVER, I just tried getting a state inspection done this past weekend and my car FAILED because the o2 sensor says is "not ready".
If you live in a state that requires emission testing, this will also happen to you. |

![]() Pay for ATR only to find you cant use custom sensor logging.
Pay for dyno tune only to find your Cobb PRO tuner cant set it up for you. "Oh yeah you have check engine light" I give up |

![]() They don't allow custom sensor logging on ATR? Since when? I thought that was unlocked after the paid classes went into effect.
