I've been warned off the AEM sensors. The AFR500 is a direct replacement for the AFX, it even looks the same.

Hey Guys - I have a AEM Digital Wideband A/F (30-4110) installed, and had it hooked up to my previous P&L Header (had 3 A/F bungs)
I switched to the Open Flash UEL header, and didn't even think to remember to add a 3rd Bung. What's the best process to have this stuff hooked up? Is it: 1. Just take the header off and add a bung? 2. Remove one of the stock 02's and the tune can 'turn it off' ? 3. Play around with wiring and have all 3 signals coming from two 02s? Any help is appreciated. Thank you!

http://www.ft86club.com/forums/showp...6&postcount=40 dont remove or alter the front o2 sensor its the primary fueling sensor. if you want to add the wideband best to add the third bung and wire it in completly independantly. you could use the rear 02 sensor port and disable a few cel codes in tune and disable the AF#3 correction. Ot mabe remove the frontpipe and put in the third bung at the start of that some frontpipes i have seen have a third bung installed their.before cat |

Sorry to revive an old thread, but I’m going to be installing the AEM failsafe I just purchased but the pictures aren’t working.. I’d feel more confident learning visually aswell lol. Is there anyway you can update/ re-upload the pics you initially posted for the diy @Sportsguy83 ?

Do I Tap into pin20 (CPC input) with the 0-5v Analog output or am supposed to cut the wire on c20 and have only the analog output connected to pin20 ECU?

If your running ecutek you could just rescale the current front 02 sensor to read more wideband it reads quite reliably down to about 10 afr if rescaled. you can then feed that "wideband" afr into an ecutek custom map and use it for afr failsafe. cost is zero, no wiring or aditional sensor required |

Because of the variance I've seen in it vs a WBO2 at the tail. The variance in "trusted" O2 sensor scalings. The fact that at higher exhaust pressures that the readings change. It's certainly good enough to give an indication but I wouldn't say that it was accurate all the time.

How much variance did you see? It would also be interesting if the variance is the same between different cars (canned tunes). For NA it seems that the engine is to a certain degree pretty tollerant of varying AFRs anyway. I run mine at 12.2 in normal conditions, which is fine. On track it starts to FLKC like crazy (had -5 deg in one log). With 11.1 it has virtually no FLKC at all even on track. So with not too much logging it should be relative simple task to adjust the tune for whatever conditions the car is expected to be driven at. Or with Ecutek to make it automatically run richer depending on FLKC. I suppose this is kind of the same as what the stock MY17 tune is doing with "power AFR" just using a different input parameter.
