It drops to a about maybe 14ish. Then when I get off throttle it goes right back up to 21. The car has 680 injectors.

The car just got an EVO IX turbo added last week, but I dont think that should make an issue while its at idle. But yeah we just did a swap the turbo for him.

 

Mine started at 14, then worked up to 21 and stayed there.

For real though, just go out and wiggle the cable. If the numbers flucuate, then you need a new sensor cord.

ALs, you should just email zeitonix. The guys always answers hella fast.

 

No luck on the cable wiggle. It holds dead solid at idle at 21.

My logs look as follows. This is from the drive to work.

It looks as though the injectors are scaled too big. Your idle fuel trim is maxed out (150 - In the latest release of Evoscan high and low fuel trims were mixed up). The 680cc injectors should probably be scaled around 570-610 depending on latency settings. I have my 780cc injectors scaled to 713 and from what I understand that is towards the high end of normal. I would work on rescaling the injectors to get those fuel trims in check.

The injectors are scaled to 585

 

Do you possibly have an exhaust leak? That can throw off your reading depending how big of a leak there is.

 

I may have one at my Down pipe.

 

I asked you to pull your STFT with a pocketlogger.

You need to know what the ECU is trying to do.

You need to know if it is the WBO2 or the narrowband front sensor.

Without the STFT you will not be able to figure this out.

 

Well I dont have one and no one local does either so I had to order one. They dont do same day delivery. LOL

 

You can use Evoscan to get short term fuel trims, although MalibuJack's Mitsulogger has it in a more usable form. The O2Feedback is the short term fuel trim.

-Paul

 

Well here are my O2 Feedbacks.

Clean MAF wire with alcohol ?
nevermind, that would make it richer

o2 bad?

 

O2 feedback looks good. It looks to be the wideband that is bad or the wire like someone else suggested.

When I first picked up my new car it was showing 18-21 afr on my zeitrionix on start-up. It was also idling very rough and throwing a check engine light for the front 02 sensor. Replaced the sensor and still had the issue, Torquefreaks did some work on my car and found that Al had scaled the stock injectors incorrectly (680). Fixed the scaling solved the check engine light and fixed the idle issues on my car.
