Ok, this is weird, after steven did my fuel map for me i adjusted timing a bit to avoid knocking, i dont get that many knocks wich is good. Here is the weird thing thats happening. So i originally wanted steven to help me with my fuel map cuz i couldnt seem to get it below 13.3 or so in boost so he helped me out and made me a sweet fuel map, the map is not the issue at all i dont think, but my car switching into open loop is it seems. I set my "open loop throttle 1, and 2" tables to 40% throttle and i set both the "open loop load tables 1, and 2" to 50% load hoping i would see the fuel getting real rich way before i got into boost and its weird because my wide band goes from 14.8-15.2 (normally sweeping for 14.7) to 16.4-17.0 AFR instead of getting richer!! im not getting much knock, and evoscan tells me when i logged the AFRMAP that in open loop the AFR values drop from 14.7 and taper down to 11.2-11.5AFR....WTF is going on??? Here are some logs of short pulls:

Here is the youtube video i just made now to help you visualize, sorry i cannot spell at all

P.S. dont mind my broken volt gauge, it shorted out somehow and now only reads volts when the car is off lol
Also the LTFT mid, and low are at zero because i just flashed the car

 

what happen to your logs? I was going to scope them out for you but they dissappeared

 

I changed my timing maps, view the log i have up there now, 5psi pull and please view the video! not sure whats going on here :-(

 

Can you log your WB? That helps extremely with figuring out this type of issue as we can tell exactly when it starts going lean. Your IDC and pulse width both seem to be raising nicely as you progress. Just as you said the AFRMAP shows the afr progression to be nice a smooth.

At what rpms is this happening roughly? I see your 02 voltage drops to 0 then from 2500-3500 it pops back up transmitting voltage almost like it went back into closed loop during that time even though your feedback trim stayed at 0

 

I first need to find out how to log my wideband via rear 02 sensor, by disable the rear 02 perifery not sure how to do that tho. Yeah its so weird AFRMAP shows fuel getting more rich, but as you can see in the video as soon as i start boosting (2,800 rpm's) ARF climb from 15.2 up to as high as 17.5 one time... Also i am not sure whats going on with my front 02 sensor, it randomly will read voltage at idle sometimes, and sometimes it wont, i bought a new front 02 sensor im putting in this weekend. Another thing to note, i have really low open loop table values, open loop TPS% at 40, open loop load% at 50, but still it seems as if i cannot get into open loop, or its like reversing or something

 

You can see if its an issue with open loop by doing this.

Go into both open loop tables and set every rpm to 10. This will make you run forced open loop. Then flash that and do a run. If your lean issue disappears then we have something to go on. If it does not then we can rule out an open loop issue and you can flash back your other map and move on to something else.

Also. you dont have to do the disable rear 02. You have the aem uego correct? You can just wire in a serial port off your guage and then get the serial to usb cable and log it like that. This is what I do and works great, bought a cheap ebay serial to usb cable for $3 shipped and it has been working great for a year now.

 

This is prob what i will have to do! But i would like to disable it anyway, i cut the sensor off a while back and i have a code for the rear 02 anyways. I will test open loop tomorro morning, also these are the other logs if you would like to view them :

 

Ok so far every log of yours I have seen has the same trend. That 02 reports back voltage from the same rpm range 2500-3500. I dont see anything in your TPS to suggest why this is happening. Post a log after you run the forced open loop so we can see whats happening.

 

Will do, expect a log posted in the morning, also, my TPS at idle reads 13.2% or something without me pressing the pedal, shouldnt it read 0%?

 

i recently learned that on mitsu's the tps will read within that area when youre not on the pedal...mine reads 12.3%

 

It is very simple really...if you are reading lean under boost it is either real...or not. So keep trying to check it by going WOT and let us know how it turns out!

 

Sawulkn is correct. You will also notice that you probably will never hit 100% TPS either. My throttle at complete WOT is 93.33%.

Also another thing I noticed too is your only going maybe half throttle. If it is an open loop problem it could be simply due to this, maybe look at what your throttle open loop settings are in the 2500-3500 range, they could and probably are higher in that area causing it to switch back to closed loop. the obvious way to test that is give it more like 70% if your still nervous about WOT

 

is a aem air fuel gauge good?

 

Yup mine works mint and very accurate. I wish it would have came with a cable to log like others but making one was much easier than I originally expected

 

I thought that too, thats why when you suggested a forced open loop i thought it was a good idea, so here it is, another video because i cant log wideband yet, but also a log to go with the video, evoscan tells me its in open loop because 02 sensor feedback % was always at 0% but my AFR were 16.3+ its so weird.. Heres the vid and log i hope you see something i dont
