Ok this is seriously driving me nuts..... My problem started last week I put race gas in uploaded my race gas map and went for a drive lean cut was off so I am watchig my a/fs just to make sure everything was good I started going really lean lilke 15 16 17:1 so I let off thinking my plugs were bad. I gap a new set and throw them in same problem. So I stard adding fuel to my boost columns I mean alot of fuel same problem. Now I am at the point I have a fuel system problem so I check my pick up it checks out ok. Next I check the filter checks out ok. Next I try a new fuel pump same problem. Next a new set of injectors same problem. Next tested the fpr same problem. So now I move on to well maybe the gas is bad so I drain 10 gallons of race gas out of my car put pump gas back in load my pump gas map same problem. So now I am thinking 02 sensor so I try a new one same problem. So now I move on to the ecu....guess what same problem! I am now running on my pump gas tune with fuel values way higher than they should be and still the same problem. I have redone my map and I am using the newest version of kmanager... Anyone have any ideas? I have attached my datalogs and map from today, I was looking at the injector ms box and I guess its how long the injectors stay on? I dont know its in red so does that mean its bad? would a bad resistor box cause this?
I am glad I have friends with extra parts to try haha

You've already stated that you swapped ecu's and that you ruled out the ECU, so it is not a K-Pro problem. It must be something in your setup that is causing the problem. What changes have you made recently?

I have not made any changes, the only thing I did was put race gas in and upload my race gas map. What about the injector milisecond thing? is it normal?

So do you have a datalog to compare to before you made the change?

There also appears to be a problem with your O2 sensor as it keeps going form "normal" readings to "0".

where does the 02 sensor read 0? and ook at this log right after I put the race gas in and changed the map. I do not have an old log befor the switch

I always run in open loop if that matters cand I saw where the 02 voltage goes to zero

Todd have you tried verifying these AF ratios with another wideband independent from Kpro? I would have expected atleast a knock with 22 psi and a 19.32:1 AF ratio! Is your knock sensor enabled?

haha yes the knock sensor is enabled, I have a brand new 02 sensor I will try tomorrow. And no I need to borrow a wideband
