Scary VE area

Don't mind at all... really appreciate the help. I agree with everything you are saying about numbers and AFR. It appears that my VE is way lean Higher RPM 40-50KPA range. I don't know exactly what numbers are at this point it appears to be about 15%,but I know I need fuel there because the AFR is lean. Whole point of the post is do you guys agree that I need to move the VE in these areas and how would I smooth this into the rest of the VE?
LOG File
On a second note I have lost my WB. It has lost both analog outputs. Gauge still reads but getting flat .8v output to the MPVI. Verified by reading raw voltage in HPT scanner and via a voltmeter. Even tried forcing a steady 5.0v output via the WB interface and same .8v out. Didn't measure the analog out V for the PCM narrowband simulation but its logging flatline low also.
Done tuning for a bit, and will be in the market for another WB. I have read enough bad press about the LC1 that I will be getting another brand. Anybody recommend a semi permanent unit that will also narrowband simulate has a good gauge to go with it and is HPT friendly?

PLX just came out with a cheap new alternative...havent seen it in use other then at SEMA though...as for your innovate I would suggest talking to them to see if you can get a new one from them..they are pretty good at the fixing/replacing end from what I've heard.

aight the three main problems I see
1. your logging 25 bytes worth of info on a 48byte max what happens when you do that is you only get 5 frames per second which isnt very good resolution...since you have your trims turned off you could always delete all 4 of them and be well under the 24 byte cutoff
2. and this stems from #1, but not limited to #1...12 minutes worth of logging isnt nearly enough data...Im assuming you have the stand alone unit so just bring it with you & log about an hour to an hour & a half of data @ 24bytes or less of data & use that to populate your VE & report back.
3. if your wideband is dead now who's to say it wasnt on its way out recently?

PLX was my first choice but went with LC1 due to it being a little cheaper. Gonna give the PLX unit a shot.
Thanks for the input.

2> Maybe I am completely wrong with my tuning strategy. I have hours of logging in that VE so far. The very light throttle stuff and the VE is falling in place in those areas. After hours of logging and tuning it I decided to TOUCH areas of the VE that I hadn't IE: some light throttle run through the entire RPM range. That is what that log represents. I saw a very bad spot and stopped to ask people that know more about it. I've been there a total of about 5 pulls and all show similar AFR I am not going to log it for an hour. I am going to touch upon it as I have and adjust it closer then I will log it longer to fine tune it in.
The way you make it sound is that without 1000 cell counts you don't touch anything even though its obvious that the VE is way out of line.
3> It reported steady believable AFR reading by gauge and logging up until today when it just quit outputting after I calibrated it. Still giving the same data via the gauge just not out the analog outputs.

I will be talking to them and hopefully get it fixed. It will then go on e-bay for sale.

In the screen shot, 43 hits in the cell count. I also saw the same trend in a 2nd gear pull up the range. Notice steady state TPS% and where the AFR is.

Did make me go back into the log to look at the setup. I have been messing with config files so though maybe I might have left in the PID for a 1 bar map. Here is another shot of a 1st gear pull. Yikes lean.
