VE Learn Q?
Seems all of last season I was getting meaningful changes in my VE tables with VE Learn "on".
This year after adding a calpack that was missing it appears two things occurred.
1. My tune went way rich. My BLM's are bottommed 108-110. That may be expected as last year could not pull VE values 2800-3200 RPMs mid MAP under 100 unless I raised BPC significantly. Also my OL RPM coolant map tables likewise had to be enrichened to get lower temp coolant A/F to approach necessary enrichment as evidenced in WB.
2. VE Learn is not making significant corrections. I dont know why. I am using last years (non-calpack) bins and I expected major pulling of fuel. Not happening. If fact I question if VELearn is functional? I use the bin to learn from as the one that is in ECU and comfirmed my Prominator new bin is created as 05192008_NEW. simple! after it is created I rename it and do compare in TP. Looks same. Corrections are inconsistent and a cell goes like from 66% to 66.5. 25 minute cruise 1000-3000 rpms 5-75 MPH. I dont understand what I may have done. I will do another this evening and have already removed 10% from both VE tables manually.

Re: VE Learn Q?
For the VE Learn be sure to disable HiWay mode. Then double check the WUD Preferences for learn. BLM mode along with the temperature window values.
If you have a data log you can run VE Learns via PlayBack mode. Set up the learn session, then play back the log file, and crank the playback speed up.

Re: VE Learn Q?
I think I might have figuered it out.
For reasons unk the datalogs were being saved as a file not a datalog(.dat). Would that do it?
All settings for BLM update and INT update are same as EBL.bin. HighwayMode I believe is still disabled. I will double check that. The created NEW_.bin appear to be functional and show same values as the bin I learned from in tunerpro. Odd thing is that last year it was working well. Car was in shop for two weeks so my first logs were this week. I dont think I changed any "preferences" in WUD. Honestly I did not know they exist. I will look there. Thanks.
