I just got new motor running today. Trying to scan to adjust fuel trims, and all I get in LTFT and STFT are 0's in the Histogram. Everything else works--Main Spark---Timing Advance, Knock Retard, Narrow Band 02's are reading. LTFT and STFT read 0. What is wrong? Scan attached.
If I pull up an old scan from last year---LTFT and STFT have readings. My new scan today just 0.

Making some progress, but still need help. Loaded an old scan config this morning. Same results---LTFT and STFT show zero all during scan---everything else works in Histogram and Table Display---but I know I have something missing. I am attaching a copy of my tune, scan config, and two scans from this morning. Any help will be appreciated!!
