Adjusted COP dwell a point or two. Engine tune is coming into focus. Looked at the tables and looked at the 3D maps. The ignition table is looking good, but the VE table is rustic to say the least. Looked at the data log and it confirms where there is VE table tuning to do. Smoothed the table (expect further changes) to get rid of some of the rich feeling swings. Will be testing in the near future. I modified the VE table with the thought that as the engine RPM goes from a low RPM to a higher RPM, the VE table cell values should increase, and when the engine load goes from a low to high load, the VE Table cell values should increase (adjusted the cell values manually - table smoothing still not quite understood).Here's a pic of the tables in 3D view:<img src="https://speeduino.com/forum/download/file.php?id=12721" alt="VE-Spark Tables 11 Mar 2024.jpg" class="fr-fic fr-dii fr-draggable " style="" /> VE-Spark Tables 11 Mar 2024.jpg (82.81 KiB) Not viewed yetNoticed that the TPS signal is not what I would expect. For example, engine RPM 2800 or so, no TPS signal. Will be investigating.</blockquote>
