Evening.
I recently purchased the MPVI2 interface and have been playing with my cars tune starting with the MAF. I think I had that dialed in decently, and have been chasing my tail with the VE table. Every write up, video, and post I see tends to say log the AFR error with the column Axis as RPM, and Row Axis as MAP. Drive for some time and copy/paste the data (half %) into your table in the editor. Doing this clearly changes the values in the table, but upon the next iterations, I will see little to no change in the scanner, and often the change I do see is in the opposite direction.
I have the MAF failed at 0 Hz. I have Dynamic Air shut off with High RPM Disable set to 10,000 RPM. LTFT disabled in the dropdown, and the Min ECT set to 283*F. Closed Loop Enable, ECT vs IAT is set to 283 for all cells. DFCO Enable ECT is at 283*F.
Mods I've done to the car previously have been Cam (TSP Torquer 2 232/2343 .600/.600 112), PRC As-Cast 225 Heads, Fast 92, Long Tubes. Car was dyno tuned. I added a 9" and true duals between then and now, so wanted to try and wrap my head around tuning myself. Using an AEM 30-0300 through the pro link to log AFR.
I don't know if I just have the file set up wrong or if I should be chasing a hardware issue (vacuum leaks? Wide Band Placement?) Hopefully I'm just doing something stupid.
Attached is my last tune file and the data log that came from it.
Appreciate any help or advice.
Thanks!
