OK so I think I've worked through the earlier issues. Thanks, Victor, for your help. I've now imported the stock 392 VE tables into my 5.7-derived system, and with the correct cam training values the entire VE operating range is running much closer to where it should.
I'm now trying to get a set of trained tables that more closely match what I request. I've tried using the log data and doing a "Paste Special -> Multiply by %" and then manually smoothing out the tables (somewhat) before exporting. So far, the resulting tables change by the requested amount in some places, but often only change by a percent or two. For example, my idle region needs to drop by around 10% in the fully advanced table (using LTFT+STFT, the fuel trim shows -10% in the idle region). The Trainer result only gives me around 2%. I'd guess that if I try to force a larger change, it may skew the table in other areas, or it may skew the other tables...
So the question is - are there any tips or tricks to get a more accurate set of results? Here are some options I may try but hoping a tip might save some time...
- Start with a "Paste Special -> Add" OR
- Double the fuel trim error and do a "Paste Special -> Add" or "Multiply by %"
- Make sure the tables are reallllly smoothed out before exporting
Thanks again for your help!
