I have started with VE tuning the car. I have read conflicting opinions on reseting the fuel trims. Everything says to reset the fuel trims the first time. From there I have read not to reset the fuel trims after updating the table and starting a second scan, basically not reseting the fuel trims again throughout the iterations of VE tuning. On the other hand I have read that it is necessary to reset the fuel trims after every update to the VE vs. RPM vd. MAP table, along with a decent drive and a few restarts in between. I have been getting a good LTFT scan in SD mode on my drive to work, updating the table in the editor, uploading the new program, then getting another LTFT scan on the way home, updating the table in the editor, uploading, and repeating the following day. It appears to be closing in pretty well, but I am wondering if it would be better to reset the fuel trims and give the car "learning" time between scans/updates.
