I have gen 3 5.3 4l80e has JFR 218 cam. Have it setup in SD for for ve tuning got Idle and drove it to work 3 days and made adjustments based on afr error. Once it was close I multiplied by half. Then I tried to interpolate between 400 and 4000. Drove a block or so and wb was reading 16-17. Went back to good version of tune and tried smoothing whole table rather than interpolate and it did better most cells plus or minus 5. But did have few cells hit plus 25.
If this in wrong section please move.
My question is what's best way to get ve dialed in. Hate to make small changes and then table has spikes and engine stumbles.
Thanks. New to tuning this my first attempt
