How to make a stage 1 tune:

  1. Open stock calibration map in WinOLS

  2. Increase torque

increase torque commanded/targets

  1. Increase VE (Volumetric Efficiency) targets in multiple tables

  2. Increase exhaust temperature limiter

  3. lambda

increase or decrease lambda targets when tuning for more power?

  1. fuel pressure

more pressure = more fuel = more power, right?

  1. ignition timing

more timing = more power, right?

  1. and some small things

what might these be?
