Morphology
The particle 'up' signals increase and 'hot' conveys higher intensity, so a learner could infer a general sense of making something more powerful or intense. However, the specific mechanical sense of tuning or modifying parts to improve an engine is metaphorical/specialized (and could be confused with 'heat up'), so the meaning is only partly predictable from the constituents.
Etymology
Hot up (about engines and machines) comes from car and bike people who changed parts so an engine ran hotter and faster, literally 'hotting up' the machine. So it means 'to make a machine more powerful'.
