Deciding between eFlexPlus and eFlexPro

The eFlexPro is our premium kit and includes features not included in the eFlexPlus. Specifically, the eFlexPro comes with a wiring harness that includes two additional sensor wires. With eFlexPro, you also have more features in the eFlexApp and eFlexTuner software. More specifically, 3D maps (instead of 2D) let you adjust enrichment for both engine load and RPM.
