Where you will find it
Engine Bump sits in the Electrical area of the Nexus software, alongside Starter Motor control, Engine Control Relay and Alternator Control. At the time of writing, Haltech's own help text for this item says it is still coming, so there is no official description of every setting yet.
What "bumping" an engine usually means
In the workshop, bumping an engine means turning it over briefly with the starter, just enough to move the crank a little, rather than cranking it to start. Mechanics do it when setting valve lash, checking timing marks or lining up the crank for a job. Its location next to starter control suggests the Nexus setting is related, but until Haltech documents it we would not rely on assumptions for how it behaves on your car.
What to do before using it
- Check the starter wiring and setup first, using Start Motor Wiring.
- Treat anything that can crank the engine with care. Keep hands and tools away from belts and fans.
- If you are unsure what a setting will do, ask us. We'll give you a straight answer for your setup.
