What the Engine section is for
The Engine section in ESP (under Main Setup) is where you describe the engine to the ECU. The goal at this stage is modest: get the engine to fire and settle into a steady idle. The car won't be ready to drive when you're done, but it will be ready to tune, which is where the tuning guide takes over.
You'll get more out of it with a basic understanding of fuel, ignition and trigger systems, and some comfort using a Windows PC. If you're new to any of those, it's worth reading up first, or having a tuner handle the first start.
The four pages, and the order we use
| Page | What you set | Why it matters |
|---|---|---|
| Main | Engine type, firing order, capacity | Everything else is calculated from this basic description |
| Trigger | Trigger pattern and sensor setup | Without a clean, correctly configured trigger, nothing fires at the right time |
| Fuel | Number of stages, injection mode, tuning method, table selection | Decides how fuel is delivered and how you'll tune it |
| Ignition | Coil arrangement, coil charge settings, table selection | Matches the ECU to your coils so they fire correctly and don't overheat |
We work through them in that order. Main comes first because it's the basic description of the engine that everything else builds on. Trigger comes next because the ECU needs a solid RPM signal before fuel or spark mean anything.
Tips from our first starts
- Double-check the firing order. A wrong firing order will stop an engine from starting, or make it run terribly, and it's easy to miss.
- Confirm trigger sync before adding fuel. Crank with injectors disabled and make sure RPM reads steady.
- Be careful with coil charge settings. Too much charge time can overheat coils and ignition drivers. Use values for your specific coil.
- Verify timing with a light once it runs, so the ECU's idea of timing matches the engine's.
Save a copy of the map after each page. If something goes wrong, you can step back without starting over.
Running a Nexus ECU instead? The same ideas apply, but NSP organizes them differently. If you'd rather have us set up the base configuration, book a free consultation.
