Thomas Spagnoli: workshop approach for Royal Enfield Hunter 350 ECU remapping

I would treat Royal Enfield Hunter 350 ECU remapping as a diagnosis, not as a shopping list. The first job is to turn a vague complaint into a repeatable test.

1. Start with model, year, mileage, engine type, recent work and the exact symptom.
2. Separate opinion from measurement: voltage, pressure, compression, plug condition, code history and visual evidence.
3. Make a small checklist and tick it off in order. It is slower for five minutes and faster for the whole repair.
4. When in doubt, return the machine to a known baseline before tuning or modifying.
