01 / GUIDE
Confirm the actual controller
Start with the product label, hardware revision and matching manual. Similar names across listings do not confirm the same manufacturer, hardware or supplied package.
02 / GUIDE
Compare channel strategy carefully
A description of original and additional injectors does not establish a sum of independent channels. Confirm which operating strategies the exact controller supports and how the channels are used in your installation.
03 / GUIDE
Check signals, wiring and software
Discuss the original ECU, airflow and trigger signals, harness pinout, tuning interface and computer system together. An apparently larger model name does not establish compatibility or a better result for every engine.
04 / GUIDE
Get an itemized configuration
Request a separate list of included parts, required additions and optional accessories. Submit your original ECU and engine details with your inquiry.
Checklist & example
- Record each controller label and revision in a separate brief.
- Record channel allocation and trigger / signal requirements for each.
- Request separate wiring and contents lists; do not merge packages.
