In the manual, it shows pin 11 rotor 1 injector and pin 12 to rotor 2 injector. It then shows pin 10 to both staged injectors. Is the wiring for the secondaries correct- only one wire to both?

Thanks.

Hi Dan,
This is ccorrect for both the Wolf 3D 3. and 3D 4. series ecu's...

Ref: Wolf 3D 3 - page 77, 78
Ref: Wolf 3D 4 - Section 5.4.3.10

Thanks, Gregg. I guess it would have been more helpful to list the version... It is the V4.

The wiring seems confusing to me. Wouldn't you want the injectors to fire independently, or am I missing something here?

Hi Dan,
The primary injectors are wired to fire individually so as to give accurate measures of fuel at low and medium throttle settings and engine speeds, but as rpm increases, the seperation between individual fuel injection pulses shortens and the need for that high degree of accuracy is reduced, so we can now bring in (stage) the secondary injectors to supply the additional fuel needed. The high rate of airflow and the nearly continuos firing of the injectors makes the need for seperately firing secondary injectors unnecessary...

Makes sense. Thank you.
