On first installation of a PFC, I use the Commander to;

1. check the water temp gauge calibration (where are 50/60/70/80 degrees on the gauge)

2. the boost gauge correlation (do they agree)

3. the alternator charging (battery voltage)

4. the throttle position sensor (am I getting 100% throttle when the pedal is to the metal)

5. the tacho correlation (do they agree)

6. the speedo correlation (do they agree)

7. the AFM cleanliness (is the voltage increase somewhat linear with rpm or does it jump all over the place)

8. check that the ignition timing is actually what it is running (using a timing light)

If I am tuning ignition timing, I run only knock display

Nice and large, very easy to see if changes in ignition timing (advance) cause knock

If I am tuning A/F ratios I run, injector duration and knock

Nice and large, very easy to see if changes in A/F ratios (leanness) causes knock and exactly how much injector timing I have left.

Generally I run AFM voltage, inlet air temp, injector duty and knock, as they are not covered by other gauges. Personally any more than 4 displays and I find it hard to read them while driving.

:( cheers :(

    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
    • Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.
