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 :(

    • Nissan needs to forget about building SUVs in every size possible and bring back the damn Silvia/200sx duo to compete with the 86/brz. Maybe with the Honda type r motor pointing the right way
    • Good to see you followed your heart, got your dream car and have it pretty well sorted out now. I think anyone can get caught out with a seller not being 100% honest about a cars problems. Can relate to all the electrical issues, had similar issues with my first car (mk2 escort) ages ago
    • I just bought the Nexus S3 for my gtt, haven’t installed it yet as I’m collecting parts to do everything at once…so far spent $14,000 The Nexus is nearly future proof
    • Honda's hybrid system can be easily scaled up to PHEVs. Series hybrid at low speeds, at higher speeds the engine directly drives the wheels but there can still be some power bled off to charge the battery + the electric motor can still provide parallel assistance too. It's really only a question of will at that point. Toyota's PHEVs are selling incredibly well at the moment because of the flexibility. You can run on EV mode when it makes sense, but if you're planning on doing a long highway drive you can still fire up the gas engine and not have to worry about dealing with the rather miserable state of public charging infrastructure.
    • Only reason to keep a MAF on your RB25 is to be able to easily calculate true VE if you know what the factory voltage curve represents in grams per second of flow. Also allows you to do things like pull the original OEM ignition + AFR target tables and use those as a starting point for your base map. Once you're well and truly done tuning though there's no need to retain the MAF.
