    The key on, engine off fuel pressure for a 1997 Camaro 3800 is 48-55 psi. With the engine idling, the pressure should be 3-10 psi less than the key on, engine off pressure. This is from my ALLDATA.

    The 2000-2002 3800 has the same fuel pressure spec.

    Is there a link to the WOT 4.3L tuning? I'll be needing that soon when my Marine intake comes in and I can install larger injectors.
    Thanks,Scott~

    The basic principals to tuning most engines is the same, but the process is different even from similar model car to similar model car. Half the fun is finding out what works best on your setup.

    3.4-2.6" PB Quick Change pulleys, Custom CAI, XP Cam, N* TB, LQ4 MAF, SLP headers, 42.5# Injectors, 180/195* thermostat.

    13.501 @ 103.392 on 91 (2.4 60-foot).
    13.82 @ 105.28 on 87 octane! (2.42 60-foot).
    263kph top end as shown on the GPS.
    All this and 39MPG to boot. What more can a man ask for?

    the 4.3's have a V8 pcm so can actually utilize most of the V8 tuning concepts.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Have been an HP Tuners customer for a few years. The program works great and it has allowed me to complete a 3800SC engine swap without a problem. Have been able to scan and make adjustments. Engine is running good but you can't optimize from the drivers seat.
    I am looking for a experienced dyno tuner in the Central/Southern NJ. Eastern, PA area that can optimize my tune and take it the rest of the way. Having no luck finding one so if anyone can recommend and expert to tweak my tune I'd appreciate the lead. dlagrua@live.com Any leads are appreciated.

    My guess is because it only use the VE table once the MAF has failed and is more of a limp home mode type of thing. The 3800 is a MAF based system and speed density tuning is not really required at all. I never touched the VE on mine.

    Not required till the maf fails lol I think this is crazy to not tune the ve but everyone has a different opinion. And yes it's maf based but you didn't answer my question sorry. Also if running full open loop there is no maf diag as mine does not diag maf failure do to no ltft or stft is my understanding. But if there's a way to enable ae enrichment and decel then these cars would run perfectly fine with no maf

    You'd still only have a VE up to 5.8psi of boost, what's the point in running speed density when the VE can't even do 10psi or higher.

    With the way the tuning is set up with pe it doesn't really matter can work just fine but this is not the thing I'm getting at I already no that everyone feels that way I'm asking y can ae enrichment and decel enleanment not be enabled well in speed density if you don't know don't answer what ever happened to helpful info

    I’m reading all kinds of stuff about wideband O2 sensors, but I don’t find a write up about what kind of sensor and how to hook them up. Or for that matter, how to use them specifically

    The $160-170 AEM wideband, then wire it into the cars EGR circuit or into your PRO interface if you have it.

    There are youtube video's about wiring in the wideband to the EGR circuit. Maybe you aren't searching the right words or aren't using google with "hp tuners" after you words. That's an easy way to find information. The VCM scanner section sticky pages also has write ups for logging the wideband.

    Plan and simple the wideband is used for air fuel ratio corrections and to monitor the fueling. You use the wideband readings against the commanded fueling to find the error between the two and correct the airflow model.

    i just tested them and all of them except the very top link still work.
    unfortunately the top link is tied to a non-hptuners site and it is no longer a valid web address.
