    Re: G force

    What model and year car do you have?
    The above post is my 2 cents....nothing more.

    Re: G force

    These chips "work" by fooling the MAF into thinking the air inflow into the engine is lower than it is. As a result, the engine dumps more fuel into the combustion chambers. The only thing these chips do is lighten your wallet via buying the chip and worsening your gas mileage.

    I asked this same question months ago... Haven't heard or seen any different answer... EVER

    Re: G force

    The ones that trick the Maf or IAT sensor increase the timing by tricking the car to think more air is entering the engine than there actually is making the the cars computer dump more fuel than needed while cruising around..
    Most cars the factory tune is already set rich to burn off pollutants hence the usual power & fuel mileage gains with a cold air kit or real tune that leans it out a little bit..
    I was taught to never use any of the chips and canned tunes other than an actual dyno tune with proper air/fuel ratio's being read and adjusted accordingly..

    Re: G force

    I think he has a late (2007 ???) DTS. I don't believe there's any such thing as a "chip" for these.

    BlueAngel#07, Please update your profile and login with your car, year, model, maybe mileage and approximate location. it sure makes diagnosis and advice easier.

    The $65 "chip" (which is really a 25 cent resistor in a cutesy box with connectors) offsets IAT to "fool" the PCM into dumping more fuel - richer mixture - into the air/fuel mix. As posted here and throughout CF, they don't work........... and the FWD setups are quite different from the RWD cars.

    For the FWD cars with a divorced MAF (clamped into the intake air duct) the connector is a 5-pin arrangement - 3 pins monitor the heated airflow monitor resistors and 2 pins monitor the IAT thermistor (the little black bead in the edge of the MAF bore)(Thermistor: a resistor which changes value as a function of temperature).

    CTSCHICK, Not sure about your 3.6 RWD car, but the "timing" in the FWD Northstar PCM controlled cars is pretty touchy - because of the new Northstar combustion chamber design there's not much advance available - they run about 34 degrees BTDC maximum and that drops back to 14 to 20 degrees BTDC under max power demands. No matter what octane fuels you use, these PCM's will not add extra advance to take advantage of the slower burn times offered by high octane fuels.

    I thought as much. G force says its actually designed for my car. ( which is a 2007 dts with 67000 on it. You brought up a good point about the dyno. Wondering where I can get it done now.

    Re: G force chip for 2007 DTS

    Please update your profile. Please.

    The "dyno tune" referred to involves running the car - on a dyno - while altering fuel and timing curves to achieve best power at various car/engine/transmission speeds. I don't believe that our FWD fixed PCM program cars have that sort of variable tuning luxury.

    I sure would like to be proven wrong, especially for a 2002.5 STS !

    (G Force used to market a "chip" for my car. It didn't work and it disappeared ..................)
    EDIT: Some of us have fooled around with inserting oddball resistors into the IAT circuit. That didn't work, either.

    Here's another money pit that doesn't work -

    I can't complain about the power curve the way it is. But I think I'm going to check .

    Do not install it...
    It is junk and as others have already said... it does not work...

    Call around to SPEED SHOPS in your area and find someone that uses either EFI LIVE or HP TUNERS software.
    Either one of those can be used to tune a 2006 or newer Northstar .

    I have had mine tuned... I absolutely love it.

    Hyper tech is the only plug and play tune that I would use and they don't offer one for the DTS so I'd have to suggest that the previous comment of getting a local speed shop or tuner to custom tune for you.
