    Polaris / HP Tuners: Injector Dynamics Calculator



    The good folks over at Injector Dynamics have just released a calculator to use when using their injectors in a Polaris. Using it is pretty straight forward. Good data in = Good data out.

    Feel free to ask any questions.

    Nothing to change with stoich as it doesn't care outside of lambda. You will use the scalar to adjust fueling for different ethanol contents. If VE is previously dialed in, you should attain near the same fuel trims and then you can tune from there.

    I didn't find anywhere to input PW Factor in.
