    LC-1 Wideband not working in HP tuners 2.X

    After installing the new 2.x version of HP tuners on my vista laptop, i cant seem to get the LC-1 to read properly, it constantly reads 21.4 what is going on?

    It may have reset how you have the voltage settings set up...the custom inputs? eg. Like 0v = 10 a/f and 5v =18 a/f or are you using the ones already input into hp tuners?

    Did you try reprogramming the LC1 to see if the a/f value it was showing changed. Here's a good thread on how to check for voltage offsets.

    I believe it show's how to read raw voltage. Not sure on that though. Try changing a few things to see if it makes a difference. Do you have a gauge hooked up to your lc1?

    I will give that a try. I do see they have a new firmware available on their site since my purchase and install.
    The LC-1 is hooked up withthe brown wire to my HP Pro device. It worked in the fall last year perfectly.
    New Laptop Vista and the new Hp Tuners it stopped. working.
    When the car was in storage over the winter the battery was disconnected. Do you think that erased the programming of the LC-1?

    could have, the LC1 is junk. I would bet it is something with that and not HPT as everyone would have seen that issue on here if it was HPT related.

    Have you loaded LogWorks? You should do that so you can verify that the problem is or isn't with the LC-1 controller/sensor and flash the controller with a fresh config.

    I just have never had (nor heard of) anyone having good luck over a period of time with the LC1.

    Check for your VCM Suite config files in C:\Program Files\HP Tuners\VCM Suite 2
    License.dat
    VCM Editor.cfg
    VCM Scanner.cfg
    VCM Suite.cfg

    And move them to: My Documents: then HP Tuners\Settings
