    Do you enter valid PIN code of your adapter, when choosing it in hobd?

    Hi cali!

    Good job your program. I have a chinese 7" gps, and elm based bluetooth obdII reader, in my e12 corolla, and almast ewerything is fine, but little lagging.

    I want one feature for this software (or two...)
    -Auto sleep the pna when the power off (like an igo8)
    -hotkey to switch to the navigation software.

    When you want implement this, i promis buy a full version.

    Hi.

    1) clarify please - who should go sleep at power off? Your GPS? Then you should setup this in system power settings (in control panel), not in hobd.
    2) there exist a "minimize" button which normally switches you to the another running soft (that could be a shell or nav window). You then may use your normal shell to switch to navigation window.

    Hi!

    Yes. when the power source(from cigar adapter) is off, when the car parking, the Igo navigation software send a message, about power down, and 10 second left the device is going to sleep. This function is must have for your software. (when i setted the power setting, in battery mode, not working...)

    In moving, is hard to switch between programs.

    Thank you for your replies!

    Probably you are right regarding the power option - will consider this.

    Regarding software switching - thats more complex. even if hobdrive allow you to switch to active navigation window, how will you switch back then?

    "how will you switch back then?" Yes it is a problem. But (i dont know how) The iGo8 and iGo Primo skin ability is the solution maybe. This skin allow to play videos from iGo with external media player aplication, ergo know start external aplication. i know is not your job, but it is a brainstorm...

    There is a request filled:

    http://hobdrive.userecho.com/feedbac...yuschego-okna/

    Small-screened mode, where hobd could be used together with other running software (navigation for example) and allow switching between them.


    Probably this solution can help eventually. It is however under consideration - not sure how and when it'll be implemented.

    Cail, nice application. I have a lot of fun using it.
    I have a question - why 'Fuel Economy Instant' shows infinity for almost all the time (when I drive of course). Fuel Economy Short also shows infinity for more than 50% of time, depending on 'UI performance' setting.
    I use the app with Opel Astra H with diesel engine 1.3CDTI, so my MPG setting is based on Engine Load.
    I can see that Fuel Economy shows infinity always when Engine load falls to 0. I think that Fuel Economy should also show 0 in this case (assuming that car is moving). Am I right?

    HI Kretek,

    Yes, depending on timing these two sensors sometimes give incorrect infinity value. This'll be fixed soon.

    What units are you using for display? If you use US (and MPG for Fuel Economy), then it is correct that you see "infinity" with EngineLoad = "0" - this means you will drive "infinity" miles per gallon. If you use metric units, then this seems to be bug - will checkout this.

    But again, FE Short and Instant are now abit incorrectly linked with the performance of your device&adapter - this'll be fixed.

    PS. BTW, How is your feeling on EngineLoad method of Fuel Consumption calculation? Is it precise enough with default settings? This method is experimental (since there is no other way to calculate fuel on diesels) and I'm interested in users' feedback.

    Hello Cail,
    I use metric units. I wrote MPG but I meant 'liters/100km' - my mistake.
    So, I'm waiting for next version with fixes

    Now, a few words about EngineLoad method. Works fine, I was surprised about it's accuracy with default settings. In my case it adds only 0,5 litre to the real consumption. It's better accuracy than with many proprietary onboard computers . I'll try to do some trimming when I'll find some time. It's quite possible that with 1.8 or 2.0 diesels it'll be working with defaults without any trimming
    I tried also MAF method, but with diesel it doesn't work good, but it's normal - AVR for diesel isn't constant, especially with chip-tuned ones

    PS. Do you have any idea how to do with trimming of RPM curve for Engine Load? I mean without access to professional laboratory equipment I thought about it, but don't have any solution ready yet.
