    okay, yeah I still have one of opus older psu opus 150w which doesnt have the remote amp delay like the new 180w which I will be getting soon. Cause for some weird reason the 150 will restart during crank like after stopping for gas. which I hate cause I get two loud thumps. So do I need to by the relays you guys sell or can I get one from a local store?

    I am talking about the remote line on your amp itself, nothing to do with your PSU. It would work if you were using an inverter.

    And you can use any relay that is 12v and switches with less than 400mA. But then you will need to solder your own connector to the Fusion Brain.

    If you have one of ours, you plug it in and it works.

    No I was just say the thing about the psu cause it **** me off with the pop sound, thats one of the reason I was talking about getting a new one. I know I would be using the remote wire from the amp and not the power supply. lol I have those two pin wire I got from your website a year ago. So I;ll just use that wire to hook to the output of the FB.

    I need some advice,

    These are my readings in OHMS using 20k OHM setting on my MM.

    Idle 9.99
    CH+ 1.70
    CH- .78
    VOL+ .36
    VOL- .10
    MODE 3.74

    Since i am using Solution D, I was playing around with different resistors (using the 5v pin in FB) and got decent numbers using 220ohm resistor. Does that seem right to you guys?

    Also I have not been able to successfully manipulate the Vote Delay,, Any help please?

    Hardware:
    If you are getting a macimum of 9.99KOhms when idle, that is the value you need to use to determine the rest.

    Assuming your car puts out 14.4v volts when on (some are 13.8, some are 14.4, but again always design for the worst) and you want a maximum of 5v minus some happy factor to make it about 4.5 (if it spikes for somereason, and better safe that sorry) then you get:

    4.5 = 14.4 * (10k/(10k + Rmystery))

    Through some voodoo magic of algebra you get Rmystery to be 22KOhms.

    So that means you should get voltage out like this (at most, your car will be different depending on the voltage of it running):


    Software:
    I did redo the logic section recently, I may have goofed something. I will take a look at it.

    Update: The software was a bug. I had a hardcoded zero leftover from testing. Since I was in there I switched some things up to hopefully make it faster.

    It is loaded to the server, so just use the updater.

    why would i calculate resistor for 14 volts if i am not using 14 volts anywhere? i am using the 5v pin of the fusion brain to connect to the voltage divider..

    Ive never been good with algebra lol..

    Also - I updated MDX and am still not able to manipulate the vote delay. I have changed the number from 250 to 10000 and key presses are still being sent the same number of times.

    Any hints as to what i am suppose to do to get this to work?

    Thank you guys

    Ok, I didnt read that you were using Solution D. Sorry about that. Disregard it. But then substitute 5 for 14.4, and that will give you your value.

    As for the update, if you post 1 logic block (the part between the <if></if> tages) I can see how it is.
