    If I were a Sub guy, I would first borrow a laptop and then take a hard look at either:

    www.ecutek.com

    Or

    www.tactrix.com

    Both have interfaces and software with intimate knowledge of Sub vehicles. If you wanted to experiment first on a budget, the Tactrix "OpenPort" interface, combined with the free Tactrix software, will give you a lot of insight into what's available from your car.

    That particular interface is also something called J2534 PassThru compatible, so it should work with software like DashCommand from Palmer Performance (a popular OBD-II dash display application people use here).

    This will get you learning a lot more about your car and seeing what kind of data is available to you.

    On the cool display and underlying computer, you could just try going to the store here. There appears to be a good selection of touch screens and suitable automotive PCs.

    Find a combo (and there may be complete turnkey systems as well), that appeals to you and which will install fairly easily in your ride.

    Last, connect what you are running on a laptop in step one above to the system you involved in step two below.

    I know it can be appealing to just want to buy and plug, but in the long run I think you will be happier going through some learning curve. It takes more effort, but you'll end up with exactly what you want.

    Good Luck

    Here are some more links for data logging and display software that uses the SSM (Subaru Select Monitor) protocol. You need a Tactrix cable or another one that supports SSM.

    RomRaider has a dashboard view but is best for reflashing your ecu.

    SawMill is a simple digital dashboard of selectable ecu parameters. Here is a screenshot.

    Dashcommand/ OBD/ scantool / CarPC combo could be a solution if you can read all the PID you need but you will be not out of the wood.

    This combination got two major hick up, the odometer, who in some car the value are retained in the BCM, and the other major problem is when you shut off the car and/or the CarPC will go on standby the data link will be interrupted and the connection will lost , it will not automatically come back.

    SO every time you will need to re-boot the PC and re-launch the soft., I have this set up, I have two LCDs as my main instrument gauges, and that the problems I'm facing.
    I wish I was aware of this before spending all this money ...and time.

    Actually if the PC could be put on stand by and wake up when you turn your car on, it will be the simpliest one, the first to discover is if you can have all the PID you need from the OBD, if you can or do not have an ODB, you still can do it , but then it start to be complicated because you have to take each signal, pressure , levet, temp and threat the signal to make the pc "use it" The dashcommand and the OBD is almost a plug and play.

    I check for Magden, they are going toward building software instead of full system.

    You still have Fusion Brain,but It seems more complicated

    I read that they have some solution all ready made for Sub.

    The best way to find your PID is to download the ScanXL from Palmer Performance get a scantool ODB reader, be sure to check if it will work with your car and read the data.

    To be honest I'm not that familiar with the Sub, make some research before buying anything.
    I have a Chevy Cavalier 05 and it use the J1850 protocol, google is a good help as well
