    Actually you should be able to tell the difference between the two by measuring entropy on a fixed chunk of bitstream. If you send me an image, I can probably figure it out.

    You could (and probably should) run all the different airmass estimators at the same time. This way you can track if/when any calibration or parts are starting to diverge from each other. Also, it...

    512bit key for RSA is actually quite weak. Now if you're talking AES with 512bit key, then yea, we're proper screwed.
    Straight out of Wikipedia: "RSA claims that 1024-bit keys are likely to...

    I'd prefer to know how the torque estimation happens, or at least what variables are involved.

    neat!

    But for the long run we should probably have a more dynamic system, new injectors are coming out all the time, it'd be nice to have a 'i want X injector, but i have Y computer, what do i put...

    http://www.deatschwerks.com i've used these guys for a while, they'll flowtest your injectors at whatever pressure you want at no extra cost, so you have the most precise data for your IFR table.

    IDC, you can scan for it, but that most likely uses up bandwidth (I don't have the software in front of me, cant verify it), unless the default IDC PID is a calculation itself. If that's case please...

    RPM and IPW is all you need. the rest is math. no need to scan for it (read: waste your bandwidth), if you can just do a custom PID for it.

    1. MAP at idle will be higher, 228 cams tend to 'clean up' nicely after you start to raise idle rpm to 900rpm or above. 55-60kpa doesn't sound wrong, depends on many variables, idle rpm, how warm...

    I've done that, you can calculate the entire VE table from MAF, or vice versa. It's very simple, you can just do it with histograms. You set up a MAF calibration-like table, except for the airflow...

    you run out of MAF, you switch to SD. Then you run out of IFR. Even if you do a good job on that, then you still can run out of RPM. at one moment you actually need to abandon ship and graduate to...

    congratulations, you've discovered that in a airmass formula of GMVE*MAP/TEMP, if GMVE and TEMP don't change, MAP is the dominant factor in airmass (thus airflow, thus fuel consumption). go algebra!...

    different PIDs are going to use different smoothing of component PIDs, so expect slight discrepancies, especially on transients.
