    ECM and stuff (sorta) explained.....

    i'm going to try the CAN when i get home. when i use PV on the dyno, i have it plugged in to the bike, and to the computer, but i use the dyno to collect the data so i can have it all synced to the torque data. i massage the output with some scripts i wrote so other tools can read it. i'm...

    power core tells you the control center is running and will shut it down for you so it can connect to the pcv. running control center after that doesn't mess up PowerCore that i can see, but control center can't see the pcv until PowerCore is shut down.

    doh! well, i stand corrected. i went out and grabbed a PCV that came in a box of other stuff i had bought and tried plugging it in again. (the last PC III i looked at was pretty old i was removing it for a PV, i guess i didn't note any ignition settings in it). this PCV i thought was broken...

    dunno. i tried calculating the theoretical numbers for those combos and they all came in some a bit lower. a 120 at 11.8:1 with an Andrews 64 or a Woods 75 should be around 200psi. my gauge is a matco. i had another gauge that was coming in way low initially (was only reading about 180 or...

    they've had fuel, but they dont have (at least i've never seen) one that can advance timing.

    send me a link to your calculator. i get around 207 on the calculator i use www.bigboyzcycles.com so i'm right around perfect. (gauge pressure). i've blueprinted, so i know exactly what my bore, stroke, rod length, chamber volume, dome volume, gasket thickness, deck clearance, etc is.

    oh, and before i forget, does the ignition module also read temp and have a table to adjust for temperatures too? that's pretty common, having a main spark table but also a secondary table to pull timing at some higher IATs or something.

    ECM and stuff (sorta) explained.....

    well that's what i'm wondering. maybe what they do is just simply sample the ignition timing from the ECM and then as they get the pulses as the engine is running they fill out the stock mapping as different points are hit. only then are they able to advance the timing. they can't make it...

    so early intake close. where could i find the info on the cam specs? still question whether DJ PCV can only retard timing or is there some method to advance timing from what's in the ECM. in order to do that, it would need to know a bunch of things i think. retarding timing is easy...

    can the PCV ignition module advance the timing?

    ECM and stuff (sorta) explained.....

    does it? or is the MAP just the X in the RPMs Y in the table at the time the injector pulses? meaning, at the time the injector pulses at low RPM, is the intake valve still closed, or is it open or do we even know when in the stroke the ECU reads MAP for a given cylinder? does PCV for the R3...

    ah! well 8.7:1 is pretty low, and yes probably fairly safe to play with a bit. (i'm used to higher CRs where it can get a little bit more touchy, the engine in my bike is 11.05:1). so yeah, 8.7 you've probably got a bit of room. hopefully you've got a a dragstrip and/or are keeping track...

    timing.... doing anything with timing other than removing it because you've got knock sensing capability (even then it's kinda dicey) *without* a dyno (and someone who actually knows how to use it) is Bad Idea(tm). most people with just basic mods like intake/exhaust, etc. should just forget...

    ECM and stuff (sorta) explained.....

    Yup, i get what you're doing. i suppose my question (without knowing a ton about how the R-3 ECU algorithms) would be, how do you know when to sample the MAP? MAP is changing constantly as the valves are opening and closing and the ECU is sampling it at a certain crank tooth for a particular...

    (tried replying to other thread, but 10K character limit.....) a little reading and i answered my own question about 3 vs 1 MAP sensor. 1 sensor connected to all 3. interesting. i also read a little bit about how people are using the MAP sensor input to a PC-V (or whatever) to try and make...

    New guy, dyno tuner.

    it's about 1000lbs. i don't remember the exact mass, but that's stored in the dyno hardware stack. the eddy current brake is about 750lbs.

    DYNO TUNER QUESTION

    do any of the flash tuners for Triumph have the concept of 'tune license'? basically, (at least with some flash tuners for Harleys) you have the hardware to program the ECU, which is locked to the VIN of the bike. if you have multiple bikes (or are a dyno operator!) you purchase tune licenses...
