    WoW...while you are fu cking around with all this crap...I'm out riding my bike with a good old PC5....Tuned to 140/140

    Does the Maximus have the capabilities to holding 2 separate maps?

    Does the Maximus have the ability to add a power shifter?

    Does the Maximus have Launch control?

    PC5 does...just saying

    Still wacking away on my Maximus tuning, but I'd have to say that the Maximus is simply a portal and logging tool. It grants access to the ECU, and reflashes the ECU tables. The real work is done on the PC, in DirectLink. There, you can have as many maps as you want, and interchange tables using spreadsheet tools.

    No power shifter. You *can* set RPM limits for Neutral and all 6 gears. I have my Neutral RPM limit set to 4,000 rpms. I believe that with the clutch held in, not rolling, the ECU isn't detecting any gear position, and will apply the Neutral RPM limit...

    I have to really keep my wits around me with this Maximus. Not for the faint-of-heart. More than once I've forgotten a step or something, and had to redo a reflash. The datalogging is also intense, wanting to hit every tuning cell is quite difficult, and thrilling. Imagine blasting up to 120 mph in 4th, numerous times. Not too much of a problem out here in the Hill Country boondocks, with some hills to load it down. Logging in a metro area? Good luck.

    On one of my logging runs, I wanted to hit the low-rpm (1,000 - 1,800), high manifold pressure (MP) cells. Doing 30% throttle in 4th gear, starting at 20 mph, the bike started to do the "hucka-bucka". When it got up to 45 mph, suddenly a loud *clunk* and *screel*. Rear wheel locked-up, and I'm white-knuckling a frozen, fishtailing bike down the highway. Managed to get it stopped, upright, then into neutral and rolled it onto the shoulder. Yup, total engine seizure. Sat there and burned a couple, let it cool off for about 1/2 hour. Put it in 2nd, rocked it fore/aft, and the engine unstuck. Let it cool some more, and try a startup. *Whew*, it started up fine, no rattles, no smoking. Thank god for modern cylinder coatings. It's been running fine since.

    So, those dag-nab goofy ignition tables got a complete overhaul. Now, no more "hucka-bucka", and it behaves quite nicely while cruising at 1,200-1,500 rpm. Very well mannered down there now, like my ol' panhead.

    My "hair-on-fire" drag racing days are long over, and this sedate old man mostly just wants a pleasant cruise around our Hill Country backroads.

    But still carry the "big stick"...

    I believe the PVCX can store at least a couple different maps, so a roadside change can be done standalone.

    Same here. My speedo is 4% off, wanted to adjust that. No provision in Maximus.

    However, doing the "gauge" display while riding, DirectLink shows correct speed, compared to my GPS.

    So, the inaccuracy is in the instrument, *not* in the ECU.

    Since the speedo signal comes off the mainshaft, the ECU will get the gearing right, irregardless of final ratio.

    Just need to crack open the speedo, see whut's in there...

    You obviously didn't understand my statement.

    PV5 has the ability to hold 2 separate maps on the bike and can be switched back and forth on the fly...

    The PC5 has a "power shift " input...hold the bike wide open, kick the shifter, it interrupts the ignition/fuel for a predetermined amount and "power shifts" without using the clutch...

    Now these fetures are not for everyone...just the ones that need it...LOL

    I have PC5 and Maximus on the magnum. For just a cam tune (501 or 505) I will give the better tune to Maximus. smoother throttle response and clean pull to redline.
    I wouldn’t mess with an on the road tuning device when a one time Dyno tune with today’s Maximus is just spot on.
    After all we are talking about stock bike tuning here right ? stock heads and valves. Stock Throttle body ?

    @waterhog, may I ask if what kind of display indication the CX provides, if any, to help one hit certain load-RPM points during datalogging?
