Your data logging from normal / spirited riding would tell you if fuel delivery is ok at heavy throttle (high MAP) and higher RPM. Be sure to log for IDC-F and IDC-R (injector duty cycle) as well as INJ-PWR F and R (injector power as measured in milliseconds).
Open csv log file in excel
Sort "Z-A" for MAP and expand sort to cover all columns.
Look across the rows for your highest MAP at highest RPM's - What does the largest percentage show for IDC and what does the largest millisecond reading show for INJ-PWR? For example, on my Breakout I can hit 5000 rpm at 100 map and my injector duty cycle F/R is over 93%!
This data will help tell you if your fuel delivery system is adequate for the motor under all conditions, or if it needs to be upgraded.

injectors at the bottom, throttle at the top, rpms in the middle.

Received my TT today, already had auto-tune pro so only needed the module. After reading the install instructions I have a questions for those that may of already installed, (I sent FUEL MOTO the same question but maybe someone here knows the answer). There was this note in the install instructions, “Note: The Target Tune module can be used in place of the Auto-tune module when using the Auto-tune Pro feature; but does require an additional CAN link cable that is sold separately (PN: 76950427) and calibration changes.” Now I believe the cable mentioned I already have because it’s the one that comes with AUTO TUNE PRO and I can see where it plugs into the TARGET TUNE module, but why is it needed and what does it do? ased on the information provided about TT on the HD forum there was no mention of needing an additional cable in order to conduct an auto tune and it appears that this cable is not included in a the full TT kit, so what gives?

Below provided by DynoDan:
Tune type > Process > Hardware required
Regular Tune > Autotune Basic > no extra hardware needed, uses stock o2's
Regular Tune > Autotune Pro > need Autotune wideband controller and sensors (CAN Cable)
Regular Tune > Autotune Pro > need Target Tune wideband controller and sensors (CAN Cable)
Target Tune Tune > Autotune Target Tune > need Target Tune wideband controller and sensors (CAN Cable not required)

Thanks J929626, that answers part of my question, but it would seem that with the can cable you have two options for conducting an auto-tune. What's the difference between a TARGET TUNE-TUNE (no can bus cable attached) and a TARGET TUNE using AUTO TUNE PRO (can bus cable attached)? There has to be a reason why the TARGET TUNE module even has the plug in for the can cable.

Jamie, thanks for the explanation. It appears to me that perhaps in the early planning/design stages there must of been a belief that a can cable would be needed. Is it safe to say I can go ahead and remove my can cable (previously installed routed for AT PRO) because based on your explanation it wouldn't make sense to not use the TT without a TT-enabled map or is there the possibility of some future actual benefit/application in the works?

Target Tune reads the wideband O2 sensors thru the ECM, it does not require a CAN cable. Hardware aside, Target Tune-Auto Tune and AT-Pro are two seperate applications on the Power Vision device that work very differently to populate tune corrections. If you have Target Tune installed and a TT enabled map TT-AT is the app you will use, you cannot actually use the AT-Pro app on a bike flashed with a Target Tune calibration. AT-Pro changes tables in the calibration differently and reads AFR over CAN. Technically you could use a Target Tune module as with AT-Pro as well, this would require a non TT-enabled map as well as a CAN cable.
But without the can cable you also loose the ability to monitor the lambda or AFR with the PV. I haven't tried a log as of yet, but I suspect something might be missing there also. But only in the monitoring.

With the Target Tune installed everything works just fine without the cable.
But without the can cable you also loose the ability to monitor the lambda or AFR with the PV. I haven't tried a log as of yet, but I suspect something might be missing there also. But only in the monitoring.

To monitor live AF with your Power Vision WBO2 AFR & Lambda front/rear are new Target Tune specific channels under vehicle signals on the channel list
Is there a software planned for converting the tune files for the TT ?
