Power Vision PV Log Tuner Basic/Pro Instructions and tuning tips
1.
Check for Firmware update connect your Power Vision unit to
your computer, open the update client and make sure you have the
latest firmware. PV Log tuner requires firmware version 1.0.3-723 or
later. Also make sure you have the latest PV Log Tuner software
2.
Create a Value File. Open your calibration in the WinPV software
and create a Power Vision value file under File/Save Selected Values
that has the following tables: VE front, VE rear, AFR or Lambda
fuel table, and Front and Rear Spark tables. You will need to switch
the software user level to Pro by going to Setup/Options/User
Level in WinPv
3.
Mount the Power Vision on your bike, go to Datalog/Assign
Signals and configure your Power Vision to datalog the following
channels:
MAP
(Manifold Absolute Pressure)
TP (Throttle Position)
Engine Temp
Engine Speed (RPM)
Accel Enrichment
Desired/Set AFR (if you have an AFR based fuel table) OR
Desired/Set Lambda (if you have a Lambda based fuel table)
Warmup AFR (for AFR calibrations) OR
Warmup Lambda (for Lambda calibrations)
Front Spark Knock Retard
Rear Spark Knock Retard
VE New Front
VE New Rear
Note:
Log only these specific channels
If you
are using the Auto Tune Module/Auto Tune Pro you will also log:
Lambda 1 (Dynojet Channel)
Lambda 2 (Dynojet Channel)
**OPTIONAL LOG TUNING METHOD**
As an alternative to logging the channels noted above you can also
use the following procedure on your Power Vision unit. Go to
Settings/Enter Code and enter the PIN number 319245 which will bring
up a mini tuning screen which will not only allow you to monitor
your hits in real time with a tracer cell, it also automatically
logs the correct channels required for your calibration. You can
start and stop logs right from this screen as well.
4.
Datalog with the Power Vision. Start the bike go to Datalog/Gauges
and press “start log”. Ride the bike as normal, trying to vary the
load and RPM as much as possible. It may be helpful to use the PV to
display helpful channels for visual reference such as MAP, Engine
temp, Throttle position, and Knock retard, make sure to press “end
log” before you shut the motor off
5.
Retrieve Logs that were created from the Power Vision. Connect
the unit to the USB, open the WinPV software, go to “Get Log” and
retrieve your log(s) and save them to your computer
6.
Configure PV Log Tuner Software. Open PV Log Tuner software and
go to “Options” and set the following parameters:
Stoich
Value 14.6
Minimum
Hit Count 50
Minimum
Engine Temp 185
Maximum
Engine Temp 288
For
Auto Tune Basic check
the box “HD OEM O2 sensors for correction”
For Auto Tune Pro with the AT Module check the box "Use Auto Tune
for correction"
Note
1: If you have a 2011-2012 Softail or 2012
Dyna model you must turn on HD-CAN
enabled tuning by hitting the Contol-E keys in the log tuner
software
Note 2: If you have your original factory O2 sensors installed as well
as the Auto Tune sensors at the same time you can check the boxes
for both the OEM sensors and Auto Tune and Log Tuner will use data
from the factory sensors during normal closed loop operation and
data from the AT sensors in the open loop areas of your calibration.
This works very well
7.
Import Value File go to “Open PVV” and load the value file that
was created in Step 1
8.
Import Logs go to “Open Logs” and load the log files that were
created in Step 4. You can load a single or multiple logs
9.
Calculate Tune click “Calc Tune” which will calculate
corrected VE values and Spark Tables for the conditions and events
that were datalogged. You can click on the tree view to see each
calculated table
10.
Apply Tune click “Apply Tune” which will apply the new
calculated VE/Spark values to the original Power Vision value file
that was loaded in Step 7
11.
Save PVV click “Apply PVV” which will create a new Value File
with your corrected tables, you will name this file and save it to
your computer
12.
Import Value File Using WinPV open your original calibration and
import the value file created from Step 11. Make sure your use the
same calibration that was used while datalogging in step 4. To
import the Value File open your Power Vision calibration, go to
File/Load All Values and select the PVV that you created and saved
in step 11.
13. Reflash ECM now that you have an updated calibration,
save this calibration with WinPv, send it to your Tune manager and
flash your ECM. Make sure that when you flash your updated
calibration that you reset the fuel trims
Tips/Advanced options
Keep
log sessions to 15-30 minute session, this keeps the logs a
reasonable size and is generally ideal for collecting and sorting
data
You
must have a closed loop calibration to use Log Tuner Basic. To
enable closed loop, Lambda values must be between .98 and 1.02 for
Lambda based calibrations, AFR based calibrations
must be set to 14.6
PV Log
Tuner uses only certain data and also has specific filters, however
for the quickest results it is recommended that you disable
Accelerator Enrichment, Decel Enleanment, and PE Fuel during the log
tuning process. To disable AE and DE you can go right to the AE/DE
Multipliers and change them to 0, and for PE set the PE Enable RPM
above 6200
Log
Tuner Basic will populate approx 2/3 of the normal operating range
of the VE tables using the standard Lambda/AFR table in most Fuel
Moto closed loop calibrations, and in most cases higher RPM/Load
areas should be well within reasonable tune for a given combinaion.
However more advanced users may choose to increase the area that PV
Log Tuner Basic will populate by enlarging the closed loop area of
the AFR/Lambda table. This is done by extending the Lambda/AFR
values up to approx 4000 RPM and 80Kpa. I recommend first doing some
PV Log Tuner corrections with our standard AFR/Lambda table and then
if necessary extending the tables which will allow you to gather
additional data. Note if you extend the closed loop area it is also
critical to monitor engine temp and spark knock if you are setting
up the table for closed loop operation in higher load areas. As a
general guideline I would also recommend removing approx 4 degrees
of spark timing as well. Also note if you are extending the closed
loop range that when you are done logging and create your tune that
you return your AFR/Lambda table to the original desired settings to
ensure a proper mixture.
When using
Log Tuner Pro with the Auto Tune we find it generally works best if
you set the Fuel table to a single value when tuning, this works
especially well for visual reference when tuning. We generally set
this to 13.0 AFR/.89 Lambda, when your tune is developed you can set
the Fuel Table to your preference
