PWM Boost Control Solenoid Setup Instructions for eCtune and Hondata S300


Install the PWM Solenoid Components to your ECU in the Following Locations




Install the solenoid you purchased according to these diagrams.





Make sure you have a direct pressure source going to the SIDE PORT of your External Wastegate as well.


eCtune Software Setup


Setup your Solenoid Configuration like this screen.




Next move to the Electronic Boost Controller Settings Screen




Set your activation.  If you want it to always be active, set to Always on.  If you would like to be able to deactivate the Solenoid completely with a switch, use one of the available inputs.  You can also setup an activation input for Hi and Lo boost levels if wanted.


Activation Points:

-          EBC Activation is what you use to help increase spool response (faster spool).  Set this to just below your desired target boost level and set the Fast Spool Duty to something higher than your Fixed Duty Cycle (or what duty you will be running in Gear Based).

-          Wastegate Activation is the Spring (PSI) that you have in your Wastegate

-          Before going ANY  further, please make sure you Set an Appropriate BOOST CUT to guard against over boosting.

-          Set your Fixed Duty Cycle to an appropriate starting amount.  Begin conservatively and work to increase boost slowly.  Start at 10-20% and increase in 5-10% increments to increase boost.  Keep note of what % cause to you boost certain PSI levels…you can use these numbers later for Gear or RPM based boost settings.

-          Dial in your wanted boost percentages and then move to the Duty Lookup Map




Here you will take the particular Duty Cycle Percentages that you found while dialing in your boost and input them into a table.  The table reads from the largest amounts of boost on the left hand side and the smallest on the right hand side.  Double click the Target Boost (psi) column heading and type in the PSI of boost and underneath that the duty cycle % that achieved that amount of boost.  Do this for a variety of levels you would like to run until the table is completely filled out.


Next go into your Duty Compensation Maps




Here you will see two types of compensation, one for RPM and one for IAT.


As IATs increase or decrease, the solenoid will react differently…you can account for this with these settings.  Various solenoids will react differently in this table as some are more stable than others.


Some people like to increase boost as RPMs increase to artificially keep the torque curve as flat as possible.  You can use the RPM compensation table to do this.  You can also account for some drop-off in boost as RPMs climb but keeping the duty cycle up.  This will vary depending on your Turbocharger, manifold or Wastegate setup…


To setup Gear Based Target Boost…




Enter in the appropriate boost levels (PSI) that you would like to run in each gear for both your Low and High Boost setting.


For this to work properly, make sure you have the correct Transmission or Gearing setup in Hardware Settings àTransmission Settings




To set up RPM Based Target Maps…




Fill in the PSI you would like to run for each RPM listed for both High and Low boost settings.


That’s it!


Boost away and don’t blow anything up!




Hondata S300 Software Setup


Setup your solenoid configuration like this




Enable boost control (PWM) on output A11 should be checked


The solenoid configurations above are for a Normally Closed setup


Solenoid activation must be slightly below what your Wastegate spring is rated for


Start with a small Fixed Duty Cycle and gradually increase it to increase boost while noting what boost pressures are achieved at various Duty Cycle Percentages


Set your Pressure vs. Duty Cycle according to these boost pressures you saw as you increased duty cycle.  From there you can set Boost By Gear.


For the Air temperature compensation table, as IATs increase or decrease, the solenoid will react differently…you can account for this with these settings.  Various solenoids will react differently in this table as some are more stable than others.
