Datalogit FC-Edit software

Install the Full installer first and then copy and paste the 2.127 over the existing FCedit.exe.  Im not hosting viruses, but scan anything you download first.

LM1 WBO2 and Dataloggit

Here is a PDF on how to use the Innovate LM-1 Wideband O2 sensor and the Dataloggit for PowerFC tuning.

PIM to PSI Conversion

Power FC tuning IS overwhelming. It’s as user friendly as it can be, but engine tuning is not a user friendly process. Here is one of the many calcuations and coversions you will come across.

This pertains to the PIM values that PowerFC ominously hides your Boost Pressure as. They actually correlate to PSI.

Its VERY important to remember that 0 PSI in many cases is VACUUM not outside air pressure. We live on earth and there is 14.5 PSI of pressure at sea level ground. Damn gravity screwing up our calculations

PSI=(PIM*0.001422)-14.7 approx

 

Power FC Boost Controller Kit

The Power FC has an optional boost controller kit that allows the PowerFC to manage the wastegate and ultimately the boost level.

This kit comes with:

a 3 bar boost sensor that is plug and play

a wastegate solenoid

 

To install:

Remove the hose and wire from the stock MAP (Manifold Air Pressure) sensor.  Plug both into the new 3 Bar MAP sensor.  This is plug and play.

The old sensor can be used with the supplied 3 or 5 pin wire.  It is supposed to sense elevation changes and be a redundant boost sensor up to 15 PSI. Not necessary.  This wire will plug into the side of the PowerFC main box next to the commander plug.

The wastegate solenoid plugs right into the stock wastegate plug.  If you have modified your car and eliminated the wastegate wire, you hopefully have spare wire pins to rewire it back into the PowerFC.

Turn the key but dont start your car.  You must make some changes to the PowerFC for the wastegate solenoid.  The boost levels will have two numbers (for the stock twin turbo system) you will only look at the primary setting.

Go to the ETC menu and go to functions. Disable sequential turbo function.

Go to MAP (may be called PIM) sensor menu and choose option 1 instead of normal. If you don’t do this, the car will not want to start and will be very unwilling to run.

PowerFC Excel Spreadsheet Tuning

Here is an Excel (XLS) spreadsheet for tuning the PowerFC once you have captured AFR values.

Use with caution.  Ill detail this page more as I begin tuning again.
