PHP PERFORMANCE UPGRADES
- Resolves many cold-start issues
- Usually results in more MPG
- Improves tip-in throttle response
- Results in better overall drivability from idle up through 3500 rpm
- Proven performance gains up to 100 HP
- Eliminates annoying injector post buzz
- Works with most ECM tuning
ECONOMY – Improved throttle response and economy without any significant power gains. Good for all applications, but generally used when the ECM has a high horsepower tune and additional fueling is not desired. This pairs incredibly well with our custom tuning for a nice mix of the benefits of ficm tuning while still retaining the benefits of custom ecm tuning. This tune will give you the mileage and start up benefits while our custom tuning gives you the power, mileage and trans shifting you are after.
ATLAS 40HP – Improved throttle response and economy with a 40 HP gain. Useful for mild to heavy towing or when excessive exhaust gas temps (EGTs) are a concern. Good for trucks without head studs. This is the biggest FICM Tune we suggest with our custom tuning. Anything bigger will create excessive smoke and we will not be able to control your injector pulse width properly.
ATLAS 80HP – Improved throttle response and economy with an 80 HP gain. Best for daily driving or very light towing.
HERCULES 100HP – Maximum performance with a 100+ HP gain. Not recommended for towing as it can increase EGTs. It’s recommended you run an EGT probe to monitor temps. NOT RECOMMENDED FOR TRUCKS WITHOUT HEAD STUDS.
HOW TO CHECK VOLTAGE OUTPUT ON A 48V/58V FICM
To check the actual output voltage on a Grizzly 58V FICM, you must use a voltmeter. We implement a modification process that tells the PCM that 58 volts is actually 48 volts because the PCM would otherwise report an error code at 53 volts. In other words, with our modification the PCM sees 48 volts, the injectors see 58 volts. And since the scan tool communicates with the PCM to check voltage, you will only see 48 volts with a scan tool.
Remove the access cover on the back by removing the two T-20 screws
Carefully remove the access cover by gently prying the cover off of the module.
With access cover opening oriented to the left side, place the black lead on the top screw and the red lead on the bottom screw. Be very careful not to short the red lead to the module case. This could damage the FICM.
