Is the installation of the controller plug-and-play?

Yes.  Each controller is provided with all the necessary electrical connectivity accessories.  There is no wiring modifications required on your vehicles.  No wire cutting.  No wire splicing.  And, if ever decide to remove the controller, the car is exactly as it was before you installed the controller.

How does the controller obtain its power?

With the Model B series and the Model E3  ...  The controller gets power from the vacuum solenoid connector.  The car’s connector provides the power through one of the two pins on the cable.  The Forza connector connects to that cable, routes the circuit through the controller module tapping into the positive side while doing so.  The circuit is then passed back to the vacuum solenoid valve through the Forza connector, which completes the original circuit on the car.  Only, now the controller is between the car’s ECU and the solenoid valves.  When the controller is set for normal mode, the circuit is as if the controller were not installed at all.  When the controller is set for open mode, it interrupts the current going to the solenoid while simultaneously presenting to the ECU a complete circuit which simulates the solenoid connection ... so the ECU does not sense an open circuit and record a fault.

With the Model E1 and E2 ... power if provided differently.  These models obtain power from a fused circuit on the car.  A fuse tap is provided with the kit to make this connection.  The controller then acts as a smart switch in-line with the exhaust bypass valves. 

In all cases, all electrical connections are provided in the controller kit.  And, as stated above, there are no wiring modifications on your vehicle.  Everything is plug-and-play

How difficult is it to install?  Is this a DIY project?

On some vehicles the installation is simple.  If you are handy with a wrench and screwdriver, it should not be difficult.

A lift or means of raising the vehicle up is useful in some instances.  E.g., the Alfa Romeo Giulia is an easy install, but you will need to gain access under the rear of car.

In the most extreme examples, the rear bumper may need to be removed.  This is generally not difficult, but for the novice can be a daunting task.

Many customers elect to have a shop perform the install.  Any competent auto shop should be up to the task.  Also, reputable car audio system installation shops can be a good source.

Will using the controller cause a Check Engine Light or log a trouble code in the car's ECU?

It should not.  We make every effort to ensure that the controller is fully compatible with the vehicle.  If a trouble code is known to be caused, we remove that vehicle from our compatibility list until a fix is implemented.

Will the controller void the new car warranty?

In the US, there is a Federal statute know as the Magnuson Moss Warranty Act enacted in 1975.  In accordance with that act, a manufacturer cannot void a warranty because the consumer installs an aftermarket part unless they can demonstrate that the installation of that part caused damage to another part that is covered under warranty.

Using the Forza controller should not have any negative effect on any other component on the car.  That said, if you have doubts, remove the controller prior to submitting the car for warranty repair.  Once the controller is removed, there will be no evidence that it was ever installed.

What is the return and warranty policy for the exhaust controller?

You can return the controller for a full refund of your purchase price within 15 days of receipt.  Contact us prior to return.

All controllers are warranted for 12 months.  Should the controller fail, contact us for replacement or repair.

Is there a battery drain when you install the controller?

The only potential for battery drain is on the Camaro Generation 5 (model years 2010 to 2015).  The Camaro requires a power tap installed in the rear fuse panel.  This fuse panel, on the 2010 to 2015 Camaro is always active.  I.e., when you shut off the ignition, the fuse panel is still energized.  There is, however, a solution described in the installation instructions ... and ... the controller for the Camaro has an On/Off switch so you can isolate it from the electrical system.

For all other vehicles, there is no battery drain.

Can I program the remote to the car's HomeLink system?

Yes ... if the car's HomeLink system is 2014 or later.  Refer to your car's owner manual for instructions on programming the HomeLink.  Click here for generic HomeLink programming instructions.

What are the options and alternatives to using the remote fob?

You can program the remote fob to your car's HomeLink system if the HomeLink system is 2014 or later.

You can also use a manual switch in place of the remote.  Instructions for configuring a manual switch for the controller are included in the installation document(s).

Can the controller be used on different vehicles or is it set to use on only one car?

Depending on the controller model, you may be able to use it on a different vehicle besides the one you first installed it on.  Check the Compatibility Matrix and the installation instructions that came with your controller.  You can access the installation instructions here.  If you have any questions, please contact us.

Can the controller by programmed to open the valves when first starting the vehicle?

Yes.  If using the remote, you can configure the Model B4 or Model B4A with your choice of either valves open at vehicle start or valves in normal mode (ECU control) at vehicle start.  The Model E Series of controllers do not have this capability. 

If you are using a manual switch, the position that the switch is in will dictate the controller mode.  Because a manual switch, being a mechanical device, the position of the switch is not lost when you turn off the ignition.  Upon restarting the car, the controller will assume the mode that the switch is set for.
