Forza Dual Mode Exhaust Controller

Hi Camaro5 ...

We are a new sponsor here at Camaro5 and have just announced the Dual Mode Exhaust Controller for Camaro's and Corvette's with the Dual Mode Exhaust (NPP) option.

With this controller, you take back control of the dual mode exhaust on your Camaro. You can select to have the exhaust bypass valves open all the time or closed to quite things down. Your choice.



The Forza Dual Mode Exhaust Controller is an evolution of a controller that was originally developed for exotic sports cars such as Ferrari and Lamborghini. After a few months of development, the Forza Controllerfor Camaro and Corvette is ready.

This is not a copy-cat product. It was completely designed as an evolution of another exhaust controller that we have been manufacturing for over a year. From the onset, we designed this new product with both quality and function in mind. We are proud to say that we have achieved that goal. No other controller device on the market matches the quality or the overall functionality of the Forza Controller. Check for yourself. From the wiring connections to the electronic enclosure … no other exhaust controller compares.

I have posted all the details in the Sponsor section and invite you take look.

http://www.camaro5.com/forums/showthread.php?t=398390

I think you will agree that the Forza Controller is the best exhaust controller available.

If you have any question, feel free to post them.

Thanks

Steve

Welcome..

Just so I'm clear. When this is in closed position the car is basically back to stock configuration where it will open and close.

Hello mlee,

You are correct. When in the "closed" position, full control of the exhaust bypass valves return to the car. In this mode, the car's ECU manages the opening and closing ... just as it does without the controller.

When you press the button to open the valves, they are open all the time.

Regards,

Steve

Hi mlee,

I certainly try for that. In my experience, it is very frustrating to go to install something and your missing some part or some details on instruction. With my other controller and this one, I spent many hours writing up and testing the installation instructions. And, I am including accessories to help out as well.

Regards,

Steve

The Forza controller is excellent

The Forza dual mod exhaust controller is excellent. The price is a steal at $78.50 which includes free shipping. I have this very model installed on my ZL1. The kit includes every thing you need to do the installation.

Two things I really like about the controller. One, the controller can be configured to use either the wireless remote (included) OR you can hard-wire it so it can be activated by a switch that you could install in the cabin somewhere (cabin switch not included). Two, the controller has a lighted push-button (LED) on/off switch that allows you to switch off the unit if the car is not going to be driven for an extended time. The current draw of the unit is minimal, but best to shut off the unit if not driving the car for 2-3 months.

Installing the unit was easy, but I did have to notch the existing plastic fuse box cover to make room for the fuse-tap wires. And I did use a zip tie to get the fuse box cover to stay on - the fuse-taps are just tall enough to keep the fuse box cover latches from engaging fully.

I don't know for certain, but i don't think it would void the warranty of the exhaust bypass valve itself. What the Forza controller does is intercept the power going to Camaro's exhaust bypass valve relay - so basically it just reroutes the power. The Forza controller is fully fused so as not to cause a short-circuit. Also, the controller will only work if you have a Camaro with the Dual Mode Exhaust option (NPP).

Thanks, Perry, for the review. I appreciate it very much.

I do not think there should be any issue with the warranty. The controller is in effect opening and closing the circuit to the vacuum solenoid valve. This is akin to pulling the fuse. There are Chevrolet dealers here and there that are actually providing dual mode exhaust controllers. So, they obviously recognize that the action of opening and closing the circuit to the vacuum solenoid valve is not a problem.

What many people have done is merely pull that fuse out and leave it out. Obviously a very inexpensive solution ... but, once it is out, it is not a quick matter to put it back in.

Regards,

Steve

Anyway to make this a 3 way controller?

This way you could have open, closed, or off (let the car control it).

Tony, you're suggestion is close to how the controller works. With the unit switched on (receiver is listening for the remote) there are two modes you can choose. First mode allows the car's ECM unit to control the exhaust valve just as it did from the factory. Second mode is always open. I suppose Forza could make a model that would keep the exhaust valve always closed (silent mode).

Good question. I wondered about this also. Fortunately Forza has a page that does a complete comparison between their controller and Mild2Wild. Here is the link to the comparison. Go to tabs at bottom of linked page. There you'll find the comparison.

This can easily be done with a three way switch, and just inserting one side of the switch in line with a single wire.

On the Forza controller for Ferrari and other exotics, the device will function in the way you mention. That is, Always Open, ECU Control and Always Closed. Click here for some details.

When I was developing the controller for Camaro / Corvette, I thought about doing that but in the end decided against it for the first version as it increases the cost and I thought there would not be that much interest in having it.

Technically, it requires a two-channel RF transmitter / receiver not just a single channel. And you would need another relay on the circuit board for the circuitry. That would take the total number of relays from two to four and increase the size of the printed circuit board, which would mean a larger enclosure. All of that would add cost.

As one person said, you can do this with a mechanical three way switch. Sounds easy, but for a commercial product, that would be high risk as the wire would be carrying +12V and if you frayed the wire and it shorted out, you could be looking at big repair bills. Also, on the diagram that you linked to, requires modifying the electrical system with cut and splice. A no-no for me as any product that I put out has to be plug and play and completely reversible. Cutting and splicing, etc, is not something I would recommend some one undertake unless they really know what they are doing. The person who put out that diagram did not follow good practice at all. He should have employed relays to handle the electrical load and then the wires could have been merely ground wires for the relay coils. Much safer method. His method has too much risk and should be avoided.

On the Forza controller, the wire for the manual switch option is only a grounding wire. All that wire is doing is providing a ground to a relay coil. If you short that wire out, no sparks and no damages. Any commercial design for a three way would have to be a pair of grounding wires that would merely close the coil side of remote relays back at the controller ... like is done on the Forza unit.

Another thing with Always Closed ... with the Ferrari and Lambos, when the valves are open, the cars are much louder than Camaro's with open valves. So there was bigger demand for an Always Closed option.

On the next version ... I might go ahead and incorporate that option if there seems to be enough demand to warrant it.

This is better ...

No wire cutting or splicing. The wires to the 3-way switch are ground wires only. No danger of sparks and blitzkrieg. Yellow wire tap into any hot fuse ... RDO is good one. The Purple / White wire tap into Exhaust Flapper fuse position. Purple is hot side. Two relays. R1 is the always open relay. R2 is the always closed relay. When both relays are at default position (3 way switch in center position), the exhaust bypass valve is under ECU control.

Important ... completely reversible. Take all this stuff off and car is completely stock again.

Edited March 6th by Steve ... I reviewed the factory circuit diagram again and my thought about an Always Closed Option is not likely going to work. The original 3-way is not going to work. It will not hurt anything ... just will not work. I removed the 3-way diagram. The diagram now shown does not include the Always Closed. It is only a diagram showing how you can insert a manual switch for Always Open and ECU control. I apologize for any confusion if some one has attempted to use my original diagram. ... Steve

By the way, the circuit diagram I posted is in essence the same manual switch circuit in the Forza controller. Except the Forza Controller does not have the Always Closed option. Maybe later.

If all you want to do is add a manual switch and you are not concerned about the Always Closed part ... just remove relay R2. Relay R1 will perform the task of ECU Control and Always Open. The parts you would want to get for this is the automotive relay with a flyback diode to protect against reverse RMF, two fuse taps, some 16 or 18 gauge wire and some terminal connectors. Cost of supplies should be on the order of $10 to $20. Add in the miscellaneous wires that you may not have lying around for another $5 to $10. Then add in your time.

By the way, most cheap automotive relays do not have a flyback diode protection across the coil side. It is good practice to avoid those. On car with DC current, flyback diode protection across the coils side of relays (or at least a bleed down resistor) are almost always used to protect sensitive circuits from voltage spikes caused by switching relays. Your common auto parts stores like Auto Zone probably do not sell those. Those are OK for horns and lights. Avoid those types of relays when you are getting in close proximity to the any of the vehicle's computer bits and pieces. You need to get the better relays an electronic parts supply store.

You do not need to, but it would tidy things up if you got a small electronic enclosure and terminal block to put the relay(s) inside and your various connectors. That would add another $10 to $20 or so.

Or ... you could get the Forza Controller for a small amount more, have the manual switch option if you wanted it ... PLUS have the wireless remote control option ... and you would be done.

I'd be willing to pony up a bit more to get the full-open/car controlled/full-closed version if you came out with it and it required no splicing of any wires so I can set the car back to stock if needed. That is the way chevy should have done it in my opinion.

Steve, I'd rather not have to splice wires, but I think I will unless you or someone makes a three way "device". Any ETA? I know it would sell, because that's what most people actually really want!

When I added an NPP catback to my 2010, I just ran a vacuum line to a Mild to Wild controller and had complete control of the baffles. I could open or close them at any time. Does this work the same way?

If you use the diagram, above, you won't have to splice wires. But you will have to get the bits and pieces.

As far as ETA for 3-way controller goes ... well, I have made an investment to have a bunch of printed circuit boards custom manufactured for me. I have about 200 of those bad boys sitting on a shelf.

Let me work on this.

Regards,

Steve
