The Valvetronic system is a BMW variable valve lift system which, in combination with variable valve timing, allows infinite adjustment of the intake valve timing and duration. The system claims to improve fuel economy and emissions, and negates the need for a throttle body in regular use.
What is a Valvetronic exhaust?
The Valvetronic system allows you to switch between being quiet and being loud with the push of a button via the included remote or through the smartphone application; this works by tapping into a vacuum source on your engine and connecting it to the control module.
Does Valvetronic exhaust increase performance?
Not only will an Armytrix exhaust increase power, but it will also be lighter than the stock exhaust, and our Valvetronic system allows you to quickly and easily change the exhaust note on the fly.
What engines use Valvetronic?
The Application — BMW uses an innovative variable control valve system, called “Valvetronic”, in their 4, 8, and 12 cylinder engines for the BMW and Rolls Royce vehicle lines. Valvetronic engines use a combination of hardware and software to eliminate the need for a conventional throttle mechanism.
Can a Valvetronic engine cause a misfire?
The main question – can the problems with Valvetronic be the cause of such (misfires/shivering) problem? Short answer – within the limits of reason: no, Valvetronic is not the cause of this problem!
What is Valvetronic sensor?
The Valvetronic sensor measures the position of the eccentric shaft in the cylinder head which controls the variable valve lift system on the intake side of the engine. The Valvetronic system essentially controls the engine speed by varying the lift of the intake valves.
How much HP gain from exhaust?
The Most You Can Gain is 2-5%
If you want to know how much power you can expect to gain from adding an exhaust system to your car, assume that your engine will get 2-5% more powerful. More specifically, large engines like a big 6.0L V8 typically see about a 2%-3% horsepower increase.
Where is Valvetronic made?
They are both Made in China but one of them claims that it’s Made in USA. FI is made in Malaysia if I am not mistaken. IPE and Armytrix are Taiwan. They are all roughly the same design internally, the rest you are paying for is the other features like remote, gesture control, app.
Can you valve any exhaust?
Valves can be installed on any size exhaust.
How much hp does a Catback add?
In general, expect a 2-5 percent increase in torque, horsepower, and fuel mileage.
What exhaust gives the most hp?
The included SuperFlow mufflers have a straight-through design for a stronger sound and added power. Thanks to the high quality craftsmanship, Gibson exhaust systems are truly enduring and will serve you well for a long, long time. With this system, you will get the highest horsepower and torque at 1800-3000 rpm.
Does cat back exhaust make a difference?
Typically, that includes a mid-pipe, muffler, tailpipe and tips. Cat-backs generally yield increases in performance, due to the more efficient flow of exhaust through upgraded parts like larger diameter tubing and better flowing mufflers, as well as improved sound and reduced weight.
What causes Valvetronic motor failure?
Typical causes could include poor electrical connections, a damaged or defective actuator motor, low system voltages, or a binding/sticking eccentric shaft. The presence of this code will typically cause the Valvetronic system to be deactivated, and in some cases, a limp mode to be initiated.
How do you calibrate Valvetronic?
Basically you reconnect everything, turn the car ON (don’t start engine), and wait. You should here the car going through the “self test/calibration” on the valvetronic motor. Wait about 30 seconds and turn the car off. Next restart everything should be ready.
