I4 owners with exhaust valve controller? I'm getting CEL

[rileydawgg]

I just installed the exhaust valve controller, and after one drive CEL came on. My obd scanner thingy isn't working so I couldn't read the codes, but while I wait for a new one, just curious if anybody else had this issue? GRP said it's probably a coincidence, and he's forgotten more about these cars than I'll ever know, but wanted see if I'm the only one...

Turbo or V6? External or OBD controller?

I4. The external miltek plug and play one.

I fit mine on my i4 3 months ago and have never had a problem. I have mine set to open at all times.

I'd double check the connectors, and also make sure the box hasn't melted.

The controller works so I don't think it's unconnected, but I'm gonna have to check it and see what the issue is. My OBD scanner wasn't working, so had to order a new one to see what the code is... maybe it is just a coincidence.

Any updates on your situation? Curious to know what the issue may have been.

Still working on it actually. I took it to the dealer to see if indeed it was something else, but they got three codes for exhaust controller. So GRP said it must be a defective controller, although it works fine. I need to take it off and then take it back to the dealer to confirm no more codes. Kind of annoying so also hoping it just will go away on its own

Hi, I want to change the exhaust sound of my Lotus Emira i4 with 360 horsepower.
I would like to hear the sound of the Miltek controller.
Or if someone can recommend me a homologated exhaust. Thanks.

The Milltek controller does change the sound. All it does is open the valves fully so it sounds like it does in Track mode but all the time. So instead of having it in sport or track mode and doing 4 or 5 thousand revs in Second Gear everywhere in towns etc. You can leave it in Tour and get a better sound at lower revs. To get a much better sound you need to fit a sport cat or similar for Aerie or GRP etc.

Did you find out what the issue was and has it been resolved?
I was told by Greg to use heat wrap so I don’t have any issues again when I reinstall everything

To really have any decent exhaust note for an i4, the most significant upgrade part is the downpipe. Different manufacturers have totally different output, we have tried more than a dozen downpipes and even HJS is no match to Mach5 that majority of Chinese owners are using; 200 cats, no cel. Combined with a value controller it is the most cost-effective way for decent sound. To avoid any overheat problem it is recommend to use the newest generation of value controller that is OBD controlled and move the value motor to a cooler location. If that is not enough for you, adding a SS or Ti muffler system will be about 20% louder and redirected the sound exit from the rear instead to the side from our OE muffler. From what I prefer, I like the sound of a SS exhaust much better that a Ti exhaust as it gives that very deep note that it does not sound like a 4 cylinders engine anymore. If you do track, it is highly recommended you heat shield the whole exhaust system or else your value motor will likely be melted.

Btw, China has one of the strictest smog regulation in the world so most of you will sound even louder than mine above and more drama. We do not even have burbles and crackles from OE.

El controlador Milltek cambia el sonido. Todo lo que hace es abrir las válvulas completamente para que suene como lo hace en el modo Track, pero todo el tiempo. Así que en lugar de tenerlo en modo deportivo o de pista y hacer 4 o 5 mil revoluciones en Second Gear en todas partes, etc. Puedes dejarlo en Tour y obtener un mejor sonido a las revoluciones más bajas. Para obtener un sonido mucho mejor, debe adaptarse a un gato deportivo o similar para Aerie o GRP, etc.

Thank you

Para tener realmente cualquier nota de escape decente para un i4, la parte de actualización más importante es el downpipe. Diferentes fabricantes tienen una producción totalmente diferente, hemos probado más de una docena de downpipes e incluso HJS no es rival para Mach5 que la mayoría de los propietarios chinos están usando; 200 gatos, sin células. Combinado con un controlador de valor, es la forma más rentable de un sonido decente.Para evitar cualquier problema de sobrecalentamiento, se recomienda utilizar la nueva generación de controladores de valor controlados con OBD y mover el motor de valor a una ubicación más fría. Si eso no es suficiente para usted, agregar un sistema de silenciador SS o Ti será aproximadamente un 20% más fuerte y redirigirá la salida de sonido desde la parte trasera hacia un lado desde nuestro silenciador OE. Por lo que prefiero,Me gusta mucho más el sonido de un escape SS que un escape Ti, ya que da una nota muy profunda de que ya no suena como un motor de 4 cilindros. Si realiza una pista, es muy recomendable que proteja contra el calor todo el sistema de escape o, de lo contrario, es probable que su motor de valor se derrita.

Por cierto, China tiene una de las regulaciones de smog más estrictas del mundo, por lo que la mayoría de ustedes sonarán aún más fuertes que la mía anterior y más drama. Ni siquiera tenemos burbujeos y crujidos de OE.

¿Este video es solo sobre el intercambio de downpipe? Tengo un Mercedes GLC43 AMG y suena mejor que el Emira i4
