Thanks. I think so too. Its a slightly different design and the rectangle box is probably a resonator..

Can I just drive around with the CEL, or does the car cut power completely once the error message pops up?
This.
It doesn't happen often, but it's annoying and can be dangerous in some conditions (the engine cut power at 2000rpm).

The CAT-delete solution is ready, the OPF-Delete has a working prototype. If the virus situation would not have been a problem, it would have been in my car to run beta tests, but we can't test right now.

As soon as opens up again, testing will continue, according to my contact. For the beta run they will need some people to test, but as soon as that becomes a point I will reach out to you guys.

The final word is out. The OPF-Delete ECM product is dead from my point of view. The company Awron Automotive who was developing it, has not been able to deliver what they have promised for more than a year now. It is the same person behind the company that is not giving support anymore for your Awron display. It is an one-man band right now who is unable to deliver the things he said he would deliver and which I then converted to you guys as a solution for our situation.

Over the past months, the product was promised to me and many dealers I spoke to at least more than 50 times. I even went to the office of the company mid-March to hear the latest, but now two months later nothing is there. There was a working prototype according to the owner of the business, but no further steps were made and I never saw it working.

It is a pity of course. I put more than 100 hours in this project hoping to find an option for everyone that looked out for a solution to remove his OPF without having to alter the tuning file on his car. The owner and developer of the product is simply not trustworthy enough to do business with anymore and I feel I need to take a distance.

He doesn't understand that they are clients waiting for the product and he is unable to finish it in a timely manner. Add to this to the fact that contacts of mine have experienced his inability to make it widely available for dealers and customers in the future at a decent price offer, and for me it all came together. There is a time you have to stop pulling a dead horse.

I have now decided to step away from the project knowing that it won't ever be released any time soon. It is what it is... The project is dead, and the only two options you can opt for now are to disable the sensors in the ECU or fit the AK Motion solution.

For some reason the ECM module from Manhart for G20/21 is also removed from the store - is this associated somehow? Btw Don’t you know whether there are any solutions for G chassis? I am with you in this fight!

  • pureboost.de OBD unlock and OPF delete in the DME (Which again my dealer can spot if something went catastrophically wrong and I needed the warranty)

Which would you personally recommend? Fuck the warranty and flash away, or get the data display with the plastic cable clips everywhere in the car's Canbus?

Is it possible to the data display OPF delete without the display itself?
My car has the OPF-Delete fix in the ECU tune, and I have no issues with warranty cases. All depends on the relationship with your dealer, as I always have said.

No, you need to have the OPF-Delete cable and display together. The brain power is in the display. The OPF-Delete is just a cable going from the OPF sensor control unit to the data display.

Yep, MANHART has fully removed the product range from their website and web store. You can ask MANHART for the reason why that happened.

You can always install the display in the glove box, and lock it when you go to the dealer or simply remove the display and disconnect the controller, This is what I'm intending on doing (it's simple enough). I am also thinking of extending the wiring loom from the connector in the side wall box directly into the glove box which will make disconnecting it simpler.
Also I don't like the fact that I will losse a vent, it gets up to 120 F in the summer.

Hello, am I reading this right? US cars do not need to be tuned if you replace the full exhaust system from the DP to the muffler? All of this without throwing any codes, or limp mode?

Correct

If you leave the factory DPs, primary cats and O2 sensors in place you shouldn't have any issues replacing the rest of the exhaust system

On EU car with opf I have now akrapovic slip on.
I intend to replace the resonator for loud sound.
I saw remus ( straight pipes), dinan ( x pipes) and supersprint ( H pipes).

I wonder if anyone works without CEL/ limp mode?

How do you like slip on Akra in comparison to stock?
Has the sound became louder? Is the difference noticeable?

Can you please make a video with the sound of Akra slip on?

I was about to order Akra but before doing so I came to hear Akra on my friend’s car in person and didn’t like the sound. But my feeling is that maybe it had some defect and that was the reason of poor sound.

You give me homework when the internet is full of recording made with professional tools.

It s hard for me to believe that what I record with phone will be relevant to you.

Here is the M2C (HS) with Akra and my M2C (LBB) with OEM exhaust

I didnt like the Akra sound in person on this particular car. It sounded louder but it sounded as if something is wrong with the sound. There was some strange sound in person as if some metal parts are broken.
And having heard that car in person I cancelled my order for Akra. The guy told me that he had some problems with the valveson his Akra



And later on I met the guy with M2C with Akra slipon + midpipe amd the sound was amazing.
