Emissions Issue w/Full CSL Hardware/Firmware Conversion

Thanks. I’ll definitely going to look into.

Off topic but once you get your emissions stuff figured out you should consider running Bry5on ‘s mullet tune.

I just swapped an HP DME into my ’02, which previously had the Kassel CSL tune—and it was remarkably bad. Bryson created a custom file based on my mods and requests, then walked me through flashing the car over a quick phone call.

In the city, it’s smooth, predictable, and compliant. Drives like the car is bone stock. When I open it up, it’s insanely responsive and snappy. 10/10 recommend.

Kassel themselves offer a solution for this, have you asked them about it?

I'm currently running Kassel's CSL conversion for my Karbonius airbox. What I didn't know before I chose that over Alpha was that U.S. Emissions Systems can't connect to the ECU now beause it's Euro spec'd. Makes sense, I just simply didn't think about that, nor was informed going into it.

The CSL conversion is great. The only issue I have is with Emissions. I know one option is getting another ECU + Alpha tune and swapping that in for emissions and swapping back to the CSL post emissions, which obviously isn't cheap, so I was wondering what other members are doing as a workaround.
