Emissions Issue w/Full CSL Hardware/Firmware Conversion

In theory yes, but why would anyone go throgh the trouble of removing the box just po pass smog/emissions
-
We could also just buy a used HP DME have that flashed with CSL firmware/EWS delete what not and swap to our original virgin DME when it comes time to smog right? (provided we also remove the airbox etc)Originally posted by simplem3 View PostJust to close the loop on the original topic - if you’re like me and you’re running the CSL (euro) firmware, which isn’t a tune, and are required to get emissions done in your state, your only option is run your DME with a tune, e.g., Alpha-N or another tune that is programmed to run the airbox.
With the CSL fireware conversion, the original fireware on the unit is replaced with CSL fireware which is euro spec and therefore does communicate with US Based emissions systems. That is my current issue.
What I’ve opted to do is buy a used DME and have it flashed with the Alpha-N tune. So for emissions, I’ll have the option to swap in the Alpha tuned unit and for regular driving I’ll run the one with the CSL firmware.
As for the mullet tune, it doesn’t help or solve the emissions issue. Based on my understanding, the Mullet tune is flashed on top of the CSL converted DME. However, sounds like it’s pretty good so I’ll be looking into it after emissions and once my euro headers and cats are installed.

Does Bry5on have separate contact info?Originally posted by AWE46M3 View PostOff 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.

Is Paul Claude still around for tuning?Originally posted by usdmej View Post
I had a CSL tune with working flap done by PCS (Paul Claude) tuning that ran great but wouldn't communicate with california emissions computers. I was told Kassel had a solution to this so i sent them my ECU and after a couple of back and forths (and customer support that i can best describe as, casual) my car was able to be read at any smog station. with a small caveat being you had to plug the car into obd2 and turn the ignition off and on again
i asked them specifically what they did to make it work but they would not elaborate which is understandable

haha yea that’s the thread where i first read about the mullet tune. As soon as i read that he daily drives it and there’s no typical alpha n bucking at low speeds or throttle response delays, it had me intrigued. I’m new to this forum/ website so idk how it works. I tried sending him a message but it said i don’t have authorization? Do i need to subscribe to him first in order to send a message?

Mullet tune is what Bryson calls his tune. Business in the front (drives like it’s bone stock) but party in the back (delivers strong and predictable performance when pushed) hence mullet tune.

How does it compare to hassan’s hte tune? Also how much is the mullet tune? I haven’t been able to find much info on it

The CSL software that is installed is the full CSL firmware. Once installed your DME officially because a euro spec or non-U.S, therefore the U.S. emissions systems are no longer able to talk to it.
I either need to flash a second DME with Alpha and swap it in for emissions or send my current CSL DME back to Kassel to have it converted back to U.S specs and flashed with Alpha for emissions. And then rinse and repeat back to CSL.
Originally posted by Zekarus View Posti'm not sure but i guess the csl software doesn't have US smog integrated as it was never sold there. so they flashed a non csl, US software with Alpha-N instead of MAP and that's why it's working.

Once complete, I’d send the DME back Kassel to get it converted back to the CSL firmware.
what solution are you referring to exactly?
