Great video! I also love this tune. I did find, though, that the “standard” idle increase was insufficient to reduce the NVH associated with stiff engine mounts. The tune raised my idle from 800 to 900, but I needed 1,200 to get rid of the NVH. I asked BJ to up the idle, and they did so, but said they would not go above 1,000 due to liability reasons. I’m okay with that. If you have stiff aftermarket mounts, I recommend you ask for 1,000 RPM bs their standard idle increase.

thanks for sharing your experience! Yes, the car became undrivable when I had to briefly re-flash back to stock. The BJ tune for the engine and transmission really made a difference lol.

Had a golden convertible e46 m3 about 10 years ago. Still kind of miss it.

Amazing video bro!

[@HazardGarage]

Thanks!

[@buildjournal]

Thanks for the review!

[@leonhu3056]

can you pass a smog check after the tune?

[@HazardGarage]

in California, you will need to revert back to stock tune. not sure if you can flash the SMG tune by itself and pass smog though.

[@MEMcAndrews]

Mine passed in Georgia, no problem. All equipment is stock, though (I.e. cats, headers, etc.)

[@jeobanilopez3749]

Would this tune work with a 330ci non-m ???

[@HazardGarage]

unfortunately it looks like they only offer tunes for the M3

[@dailydrivendiecast]

That thing is beautiful, so what's your daily?

[@travdripdrip382]

[@HazardGarage]
