Hi guys

Yesterday me and my friend installed a catless downpipe on his M140i that has PPF, when we turned on The car The engine Light ofc pop out. We plugged in jb4 to see if it Will turn off engine Light and it did, but when we rev The car over 5k rpm it goes into Limp mode while driving.

Does any of you know or have a B58 with ppf/opf with a catless downpipe? I know that a tune or bm3/mhd would solve that but doing it with jb4 would be so much easier now that he needs The car.

I cant find anything about jb4 being able to turn off ppf/opf, maybe they havent added that function yet? If any of u guys know anything i would appreciate any help!

Best regards Satinm240i
