Hi I noticed on a thread that Someone ? mentioned - the JB4 gets rid of cel if I get - VSRF non-catted downpipes-I have it on my 2017 F85 X5M the -Jb4-W/BCM BT dongle /NOT ANY BUT STOCK DP’s (ERYTIN) lol - For iOS ,,, Is this true ? / I live in CT it needs to pass readiness that’s pretty much it - so the Jb4-W/BCM - can aliveates this ? Really -i’d love to hear more. I would love to get uncatted down pipes for my car WITHOUIT T triggering CEL, and always a rich mixture,, and or getting a flash tune.-Coding it out is stupid (Just masks not fix)./now if I had a 100% answer that a spacer or a 45° angle bung would work (An Fit) but nobody gives me a 100% answer. So I don’t like to take chances and I don’t like the odds unless it’s 100% yes it works or no so can someone please give me a 100% answer and or explain how to do this. I would be Very appreciative! Thank anybody and everybody ahead😊-I am also looking for good downpipes for sale used or new /// also have Parts from E-70 X5M and a little bit of newer (Complete airbox assy)
