Hey guys, according to the JB4 app and my awesome OTG cable, my car hot 16lbs of boost in 3rd gear. I have the BMS DCI and the JB4. Other than that stock from what i know. Also, i am getting these codes:
29F4 - Catless downpipes detected
29F5 - Catless downpipes detected
2EFE- electrical fan Input signal

No check engine lights on, also no missfires or engine codes. Car is a 2010 335xI

Will post logs as soon as i get the chance to do 3 WOT runs. (i Have one WOT run logged will post that soon)

Obviously not stock and has been tuned previously or you will not be getting fault codes for down pipes.

Here is one log

Looks like i hit 14.1 Lbs of boost, which seems much more reasonable. Let me know if anything looks off

Thanks again guys

i heard from a buddy of mine that those fault codes could also be from a bad O2, Is that a possibility?

I doubt you would get those codes from bad o2s. For one, they probably would not go bad at the same time. And they still have other wires that can feed back other data. So if the codes say no cats, then they have probably been removed.

These logs are too short to be useful for much but if you want free tuning advice for the JB4 just post longer logs to BMS' support forum!
