Car: 335i touring was 320d
Default Hi everyone,looking for someone good with 335i management in Hertfordshire - 10-17-2016, 09:29 AM

Hi guys

I'm new here,just recently converted my 320d to 335i but now having some drama getting her to run properly.

I have tried data logging through jb4 and it shows some very strange stuff I.e all sensors being logged going to zero at certain spots and practically zero boost!

It's driving me crazy now as I know my way round an engine but this is racking my brains lol

Any help or if you know anyone who could help with this please let me know

Cheers guys

Your first, and probably cheapest route would be to grab a log with the JB4 and post it in the support section of this forum:-


If possible, take the log in 3rd or 4th from 2500 to redline

Given you comments, pre taking the log, check all the JB4 connections, that it has the latest FW, has all options set a default and that you're using the latest interface.
