F10 535i shuttering SOLVED

F10Ulices · 08-12-2023, 03:38 PM

I have a 2011 535i n55 FBO with jb4+ and mhd piggyback tune. My car runs good on mhd map 1 but on map 2 or 5 it shutters on wot then it goes into limp mode. The car has a brand new hpfp, lpfp, fuel injectors, precision coil packs and a gfb+ spacer.

Check condition of spark plugs and inspect/clean MAF sensor, replace if necessary, Inspect and clean your air intake/filter, inspect your valves if possible, or clean them, All of these are very low cost except if you decide to walnut blast, (Labor and cost) are videos how to use a valve cleaner and works effectively (if on a budget), Also do not leave out your Vanos Solenoids out of the question. I can only imagine your car moves and sounds like a beast! If there is an engine light, after limp mode, you can get the codes read and look here for solutions for the codes!

Spark plugs were regapped to .024 but they were fouled, i havent touched my maf sensor but ill give that a cleaning, i have a BMS intake and i cleaned it couple weeks ago, i put the valve cleaner every 6 months but im going to put the camera in to see better, and i wasnt aware of any vanos issues so i will look into it. I just contacted jb4 technical support and i will be making a log i will post it to see if you guys can understand it. I actually also relized it shutters on map 1 sport mode but not map 1 normal mode.

JB4 was causing my car to do some weird shit. If everything else checks out, I'd dig deeper into that. Made my car act like the trans was slipping. Sometimes she'd go into limp mode. BM3 flash fixed it. Some cars don't like the JB4.

I had the similar problems with piggy back. Ngk one step colder plugs resolved the issues .

0.028 approximately. They came pre-gapped
