I am looking to put new pipes on my m50. I want to know if I have to run the fuel controller with just pipes?
Thanks

 

Most of what I've read is the fuel controller is really only needed if the air intake side is modified. I've also read removing the battery cable after the mod will reset the CPU, and it will self-adjust for minor exhaust mods. I debaffled my pipes, and saw no symptoms of running lean after the mod.

 

hi.all da way.


I have an '07 m50 and want to remove baffle ..did u cut the plate out in back aronud exhaust and break baffle off ? theer's a you tube video on it looks easy..

the you tube guys didnt use and fuel processor but most of teh forum notes say its nt needed but one guy said he debalffled and had to add one. did u remove battery cable to reset ?

how's the sound and performance now?
