BMS Chargepipe and Downpipe

marcm · 11-10-2014, 05:58 AM

I have N55 335i and just purchased and wondering if there is any coding required to fit both pipes ?

I see that the o2 sensor needs to be transferred from cat down pipe to BMS down pipe.

Just thinking of getting local indy to do the swap.

Thanks
Marc

Yes you'll get a check engine light. Most tunes available (JB4, Cobb, procede, remap) will cancel this..

Is there any way to just cancel the check light as I would like to just run with the +30 extra hp the charge and downpipe will give ?

You won't get 30bhp from those mods alone. DP's maybe 10hp max - cp gives no extra power.

You can buy an O2 simulator (from BMS) which cancels the code. For not much more you could get a used JB4 and just block the code using that.

If your going to fit a mod which causes problems (MOT failure and voids your warranty) you may as well get the full benefit (60-70hp)..
