I'm in the middle of adding PI to my car, an early '12 135i with pwg N55, and I thought I'd share my project. Thanks to help from @houtan and @Stokes I have been DYI tuning my car for a while and feel happy with the results so far (always learning tho). Now thanks to Houtan I'm adding PI to take my car to the next level. Houtan basically gave me his "wish list" and I just ordered all the parts so he can live vicariously thru me, thanks Bro! lol
Below is my parts list:
Walbor 535 bucketed LPFP (aka Stage 2.5 v 2) from Precision Raceworks
BPM4 LPFP controller from EOS
PI manifold from EOS
Reflex+ PI controller from EOS
Reflex Flex Fuel sensor (basically a GM flex fuel sensor) from Motiv
Reflex 0-10 bar pressure sensor (used on the LP line) from Motiv
Flexible fuel line and fittings from Performance Fueling Solutions
I'm not going to document the things that already have been documented, like swapping the intake manifold or the LPFP but I'll share anything I figured out on my own or that I didn't find when watching others videos. Below are pix of the parts as I received them plus I'll share pix of stuff either not documented or that are different than what is documented.
PI manifold
Had to make sure there were no drugs, body parts or bomb materials, lol
LPFP
ReFlex parts:
BMP4
