Putting in real world terms that everyone can understand, a stock early 2014 335i PWG and an identical stock late model 2014 335i EWG line up at the track (a comical real world scenario as I don’t track cars or intend to). As close as can be guesstimated in this scenario, what is the real world difference in the times and speed going to be? 0-60 and Quarter Mile? |

EWG is obviously better, but trying to quantify it in real world results. Would it shave a tenth of a second off time (or more) or give you 2 mph difference (or more)? I seriously do not know which is why I am asking. Moving from theory to reality, what is the end result in the real world? |

Dont wanna hijack, but I figured I would ask here. would PWG/EWG matter if I'm going PS2?

Just like in boxing, one can win a round (or the title) with precision or doing it sloppy. End result is the same. That is why I am trying to understand is how much real world difference there is in EWG v PWG. |

so would it be worth it to do a PWG to EWG swap while upgrading turbos?

look at F30 328i. It has exactly same turbos just from year 2013 is EWG, while year 2012 is PWG. Is there any difference in performance? Don't think so. BTW F10 M5 both turbos are PWG. So?

Want to bump this to the top.
I have read there is an additional pin on the EWG dme that can be activated by a tuner allowing the S55 dual fuel pumps to be used. I will be doing a PS2 upgrade at some point in the next couple months and if I’m going to spend that much for the turbo and supporting mods, I would spend the additional money for a used EWG dme and have it aligned (I currently have PWG). My understanding of the switch. 1. Source used EWG dme, have aligned to vehicle 2. Change to ewg wiring harness (may only need part of it from looking at realoem) 3. Install ewg PS2 with matching downpipe, cap pwg vacuum line That should be the basics. I’d also be interested in more info on EU5 vs EU6 injectors |

Like I said, I can’t confirm first hand. If it is used on the Alpina B3, it would be a good place to start. |

So the kit would work with a EWG, but where is proof of concept that a car can be retrofitted to EWG from PWG? |

Why would a car not be able to be ewg if the dme and supporting hardware are used? The biggest hurdle is aligning the used ewg dme to a pwg car. I have not found anything that points to ewg extending into other control systems past the dme. The simple hardware/software change is probably why some people that have a build date that falls in the ewg cutoff are sometimes surprised to find pwg, assembly line used what was available.
A new dme may not even be required, I was looking at the newer version for the ability to run the s55 fueling. |
