Welcome to BPC's all inclusive resource for Diesel Tuning. Here at Bimmer Performance Center we take pride in our BMW Diesel development, From spending hours on the dyno to welding custom fit exhaust for an E70 X5.  We have spent hundreds of hours in R&D to build the most reliable tune for your M57 for both on and off road use. BPC also offers intake manifold cleaning services (CBU), engine rebuilding, and custom turbo installations.

Here's a quick run down of the most commonly asked questions pertaining to diesel race conversions.

Additional Diesel Q&A

With the tune, the DPF needs to be removed and the only senors still in place are the ones that will go back into the new downpipe. The egr gets blocked off on both sides, and the SCR filter needs to be gutted or removed.
 
 If you want to remove the tanks that is fine but both tanks need to pulled out and all of the sensors need to be removed/ unplugged from the harness so that the car does not think that they are still in the tank. 
 
Q: So if I leave the tanks in place I can leave the sensors plugged in or do they have to be removed?
A: If you leave the tanks in place, then you would leave the sensors still in place on the tanks
Q: The 2 vacuum lines that run to the dpf, do they get capped off? 
A: Those 2 lines and the sensor they run to can all be removed.
Once everything is taken care of, and the computer reinstalled you can fire the car and sometimes a few lights will come on but a test drive should take care of them. If any other faults are present clear the faults and test drive again. If anything is persistent and comes back and is an actually DDE fault then give us a call and we an help troubleshoot. 
 
The most common issues are that sensors are still left in place and they will throw codes, or during removal of the DPF some of the old vacuum lines will crumble to collapse and now allow the turbos/ EPDW to work like they need too. You can tell this issue when the car has no boost or only has boost either down low or up high.

  • A: We recommend sizes from 500cc/min to 1000cc/min for max performance

  • Q: When should I start injection?

  • Q: Should I have the nozzle in front of the charge intake air sensor?
  • A: No, on a diesel, intake air temps do not control fuel injection timing. Fuel injection timing adjustments are controlled by fuel temperature.

  • Q: Where do I need to install the boost reference and nozzle?
  • A: Both the nozzle and boost reference need to be installed post intercooler. The boost reference needs to be installed before the meth injection nozzle in order to keep any liquid from entering the boost line.
