Note: 3 projects interleaved is confusing, so page HAS BEEN split, see links below

This page: BMW S38B38 (M5 E34 3.8L euro version) turbo engine with (6 cylinders)

----

Sibling BMW projects (same installer):

* MembersPage/TahitiBmwSfourteen

BMW S14B23 (M3 E30 2.3L euro version) turbo engine

* MembersPage/TahitiBmwSfifty BMW S50B32 (M3 E36 3.2L euro version with VR,VR,VR double Vanos )

** motronic88 is good option for S50B32 (econoseal VEMS ECU with the right options also controls it, but more work)

Make sure the correct trigger options are chosen, and strongly advised: in order comment refer to these wiki pages (max 1 project per page).

TODO: mention basics at top of pages, like "6cyl" or "4cyl" (and preferrably firing order also, eg 153624 or 1342)

Generic advice, applies to all 3 engines: [VEMS ECU supports all]

* Primary rule: CHOOSE DEFAULT if unsure (eg. 1-wire, ETC-interface, ...)

* 6 High Z (saturated) injectors which I want to control them in Full Sequential Procedure

** => no problem with camsync connected and configured properly

* What’s the meaning of : “ 1-wire interface” ?

** if you do NOT know, do NOT need it, choose the default : +1 analog input more useful instead of 1-wire (which can be used for ButtonImmobilizer )

** Look around in [VemsTune Help] v3 dialogs, primary source of information

* What’s the mounting style "no screws"

** photo: GenBoard/VerThree/CaseAndMounting

** choose default (flanged), or "no screws" if space is extremely tight (enough for 173mm, but not enough for flanges ~195mm)

* Ignition Driver : I have taken the 6+2

** for 4 cyl, or if you plan to use passive coils, choose 8 IGBT

** on 6 cyl, if uncertain (to be determined later: perhaps 6 active coils, perhaps 6 passive coils) choose 6+2

** remember the 4 stepper outputs can be used for 4 active coils

* bridgeoutput interface: only useful if also ordering [Bridgeoutput Driver], only recommended for experienced installers ( See [VT help] only recommended for experienced installers (please do NOT use DBW for first install)

BMW S38B38 (M5 E34 3.8L euro version) turbo engine with (6 cylinders)

6 High Z (saturated) injectors which I want to control them in Full Sequential Procedure

Ignition: with wasted spark coils pack which I want a wasted spark procedure

2 knock sensors already installed on the block

1 External map sensor connected in the Inlet Manifold

Questions :

-And could please confirm my choice of the primary trigger : VR and the secondary trigger : VR ?

See trigger below (and measure).

"I really want to order these parts from manufacturer not from reseller."

The only requirement is to edit these pages: maintain thematically (as in wiki, not chronologically as in email or forum), and non-interleaved (separate page for each project).

Trigger

* measure primary and secondary trigger:

** if you find 2 pins with same resistance (usually between 350 and 1500 Ohm) in both directions, that is VR sensor. Otherwise HALL.

** take note of resistance

When you refer the project pages in the order comment (1 project per page) we take another look when processing the order
