3 BMW-s from French Polynesia in Tahiti. (answering initial email req - keeping the bad "3 projects interleaved" style for now) TODO: page must be split, max 1 project per page and mention "6cyl" or "4cyl" (and preferrably firing order also, eg 153624 or 1342)
- BMW S14B23 (M3 E30 2.3L euro version) turbo engine
- BMW S50B32 (M3 E36 3.2L euro version with double Vanos )
- BMW S38B38 (M5 E34 3.8L euro version) turbo engine with (6 cylinders)
Extract: [VEMS ECU supports all]
Make sure the correct trigger options are chosen, and strongly advised: in order comment refer to editable pages (max 1 project per page, so split this)
- 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)
I would like to have information before place an order for different ECU VEMS V3 for 3 different BMW engine turbo projects and all the parts that I will need to install all of these.
So I have 3 BMW engine projects that I have turbocharged, all have new parts in and on it.
1st one is an BMW S14B23 (M3 E30 2.3L euro version) turbo engine with (4 cylinders)
4 Low Z (Peak and Hold) injectors which I want to control them in Full Sequential Procedure
Ignition: with wasted spark coils pack which I want a wasted spark procedure
1 knock sensor already installed on the block
1 External map sensor connected in the Inlet Manifold
1 Exhaust Gaz Temperature already installed in the exhaust piping
1 Boost Solenoid connected to an external Wastegate
The Primary Trigger is: VR
The Secondary Trigger is: VR
BMW S50B32 (M3 E36 3.2L euro version with double Vanos )turbo engine with (6 cylinders)
6 High Z (saturated) injectors which I want to control them in Full Sequential Procedure
Ignition: with individual coil which I want a Full Sequential Procedure
2 knock sensors already installed on the block
1 External map sensor connected in the Inlet Manifold
1 Exhaust Gaz Temperature already installed in the exhaust piping
1 Boost Solenoid connected to an external Wastegate
The Primary Trigger is: VR
The Secondary Trigger is: Hall
The 3d one is an 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
1 Exhaust Gaz Temperature already installed in the exhaust piping
1 Boost Solenoid connected to an external Wastegate
Primary Trigger is: VR
Secondary Trigger is: VR
I have taken the following different options on your website for each engine:
So could you please tell me if I’m ok or not in each selection of these options for each ECU VEMS and correct me if I’m wrong please?
For each ECU, I will post questions about them.
For the 1st one: BMW S14B23 (M3 E30 2.3L euro version) turbo engine
- 1-wire interface NO
- EGT input 1
- ETC BridgeOutput_Interface 1 => No please !
- Flyback LowZ active flyback 4ch
- Hi-side PFET outputs 4
- ignition driver 4
- Knock input channels 1
- LCD connection yes
- MAP connection offboard (electronic)
- mounting-style no-screws
- primary_trigger EC36/27 VR
- secondary_trigger EC36/13VR
- Special requests no
- withSDcard removable
Questions:
-For the : “active flyback" is a must for low-Z injectors (universal: can be used for high-Z too)”. Is that means that as now as I have mounted low Z injectors on this block and if I want later to go to High Z injectors this will be ok to control them with this ?
- YES, [active flyback] installed internally => suitable for either High-Z or Low-Z
-For the Ignition Driver : I have taken the 4+4 : 4 IGBT+4 Logic-level output, is it good ?
For 4 cylinder, either 4+4 or 6+2 is good choice (these can do 4 ignout, or wasted spark 2 ignout of course; either passive or active coils)
-And could please confirm my choice of the primary trigger : VR and the secondary trigger : VR ?
For the 2d one : BMW S50B32 (M3 E36 3.2L euro version with double Vanos )
- 1-wire interface NO
- EGT input 1
- ETC BridgeOutput_Interface 1 really ??
- Flyback HighZ-only 30V flyback
- Hi-side PFET outputs 4
- ignition driver 6+2
- Knock input channels 2
- LCD connection yes
- MAP connection offboard (electronic)
- mounting-style no-screws
- primary_trigger EC36/27 VR
- secondary_trigger HALL isn't S50B32 VR/VR ?
- Special requests no
- withSDcard removable
Questions :
-For the Ignition Driver : I have taken the 6+2 : 6 IGBT + 2 logic-level so I will be able to go to a full sequential procedure with this with individual coil isn’t it ?
-What’s the mounting style no screws, do you have a photo of this please ?
-And could please confirm my choice of the primary trigger : VR and the secondary trigger : HALL ?
-Confirm me that I will be able to control the Dual Vanos with this selection ?
For the 3d one : BMW S38B38 (M5 E34 3.8L euro version)
- 1-wire interface NO
- EGT input 1
- ETC BridgeOutput_Interface 1 => NO please
- Flyback HighZ-only 30V flyback
- Hi-side PFET outputs 4
- ignition driver 6+2
- Knock input channels 2
- LCD connection yes
- MAP connection offboard (electronic)
- mounting-style no-screws
- primary_trigger EC36/27 VR
- secondary_trigger EC36/13VR
- Service ASAP
- Special requests no
- withSDcard removable
Questions :
-And could please confirm my choice of the primary trigger : VR and the secondary trigger : VR ?
See below (and measure).
I have taken a lot of other parts in the cart like Econoseal 18-wire side, Econoseal 18 harness, Econoseal 36-wire side, Econoseal 36 harness, USB to RS232 adapter FTDI, Molded Serial Cables …
"I really want to order these parts from manufacturer not from reseller."
OK, just
- split this to separate pages (noninterleaved, max 1 project per project; and minor cleanup)
- 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
