Summary of change:
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: [http://shop.vems.hu/catalog/vems-p-48.html 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 [http://vems.hu/vt/help/main/v3.html 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 [https://shop.vems.hu/catalog/bridgeoutputdriver-p-185.html Bridgeoutput Driver], only recommended for experienced installers ( See [http://vems.hu/vt/help/v3/v3_electronic_throttle_control.html 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, [https://shop.vems.hu/catalog/lowz-extension-channel-p-161.html 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 When you refer the project pages in the order comment (1 project per page) we take another look when processing the order
