Summary of change:
'''Please add your coments for my first VEMS project.''' Here is inconvenient to find rigt thread for newbie... :( For first want to put VEMS on BMW M50 modified engine with COPs for dragrace. It is 6cyl 24V DOHC engine bored up to 3L. Deeply rebuilded head, very agresive cams for this stroke. Custom make intake system with large reciever. And more. *'''Why I want to put VEMS because:''' ** 1)COP (general) ** 2)WBO2 on board ** 3)sequential injection *'''What features I can't find:''' ** 1) Launch control! ** 2) traction control for beter acceleration control in first gear(rough like MSnS-Extra have) ** 3) ignition retard due hot intake and advance for cold engine ** 4) two engine maps ('street fuel/race fuel' alike) ** 5)progressive shift ligts. and more All of theese functions is useful or even prerequisite for succeseful drag with revy engine. '''Is here code for some of theese useful functions?''' ---- *'''My shopping cart looks so:''' **1 x VEMS sticker **1 x Alubos EC frontplate **2 x Alubos gasket **1 x Alubos Endplate **1 x Alubos1600 **1 x Additional VR or Coil interface (both sensors is VR) **1 x Dual channel knock sensor interface (just for experiment) **1 x EGT input amplifier (just for experiment) **1 x Econoseal18-PCB **1 x Econoseal18-Wire **1 x Econoseal36-PCB **1 x Econoseal36-Wire **7 x Ignition driver **8 x Injector or WBO2 heater driver ('''how much FETs need one low-Z injector chanel: 1 or 2???''') **1 x Wideband O2 sensor **1 x Ignition driver insulator sheet **1 x LCD4x20 **1 x Wideband connector **1 x Genboard v3.3 '''Is thomething miss here?''' ---- '''Q: May be better is to put Genboard PCB inside Motronic ECU?''' A: The Genboard case is much easier to work with and will allow better cooling/clamping for the injector (FET) and ignition coil drivers (IGBT). I assume you have the 55 pin connector, it will be a lot of patch work to make it work with the original harness - it's a better idea to custom make your own harness, and within reason to also re-use some parts of the stock harness. ---- **
