Summary of change:
I'll be converting my Volvo V70 XR AWD over to VEMS to take advantage of the Precision PTE 6262BB turbo I am installing. I plan to build the VEMS 3.6 into a Motronic ECU case and use as much of the stock wiring as possible. http://i27.photobucket.com/albums/c190/huseinholland/CarMods/IMG_9364.jpg I already have a separate COP setup through TurboTunerUSB, so I will need to include new wiring from unused pins in the ECU for the logic level outputs. I plan to leave a stock (modified for no CEL reporting) ECU in a bridge connector to retain the instrumentation & basic OBDII output for state inspection purposes I want to retain items from the existing ME4.4 such as the AC/2 speed fan functionality, Barometric pressure compensation, dual knock sensors and Accelerometer (if possible). The main item I have to add is the MAP/MAT (038 906 051) , I'm going to use the Bosch/VW item. I can repurpose existing wiring from the EVAP valve for that. EDIT: ordered the 4bar MAP from the UK: 03K 906 051 The WB02 will be installed in place of the existing rear O2, I just have to add one wire to the stock harness for that. Main Engine harness mostly ready. http://i27.photobucket.com/albums/c190/huseinholland/CarMods/IMG_0253.jpg WBO2 wired where Rear O2 used to go, added wire for Nerst http://i27.photobucket.com/albums/c190/huseinholland/CarMods/VEMS%20INstall/IMG_0266.jpg MAP installed in intake http://i27.photobucket.com/albums/c190/huseinholland/CarMods/IMG_0231.jpg IAT in intake pipe http://i27.photobucket.com/albums/c190/huseinholland/CarMods/VEMS%20INstall/IMG_0267.jpg VEMS board arrived - so assembly & install in Motronic box is next http://i27.photobucket.com/albums/c190/huseinholland/CarMods/VEMS%20INstall/IMG_0261.jpg started laying out board connections http://s27.photobucket.com/albums/c190/huseinholland/CarMods/VEMS%20INstall/v3_top_channels_and_pins.jpg heat sinks http://i27.photobucket.com/albums/c190/huseinholland/CarMods/VEMS%20INstall/IMG_0503.jpg Motronic wiring http://i27.photobucket.com/albums/c190/huseinholland/CarMods/VEMS%20INstall/IMG_0713.jpg Rebuilt engine is back in the wagon, so I'm ready to get back into the VEMS http://i27.photobucket.com/albums/c190/huseinholland/CarMods/IMG_0800.jpg a US Volvo forum member found this for me: http://i27.photobucket.com/albums/c190/huseinholland/CarMods/VEMS%20INstall/IACcontrol.png Which would appear to resolve my dilemma as to how to proceed with wiring for the stock IAC valve. Finished wiring the Motherboard to the Motronic connector http://i27.photobucket.com/albums/c190/huseinholland/CarMods/VEMS%20INstall/IMG_1414.jpg Epoxied wiring to prevent issues with potential movement http://i27.photobucket.com/albums/c190/huseinholland/CarMods/VEMS%20INstall/IMG_1415.jpg Main connector in place http://i27.photobucket.com/albums/c190/huseinholland/CarMods/VEMS%20INstall/IMG_1416.jpg Now I need to start learning the software & configuration for my setup.
