Visit Preferences to set your user name Summary of change: Car is my friends '86 928 S with 4.7litre V8, Strosek body kit and ultra-wide Folger 18inch wheels. Engine produces 310hp stock. This is the beast: http://www.carrating.org/documents/cars/u/U3R3o585q6Z5p5o1x252.jpg It has LH-Jetronic from the factory. LH is fuel only, so spark is distributed by two(!) 4cylinder dizzys! That's going to change because I threw old engine compartment wiring off and ignition is going to utilize VW COP's. Car has 100-1 tooth wheel on the flywheel with VR sensor. What '''redline RPM''' are you aiming ''?''' A: No more than 7000rpm ------ 14.09.2006 Hooked a customers VEMS box to the VR sensor to get trigger config ok until cars box arrives. After some tweaking I got steady rpm signal without trigger errors. So, one (probably the biggest) obstacle is defeated! ------ 21.09.06 Got the new connectors for the COPs (VAG part number 036 905 715 A) and trying to figure out the pinout for them. It seems to be the same as the ones at the COP page here (pin1- +12V supply, pin2- Ground, pin3- +5V signal and pin4- Ground), but can anyone confirm this? I measured the resistance between pins. it's like that: Between pin 1 and 4 = 390 ohms, between pin 3 and both 1 and 4 40kOhm and betweens pins 3 and 2 16kOhms.
