Summary of change:
= Trigger Setup = MembersPage/AntonLilja for '''5cyl 20VT audi engine''' ---- '''Trigger setup plans''': * '''Primary trigger VR, 60-2 wheel on the crank pulley''' ** Any generic VR sensor in a custom bracket attached to the oil pump, 60-2 missing tooth wheel from [http://www.034motorsport.com 034Motorsport] centered and welded to the crank pulley * Secondary trigger HALL, a vane wheel and fork style sensor on the back of the cam wheel ** '''with 60-2 primary trigger, the sectrig pulse can be almost anywhere: keep it min 18 degrees away''' from the primary trigger tooth that comes after the missing gap. ** the best placement is probably 72 deg ATDC (any cylinder: ign outputs can be rotated easily). reason: this position is also outside the ignition window (typically 45 BTDC-50 ATDC with ALS), a requirement of old 1.0.x firmwares. ** I'm first gonna try this with the fork sensor from a distributor and a custom window wheel, alternatively I could use the stock cam pulley and hall sensor from the ABY/AAN engine. ---- '''Some images of a stock cam hall setup:''' http://www.vems.hu/files/AntonLilja/DSC00558_JPG.jpg http://www.vems.hu/files/AntonLilja/DSC00561_JPG.jpg http://www.vems.hu/files/AntonLilja/DSC00554_JPG.jpg ''''If the sensor pulls down to ground, or outputs 0/5V signal''' (or min 0/3V) than it's '''easy to use with VEMS, choose sectrig=HALL in webshop.''' * '''if you use 135 tooth primtrig and also crankhome VR''': ** one of the crankhome-VR ('''134 BTDC cyl5''' in the original config) pulse '''should always see high'''; the other ('''62 BTDC cyl1 in the original config) should always see low voltage level''' => the 5-window HALL setup is just as good as the 1-window. Just make sure the crankhome is positioned close to the middle of the tooth (so even with some belt-sloppiness, it's surely there), and you're done * But '''with 60-2 primtrig you only need camHALL''', the crankhome is not needed (only 2 sensors total)
