Summary of change:
'''1981 Volvo 242 DL''' http://oeb.xerc.biz/vems/DSC00020.jpg The car is a '81 2-door Volvo. My 'first' car, rebuilding it as a 'rallycar' for the streets. ---- Fabric new B21ET engine. http://oeb.xerc.biz/vems/IMG_0290.jpg * VEMS Genboard v3.3 (1.0.38) * Bosch 337cc/min 3 bar Low-Z injectors * Mitsubishi TD04-HL16T turbo * Honeywell 1GT101 crank trigger, no cam sync * Distributor ignition * Dana 30 1030 with 4.10 and LSD, Volvo M46, Helix rallycross-clutch * Volvo R-Sport DeCarbon yellow shocks. * Rollcage and Sparco seats '''Q&A:''' '''Q:''' also considering wasted spark ? '''A:''' No, I'm not considering wasted spark on this engine. '''Q:''' what is the tooth-pattern of the crankwheel ? '''A:''' Here is the trigger wheel http://stuff.oeb.no/forumpics/vems/triggerwheel.jpg '''Q:''' do you already have the injectors ? maybe you plan to upgrade to bigger injectors anyway ? what flyback solution do you have in mind ? do you have some [http://shop.vems.hu/catalog/index.php?cPath=1_7 Power resistors] or willing to solder 4x27 Ohm 5W in parallel (for each injector!) ? This way, with 30V transient flyback it would be much easier to tune (especially at idle) '''A:''' I do have power resistors, but I've ordered some 605cc high-z from racetronix. ---- '''Update 2007-05-31''' Trigger problems! Only while cranking, if I crank it just once the RPM jumps to ex. 100, 5000 rpm and so on. It stops when I reset the power to the VEMS. This would probably be a problem when the engine is running too. Any ideas? Yes, all the grounds are correct.. power and ground is drawn directly from the battery in the rear, 6mm2 cables. The strange thing is it only occurs after cranking, resetting the power solves it. Coil-type trigger, 1GT101, no filtering (see picture for triggerwheel - acid primer and black paint on the wheel, should'nt be a problem?) '''Update 2007-05-16''' Rollcage and chairs are now mounted. Engine bay was repainted under the winter. Fuel plumbing and harness awaiting. http://oeb.xerc.biz/vems/160507/inside.jpg http://oeb.xerc.biz/vems/160507/fuel.jpg http://oeb.xerc.biz/vems/160507/enginebay.jpg new tps adapter: http://oeb.xerc.biz/vems/160507/throttlebody_tps.jpg '''Update 2006-12-14''' Whole harness went out, again. Welding rollcage, Sparco seats on its way.
