Summary of change:
'''Jonas Olhssons BMW 1602''' http://www.vems.hu/files/MembersPage/MattiasSandgren/BmwJonasMtenTurbo/jonas_blackrace_20040703.jpg ---- '''News''' '''2007-08-03''' Engine has been started, we had to add the R30 pull-up resistor because it was not mounted (I assembled and built this system myself) but after that the trigger worked. MAP is steady, about 85 kPa @ 1500 rpm idle. As expected this engine needs lambda 0.85 (or at least below 0.90) to idle properly. This engine could _really_ use '''mappable fuel injection angle''' to get a reasonable idle and low load quality, or at least development should be pushed towards Alpha-N with pressure compensation. The engine was only warmed up today and an oil pressure problem appeared that must be resolved before any more is learned. ---- '''Engine specification''' * BMW M10, 2.0 litre crank, stock rods and Mahle forged pistons * Schrick cam shaft (300+ degrees duration) * Individual Throttle Bodies * Ford Motorsport 1600 cc fuel injectors, 5 Ohm impedance ** Run in saturated mode with no power resistors and a 30 V TS diode on the flyback wire * Stock distributor with heavy duty coil and MSD 6A CDI box * Honeywell GT1 Hall-sensor on crank (and eventually cam) ---- * ''I am interested to see how you do with the 1600cc injectors, when you have it running good I'd like to see the injector settings if you wish to share. I have a subpage for injector settings here'': MembersPage/KevinBlack/InjectorSpecDatabase ** I will share the settings, but the parameters are _very_ hard to find since the VEMS firmware currently lacks the vital timed fuel injection function. Without that it is not possible to get good enough idle quality to get repeateable and discernable results. We will not focus much time to get good idle quality on this engine due to this.

Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
