Summary of change:
'''Project VW Passat VR6''' *Demo/Test Vehicle for VEMS V3.3 *VW VR6 6 cylinder engine *Firing order 1-5-3-6-2-4 *Sequential fuel injection *60-2 VR crank trigger *1 Window hall cam trigger *NTC temp sensors *Standard TPS *2 OEM knock sensors *High-Z injectors *3X double ended waste spark coil with ignitor *2 wire PWM Bosch Idle Valve (min/closed duty ~25%) **Bosch #0 280 140 512/ VW #034 133 455B,2 wire, 8.2 Ohms (~1.5A) * '''Can 2 stepper Outputs be combined to handle 2 amps?''' ** there is no official way for this. ** if used as ignition outputs, ign_dualout would work, but connecting 2 stepper outputs directly would most likely blow it _very_ soon (depending on config) ** if you only need 1-side (like pull up, or pull down) driver, it is easy to use 2 diodes to make it a higher current output. This is safe. However, driving them simultaneously ... not supported (except for ignition, with the ign_dualout). ---- '''MSQ File:''' http://www.vems.hu/files/KevinBlack/Lugnuts2.msq ---- '''TODO:''' *Scope Idle valve,Tach signal,Injectors,Ignition '''DONE''' **Idle 100hz,4.4ms at idle (44%DC) **Tach +10.8v, 66% DC "on", 3 tach signals per rev **Injection pulsewidth: 3.2ms warm **Ignition: 4.8ms dwell at idle, 13.8vbatt *Measure resistance curve of temp sensors *Install and configure v3.3 board ---- '''Current Order:''' * 1-wire interface: NO * Ignition driver: 4+4 * Knock and EGT: Yes (2 knock,1 EGT) * LCD and PS2: Yes * MAP connection: Onboard 400 kpa) * Power Flyback: 30v bidr * Primary_trigger: VR (60-2 wheel) * Secondary_trigger: HALL (one window) * Lower (than 510 Ohm) resistors for i259 logiclevel outputs for use with VAG 1.8T COPs * OEM Bosch temp sensors '''Build notes:''' *Board_version=v3.3 *Serial_nr= 857 *pump-= 4.14V *wbo2_pump_pw_zero=0x67 *pump+= 4.14V *(C103=1nF, no D100) ----
Optional: Add document to category:
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.
