---- '''Navigation''' * Main MembersPage/KoabiBrooks * Ignition MembersPage/KoabiBrooks/Ignition * Injection MembersPage/KoabiBrooks/Injection * Trigger MembersPage/KoabiBrooks/Trigger * Wiring MembersPage/KoabiBrooks/Wiring * Q&A MembersPage/KoabiBrooks/Questions ---- '''MAIN PAGE''' http://www.starshadow.com/~koabi/photos/sciroccoproject/051224sciroccoengine.jpg I have an '88 Volkswagen Scirocco '''My goals''' *To have control over engine management *Make car reliable (near stock levels?) *Learn about what makes all these variables work together *NOT TO BLOW UP THE MOTOR '''Car Specs''' *Suspension **Eibach Sportline Springs **Tokico Shocks and Struts (for now) **Poly bushings *Engine **ABA 2.0l 4 cylinder motor (From OBDI Jetta or Golf) **PL 16v head (From 1.8l 16v Scirocco) **Thottlebody with TPS (From automatic Corrado - bolts on) **Turbo T3 .60/.48 (From ~'84 Ford Thunderbird) **Gillis boost controller (Manual screw type) **Intercooler **Fuel Injection from G60 Corrado (CURRENTLY) **48# high z injectors (correct if wrong - high z meaning constant voltage to open is what I am assuming) *Transmission **Stock time-bomb ---- '''VEMS SETUP''' I am going with v3.3 assembled. Here is the current plans, which are subject to many, many changes. '''Components''' *Sensors **Intake Air Temperature (IAT) ***GM #25036751 **Manifold Absolute Pressure Sensor (MAP) ***2.5 bar (on board ECM) **1 Wideband oxygen sensor (WB02) ***Bosch LSU4 **1 knock sensor (engine can accept 2, so perhaps I will eventually use 2) - ''not yet implemented'' **Exhaust Gas Temperature sensor (EGT) - ''not yet implemented'' ***K Type **Throttle Position Sensor (TPS) ***From automatic Corrado **Fuel Pressure Sender - ''not yet implemented'' ***Probably the one at the VEMS webstore **Boost Controller - ''not yet implemented'' ***Also through the VEMS webstore '''Ignition and Injection Setup''' *Crank trigger from ABA code motor - I won't be using a Hall ** VR std 60-2 VAG wheel on ABA crank. Those using different blocks may have to use external setups. See MembersPage/DerrickScirocco ***Part # 021 907 319 B *Wasted Spark Ignition **4 output coilpack from 99 2.0 8v VW - new beetle for sure, AEG engine code (this way I can use my stock plug wires) ***Part # 032 905 106 B *Sequential Fuel Injection (apparently it's an easy change toggling batch -> sequential, as long as you have the injectors wired separately) ---- '''CURRENT STATUS''' Rewiring after killing an injector wire due to poor wiring The ECU (which apparently is a v3.2 board has this mod using 0 ohm connections): http://www.starshadow.com/~koabi/carstuff/VEMS/genboard32AREF.JPG Current WBo2 config: nernstdc 0x85 pump_pw_zero 0x66 wbo2_calibration F9 ---- '''Useful Resources''' Crank wheel trigger generator: http://www.starshadow.com/~koabi/carstuff/cranktriggers.php GrmRacer's install guide (note injector flyback is accidentally omitted from the pinout): http://www.starshadow.com/~koabi/carstuff/VEMS/Information%20to%20setup%20your%20VEMSv3.htm ---- '''Comments''' Updated firmware to 1.0.53 *I can't get the ALS SW indicator to be switched off in MT. The car drives normally, so all seems to be well, but it would be nice to have the indicator off. ** Try to set "Input Channel used" to "old: SDA" under ALS-settings. The channels 0-7 consider 0V as on and +5V as off, that's why they need a pullup-resistor to +5V. * Also I am having weird accel enrichment. config: http://www.starshadow.com/~koabi/carstuff/VEMS/configs/20060925NOALSconfig.txt tables: http://www.starshadow.com/~koabi/carstuff/VEMS/configs/20060925NOALStables.txt log: http://www.starshadow.com/~koabi/carstuff/VEMS/logs/datalog200609252124.xls
