---- '''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''' I have lean spots as the car crosses into positive pressure. If you notice, in MegaLogViewer, the Accel flag swithces from Y to N right as it crosses the 100-105kPa area, then back to Y again.
