---- '''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 v3.2 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) ---- 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 '''EGO Correction''' I've enabled EGO correction to compensate for a rough VE table. This is the easiest method until I can get someone to drive the car while i learn how to adjust the VE table on the fly. It seems that EGO correction is not being turned on consistently and I don't know how to interpret what I see. What I feel is the EGO messing with small part throttle situations causing the car to hesitate. At full throttle conditions I don't think correction is being used. Feedback is appreciated.

Lost a vacuum plug which increased the idle. This exposed an issue caused by fuel cut and fuel resume being too close together I am having an idle issue. PW is hitting 0 at idle at semi-regular intervals. Look 71 seconds into the log file to see.
