---- '''Navigation''' * Main MembersPage/KoabiBrooks * Idle MembersPage/KoabiBrooks/Idle * Ignition MembersPage/KoabiBrooks/Ignition * Injection MembersPage/KoabiBrooks/Injection * Trigger MembersPage/KoabiBrooks/Trigger * Wiring MembersPage/KoabiBrooks/Wiring * Q&A MembersPage/KoabiBrooks/Questions ---- '''Current Status''' Tuning for larger injectors on e85. Added the TS diode after having trouble getting the car to run with the larger injectors. Idle stabilizer added as well. Initially the car idled well, but then after a small drive, the idle was jumping up and down. MSQ and Log below: MSQ: http://koabi.lazyslacker.com/VEMS/logs/63lbinjISV01working.msq Datalog: http://koabi.lazyslacker.com/VEMS/logs/63lbinjISV01working.xls Some general info on E85 as well as future possibilities: http://www.megamanual.com/flexfuel.htm Old 91 octane tunes below: Config: http://koabi.lazyslacker.com/VEMS/logs/20071201config.txt Tables: http://koabi.lazyslacker.com/VEMS/logs/20071201tables.txt MSQ: http://koabi.lazyslacker.com/VEMS/logs/20071201megasquirt.msq Datalog: http://koabi.lazyslacker.com/VEMS/logs/20071201datalog.xls ---- '''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''' *1988 Volkswagen Scirocco 16v *Suspension **H&R coilovers **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 **63# high z injectors **Adjustable fuel pressure regulator (set to 4 bar) *Transmission **020 with shim kit, bolt kit, still a timebomb ---- '''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) ---- The ECU (which apparently is a v3.2 board has this mod using 0 ohm connections): http://koabi.lazyslacker.com/gallery2/d/18267-1/genboard32AREF.JPG ---- '''Useful Resources''' Crank wheel trigger generator: http://koabi.lazyslacker.com/VEMS/cranktriggers.php GrmRacer's install guide (note injector flyback is accidentally omitted from the pinout) FIX THIS LINK: http://www.starshadow.com/~koabi/carstuff/VEMS/Information%20to%20setup%20your%20VEMSv3.htm ----
