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.
Planned 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)
- Exhaust Gas Temperature sensor (EGT)
- K Type
- Throttle Position Sensor (TPS)
- From automatic Corrado
- Intake Air Temperature (IAT)
- What else?
Ignition and Injection Setup
- Crank trigger from ABA code motor
- VR / HALL
- VR std 60-2 VAG wheel on the crank? Toothcount ? (position? - if you know)
- VR / HALL
- Wasted Spark Ignition (there will be no cam position sensor, only crank position)
- 4 output coilpack from 99 2.0 8v VW (this way I can use my stock plug wires)
- Sequential Fuel Injection (apparently it's an easy change toggling batch -> sequential, as long as you have the injectors wired separately)
CURRENT STATUS
Wiring!
Current wiring notes (note, connector names from bentley manual):
T2f (black connector by master cyl) R/Y should be fed to VEMS FP output
T2f (black connector by master cyl) R/W should be fed to O2 sensor heater AND fuel injector power supply (unless another source is found)
T3d (white connector by master cyl) black should feed VEMS +12v
