Current Status
Hooking up idle stabilizer valve. Please see the new idle section for details.
Running E85 fuel, but the car's duty cycle was very high, so new tunes will appear when I have more safety margin (bigger injectors, more fuel pressure).
Some general info on E85 as well as future possibilities: http://www.megamanual.com/flexfuel.htm
Old 91 octane tunes below:

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
- 48# high z injectors (correct if wrong - high z meaning constant voltage to open is what I am assuming)
- 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
- Intake Air Temperature (IAT)
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
- VR std 60-2 VAG wheel on ABA crank. Those using different blocks may have to use external setups. See MembersPage/DerrickScirocco
- 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
- 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)
- 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):
