My name is Paal, working and playing with toy cars in Bergen, Norway.
Time to update progress in 2009....
The goal
Apply a GenBoard/VerThree (V3.3) to my Polizei-golf's new engine.
The car:
The engine:
- 16v KR engine with S2 pistons
- S2 intake manifold with S2 TB throttlebody [TPS schematic]
- K24 turbo
- 440cc (high impedance) injectors and 3,5 bar FPR
- 034EFI idle stepper motor [link]
- 034EFI wasted spark coil [link]
- 034EFI IAT sensor [link]
- OEM "blue" water temp sensor
- Walbro fuel pump (original G60 fuel pump not sufficient)

VAG 60-2 (BOSCH) Hall trigger:

German thread: http://www.golf1.info/forum/thread.php?threadid=14109&page=2#post151865 and [ELSAWIN screenshot here stating it is a Hall sensor, (ro/gn) goes to G40 pin#1 (which we know is Hall), and EGR-potentiometer pin#2 (reference voltage) (TeroK)])

- 85° BTDC with cyl1 at TDC [reference]

- OEM parts numbers:
- sealing flange with 60-2 trigger wheel and plastic clip to align wheel with housing: 030103171L (~65 EUR)
- Hall sensor with ~15 cm wire: 030906433Q (~40 EUR)
- Steel backing plate: 030103647E (~20 EUR) - some modifications, see vortex thread.
- [Vwvortex thread part numbers for hall sensor connector, wires and rubber grommets]
trigger settings example from emil (2008):
- Falling, Multitooth
- with trigger tooth 3
- TDC After the trigger = 62 degrees
- is this measured or speculation ? verified via strobing ?
- it's easy to get into the ballpark (+-6 crankdeg) with InputTrigger/TriggerLog, but it's really a good idea to verify via strobing anyway
VEMS specifications
Hardware:
GenBoard/VerThree V3.3
Assembled v3.3 controller
- Options to be decided this week.
Todo:
- Figure out how to get TACH signal (MembersPage/SteinOvePrestmo did this?)
- Control boost with what? Suitable part from webshop?
Progress 2009
- Engine is in car
- Pipeworks, welding intake / downpipe is soon done
- Ordering VEMS unit + sensors + harness this week
