Greetings from Finland!
My project car is Ford Escort Mk4 -87
Plans to season 2011: Install VEMS and throttle bodies
On July 2010 I got it to the dragstrip and results are: ET 14,32 s and speed 158,73 km/h
On August 2010 we got it to the dyno and results are: 129,9 Kw and 231,3 Nm.
Engine:
- Ford Galaxy -99 2.3i 16V engine block and cylinder head
- Ford Escort RS2000 -92 cams, exhaust header and intake manifold
- Ford Escort Cosworth T25 fuel pressure regulator (3,5bar)
- Davies Craig electric water pump and controller
- Ford Escort RS2000 ECU (EEC-IV) with Collins chip and EDIS4 with dual coils
My VEMS history :)
I build one VEMS project in 2008, but I sold it forward because I didn't have time to tune it. So it's time to try again!
Old wiring harness and ECU:
VEMS external hardware
Injectors: Bosch 0 280 155 504 (~280cc/min@3,5bar?)
Coils: Ford dual coils
Coolant sensor: maybe GM because resistance range is suitable and it's got correct thread
Intake air sensor: GM for same reason
Primary trigger: Ford VR sensor
Secondary trigger: Ford VR sensor, reading exhaust cam at cylinder 4 (I'm not sure do I use this at the beginning at all)
TPS: Keihin TPS (stock Suzuki GSXR1000 K2)
LCD: 20x4 black/green with inverted colors
Lambda: Bosch 057

Questions and answers
1. I want to be sure with primary trigger config. So, when using 100% same triggering that Ford EDIS use, what are correct settings? EDIS4 = missing tooth is 90 degrees before VR sensor when first cylinder is in TDC. Trigger wheel is solid mounted to crankshaft and VR sensor is solid mounted to block.
Is it same as in this page http://www.vems.hu/wiki/index.php?page=InputTrigger%2FMultitoothTriggerWheel ?
- TDC of cyl1 (and cyl4) comes
- 83 degrees after the point, when
- the first tooth after the missing tooth just passes the trigger (considering the rotational direction).
- that is 8 tooth and a little on the 36-1 wheel.
- we place trigger_tooth to 20 degrees (02 teeth)
- so 63 degrees remains for ign_tdcdelay
- so the sum is 83 degrees
2. What best suitable firmware to my project? Just put latest version and that's it?
4cyl, 36-1 VR trigger, n/a ITB, wasted spark
