Megasquirt and wasted spark

[golf3]

YO!

I've been reading up on megasquirt ECU's for my future plans, whether or not i go ITB's or turbo...

I have a distributor with a single coil. Is it worth swapping to a mk4 style setup with hall sensor, and coil pack???

I've seen photos from the mk3 homoglomated rally car which had this style setup, and a cool carbon fibre intake coming from the bottom of the windscreen. (being the highest pressure zone apparently)

So...who's going to help me get 200hp??

Quoted from another forum:

Name: Basil Daham
Vehicle: 1996 VW Golf GTI 16V 20th Anniversary
Engine: 1984cc, ABF engine code, 16 valve, P&P'ed head, 268 Schricks, free-flow filter & exhaust
Injection: Port injection, 225cc/min, Digifant 3.2 ECU, 60-2 trigger wheel, hall effect crank sensor, PWM 2-wire bosch idle valve, Bosch coolant and intake temp sensors, single coil with integrated module;
Description: The objective of this install was to use the original wiring loom. To do this, an old 68 pin ECU was cannibalised and turned into an adapter. The MS was installed inside the car, with wires running to the 'ECU' box. All the original sensors and actuators were used.

MS v2.2 mods included flipping the opto circuit input as used by the VW community, and as outlined in schematic 2 here. A TIP122 was installed to PWM control the 4 ohm idle stability valve. Bias resistors were replaced with 2.2k 1% ones to suit Bosch sensors.

Pin configuration:

MS GROUNDS (8,9,10,11) go to T68/1
MS SENSOR GROUND (19) goes to T68/33
MS MAT (20) goes to T68/36
MS CLT (21) goes to T68/14
MS TPS SIGNAL (22) goes to T68/40
MS O2 SENSOR SIGNAL (23) goes to T68/20
MS PIN 24 was fed a constant +12V internally using a jumper inside the megasquirt, and this was in turn fed to the hall sensor power (T68/68 )
MS XG1 (inside the MS box) was fed the crank sensor signal from T68/67 (using pin 25 on the DB37)
MS TPS Vref (26) goes to T68/41
MS coil control (27 in this case) goes to T68/8
MS +12V (28 ) goes to T68/38
MS FIDLE (30) goes to T68/27
MS INJ1 (32,33) goes to T68/24 and T68/25
MS INJ2 (34,35) goes to T68/26 and T68/2
MS FUEL PUMP (37) goes to T68/6

Options included:

Tacho out, (pin 29) was fed to T68/22
LAUNCH CONTROL on pin 31

Crank signal was decoded using MSnS-E 029n. 60-2 wheel, with 14th (15th if 0 and 1 are the missing teeth) tooth at TDC. Trigger angle 60*. Trigger position A was 5, Trig pos B 35, Trig return pos A 14, Trig return pos B 44. Spark output was INVERTED since the VW module goes from 0 to 5V when it wants to trigger the coil. Dwell measured with a scope was 4.5ms for the ABF ECU. Using 3ms on the MS for now.

Will post VEX/MSQ's when car is properly tuned.

Vr6's run wasted spark, and im pretty sure that coil pack 4cyl's run it too.

In regards to what yoou need to get the power, I think asking Valver would be your first stop. How much power did his Ibiza make again? think it was well over 200 on ITB's.
