Okay. Not terribly hard to do, but you do want to be careful doing it, in case you over do it and get pinging etc. Its also a bit of a bitch in that until you wind it back, you need to keep putting in premium (which bites when you get stuck at premium is at $1.10 a litre
).
Anyway, enough of my whining :)
Basically, you need a timing light, and a bit of wire with some alligator clips or very small spade sockets on it, and a spanner (to loosen/tighten dizzy).
General strategy is:
1. Warm up car to operating temp.
2. Turn off car
3. Connect "Self Test" pins on diagnostic connector (in fuse panel near steering wheel)
4. Start car - it should lift its idle to 1300-1600 rpm. At this point it should have removed any spark advance, and ideally be running at 30btdc.
5. Go crazy with the timing light and spanner to adjust the dizzy.
Suggestion is to check that you can see the timing marks *before* you warm the car, and clean / mark them better if needed ( chalk can be handy ). You might need to turn over the motor by hand to find the marks. To set the diagnostic mode / self test, you need to link the two left-most pins in the diagnostic panel (ie left most on top row, and leftmost on bottom row).
e.g
X--------

With X being the linked pins. There should be a pic and explanation on
www.fordmods.com about this as well (look for Diagnostics - EF - EEC-V info).

Re: Advancing timing
where was the power before!!!! Really strong pull in the low to mid revs. I haven't dyno tuned yet, but it feels better, maybe 3-5 rwkws by the arse-o-meter.
If the car hadnt been tuned I reckon it would have been a hell of a lot closer, possible him beating me. I was really surprised at the outcome and how extra responsive the car had become.
