Last week i was on here reading a thread here which gave instructions on how to do the 14 degree ignition timing modification.

Ive been on here for ages this morning and cant find the thread, could anyone post instructions or a linkto the thread?

Ive got a mk1 1.8 and realise the difference may not be very noticable but think its worth doing as it doesnt sound too difficult.

Thanks in advance!

Don't remember what thread this was on now, but don't worry I saved it.

It said:

"The stock timing is around 10 degrees. This is so it can run happily on any rubbish petrol, anywhere in the world. By advancing the timing to 14 degrees, you are optimising the engine to the higher-octane petrol we have in this country. This will give you a few more peak horsepower (reputedly around 10) and move the peak torque lower down the rev range. I myself had mine set to 18 degrees and ran on super unleaded. The midrange torque was definitely improved at the expense of a little peak hp. Well worth doing and only takes a few minutes with a spanner and timing light.
1. Make sure plugs are new or at least clean and gapped correctly.
2. Link the ground and ten sockets in the diagnostics plug with a short piece of cable.
3. Adjust the idle speed to 800 rpm with the air valve screw on the throttle body.
4. Slacken the 12mm bolt to adjust the cam sensor on the back of the head.
5. Move the sensor until you get 14 degrees showing with the timing light.
6. Tighten the cam sensor bolt and remove the link.
7. Go for a drive & enjoy!"

Not 10bhp!
It gains a bit of torque in the midrange which makes the car feel a bit quicker. It's not a massive difference but as it's free it's well worth doing anyway wink

But does this mean less at the top end? I don't think the car can afford to any of its horses at all...

I don't believe you do lose anything at the top end but top end is only for bragging rights anyway. Advancing the timing gives you more torque where you really need it. Trust me, it will feel quicker with advanced timing.
