So the question is does the new Distributor technology improve on the old?


Hope to hear more comments. Friend with XKE loves it, also for the security.
Born, and brought home from the hospital (no seat belt (wtf)) in a baby!
Find out where the limits are, and start from there

Peter


I've been using a red Bosch "performance" coil (1.8 Ohms, supposedly 33000V spark - no ballast) since installation 5-6 years ago, no issue so far (I understand if you go below 1.8 Ohm you may pullm too much current and risk damaging the circuit)

Thanks I will stick with the 3 ohm one for now.

Needless to say my install has not gone to plan so giving up for the night and will resume tomorrow. I plan to use the Escort curve but would like to check I have understood the install instructions correctly. In order to set the 123 dizzy in the correct position using the green light, should the engine be positioned at TDC or 12 BTDC?

Thanks in advance.

I prefer to set it to zero TDC , so that the programmed curved is the actual ignition curve (but you also could set it 12 btdc of whatever and deduce that from your programmed curve to the same effect)

That’s great. I thought TDC would be fine so will stick with that. The main thing is I can now rule this out as a reason for the no start. I will have another go tomorrow and hopefully the engine will start.
I installed a 123 on my old Mercedes a few years back and the car started on the first turn of the key. I wish things were like that when I mess with the Plus 2.

Dizzy was 180degrees + a spline or two out. All running fine using the Escort curve for the time being.

Thanks for the help and info.

Peter, good to hear that you are sorted. :)

I also found the Escort Curve to be more suitable to date, but I am also sure that when my engine is run in, it will be possible to increase the advance above the 26 degrees at 2400RPM it’s currently set at. Note this being for a Road car.
