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.

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.

Good morning all,

I am in need of a distributor for my newly rebuilt engine ( if you have read another recent post of mine you will understand why) The engine will not be used for competition so cannot justify the cost of a 123 unit, but still wish to get something which is correct for the car. I have discovered Ignition car parts in the UK

https://www.ignitioncarparts.co.uk/Cont ... ntact%20Us

who will build a new electronic distributor, complete with cap, mapped to any advance you wish for under £100. I realise the whole topic of advance curves is a minefield, and even respected books like the Miles WIlkins bible have incorrect data, while other distributors sold for the twin cam engine are just wrong. Consequently I am considering sending Ignition Car Parts "2cams" advance curve, which looks to work well, and asking them to build me a distributor.

Is anything wrong with this strategy. It seams too obvious (and cheap!)

Thanks in advance for any comments.

David

A distributor is a pretty basic thing, a handful of moving parts, and that's about it. There are sellers on eBay offering 23D4 clones with electronic ignition module for less than £90.

Having said that, you want a distributor with a known repeatable advance curve, innards that fit well so you don't get ignition scatter as they wobble about, a rotor arm and distributor cap that don't short out when they got hot and an ignition module that won't leave you by the side of the road.

I learnt my lesson the hard way after a sequence of failures, and following advice I received from posters here on lotuselan.net, started using the 'Distributor Doctor'. Great service, and good quality, reliable parts.

Ignitioncarparts may well be the same, but I would want to get a few testimonies from satisfied customers before I risked it.
