Has anyone read the article on electronic ignition in this months (july) classics monthly?
And I know this was covered before, but has anybody tried this companys newtronic electronic ignition systems before or the flame thrower coil?
Are they that easy to fit?
Would it cure pinking?

Pinking is caused by incorrect ignition timing which has to be precisely set with or without electronic ignition.
Electronic ignition compensates for worn distributors and avoids constant resetting and renewal of points and condensers.
A properly set up standard points system is more than adequate and electronic ignition is a waste of money.
Sort out your timing first the optimum setting is 6 deg BTDC set up with a strobe and 5 Star fuel.
For unleaded 95 Octane you should try retarding a degree at a time until TDC - every engine is different mine is best at 3 deg BTDC and show stable idle (650rpm) and max vacuum even in Drive.
Avoid driving with it pinking it will caused irreversible damge to pistons and heads

Hi Andy I don't have that magazine yet and you give no brand for the electronic ignition but the Flame thrower coil is marketed in the USA as a pertronix unit and I believe they are manufactured in the USA and UK. I did some research and fitted it over the luminitation mainly as people here in New Zealand said there were some reliability issues with luminitation and I liked the fact that the Pertronix unit fits completely in side the distributor. I did a post here a couple of months ago now. The unit has been fitted for about 20 months now and has been completely reliable. roverp5.proboards31.com/index.cgi?board=Rover33&action=display&thread=1113220276I do believe the units are sold under different names in different parts of the world but Pertronix seems to be the main name and company web site is on my earlier post. Also the unit for my p5b didn't exist in an Igniter II and they had the first one made for me ( apparently at their UK plant. Made is a bit of a grandiose term, they fit the electronics to a base plate so it just slots in on original points fixings) I have the kit numbers but now it should be a part of there product range. And a couple of members here have ordered them from my contact name there and information. You can see the number on the top of the unit - but check as mine was made up for me. Regards

Hi Phil Had the car tuned, runs OK under normal circumstances, but pinks under hard acceleration?

It sounds like too much ignition advance. Alternatively the vac advance unit or bob weights could be sticking in the distributor.
What advance setting has it been set at? If its at the standard 6 deg this is too mch for lower octane fuel. Ask the tuner and then try retarding a degree or so.
I found some petrols more prone to pinking than others eg Jet
It should not be allowed to pink under load as it will cause engine damage eventually.
You could try treating to tank full of Super Unleaded or add an octane booster.
As I said every V8 engine is different the setting for one engine may not be the one for another

Thanks for the reply Phil, I use super un-leaded with the castrol super octane booster additive, so will have to try and mess around with the dizzy.

Even Super unleaded is only 97 Octane well below the 100 octane the 6 deg ignition setting is for so there should be no pinking at all if you retard to say 4 deg BTDC as a starter. I use neat 95 with 3 deg BTDC
