Its more of a problem with after market ECU`s ,if i remove the resisted plug extenders 8ohms the plugs need to be resistive ..

I`ve had my Megasquirt looked at on datalogs and to date no spikes interference etc.
When I ditched my extenders I fitted a set of BPR6EIX iridium plugs.

IMHO they are a much better plug for this engine giving no more fouling, no radio interference, better idle, better cold start performance, better throttle response and they only need replacing every 50,000 miles so work out cheaper in the long run.

Finally they give no issues with an after market ECU installation, like my new Canems system biggrin

It's been quiet cos I'm just back from giving the old Lucas system it's last run by romping to Le Mans & back.

The old girl did good, apart from some French monsoon water finding it's way under the dizzy cap rolleyes

Boy did it pish with rain yikes

Five miles outside Le Mans & cough-cough-hiccup-splutter-recover-splutter-cough-recover ect ect for three miles yuck

Shortly followed by a full and complete recovery biggrin

The Canems is currently work in progress Simon smash

Full review to follow in a few weeks following extensive continental testing driving

Fingers crossed it won't end in tears cry

The Lloyd brothers have two proven 300HP 4.0 litres under their belt both running Canems, so confidence is strong wink

These are cheap enough worth a punt at £20

Not often I agree with Daz but he's right - those boots are no damn good for running without extenders - I know - I have those on my car and I've had several leads cook inside them already. Stick with the extenders!

I have seen some higher temperature versions of those available and I'm thinking of trying those but I'll still be sticking with the extenders...

Phil, then your using the wrong leads confused you still need high temp boots rolleyes and no not the old st we have over here but this type of thing, these also have the bendy ends that are designed to be permanently angled away from the heat source too biggrin this was my reason for choosing them over the competition cool Accel BB Chevy suppressed 9mm leads and about £45 to the door from the USA I would of preferred them in blue but you cant have everything whistle

Hmmm ... OK - might have to take a look at those but it was teh leads themselves that cooked and not the boots.

Also thinking of taking a look at a set of these...

http://www.ebay.co.uk/itm/Vulcan-Lava-Protector-Sl...

...as they're rated to 2000 deg F continuous (rather than 1,200 deg F) and 3,000 deg F intermittent...

Hi Phil they are my one's biggrin done me homework on this stuff some time back here you go to scale the product. I have big hands if that helps hehe this pic is about 18 mths old so hence the price difference.

I likes the look of thems leads Simon lick

My Magnecore KV85 leads seem to be incredibly heat resistant, before the glass woven socks I found one resting on the manifold, amazingly it didn't even mark it yikes

Personally I don't even think the Magnecores need the glass woven socks, but I did my normal belt & braces thing & popped them on for a bit of extra protection.

What ever type of silicone the red Magnecores are made from it's very unnatural, it seems counter-intuitive that this material can take so much heat.

But take it, it does.

What I'll get from the Chuckle Brothers on the Canems has not been fully clarified, but I did say I'm not a huge fan of extenders if decent leads are used.

I'd like to think they can cut & crimp my Magnecores to suit the ford coil packs?

Years ago I used to make up leads with a proper HT crimping kit.

Do people still do this?

Simon, can my Magnecores be used mate? ears

You should stop agreeing with me ! we might become friends laugh

I have these leads ,don`t know the make but there pretty good

Can you read "need help" post ? made a balls up..crossed leads.

[/quote]Yes they can, my 1st set i made up using my old RV8 dizzy HT leads, the Chevy leads as you can imagine had to have st loads cut of to suit the baby Rover 8 laugh i just crimped s/hand Ford OE ends (Motorcraft are the best quality) onto these to suit my coil packs & managing to squeeze these fat leads into the original 7mm coil ends/gaiters using silicone spray nerd although it depends where the Lloyds mount the coil packs scratchchin but they probably use this kind of crowd for that http://www.formulapower.com/ I notice they do their own thermal socks too wink

Thanks Simon.

Right, I'll give em a bell in the morrow.

I like my Magnecore leads, they've been good to me & I'd like to think they can stay.

Booties and all tongue out

Don't let them touch the manifolds then rolleyes it tells you that in the literature tongue out ...... wink although the O/S rear No 8 is quite close though whistle but don't touch.

Try downloading the CANEMS installation manual from Lloyd Specialist Developments website (from the product information page for the 14CUX Engine Management kit) - that may help?

Well, on my car they made a huge difference.

I have never fitted a set of new plugs to a car and seen such a dramatic improvement.

I should point out I moved from the original shrouded electrode (non projected) type NGK B7ECS like this.



To projected electrode type NGK BPR6EIX iridium plugs like this.



While there are longevity benefits in moving to iridium plugs I think the main advantage is that the electrode is projected, placing the spark further into the combustion chamber has to be better.

To this end I expect you'll see similar benefits if you just fit a set of NGK BPR6ES like this.



It's worth noting that many of the Rover V8 engine specialist recommend moving away from the shrouded NGK B7ECS to a projected electrode plug like a NGK BPR6ES.

I chose to go from the original 7 heat range to a hotter 6 as it seemed the 7's were fouling slightly.

Going back to the benefits of iridium, not only will they last longer but they should provide a stronger spark as experienced by the LPG running Land Rover guys.

You need a really good spark for LPG, so after reading some positive reviews on the Land Rover & LPG forums I figured I would give the NGK BPR6EIX iridium plugs a go.

What I found was the following immediate benefits:
  • Better idle
  • Better throttle response
  • Improved cold start performance
The engine generally ran significantly better in all respects, it simply felt stronger and more responsive on the throttle pedal.

I for one will never return to those prone to fouling shrouded electrode (non projected) type NGK B7ECS.
