25uF at 12v sounds very small to me to have any appreciable affect Martin, You're 100% right there, it's actually about the smallest value that will make sufficient difference to 'fix' the problems! It doesn't fully smooth out the voltage glitches on the LTD but it does _just_ prevent misfires. Jus...

Actually. it's not there for suppression purposes. It provides a voltage reserve function in some chassis variants where for various reasons the wiring exhibits a significant voltage drop on each spark event. Put a scope on the +V feed to the EDIS pack on a '97 V8 LTD and you'll see what they were '...

I'm running Megasquirt on a fuel injected Datsun 260z with EDIS (which I like for the simple robustness of the ignition side). When the 240K GT tarmac project got started I went looking for something that would provide ignition only as the plan called for a blown LPG (propane) L28 engine. A search o...

Well, I scratched the old head for a bit on this one from Dave999 and finally decided some of these old tales really need to be put out to pasture. 1. normal oils never did contain moly or for that matter any significant quantity of lithium. They were in greases, each for a specific use. 2. current ...

I believe the 53 degrees is 'all in' - ie intial plus centrifugal plus vacuum. For a relatively low performance engine as in a Land Rover I would consider that pretty normal and yes, the top right box is where you would find it. Be careful about those sort of advance figures on LPG though - a reason...

Depends on where you are referencing the BTDC angle :) More precisely, the sensor mounted in the distributor will be positioned at half the usual angle BUT .... you would check the true firing point against a reference pointer and a degree wheel (or tape) on the nose of the crankshaft. When checking...

I don't think there is any easy way of doing that unless someone wants to develop an equivalent for EDIS with CDI output.
Not a trivial task!

It does essentially the same job as MJLJ at a cosiderably higher price so why would you fit it WITH an MJLJ?

Nice to see that instinct & experience telling me that mixture bouncing of the back of the valves was the culprit but sorry that the cam was so bad. Just curious - are you using cam followers from the same manufacturer as the cam? Replace the followers as they will have copped a hiding from a ca...

If you're not afraid to use eBay then purchasing from USA is the best way. You don't have to use a Ford 6 cylinder coil pack, a Chrysler Voyager pack works at least as well. It doesn't need those stupid Ford designed plug leads either - towers on the pack are the same as GM and earlier electronic ig...

What is the mapping you are using? Another off-the-wall possibility is oil - you are using a 'normal' oil and not some heavy weight competition oil I hope. I've been caught with 'anti-pumpup' lifters and 60 weight oil - the lifters might as well have been solids at high revs! Contact Piper and ask f...

I assume the faults (air leaks, fuel pressure etc) identified by RichB have all been corrected? Can the engine be stalled on all four intakes now? Just ticking fingers: Tried alternate MJLJ system from RichB and new coilpack - no difference. Not likely to be ignition fault. Tried longer outside ram ...

I wouldn't worry too much about the occasional glitch in the firing of the ignition - it sure won't cause what your vid shows! Deal with that later. Have you tried longer intake trumpets? If so, what happened? In checking the cam timing, have you done so with a degree wheel (or tape) and dial indica...

Air leak is a possible cause of lean mixture although affecting both barrels of a Weber is a bit unusual. Test is easy - use a can of WD40 or similar water dispersant with a thin tube nozzle. Run the engine at 2000 or a bit more, squirt around manifold/head gasket, carb mounts, any blanked off fitti...

Umm, the problem didn't follow the carb so it's either both 1&2 related or both carbs are marginal and the front carb location just happens to be more problematic. A cylinder cranking pressure ('compression') test might reveal a problem common to both cylinders. A head gasket blown between cylin...
