trollin information is just a waste of time , show us some pix or something of what YOU are doing, talk is cheap!
like you said old tech is OLD , OK fine so you dont need our help, do something nobody has ever done!
ron
maybe we can have an Old Fashioned Street race , FULL moon is comin up! LOL.

Besides. Now when I have this information I will digest it, I wouldn't say it was wasted. I shelved this project, true. But I didn't cancel it. I'm kind of perfectionist. Now I see to keep this affordable I need to compromise. I need to do a research on COP's and their parameters. The moment I find an affordable COP that can run 15k RPM in a four-stroke my project will go alive again.

710 Series ECU this maybe?
Don't forget there is also a BMW V12 engine from the same 'era' maybe there are aftermarket solutions for that which can be transplanted into an XJS?

Anyhow, there is light at the end of the tunnel.
MegaSquirt with 12 cylinder discrete spark.

More information for those interested, I hope ronbros does not mind?
Toyota 1ZZ COP's are reported to run at this frequency, so they can be used with wasted spark in our V-12.
The 1ZZ engine was equipped in various automobiles:
Toyota Allion
Toyota Avensis
Toyota Caldina
Toyota Celica GT
Toyota Corolla
Toyota Isis
Toyota Matrix XR
Toyota MR2 Spyder
Toyota Opa
Toyota Premio
Toyota RAV4
Toyota Wish
Chevy Prizm
Pontiac Vibe
Lotus Elise

This is due to way a dual plug coil works. Electrons move from one plug thru the coil to the second plug. If plugs are designed for certain polarity - like these "grooved NGK's" - then the electrons move the wrong way in one of plugs and there is nothing you can do about it. You may consider this a minor issue, but it still is an issue.

All I know is the Ford system work and works well. It meets emissions and gives a very nice spark, so who am I to second guess the Engineers who knew what they were doing?

Well, then have a closer look. Single plug coil has one end of secondary coil (high voltage) grounded inside of case. Dual plug coil has this end connected to the second plug. You need some sort of continuity tester for doing this simple test.
Edit: But indeed, it is not my job to teach people, so if you wish to believe there are two coils inside of one case so be it. Just for you.

The polarity is completely irrelevant -22kv or +22kv will produce exactly the same spark on the same plug.
Any ignition coil is 2 coils 1 primary and 1 secondary. The voltage increase is a direct relationship to the winding ratio. A Wasted spark coil is no different it is still 1 primary and 1 secondary with 2 plugs connected to the secondary,

True to a certain degree. The future is COP, and you still ignore the spark polarity issue with wasted spark.

I'm leaving this thread now, interacting with idiots in not my idea of having fun.

.
way back 1995, found at Walmart both the outside lights 5"LED i mounted them in the buckets(little tricky getting adjusted),but is OK much brighter than factory.
the inside are early projector beam great for low beam.
that was 25yrs ago,, if doing it today, definatly use much better lighting systems , but it can be done!
side note car is up for SALE. ron
try it you will like it!
