Installing and Setting Up 123 Ignition Tune+ on a Jaguar XK Engine

After some troubleshooting in the previous video we determined that my daily driver Jaguar XJ6 has an ignition related misfire. Good news! Now I have a very good reason to upgrade to a new 123 Ignition Tune+ bluetooth distributor. In this video I show in detail installing and setting up 123 ignition Tune+ on a Jaguar XK engine.

It's been a few days since this was filmed and I have now driven the car more. I have made a few changes to the map and I’ll be sharing that in the future. It runs fantasic with really good throttle response. Pulls very cleanly all the way to 5,000 RPM (I don't want to push it more) So far it's a really good product!

[@donbryan5551]

It’s also great to be able to share curves and maps👍🏾

[@BrianMadsen-yj8df]

Hi Adam, where did you find the formulas for the various curves? I just got my 123 Distributor after watching this video and would like to set it up properly. Thanks!!

[@LivingWithAClassic]

@BrianMadsen-yj8df I worked them out myself. I took the curve from a series 1 distributor and modified it. You can find the curves for the original distributors if you google them.

[@johndavey72]

Hi Adam. That engine really did sound like a bag of nails ! I sussed the microphone was the culprit . Your knowledge is breathtaking , you lost me and probably the majority of viewers completely with your very detailed explanation ! Thanks Adam.

[@aaronjones1044]

yes!! didnt know this existed. only was aware of mods with megasquirt.

[@LivingWithAClassic]

It’s a very cool upgrade

[@kentandersson457]

I had 123 ignition fitted to my Mk 2 3.8l 1964 this spring. Got a whole new car, smooth and nice running, all horsepower has found its way back to the engine 👍👍. Best investment.

[@LivingWithAClassic]

So far it’s a great upgrade here too!

[@springy-2112]

Glad to hear it's running better now . Peace and love brother ✌️ ❤️

[@LivingWithAClassic]

Thank you!

[@martinnicholas9867]

Hi adam ,this is very interesting this 123 dizxy set up,like that .Being able to ajust timing sitting in the car on the fly. In some way it"s condunrim that they run so well with a new point's dizzy. It the 123 seem's to be a cheaper way to big tuning. Rather than a full ecu.

[@donbryan5551]

I am using a 123 distributor on a 1968 4.2L etype. My curve is different than yours with 0 degrees below 1000 rpm. The car starts and idles beautifully. This is the best upgrade I have made to the car. Once you have the timing correct, It’s great to know if there are any performance issues then it’s probably fuel related. I am going to try your map because it’s so easy to do.

[@mariosnikolaou5212]

M8, it's been a long time since you uploaded a really interesting video and this is definitely one of them, I don't want to discourage you, make it's the reason I don't still have my XJ6 , but this video was absolutely marvelous and i would like to see the tuning process in the future.Cheers from Greece. P.S.Also i though that maybe you would be interested in my XJ6 Series 2 which has 60K original kilometes, and is the same colour as your's.

[@kevinhaigh1654]

Really interesting video today fella enjoyed it so much excellent

[@LivingWithAClassic]

Glad you liked it!

@@LivingWithAClassic thought it was amazing, amazing technology honestly

[@bespokeaddict]

Fantastic my friend, I have been planning distributor upgrade on Beelzebub_the_jag when I eventually come to end of marathon bodywork restoration, initially, this looks amazing, I'm excited to see how you get on with 123 in coming months.

[@LivingWithAClassic]

So far it’s really good! The real test will be the next couple of months

[@jaguarrroman]

Great! thumb up!

[@LivingWithAClassic]

Thanks!

[@kathykirby5837]

Great video! I couldn't do the mathematics to save my life 😂. But very impressive 😀

[@LivingWithAClassic]

The maths weren’t too bad but explaining them was the difficult part

[@mikedx2706]

Congrats on a successful installation of the 123 Dizzy. In my experience the best money I ever spent to improve the performance of my cars has been to install a new high performance distributor. Especially here in the USA where the factory distributors were set up with a lot of ignition retard and lazy advance curves for exhaust emissions control purposes. Do you think the 123 Dizzy has improved the engines "driveability" and throttle response?

[@LivingWithAClassic]

So far it feel more alive and more willing to rev. I still need to drive it more but so far it feels great

[@martinclapton2724]

Result!

[@natesteiner5460]

So on a 6 cylinder engine with the standard 1-5-3-6-2-4 firing order, #1 and #6 pistons move together so you can time the engine off either cylinder. That is 10 degrees before TDC on #1 is also 10 degrees BTDC on #6. Jag for whatever reason numbered from the flywheel forward instead of front-to-back. And yes, you can also time a typical 4 cylinder engine off #4 for thew same reason.

[@johnmoruzzi7236]

Nice upgrade but do you need more modern HT leads with these electronic distributors ? Are your new ones suitable ?

[@Lotusvvc]

Another great video Adam - thanks. Do you know if this can this be done on a V12 HE engine in an XJ-S?

[@LivingWithAClassic]

They don’t have a V12 version. The Lucas system used on the HE V12 is very reliable and works very well though

[@barryphillips7327]

Electronic ignition on ANY older English car a well worth while UPGRADE!!!!

[@LivingWithAClassic]

Sure is!

[@victorstillion699]

@@LivingWithAClassic I have a 420G 1967 can I remove the head nuts that hold the plug wires in the casing with out disturbing the heads

[@MothsandRods]

Hi this is really helpful especially the advance curve maths. One question. For my 1969 E Type 4.2, would the curve be the same as yours? Can I just copy your numbers into the 123 app? Thanks again Simon

[@LivingWithAClassic]

Yes that would be the same curve and yes you can just copy them. I took the curve from an old instruction on how to test those distributor. It is a Lucas 22D which was used in 4.2 E-types and series 1 XJ6.

[@ralpha4957]

yeah maybe moving the coil far from the block on s2 jag is better but i think the original center wire is too short

[@LivingWithAClassic]

I have measure and it will work with the original HR lead. Will just need to alter the other wiring

[@alexandrecouture2462]

Great video! Of course it is a great upgrade, even if all old heads will reply and say that points are better :)

[@LivingWithAClassic]

Points are of course not better but they’re cheaper. I think this will be a good upgrade

[@steinr02jaguars49]

Adam, I’m curious to know your record keeping for your cars. Shoe box full of receipts or glovebox full of notes… On my cars I keep an updatable 2 page email printout of the maintenance intervals and work done in my glovebox. All the cars I’ve purchased came with zero history…frustrating to know what has been done and when. It’s very useful when I sell a car….here is all the work done and how much it cost.

[@bobcooke6346]

Sorry, did I miss you moving the coil, I thought you planned to mount the coil on the side away from heat ?

[@gaz1tinsley]

Been watching for a while now and i love the progress that your making, that bluetooth link is amazing do you know if i can get a bluetooth link to my jag xj6 3.2 x300 1995 ??? im sure it must already have electronic ignition ?

[@LivingWithAClassic]

I'm glad you like it! Your car has coil on plug which is far superior that this. Not much needs to be done with those ignition systems since they are still very good.

[@gaz1tinsley]

@@LivingWithAClassic Thanks for that, Keep up with the good videos !

[@BrianMadsen-yj8df]

Hi Adam! Just out of curiosity, how many inches of mercury does the app say that you have at idle? I fitted my 123 and it says that I have -7. Just wondering if yours is similar. Thanks!

[@johnball4826]

Just watched this video. There is a mistake in your programming on the vacuum section. The very first point number 1 @ 0 pk should also have 16 degrees. Otherwise your vacuum chart does not make sense as the advance should not have that drop off. Also, have you noticed that the screen now shows the possibility of putting in a note about Static advance. This came about from a software upgrade.

[@hueyhoolihan582]

from where is that app getting the chargin info?

[@LivingWithAClassic]

The distributor is connected to switched 12V from the car

[@loris3615]

Hi gentlemen , someone know what is the right curve to select on the basic ( no Bluetooth) 123 ignition for an xj6 4.2 series 1 ? Thanks for your help

[@LivingWithAClassic]

It’s curve 6

[@loris3615]

Thank you very much from south of France. Enjoying your videos since long time . It’s help me a lot for the restoration of my jags.

[@LivingWithAClassic]

I’m glad you like them!

[@nikifly2]

why do you replace the coil ?! Should also rum with the original 1,6 ohm coil

[@LivingWithAClassic]

Because I had a misfire and didn’t want to use my old coil
