123TUNE for Stag - Custom Settings

[V8 Trip2Tipp]

Hi all,

Took receipt of my custom built 123TUNE distributor today (built by Henry @ 123ignition-conversions.com) have it fitted & initial test run went fine but I felt that car was lacking a bit of pick-up though running VERY smooth!

I've been using the standard pre-loaded "Stag Curve" and haven't tinkered with any of the adjustable settings (yet). Has anyone any experience of the 123TUNE product or any advice what to try adjusting first?

I've used the 123 (standard catalogue parts - not the 123TUNE version) in my 2CV & MGB & am absolutely convinced of the products superiority. Pricey solution but they are the business!

I'll try a few tweaks tomorrow but I'd be interested if anyone has a suggested setting or indeed wants to share their settings file?

One other question.... I set-up static with help of the 123 Ignition LED indicator & tried my cheapo timing gun but couldn't pick-up the timing marks... I was using No.1 cylinder to pick-up which is normal for most cars. Is it different for the Stag?

Many Thanks guys

Cormac

You should time off No2, the first cyl on N/S bank. Good luck!

As above, use the No.2 Cylinder (The first (front) cylinder on the nearside bank) in order to time the system.

Another thing is if the timing mark is not present, rotate the crank manually and see if it is rusted over (I have seen this on a couple of old Triumphs previously). I will be interested to see how you get along with the 123 system, after seeing a wide array of success in the Mini and MG circles.

Hi Cormac
i have been in touch with 123 Ignitions about a year ago and I like the idea of a mappable ignition for the stag. Until recently this was the only one I have seen but now the new (less expensive) Aldon system is coming along I will be watching that. Only time will tell which is the one to go for.

You say that it is loaded with the standard Stag curves, but there are three different distributors (41336, 41525, plus the very early 41276) each having a different curve. So you may like to try the others too.

Do you know what compression ratio your engine is running on? That would give a guide as to what to do with the curves. Alternatively a good rolling road technician should be able to set you up how you like it, eg for max torque.

I am am glad but not that surprised that you are getting a good response so far. As for the way ahead, you could be playing with the settings for a long time, but then perhaps that is half the fun!

Enjoy!

Hi Cormac

I have just had a look at the 123 website but in the list of products there is no mention of a version for the Stag.

Is it new to the market or is there another company modifying the 123 dizy for the Stag, if so, what are the details and how much does it cost?

Hi guys,

Many Thanks, the timing from No.2 is spot-on!
123TUNE for the Stag not available as a factory part.
Mine is a custom conversion by Henry Hebels (have a look at 123ignition-conversions.com), Tried a few things today, but seem to be having a bit of difficulty with the Vac advance curve but have a query in with Henry so hold tight until I get it sorted. The live USB settings are amazing - I can advance / retard at real-time at the press of a button!, it's real space age dream stuff!

Since the new distributor is fully adjustable from the laptop, I just need to play about with settings, can't say I'm there just yet but it seems work will get in the way of playing with it for next few days - has the potential to be the business & is very user friendly.

Unit was €450 (with €100 of surcharge for old unit), postage to Ireland was €23.95, saucy enough but I'm a big fan of the 'new' dizzy concept - totally re-manufactured, new bearings etc. no free play at all! I've used a number of different ignition systems but this one is the business. Just need to keep playing with it for a bit, will do my best in the shed but will need a good rolling road place to sort me out for optimal performance - Know of any in Ireland?

I'll contact the Triumph Classic Owners Club guys in Dublin for a bit of help on that one.

Anyway, I'll let you all know ow I get on.

Cormac,

Any news on the distributor? I have a ex-USA stag with a "federal" distributor and are looking for better performance. So instead of buying a UK spec distributor I would like to go the way you have.

[ChasR]

The chap who converts the Stag distributors to 123 items is based in the Netherlands (email is :h.hebels@planet.nl). I have seen his workmanship on a Dolomite distributor (which like a Stag, has a distributor unique to the engine) and the quality of it was superb:




Henry may be able to help you out with your distributor Ian if you can't find a solution closer to home . How is your distributor different to the twin point UK items? I know on other BL cars they used all sorts of strange contraptions for US cars (including the electronic Lucas Opus, allegedly nicknamed 'Opeless').

Either way, Henry seems willing to convert most unusual distributors to 123 spec (going by his ebay website).

[Stagdad]

Do they tell you the amount of advance you are getting or is it just several curves? Would be good to know for setting up a mappable ignition table on something I'm playing with.
cheers Steve

Steve, Henry fits the 123 Tune system into a stag distributor. The Tune version is mappable, and you can store 2 maps that you can flip between using a switch, eg if you are changing from regular to super fuel. Tghe older 123 systems were only switchable not mappable.

V Mad,

I do not know what type of distributor I have. I can see that the vacuum is connected to the opposite side of the diapraghm than the UK type, so I know it is special. I can not find anything about a special Distributor in the Repair Operations Manual that came with the car. The manual states that the distributor has Lucas part no 41276, but I found another post from you suggesting that this was the distributor from early Mk1's? Where is the number located? Can it be read while in the car?

[iani]

IIRC the number is stamped on the casing but facing the rear of the engine bay, by using some plasticine you can make an imprint of it that you should be able to read.

I must remember not to let you have my car keys Ian or is that only if films they do that

You may want to contact Neil (flying farmer) I think he has a lambda probe set up in the exhaust system that will then show you what the state of combustion is so it will take some of the hit and miss out of the tests.
