|
|
I am seriously considering updating my distributor on my 6V Notch to a 123. But I am also thinking down the road, I would change potentially from 6 to 12volt. So I have a few questions for those who have a 123 distributor.
1. Is there any special modification or upgrade required on the 123 if I change to 12 volt other than the 12V coil?
2. Is the base 123 distributor not programable and requires the Bluetooth option for programming?
3. Is it really it an install and forget about it, or do you still need to check timing when you do the usual 3000 mile tune up?
4. Is the 123 Epoxy Coil critical for compatibility, or will the stock coil work?
My thought is to install and have the original distributor out on display by the engine compartment if I do a show? It would look all nice and pretty on a wood block stand.
Thanks in advance _________________ Ossipon

The best person to ask this question would be Tram (send him an e-mail). I only say that as he's got the most experience on here with working with them, and has been the big push to using it (for FI applications). You do have some valid questions though. In my case I've already converted the car to 12 volt, so a 6 to 12 swap down the road isn't in the cards. I was looking at using it if getting quality Bosch tune up parts are going to be a problem though, and I do like that the trigger points for the FI is already built in (can use it in the wife's car). _________________ Bob 65 Notch S with Sunroof

1. Is there any special modification or upgrade required on the 123 if I change to 12 volt other than the 12V coil? No. Just make sure you choose a coil that has the resistance that they recommend.
2. Is the base 123 distributor not programable and requires the Bluetooth option for programming? The base distributor is not programmable, but will have several different curves you can manually select to see which one suits your driving style best. In my opinion only, the Bluetooth model is sort of a pain unless you are doing a lot of racing and autocross, or need a custom curve for your application. I have run into a few instances where the Bluetooth model suddenly will not connect for some reason. Since I am a low tech boomer, this may be operator error but the "set it and forget it" models offer plenty of additional punch and driving fun simply because the digital technology removes absolutely ALL of the inherent "slop" present in mechanical distributors even when they are perfectly set up
3. Is it really it an install and forget about it, or do you still need to check timing when you do the usual 3000 mile tune up? Checking doesn't hurt anything because there's always the possibility of something stupid like a loose clamp, but beyond that, no.
4. Is the 123 Epoxy Coil critical for compatibility, or will the stock coil work? Stock coil will work as long as it has correct resistance. They do recommend a "fresh" coil, though, because a weak used coil can cause issues, as can low battery charge/ faulty charging system.
My thought is to install and have the original distributor out on display by the engine compartment if I do a show? It would look all nice and pretty on a wood block stand.
Thanks in advance |
Pun intended?
Hope the above answers your questions. I'd suggest buying directly from 123ignitionshop.com in NL as the prices are good, delivery is fast, and the support from this crew is fantastic. _________________ Немає виправдання для війни! Я з Україною.

It takes a lot of work to get all of the slop out of the FI distributors. The 123 is a better choice for FI because of this. The only reason you want the FI stock distributor is for a show car. I can remove all of the slop out of a stock distributor but it is a tedious process. If you don't get it right the FI system will not behave correctly. _________________ www.vwnos.com [email protected]

Awesome information, but no one answered his question, he owns a ‘64 dual carb 1500 cc 6 v engine, and like many of us, tinkering with the idea of making the switch to something more modern. _________________ I'd be UNSTOPPABLE if not for Law Enforcement and PHYSICS.

I answered the question. Yes, to switch to 12v, all he needs to change is the coil.
The 123 will work with any system from 4-15 volts, clockwise or counterclockwise rotation per their website. _________________ Немає виправдання для війни! Я з Україною.

I thought the Bluetooth version was "forget it" as long as you have set the curve.
I have a Bluetooth 1-2-3 waiting to be installed in my 1964 1500S. I selected a Bluetooth version to be able to set exactly the 1964 1500S centrifugal and vacuum curve - not something similar from a library of curves. |

For some weird unknown reason , maybe a glitch in the matrix, I did not see the redacted quote where you answered. Until now! _________________ I'd be UNSTOPPABLE if not for Law Enforcement and PHYSICS.

the only issue I have heard of was from Shin Wantanabe - the 123 does not like original style voltage regulators on his car. electric noise and voltage spikes cause it to go to safety mode, making the car pop and sputter. He had to switch to the newer solid state style. In a type 3 that's no biggie because it's under the rear seat. On an early bug where the regulator is on top of the generator - the newer style is kinda ugly. Wolfsburg West and BBT have a SS Regulator that looks more vintage, and Shin went further if I'm not mistaken, and modified an original cover to fit the BBT solid state regulator. Anyways - throwing it out there if you have any issues because that would likely be the only issue you'd have. He is also running 6V - suped up 36hp motor |

Which would you suggest for a rebuilt 1600 with stock dual solex carbs? Im seeing three types, one vac advance. is the Vac advance suggested?

The instances I am referring to are where the end user has a couple different curves for different driving styles and regularly switches between them. If you set it ONCE and never again it should be fine I think.
The 3 I have seen fail to connect were all 911 applications. _________________ Немає виправдання для війни! Я з Україною.

I personally prefer it as it is designed to function with your stock Solexes as original. _________________ Немає виправдання для війни! Я з Україною.

You don't need a 123 for that. You can use the stock distributors. _________________ www.vwnos.com [email protected]
