Anyone have any Pros or Cons for a 123 ignition D-jet tune-4-r-v-p unit for 74 2.0 ?

The only ‘con’ is the price tag, and that’s forgotten soon after you install it- which I guess is really another ‘pro’. (IMG:style_emoticons/default/biggrin.gif)

I'd add that can be a little tricky/confusing to install and get the timing and curve dialed in. Once you get there it's rock solid.

I also have a '74 2.0 and installing the 123 ignition has been a game changer. The engine starts, idles and accelerates much more smoothly. With the USB feature and cell phone app, you can set custom advance curves and see real time data. It was easy to install and the technical support from the company is good.

It is a bit pricey, but how much time do you spend now chasing down spark timing, condenser and trigger point related issues?

Agreed with the others, the price is a little steep but soon forgotten after you have it in and running. I've loved every minute of mine. It's been going for about 8000 miles on the 6-cyl now.

I have an early one for my 2.0 DJet vac port
123/Porsche-4-R-V-IE electronic ignition
It has dip switches you select the configuration for the application
Seem to work VERY well . Drop in and go. No programming needed or special curve files.

I’ve used the Bluetooth and non Bluetooth versions, modified engine use the Bluetooth to tune, stock engine non Bluetooth just pick a curve and install.
I’ve rebuilt several Bosch distributors but the 123 is a different animal, costly yes, worth it, yes.

Yes, my 914 was "bucking" under acceleration. I replaced the throttle position sensor and cleaned the trigger points several times but the problem remained. Installing the 123 ignition took care of it.

That's interesting-I've been fooling with the TPS including a new 914 Rubber board had the trigger points out several times to clean and the bucking problem always comes back.

So how much is the 123 ignition and what is the best model for a 2056 with a mild Webcam?

Thanks-Rick

Low speed bucking was a problem I couldn’t get rid of, 123 solved that issue, I think it is associated with vacuum can problems.
You need a Bluetooth version for tuning.

Pros, just about everything you could think of.

Cons?
Its not free.
Im not a huge fan of the loose spade connectors for the trigger points but they work.

In my 20+ years of messing with d-jet 914s I have found stock distributors to be responsible for a very high percentage of running issues, usually the ones that are difficult to isolate. Having an electronicly controlled replacement for the mechanical advances i one of the best things you can do as far as drivability goes for a 50+ year old car.

I've got one in a 70 1.7 running Djet and a converted 6 with a high compression 2.4 six running webers. I bought one for my BB and will install it soon.

The 1-2-3 is a true game changer. I’ve had great results with my 2056 and fewer issues to contend with.

Agreed. My FI car bucked like a wild bronco until I eliminated everything else as the problem. I had put a 123 in my carbureted car w/Bluetooth and it runs sooooo smooth. One will be going in my FI car. IMO the 123 is underrated. Terrific product and I'll go against the grain and say that it is not overpriced.

I’ll throw in my .02 cause that’s all it’s worth at this point, because it’s just echoing what everyone else has said. I was really on the fence about getting in on the group buy back when they had it, IIRC it was about $500. At the last minute I said F it, I’m gonna go for it. Well it’s been the best $$ I’ve spent on the car as far as improving it’s running (IMG:style_emoticons/default/smile.gif) .

Yes, night and day...

It really wasn’t difficult to install and dial in, I’ve got the Bluetooth unit on a 2056 w Ljet.

The old buy once, cry once adage definitely applies here (IMG:style_emoticons/default/beerchug.gif)
