Also my first read of the instructions indicates I need a PC laptop to set it up. How this works with the wires that come with the distributor is beyond me (and I don't have a PC laptop), but Max at Alfaholics programmed in their own special program, in addition to the ones that come with it.
Biba - the programmable one will have a USB port that you plug a standard USB cable into. You don't need a laptop per se, but you need a computer that is close to your car or maybe a super long USB cable.

Stefano, thanks. Where would I find the USB port? I've not seen one but I understand there are mini USB connectors, but I can't find this one, whatever the size might be.

Will the car start without the computer?

There should be a hole with a port. Here is a picture of the hole with the black cable coming out. I would guess you could start the car without the computer but I'm not completely familiar with it.

123 go

I was running #4 and switched to "D" after reading up on this writeup. The car runs and idles much better. I also "red up" on the Bosch red vs Bosch blue coil. What I read is that the internal resistor in a blue is to help preserve the life of the points. Without points, you can use a hotter coil without an internal resistor such as a Bosch red. Runs better so far. Switched out my Bosch +4's to NGK BPR6ES plugs at $1.67 ea! Nice price.


I was very happy to see my compression was 142 even in all cylinders.

More checking to do on the fuel system. Not sure if I'm keeping the mechanical fuel pump. The carbs are preigniting, and the spitting doesn't entirely go away with warming up go or by pulling out the choke . I need to replace the gasket in my FISPA filter with a $70 kit from Geoffrey Ohland at PARTSOURCE. Glad these rebuild parts are still available.

Dr G,

What's the part number of the Bosch "red" coil you are using?

Preignition solved by adding an electric fuel pump. It seems the mechanical pump just not putting out sufficient fuel pressure. If the carb spitting went away by piggbacking in a fuel pump, and all my filters are new, makes sense to me!

Next up MSD install. There is a very nice place right behind the glovebox area inside the car.

( I know the engine bay is dirty, but getting the engine running better before housecleaning.)

Wes, are you sure the Bosch red coil can be used reliably in the 123 distributor? I don't use the 123 but I think the manufacturer recommends against using low resistance coils such as the Bosch red coil. The blue coil has an internal ballast resister and is higher resistance.

Two companies that sell similar ignition sensors, Hot Spark and Pertronix, specifically warn against using low resistance "hot" coils with their ignition modules. I don't know what the 123 uses, but I kinda suspect that its module may come from the same Chinese factory as the Hot Spark and Pertronix. Pertronix now has II and III version modules that are more robust and can be used with low resistance coils, but the I version cannot. It might be prudent to check with 123 and see if their latest versions can use low resistance coils.

The data that I have seen on the Bosch Red coil gives 1.3 ohms for the primary resistance. 123ignition state that it should be used with coils of 1 ohm or greater. So it looks to me that the red coil is a good choice if you don't plan to use an MSD box or similar device to drive a blaster type coil.

I'm not well educated on this but

2002 IGNITION SYSTEMS AND CONVERSIONS

led me to believe I could use a red coil and an MSD.
Couldn't get the MSD 6plus running today, but there is a not-so-well-explained green wire that I may need to cut on the MSD. I'll call on Monday to try to figure it out.

It was a sad day as my mechanical fuel pump doesn't seem up to the task. Then no start with the MSD, but tomorrow is another day.
I do agree with Racetep that the Carter p4070 is a great pump. Just opening the box and comparing it to a Mr. Gasket pump is a joke. Mr. Gasket has no bracket, no isolation hardware, no clamps etc. I'll let you know how that goes tomorrow with "Mr. Carter" when I get a new main fuel line from Williams Oil Filter.

You can. You can also use coils with lower impedance.

I have my 123 hooked up to an MSD6AL. PM me if you want my telephone number. I will be happy to help you.

IMHO, an MDS6A in combination with a good breakerless distributor is a splendid choice for an ignition. The 123 w/ programmable capability brings everything to a new level of tuning since you have the option of starting with one of the built in well-established curves and then tweaking it to fit the engine in your car.

Ed, I thought the Bosch red coil had a lower resistance than 1.3. I stand corrected.

I too had assumed that the red coil was below 1 ohm until I looked it up.
