 Sorry I missed your question about the 123 tune

 Just read the instructions that came with it and read the long thread a couple of times

The most difficult part is setting up the curves. The Light they talk about that denotes TDC I never could find. I think it is on the exterior of the distributor and shines down on the engine. You don't even need it.  Just get it close and crank the motor until it fires   It helps to have a friend twisting the distributor to get it to start but I've done by myself by just making small changes in the  distributor  until it will run by itself  Then you can tune it by hand to find a good idle. I never really checked the actual static timing. I just found the best idle and went from there  I know my motor is using a lot of advance at 3500 RPM   Also The wiring instructions are a little vague about the switch for the second curve but you can figure this out.

Remember this, A Lean mixture like at idle and cruse take longer to burn  hence you need to light the match sooner   This is where the vacuum advance  comes in under low load situations.  If all you did was drag race at full wide open throttle all the time you wouldn't need vacuum advance.  The vacuum curve has the motor already set to go when you transition from cruise  to wide open.

Give it a go   read a search thread about setting timing to get comfortable with how to find top dead center and set the distributor. 

 Once you have done it you will be proud of yourself

Best regards

I'm thinking $ 60 shipped on the pump

Regarding Distributors  Yes I had a new Tii electronic but ditched it for a 123 Tune ( usb cable type)  and the difference was nothing short of amazing  It woke the car up

I just used a Blue coil  with it and find it is adequate.   You don't need more spark like MSD

There is a Bluetooth version but I hear it has some bugs to be worked out.

The usb version connects to a laptop and works  fine

There is an extensive thread on the subject of the 123 tune  that's about a year old

do a search and you will find plenty of reading  including my comments

I have the Tii mechanical cure plus some vacuum curve  Don't' recall the detail  but  my is on a built motor so your curve requirements may be different

These things are not cheap  $400-$500  but they are worth the expense  Find a seller in Europe, the prices are cheaper than the US seller

Currently putting together a 74 with a 150 hp build and I purchased the 123 tune without giving it a second thought

Back to the pump
