I'm need of some clarification, I have a 1974 1.8 L with a current Bosch distributor (0 231 181 009). I have two vac ports on my throttle body , one that goes to the distributor (vac retard) and one that comes from the distributor (vac advance) back to the throttle body.
My wife gifted me a 123ignition with blue tooth to replace what I have. I told them it is for a 1.8 Liter engine (L-Jetronic Bosch Fuel Injection). They provided my a new 123/TUNE that was designed for my current set up. The new Distributor has a vac hose port on it. My question is that I had a vac box on my old distributor that had one hose coming from the throttle body and one coming back to it from the distributor. Now I have to figure out which hose I should connect to the new distributor and which hose shall either be plugged up or just left open and not connected to anything. I guess I'm missing something maybe??? I 've read here that there are some 914's that have one port or two ports on the throttle body (possibly due to CA emissions and an EGR valve). I was really looking forward to adding the new electronic ignition with Bluetooth tuning, but I'm not sure to set it up correctly. Any ideas? Thanks. |

You can use either the retard or the advance port of the throttle body hooked up to the distributor (or neither). Just plug up the one not in use and set the 123 curve accordingly. Just don’t plug the port on the distributor if you leave it disconnected.
Make sure you time the engine correctly by setting the advance on your timing light to match the advance of the 123 (22 degrees I think). |
