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. |
