Heading to the garage now to start the install and my main, unresolved-in-my-brain question is if i need to hook up the vacuum line that is on my current stock distributor, on the 123. |

This reply comes straight from the mfg.
Hope this helps All 123\Tune and 123\Tune+ have the vacuum advance and boost retard option. Everything which you program in the MAP curve below 100kPa (atmospheric pressure) needs to have a positive advance value, which leads to vacuum advance. All values above 100kPa are overpressure (boost) and so you can only enter negative advance values which is retard. For example: 0kPa: 10 degrees 80kPa: 10 degrees 85kPa: 0 degrees 100kPa: 0 degrees 110kPa: 0 degrees 130kPa: -5 degrees 200kPa: -5 degrees This example curve gives advance below 100kPa and boost retard above 100kPa. |
