Electronic Ignition Vacuum Advance at Tamika Hamilton blog

Electronic Ignition Vacuum Advance. The debate centers around whether straight manifold vacuum is better (or worse) to connect to the vacuum advance canister than. The flame speed slows down, so the spark advance was bumped up with a vacuum diaphragm to start the ignition earlier. In later engines, a vacuum signal was taken from the carburetor that had a different vacuum characteristic, more ideal for emissions. When at cruise manifold vacuum is high and the vacuum can on the distributor provides additional ignition advance for improved gas mileage. In fact, i’ve heard guys say they’ve locked out their advance and just run a fixed timing amount. The added ignition timing from the vacuum advance allows the lean cruise mixture to achieve as complete a burn as possible during. When car is accelerating manifold vacuum is low and the distrbutor operates on mechanical advance; At part throttle initial, vacuum, and mechanical advance are all added together. When load is applied and manifold vacuum is lower, less timing is added because the cylinders are more densely packed with air and fuel, and require less ignition advance to create maximum power. This video from the experts at msd explains the distinction between mechanical & vacuum advance & its role in your ignition system. Is this a better way to go with a street engine? That additional advance can easily be a additional 20 degrees, for a total advance in the 50s. I’ve always thought that vacuum advance was something just for stock engines and something you didn’t use with a performance engine.
