Ignition Timing Question
Today I was looking at checking / adjusting the ignition timing on my
1995 EG Honda Civic (1.5L D15B7) In the Honda Manual it states that you need to "jump" the service check connector when adjusting the ignition timing. Can someone tell me why this needs to be done and if it makes a difference? Regards, Michael. |

This is the datum from which all other adjustments are made. Jumping that connector prevents the ECU from being able to alter base timing while you set it. -- TeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |
