hi guys how do u increase the ignition timing on a 99 civic ex?

thanks

 

Turn the distributor counterclockwise to advance the timing.

 

my friend told me something about loosen 3 bolts from the dist and resetting the ecu but that was for his integra though

 

They should both work the same way. Be sure to tighten the distributor bolts back up when your done and don't advance the timing past about 20 degrees BTDC. Run premium fuel too. Your engine is going to get hotter and you may have trouble passing smog so you might want to turn the timing back for smog.

 

You have to jump the service connector above the ECU(green rubber boot). The check engine light will light up. Then you can loosen the 3 distributor bolts, then set the timing. Thats all you need to do, don't forget to remove the jumper.
