Default Distributor cap rotation for more power

Isnt there a cheap trick to gain more power by turning the distributor cap up towards the firewall?
I know it worked on civics but couldnt remember which way it was suppose to be turned.
Thanks

Yes, you have to jump the service connector inside the car first. The little blue plug with 2 wires (5th gen) under the right side of glovebox. Be careful when you advance timing and use high octane fuel. If you hear any pinging or detonation you've advanced too far,

why do you need to jump the blue plug first?

so when you make the changes the ECU will save the settings in its memory.(i think i heard someone say that before).

the reason you jump it is: the computer will not advance/retard (as it does in normal operation) so you can actually set it... (depending on the operational mode of the ecu the car may already be well advanced). basically you're setting the base timing @ BTDC , and then the ECU figures out the curve from there.

hondas kinda funky, most cars have a timing spout you just pull. make sure you have the car off when you jump, and then turn car off and unjump.

which part??

what i meant was hondas differ in that - most cars i've worked on (OBD1 and below) have a timing spout you just remove or a wire you jump near the distributor. it kills the computers advance/retard capabilities while you set base timing. however you should always jump/unjump (including your honda) while the engine is off.

i guess i shoulda added that adjusting your timing is a obd1/0 thing unless you have a OBDII electronic pad gizmo... I could be wrong on that, but every dyno run i've seen of an OBDII car they had some laptop like controlpad to adjust timing, knock retard etc.

well i was assuming you know the car needs to be running to time .. sorry i hope this is clearer:

car off; jump connector. start and time car to your desire. car off; unjump connector.

has anyone done this to a stock engine? can any harm be done? what advantage do you feel after you've done this?
