ok so i am replacing the timing belt water pump etc... and i want to sett the timing at 18.. because that is suppose to give you the best performance... etc for a b18c1... correct me if i am wrong.. but i hear that the ecu will automatically change the timing of the car... well how the hell do i set it on 18 with out the ecu changing it in a few days.. how do i get around this.. someone please explain?

 

you have to short the pin under the dash... search for timing adjustment, should be some pics. This can be done w/ a paperclip, its also in the helms manual.

 

yes, if you engine sense a knock caused by advancing your timing it will electrically retard it. but you can trick the ecu to take the advanced timing by jumping the service plug. and then do your timing. then the ecu will think what ever your new time is stock timing

 

service plug.. the thing u jump in order to get the ecu code???? the green thing?? also if i do this will it reset itself when the battary is unpluged? back to 16? and is 18 the best?

Yep

This i'm not sure of, but i dont think i remember seeing a reference to that in the helms (dont have mine w/ me).

 

does anyone know?

 

Since you short the ECU to set the timing and its the physical location of the distributor that will be what you use to set the timing i'd say no, unplugging hte battery wont reset timing.

 

the thing is if you dont short that plug and do timing, then the computer will keep retarding the timing as you advance. Now if you short it, when you advance the time, the ecu will no compensate. thus if you want 18 you get 18.

 

isnt it good that the ecu resets the timing when it knocks? knocks are bad.

18 degrees wont cause knock. unless you use really shitty gas.

 

yup, in fact honda specificies that the timming should be between 14 - 18 BTDC. So you are still in spec at 18.

 

is 18 the best?

 

FYI... what you're talking about is base timing. i.e. at idle and fully warmed up. The computer will adjust actual timing depending on engine load, throttle position, and a bunch of other things.

 

so any how is 18 the best setting?? and stumpyf4 do you mean that i will never get it set on 18 permentatly.. with obd2?

 

meaning hte computer is alot smarter than we are and makes decisions regarding fuel and timing much better than we do.

Set it to 18 and forget it.
