ignition advance

Postby stroker007 » Fri Nov 04, 2016 8:19 pm

hello

this my way in my race car :

zero tdc = 8 ( in my pully zero = 8deg )
lock mode : 20 ( because 8deg mean 0deg ... so 20deg mean 12deg in my distributor )
in rpm3000 timing : 46deg ( i need here 38deg .. but whan i write timing i add 8deg in every cell )
haltech elite 750

My way is correct?

( i add 8deg in every cell )

Why wouldn't you just adjust the trigger offset so your timing matches correctly, instead of adding 8 to every cell and having to do math in your head when making changes?

You don't have to. Simply lock the timing, then adjust this until the timing light and the locked timing agree.

when i set lock mode to 15deg ... directly i got 15deg in timing light .

something i tested :
i set lock mode to 10deg ... sound engine like 0 - 1deg .... so i think my way is correct ... 8deg in lock mode mean 0deg in the engine ( in the engine not timing light )

and 20deg in lock mode mean ... 12deg in the engine

you are tragic...and you will destroy the engine...when you lock the timing in 5 or 10 or in 20 then timing light must show the same advance not less...

so when you set to 10 you must see 10 on timing light NOT less or more

TIMING LIGHT DEGREE is the engine degree...thats why we synchronise it and MUST match with timing table on the ecu

sir your words correct ... but i think no one understand what i mean in my problem :(

.......
in the pulley ... there many number timing ( 0 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 - etc... )
you know TDC ( top dead center ) is 0 in the pulley ...
but in my pulley there a wrong marker ( by bulider engine ) ... in my pulley 8deg TDC ..... so 8deg is a top dead center .... ( 8deg = 0deg in other engine ) .... so i put 20deg in lock mode .. and i get same in the timing light 20deg ... but if you calculate you will know it's 12deg not 20deg

we dont understand because YOU DONT EXPLAIN...just now you explain about incorrect pulley...

remark your pulley and synchronise it with timing light...
