Need help understanding retarding and advancing ignition timing!!!!

[10thcb7]

also, dont forget to jump the blue ECU check connector before adjusting timing... and reset ecu when done.

oh prnonvtec4u you must be correct i havent looked in a while more than likely your right

[deevergote]

...

not to contradict but ain't it the red tab?... that's what i've always gone by and it's worked perfectly... there's two white tabs, one right above and another right below the red tab which i considered were the 2degs you're allowed....

It's the middle marker. Mine had no color... just a gouge in the flywheel, with two smaller gouges on either side.

ok. i got lost. what tabs are yall talking about? is it the ones behind that timing plig in the plug between the tranny and block?

I remember somewhere in my high school auto shop textbook says retarded timing will overheat, burn your valves and plugs. Am I correct or my memory is crap?

I assume by "tabs" he means the markers on the flywheel... if not, I'm lost as well! Those marks are all you use when checking ignition timing!



As for retarded timing causing damage, it's definitely possible. If the mixture is igniting as the exhaust valves are opening, it'll be sucking that flaming mixture out past the exhaust valves, rather than the burnt gasses.

Retarding the timing isn't for retards!

i had did a motor swap and i think i may have advanced the timing too much. i do have any bottom end. lol. maybe a little if i put it in D1 but not very much tho. the a6 that i put in didnt have a dizzy. i made sure the motor was at TDC tho before i put the dizzy on. but i may have moved it forward too much.

can i adjust it to where it was on the last motor or just leave it be and have a shop look at it?

Get a timing light, as I told the OP.

I was stupid and put an unmarked flywheel on my motor... I'm lucky I marked my dizzy!

dern. ive been thinking about getting a timing light. so when i get it, what do i plug it up to? how do i know its reading right?

[deevergote]

Read the instructions. I believe you just clip the thing on the #1 plug wire and aim it down the timing hole. Be sure to jump the service port.


Read the posts above... we went through this already with another guy... get the tool, and you'll figure out how to use it. If you can't, we'll help.

The service port is the blue ecu check connector accord91LX was taking about right?
what does it do specifically?

*bringing back from the dead*


so does anyone have any idea exactly how many degrees are those two white tabs that are just a bit adv./ret. from the middle TDC mark? is it the the two degrees that are allowed?...

[d112crzy]

Don't you work at a shop? You guys don't have digital timing guns?

[prNonVtec4u]

i don't work at a shop, i go to school....

and they're broke asses don't

[quaidum]

do u have to take the cap off or the distributor itself to retard/advance
