how do i advance timing???

i was also wondering this

Can any N/A guys who have advanced their ignition timing please tell me what you set the timing to for the max hp gains. thanks alot

to set timing, you need to put jumper in the diagnose connector. I for get which pin exactly, but it's the same one you use to read your code for obd1.

Just loosen your distributer and turn it clock wise (advance) and counter clock ( retard) and at the same time look at your timing mark. I set my to 18 BTDC and it seem to be pretty good, but not dyno yet. Stock is at 10 BTDC.

Im not exact on the rotation of distributer for advance/retard.
Been awhile since I last check timing.

cool

thanks alot moua4c
i am going to do that tomorrow and will set it at 18 and see what happens. i'll post when i get it done.

bump i need to do this today my cars being dynoed either later today or tomm. which way do i turn it and where is the timing mark?

how did u go??

so you're an "all motor mkiv guru" and you dont know how to change the timing?? :lol:

Dyno sheets please

uuhh i think if you look on the under side of the hood youll find where to jump the diagnosis box...

Get your timing light. Hook it up as directed by the instructions for your timing light - one lead will hook up to number 1 spark lead.

Then check idle speed.

Undo the nut that secures the distributor. Start engine and check the timing (should be 10 dgrees advance at the correct idle speed). Then rotate the distributor to adjust the timing. When you have set the timing to what you want it to be, tighten the nut. This will not affect the cam timing at all.

Of course, if you change the exhaust cam timing, you will need to correct the distributor timing.

how exactly does a timing light work? im just curious as ive never seen one in person. does it display something? b/c i knwo your supposed to point it at a certain spot.

A timing light is basically a xenon flash tube powered by the inductive current that passes thru a spark lead. It has 3 leads - 2 leads are connected to the positive and negative terminals of the battery and the third lead is connected to the spark lead for cylinder 1. When a current passes thru the spark lead, this induces a current in the circuitry which triggers a flash from the xenon flash tube.

The timing light is pointed at the crank pulley. There is a timing mark there which tells you where in the cycle the spark is occuring when it is referenced against the timing marks on the timing cover. For example, when the timing mark is flashes at 10 degrees, this means spark is occuring 10 degrees before top dead centre.

for you peoples talking [email protected] go fuck yourselfs by the way thank you for the ones who replied to the post. i just wanted to make sure that was the right pins to jump plus what the right stock setting are. im dynoing wednesday so if you are going to talk [email protected] wait to see the dyno results.

pfft. NA 2jz`s dyno so low, does it matter?

Please have a scan ready.

I see irony that you find it necessary to put the @ sign in the middle of "shit" so as not to be cussing yet you freely tell everyone to "fuck themselves." Anyway yeah I would like a legit dyno to be shown too as well as all your "super secret" mods. Also when you advance your timing as gianttomato said dont forget to jumper the diagnostic port as moua4c mentioned otherwise your timing is just going to jump all over the place.

Good Luck

well what kind of numbers are you expecting? we have been waiting on this dyno for a while..

How do i advance the timing on a 93.5 n/a mkiv supra? how would i advance the timing on the stock setup with no cam gears and what degree would you recommend? 10 degree advance i have a timing light and evrything i need to do it> Thanks

the way I was told is keep going up untill you hear pinging(preingnition) then back off 4-5deg. you have to stay on the same fuel tho, and it's best set on a very very hot day.

k Thanks i hoping for around 220-228rwhp which would be damn good for a automatic. also i am taping the runs aswell. im am going to test and tune the ignition timing since it nice out .

- and i apologize for cussing . there is nood need to post and talk [email protected] if you have a problem with anything i post let me know . i am trying to help out the na community as well . i should have never talked about secrets mods or anything. i just did not want to post things i have done and not have numbers and or track times to back it up. lets call it truce and ill be upfront with the mods for now on-. p.s i never finshed that custom intakemanifold ;(
