retarding timing
 

which way does my distibutor go to retard it forward or backward? and how much do i need to move it for 7PSI?

i have a b16a2 , the distibutor is left of the engine

blarble

Re:retarding timing
 

turn towards the front of the car to retard, and towards the firewall to advance.


also wen moving the distributor: if the idle goes up, you are advancing it. If the idle goes down then it is retarding it.

Re:retarding timing
 

what should i put it too for 7PSI

Re:retarding timing
 

can i just move it all the way towards the front?

Re:retarding timing
 

uhh i have no idea how many degrees that will put you at...

get a timing light.

Re:retarding timing
 

Are you running an AFC? Otherwise I can't see why you would want to retard it that much. ??? You will also need to jump the two wires under the dash or the ecu will not retard the timing. Jump the wires, turn the car on, loosen the distributor, turn it clockwise to retard it, tighten the distributor, turn the car off, un-jump the wires. Turn car on and go.

Re:retarding timing
 

retard it 1 degree 2 max...

Re:retarding timing
 

can i just use the gun, what is this jumping wires your talking about?

Re:retarding timing
 

Have you ever checked a cel(check engine light) on your car before? You jump those wires together. They are near the ecu on the passenger side. They should have a blue/green(sorry I'm color blind) wrap on them. There should be two connectors. One has two wires and the other has three. You need to use the one that has two.

I don't understand why everyoen says you need to trip the cel code reader jumper to set timing... If you move the dizzy with the thing not jumped while looking @ the crank with a timing light you can watch the timing move... Moving the dizzy is a PHYSICAL CHANGE (since your actually changing the timing by spinning the electrical connections) and is 100% independent of the ECU as far as I can tell when moving it. Test it for yourself. You may not get an accurate reading of your base timing with the thing not jumped... I assume that is possible... but no matter when you mess with the dizzy, jumped or not, your timing does indeed change...

Re:retarding timing
 

Your ecu also manipuilates the timing. Like how the AFC hack also causes the timing to advance. If you move the distributor without jumping it, the ecu will be trying to correct this. It might not be at idle as much as it is at cruising, but it is correcting it. Test it for yourself.......

Re:retarding timing
 

IMHO, if you are doing your boost/timing retard at the distributor, Id retard a minimum of 4degrees.
Like said B4, jump your service connector, pull the IACV plug from the back of the intake-manifold (get it to idle low enough so the ECU isnt adding timing) and time it to 12-13 degrees BTDC.

On an interseting side note, I played with the service connector to see if there was a difference in timing. In my case with the car idling at 800, there was none. Both the gun, and datalog showed the same. (I did have my lowspeed timing map expanded so there would be no timing change until like 2000rpm, so that may have been a factor). If you are on the stock ECU, it will begin to 'add' timing after 725rpm, thats why you want to pull the IACV plug to get it down.
Maybe Joseph D. will jump in on this one.

Re:retarding timing
 

what 2 wires are you talking about. What do you have to do with them. Do you just leave your eacv unpluged all the time?

Re:retarding timing
 

so is using a BTM bad or should i just retard the timeing manually?

Re:retarding timing
 

Plug the IACV back in when your done timing it. If it runs funny just reset the ECU.

Your OBD2?, sorry, know very little about them; I was just blabbing about the service connector thinking you were OBD0-1.

IF the idel is under 725 w/ no load dont worry bout' the connector. Might wanna invest in a manaul huh :P

Re:retarding timing
 

Detonation is ------- retarded.

Re:retarding timing
 

what 2 wires do you have to jump and whatdo you mean by jumping.

Re:retarding timing
 

the 2 wire connector under the dash at the corner on the passenger side.

btw you should get a manual if youre gonna be doing this or anything else in the future.
