i need help on doing the timing for my fifth gen.....ive heard that the ecu does it by itself...but mechanics say there is a way to do the timing...so i need to know...and if there is a way can someone give me steps...thanks your help is appreciated.

 

you cant adjust the ignition timing on an a4 motor. the distributor is fixed.

 

well i was just wondering is there any special timing i should know about???the distributor isnt moviable i know that so timing on the ignition isnt possible but do the cams and flywheel have to be timed??

dont those have timing marks?

 

You could adjust base timing by converting to OBD I and replacing your distributor or drilling adjustable hole.
That's if you mean ignition timing, for the cams you would need adjustable cam gears.

 

i thought you can adjust the degrees of the dizzy on the A4?

 

so is there any timing needed for the a4?if so can someone please give instructions or an insight?

 

People have been tring to tell you. The only thing on an A4 you can mess with is the cam/crank timing by adjustable cam gears and how you set the timing belt. Of course there is only 1 right way to have the timing belt set...

If you TB is off, you car will not run right and you will know it.

What are you trying to do?

 

my throttle response has been real bad and mostly when i shift in third from 2-3000rpms the car jerks as it is loosing a little bit of power..

 

OK, so your timing belt is probably off a tooth or so. Just check the marks on the cam gears with the timing marks on the flywheel. Get a manual to give you all the details.

 

So wait...timing on the a4 can only be done through the cam and the flywheel...last time i checked on the flywheel it seemed off...it ran at 12-17 saying it was good through it....but i think there was something wrong...is there??

 

if you are checking the timing properly

- engine at operating temp
- service connector jumped

the timing mark should line up with the timing teeth in the tranny housing. if they don't then you need a new ignition control module for the dizzy.

 

so wheres the control module and wheres the dizzy???thanks.

 

oy, sorry about the slang. the service connector is under you dash. behind that removable piece on the passenger side. little blue thing w/ a 2 pic connection. stick a paper clip in there to jump the connector. dizzy = distributor. your ignition control module is inside the dizzy(distributor).

 

how much do those run for? and can i replace it myself?

 

you are best off getting a new, or working used distributor. not alot of people take the ICM out. good luck, im sure you can get one from someone pretty cheap on here. its too bad, cuz i have a dizzy sitting right here, but ALL the screws inside are fused so i couldnt take it apart to rebuild it.

 

I'm having the same problem with not being able to adjust the timing with the dizzy..what is the purpose of the service connector being jumped for adjusting the timing?

 

It puts the ecu into open loop so it not trying to adjust timing off the stock map. You're supposed to do the same thing when adjusting idle and a few other things.

Ignition timing is done solely by the ecu in OBD2; no adjustments in the dizzy.

 

Hondata and a dyno tune, or any other ECU that lets to play with honda OBDII timing maps.

 

Nice, so is there a step by step on how to do this or do I just plug the jumper wire in then turn the car on and let the ecu do it's magic?

 

i don't think you are understanding. even if you move the distributor the ecu is automatically going to try to re-adjust your timing back to the factory setting. If you want to adjust your timing to something other than factory spec you are going to have to change your ecu. what they were talking about earlier is how to check to make sure the factory setting is correct and you don't have something causing the timing to be off such as a bad ignition control module (ignitor) in your dizzy.

 

I totally understand timing adjustment can't be done with the dizzy. Here's the deal, I just changed out the timing belt and wanted to finish the job by adjusting the timing to factory spec but quickly found out that doing it by adjusting the dizzy wasn't possible, the dizzy has three bolts and not the tradition two so there for you can't loosen the bolts and make the timing adjustment that way. So my question is how to adjust the timing to factory spec? And if the ecu does this on its own is there anything that I have to do to check that the timing is properly adjusted, or properly "timed" so to say? Thanks for your help!!!

 

Sounds like you may have skipped a tooth when installing the belts? Or somethings probable wrong with your balancer shaft assemble. Take it to a Honda dealer and talk to one of the service tech guys and see if he cant give some direction. Some of those guys do know what their talking about....sometimes...lol. I get advice from my service techs all the time. Helps me out quit a bit. Good luck with this and hope all works out for ya.

 

You have to check it with a timing light. The only way to fix it if it's off is to start replacing parts, beginning with the distributor.

 

Thanks for the help guys! Got it all figured out, I just got confused from that post that said the connector needed to be jumped. I was thinking that connector needed to be jumped in order for the edu to adjust the timing! Thanks again!
