FIRST OFF I HAVE SEARCHED THE INTERNET FOR MY ANSWER...
SEEMS EVERY THREAD ENDED BEFORE AN ANSWER WAS REVEALED

This is with an OBD2A ecu

With that said all I need to kno is if I Advance Cam timing will it advance ignition timing?

To prevent a simple yes or no answer, I will be needing a brief explanation as to how obd2a reacts to these adjustments and how I can counter the ignition issue beings the distributor ISNT adjustable

 

loosen distributer to move forward or reverse to advance/retard timing.. cam timing is different then ign timing

 

The answer is yes. Moving the mechanical cam timing will also change the ignition timing. Think about the connection of the intake camshaft to the distributor drive! Base timing changes with sprocket advance and retard. To compensate you will have to reset the timing after every intake cam sprocket adjustment.

 

How can I reset the timing after every cam sprocket adjustment.?

 

If you advance the intake cam timing, you will need to retard ignition timing in the same order to maintain a specific ignition timing angle.

Degreeing the motor correctly would catch excessive ignition timing, and retarding would be required to prevent detonation or non-ideal combustion events.

Adjustable cam gears are only required with aftermarket cams (since they may or may not match factory open/close events) or if the head or block are resurfaced which will affect the timing belt position.

 

Damn... I appreciate the reply but I need answers..
I have an OBD2A ecu.... CANNOT JUST TURN DISTRIBUTOR!!
how do I adjust ignition timing with a non adjustable distributor..?

 

I believe timing is set via the ecu on your particular setup.

 

That's what I believe is correct...
just cant believe how many people point towards turning the damn distributor for everything...
its OBD2A

 

I believe some early OBD 2 Hondas had manually adjustable timing. It would be easier to answer your question if you simply gave the year,make and model of your setup.All ECUs are not created equal and respond differently,but for the most part they will react to an advance in cam timing by retarding igntion timing and or going into open loop.....

 

1996 Honda Accord Ex 2.2L F22B1Vtec

 

All factory Civics and Integras have adjustable distributors, as well do Accord 4 cylinder and 6 cylinder models prior to 2003, and CR-V B20's as well.

DIS ignition systems may retard ignition timing based on a known knock sensor profile, which is why it exists at all: To vary ignition timing in the event of unexpected combustion events.

The PCM will add timing according to its programming assuming that base timing is correct. If base timing is not corrected due to mechanical changes that increase compression, detonation may result. The knock sensor is the only feedback Honda's have to determine if combustion was ideal, or not. This will also be reflected in the crank sensor as the crank will speed up or slow down in response to a non-ideal combustion event.

Software improves "generally" with every update, if any. Unfortunately the updates you may or may not require may not match the changes you have made, which is the entire point of aftermarket ECM's (AEM EMS, etc).

 

Im going to search the Tuner Directory thread on the Engine Management and Tuning forum. I now have a Hondata S300.
My engine model doesn't have a knock sensor...
Also my distributor physically cannot be adjusted. The bolt holes are the same size as the bolts and will not allow any movement for adjusting.

 

Not quite. Obd 2 Accords (1996-present) do not have adjustable distributors, which is why I asked him for his specific MMY.

The distributor is not adjustable. You can change nothing on a stock Accord.

I have not used the S300 program,and did not even think it was available for your vehicle. Have you verified that it will work? If so then I imagine you can change the timing with it as I do know it to be a pretty comprehensive program.


But simply advancing cam timing and ignition timing will not net you any performance gains.

 

Derr, you still have to turn the distributor to get base timing correct! This means elongating the bolt holes in order to be able to turn it. It doesn't matter if it's non adjustable from the factory, it must be modified in that case. NO MATTER WHAT.... YOU HAVE TO TURN THE DISTRIBUTOR. This is why people are saying that, irregardless of being OBD2 or not! What are you not understanding about the physical connection between the distributor and the camshaft? I'll say it one more time, if you change the cam gear timing, you MUST correct the base ignition timing, no if/ands/or buts about it. So get the fact that it's a non-adjustable distributor out of your head, you must make it adjustable or.... leave the cam gear alone.

The pcm only adjusts ignition advance, it cannot affect base timing, that is the physical connection between the distributor to the cam to the crank, the computer cannot adjust that for you, you have to physically make it happen. It's pretty straitforward and easy to understand so don't get all pissy when people keep telling you that you have to turn the distributor, they're 100% right. You're just looking for an easy answer that would prevent you from having to modify the distributor bolt holes; well, an answer like that doesn't exist, accept it.
