timing

 

sorry for that, here`s my real post.

I have a Camaro 5.7 TPI `88 Iroc. I live in Poland ( It`s in europe ). the gas is 95, 98, 101> octane. I have the timing set to advance 9 or 10. Is it good? I know the standard is 6, but thats for fuel like in us. What do You think about it?

 

Well Ive got my Lg4 at 14*, if You can belive the Dampner.

9 Is not Unreasonable at all.

Go untill It Pings, then back off a degree or Two. )


Its Not really Initial Timing that matters anyhow, Its total. But thats A WHOLE nother can o Worms And I dont have the will to explain it all here, I dont even fully understand it enough to explain it clearly. Go look at the tech articles one guy does a good Job there.


You have to really Want to learn tho, Its not exactly a quick read.

I remember reading this somewhere and here's how I understand it:

The ECM (also know as the computer) doesn't know how much initial timing has been dialed in using the timing light. (Probably doesn't care either).

All it does is receive signals from the distributor and add additional timing based on the information that is programmed into the PROM (Programmable Read Only Memory or "chip").

So if you have a maximum of 40 degrees of timing in the PROM and you set the initial timing at 6 degrees, you'll have a total of 46 degrees of timing (Cruise conditions/good gas mileage).

If you bump the initial timing to 8 degrees, now you'll have 48 and so on.

The amount you set with the timing light is added to the PROM programming throughout the entire timing map.
