Its been awhile since I played with the timing.....

I pulled the spout, set it to 12 degrees (idle), shut it down, replaced spout. I then checked the timing....it went to about 20 degrees (idle) with the spout back in place.

Is it supposed to do that ?

 

Yep................. All you set was the base timing, the computer does the rest..

 

Thank you my friend !

 

Yep, when you accelerate the truck's engine it will even reach up to 30 deg.

 

by coincidence, i just did this tonight also, before starting anything... I checked my vacuum and found it at a steady 18 inches. My vehicle is a 1995 F150. I cranked engine to bring it up to temp, unplugged SPOUT then took positive cable off battery. I then proceeded to adjust base timing. adjusted it to what i think is 10 deg BTDC. The vacuum increased to 20 inches steady needle. I did not turn ignition off, just Plugged SPOUT back in and connected battery cable... took it for a test drive (cpu learning session) but I am having some serious valve pre-detonation. Did I do something out of sequence... or possibly have another problem. My reason for even looking at this was the truck was feeling very weak.

 

I must be misunderstanding what you said, but, May I ask how in the world did you adjust the timing with the battery cable off??? The engine needs to be RUNNING to set the timing..

 

Oh yea... i cranked the engine before removing battery cable... the manual said the cable had to be removed to get CPU to reset. so truck was running.

 

That's a good way to burn up every electronic part (radio, ignition module, etc.) on the truck.. The voltage can go VERY high with the battery disconnected while the engine is running..

You pull the spout connector, start the engine, set the timing, turn off engine, plug in spout connector. THEN, disconnect the battery "IF" you want to, but without the engine running.

 

Would setting the timing fix the ping noise I have in fourth gear in the 2000RPM and below range.

 

If it was off to start with.. Normal setting is 10 degrees from the factory, some people run the timing as high as 14 degrees without problems.. I run mine at 13 degrees, it seems to perform much better than stock..

 

I don't notice the noise until I shift into 4th gear and it sounds like a tinny noise until I get about 2000 rpms after that I don't notice it.

 

Can't hurt nothing by checking it....

 

Thanks for the help I not a mechanic so I appreicate the help that I get from everyone.
