I got a lot of stuff in my car but this is actually the ones that you can tune...

Vafc
Cam gears
Fuel pressure regulator
and of course ,timing

I'm just wondering if there is any specific order to tune them (Ex. cam gears first,vafc second etc etc)?

Set your timing and fuel pressure to near stock settings. Make a baseline run. Read the graph for spikes or irregularities. Check your A/F logs. Find out where you're running rich or lean. Adjust your AFC accordingly to compensate (lean out the rich areas, richen up the lean areas) If you're N/A, keep timing near stock, or advance at the most a few degrees. Keep in mind your cam gear changes also indirectly affect ignition timing too.

Try to keep changes to a small percentage (around +/- 5%) Run it again and read the graph and A/F logs. That's about it!

 

nicely said

 

SO YOU ARE TELLING ME THAT I SHOULD MESS WITH THE VAFC FIRST AND THEN WITH THE SPROCKETS(DEGREES)??

tHIS IS HOW I GET IT,IS THIS CORRECT??

1. STOCK TIMING AND FUEL PRESSURE= BASELINE RUN
2.ADJUST FUEL PRESSURE
3.WORK WITH THE VAFC(RICH,LEAN,VTEC CROSSOVER POINT ETC)
4.AND THE LAST ONE,WORK WITH THE CAM GEARS

AFTER ALL THOSE 4 STEPS SHOULD I GO YO THE SECOND STEP,THIRD STEP ETC UNTIL I GET BEST TUNE??

THANK YOU FOR YOUR HELP
