Hi Guys.
I have a 87 9000T with a 2.1L head. I need to know proper air mass meter adjustment and timing for performance as well as to pass smog?
My stock performance set up.
1) I had the air mass set at 315 Ohms (Left to right pins 3 and 6)
running 18 to 20 degrees BTDC timing and was running the adjustable fuel regulator 1-1 at 42 PSI. The car runs strong and will hold 4/5 red boost.
2) These are the adjustment I made before I smog the car, I turned
the air mass meter screw 3 turns CCW now it's reading 100 ohms (Left
to right pins 3 and 6), I set the timing to 10% and backed the fuel
pressure down to 24 PSI.
3) Can you let me know if my smog adjustments are correct or way
off and if my Track / road performance adjustments are spot on?
Any trick or tips will help.
Thanks
Dave
