Re: Timing, Timing, Timing (Bans25)
If you don't have a timing light in the future you can always adjust your timing by ear...I have had to do it several times and it would surprise you how accurate you can be..Mark
I think on older non-computer controled cars this was ok, but on FI cars I would not suggest it. The knock sensor will pick up knocks that you may not be able to hear, and when the ECM receives knock count it cuts back the timing by a large margin (I think 10+ deg) so I would use a timing light.

:iagree: Up to 20 degrees total pull in a stock chip.

Glad you have it all figured out Chuck.
I know that you pulled the intake a time or two as well as the distributor. The smallest retard/advance can make HUGE differences in performance(As you've found out).
Depending on the chip timing, you'll have to fool around with SOTP to determine which works best. I think Gabe set the record for doing that LOL.
It might like low, it might like high. Mine never liked what everyone elses had. . 6 deg initial. I was best at 3.
Good luck and let us know how it does. :cheers:

Chuck: Something else you may want to try is.....set your throttle position sensor at somewhere between .62 to .65 volts at idle. This with the 8 BTDC timing will give you some impressive throttle response!

Re: Timing, Timing, Timing (Sam Lam)
I've had my fuel pressure back up to 43 PSI's for some time now. I also have TPS sensor set to .65.........all seems well
Gabe, I may pay you a visit to see if I'm getting any knock counts at 8 BTDC.
