Timing adjustment? Options

[bdog_v]

Hello I adjusted the timing on my new 133,000 mile 94 2.2 litered celica today. The chilton manual was no help as it did not say were to set the timing. Also I can't find the sticker by the motor that says were the factory wants it set so, here is what happened.

-Warmed the car up

-It was idling at about 600rpm

-I checked the timing and it was only at about 5-6 degrees
(It looked like the timing had never been adjusted)

-So I set it at 9-10 degrees as I believe someone on here told me that was the factory spec.


-Now is 10 degrees the factory spec for timing?


-What rpm at idle should it be at, around 600rpm?


-Do I need to reset the computer for it to adjust to the new timing??? and disconnect the battery for ten minutes or does it adjust while driving?


-Also on these motors is it easy to here them ping? AS I cannot here any pinging coming from the motor under load at 10 degrees........ I don't want to hurt the motor by going too far advanced......


-Anything else that I needed to do to properly time this car ??? THanks guys......

1. start car and let it reach operating temprature. i suggest driving around for 2-3 miles.

2. turn car off, jumper connectors E1 and TE1 with a paperclip or a jumper wire.

3. at this time your check engine light will blink and you can read stored trouble codes

4. at this time you can check your base timing since jumping the connections disables advance and retard by the ECU. also at this time you can set timing by slewing the distributor.

advancing timing can produce some gains in the middle and low power band, but negatively can impact the high rpm performance, making the engine feel "flat".

i advanced my timing and i dont think i'd wana go back now. i lost some on the very top but by the time im there, the trans is shifting to the next gear. my powerband is now very smooth through the gears and my highway mileage went up also.
