how do you adjust timing on a 94 Z with the opti-1?

 

Very carefully! Seriously, the timing is computer controlled, there is no manual adjustment possible, but it can be done by reprogramming the PCM. The PCM advances timing till it gets a knock signal from the Knock Sensor, and then backs the timing off a bit, if it sees no more knocks it advances the timing a bit. Keeps doing this till the timing is advanced just below the knock level. So there is really no need to mess with the timing. Also automatically adjusts for different octane ratings.

 

thx for the reply... i was wondering if you can maybe delay or retard the timing slightly.. just an idea a friend of mine and i had, to make it sound a little meaner, or if i ever get my 100 shot hooked up... just an idea..

 

If you get that NOS system get the controler with it it will adjust the timing and fuel.
