timing advance/retard
timing advance/retard is there anyting I can put inline with my crank position sensor to trick the computer to advance/reatard timing across the entire rpm range? ie a capacitor / resistor / inductor?- if so - what size for various degrees of timing? thanks

Or you could buy LS1Edit or HPtuners or ?????

just hack the code so when an unused i/o line is triggered a bulk timing is taken out, then you can not effect any other system. Even better make it bank select a new timing map in so say if you spray, you have a secondary timing map, because timing maps aren't flat, you don't need to take/add timing across the board, its always a curve one way or another.
where are the code hackers these days

The crank trigger is hall effect and uses a pull-up resister internally. The pattern is 24X with each 90* having a uniuqe pattern. This enables the PCM to find crank position within 1/4 of a turn. The signals are made up of 3* and 12* pulses. Check out the sticky at the top "Detailed Diagnostic Info for the LS1". All of the info is available following the link provided in that thread.
