when you install an aggresive chip should you advance the timing???

 

Hello, welcome to quantam physics class. Bathroom is down the hall on the right.......

pardon my humor, but on this board we actually burn our own chips and have the ability to change every parameter in the chip. The short and sweet answer to your question is tha tyou shouldn't buy an over the counter chip. They are a waste of money and you can get most of the benefit by simply advancing the timing manually.

When you can tune your own chips simply knowing what your base timing is set to is all that is needed to start tuning.

 

no. if you bought an aftermarket chip, they probably turned the timing up too much already.
the base timing needs to be properly set to what it is set to in the chip.

 

What's an aggressive chip? In most cases you should keep your distributor set at the stock value (6 degrees for most of us) and adjust your spark tables for more/less advance.

If you're getting your tune from elsewhere, keep your distributor at stock, since this is most likely the setting for which they created the tune.

Even better, tune it yourself!

As mentioned above - you ALWAYS leave the timing to the stock setting because all spark advance is handled inside the tables of the eproms.

As this post is related to tuning your OWN eproms, I have to close it.

Sorry.
