<<For those of you running a high compression 5 cylinder in your CISE 4kq, I
have a few questions.  What are you doing for fuel mixture and timing
settings? >>

IME, set the CO to about 8mA or so, pretty much same as stock, set initial
timing (with the vacuum sensor) between 6-10 degrees BTDC.  Frankly, its a
great fit, no knock sensor needed.

<< Did you bias the mixture a little richer?  How much spark advance>>

No real need to set the mixture richer, just reset the initial CO, everything
will be fine.  See above for advance, basically as much as you can get
without pinging.

> <<can you run before it knocks?>>

No knocking problems, even on crappy CA gas.  Of coure, you'll want to run
premium.

<<  W7DTC, WR7DS, or something else? >>

Stock is fine, whatever it is.

<<Do you > still have the vacuum advance hooked up? >>

Absolutely

<< Did you encounter any problems at > all getting it to run on CISE without a
> knock sensor?>>


Nope, the CIS can easily handle the extra power, and as far as knock sensors,
they are saftey devices, not tuning devices, if the car is tuned properly,
there won't ever be a need for it.
