Just purchased a jb4!

[Brichinelo]

Dialing things back with a jb4 after coming from a tune. A jb4 will fit my needs a lot better. Can someone plz inform me of the main stats from the jb4 I should be looking for and monitoring in a log to make sure the car is running good ? And what should the hks plgus be gapped too ? Does the jb4 keep the map you use when you shut off the car ? Sorry for the fury of questions but the info is highly scattered among the web and the forum. Any help is very much appreciated. Car is still in the shop but have some things on order and just want to be ready for when I get my car back . Thanks

ignition timings 2-6 (I reckon) for logs

hks plugs don't need to be gapped, they should come pre-gapped. (though double check the gap ofcourse, iirc 0.022?)

Yes, jb4 saves the map you were in prior to
previous use.

As far as reading logs is ignition timing the only thing I should be aware of? Any other parameters that will dictate how the car is running ?

Apr, boost, how much throttle input. Don't cluster too many things

Other than what has been previously mentioned (timing 2-6, boost), if you go more exotic, such as CPI or WMI, then you want to keep an eye on fuel trims.
