Dude, Datalogit is so inexpensive and so powerful relative to the expensive and useless garbage that does nothing for speed that ya can't afford not to have one. Bang-for-buck factor is way, way up there. It's a true "race" part. Buy one!

No hiccups, but I am deprived not running a 3 bar. If we can get Steve Kan down here next month, I'll probably join in for 3 bar switch and street-tune.

where did you get your datalogit and how much? I don't know much about it but do you have to activate that software or something? I read that some people were waiting months to hear back from New Zealand to activate the software or something.

I believe RP, Gotham, RX7 Store would have them starting at $340. Online support at Yahoo! Groups. That Datalogit is in New Zealand is not an issue as the product is heavily supported because of its wide use.
Comments on my maps and settings are appreciated.

Assuming you are using a stock map sensor since your settings 3 are stock, and using the calibartion of my own stock map sensor; this is what I see.
P16 is for 12 PSI boost.
P17 is for about 13.5 PSI.
P18 is for 15PSI.
P19 is for 17PSI.
P20 is above 18PSI which you can never run.
Your timing barely changes for these rows when you are on boost.
It think your timing above P17 is too HOT. Normally you reduce timing about 1 degree for each 1PSI boost increase. From P17 to P19 is 5 PSI but your timing does not decrease for most of your power band. And only 1 degree in the higher revs where timing is less critical.
What rows have you actually tuned for knock levels?

Chuck - I have read your post regarding the need for calibration and integration of the PFC with MAP sensor voltage (PIMv) and the boost gauge due to the fault inherent in PFC software. That and what you've just pointed out shows me that I have setup issues (even w/o the Apex-i software error fault) w/ the stock MAP sensor.
If I understand correctly, I need to calibrate these three components (PFC, map sensor, and boost gauge) to optimize map sensor's PIMv resolution so that I'm scaling the Map Reference in Settings 3 using actual values derived from the stock map sensor capability. P20 value should really be no more than 21850 / 1.185 BAR / 17.2 psi? Or 18 psi?
And then, I should pull an additional degree or two of IGL in the boost region while maintaining proper IGT split from rows of 14 psi and above?
Confession - I don't own a WBO2 yet. I was street-tuned on a cold, dry day and I run fat as days warm up.

Part of my cailbartion:
BOOST---- PIM ABS---PIM V----- Boost Gauge
115--------21853-----4.901------18PSI
115--------21821-----4.896
114--------21821-----4.896
114--------21797-----4.892
114--------21773-----4.887
114--------21749-----4.881
113--------21725-----4.876
113--------21693-----4.873
113--------21669-----4.868
113--------21645-----4.862
112--------21565-----4.848
112--------21493-----4.833
111--------21413-----4.818
110--------21309-----4.798------17PSI
I have my row 20 set at 21850 where I take a lot more timing out and add a lot of fuel. This makes it a safety no blow row!
I have my rows by 2psi increments and remove 2 degrees timing per row.
