I really need to log in here more often.
So, I've been tweaking my cold/ram air intake a bit to try to generate a bit of positive pressure to help with mountain driving, and found out things about the car I didn't previously know.
I played around with my UltraGauge some and found it actually does give readings for MAP (on a US model 2014 5 speed), and it seems accurate. It gives about 14.6 PSI when the car is off, which is correct for atmospheric pressure, depending on elevation. It also gives readings for "Wideband Bank 1 O2 λ," when I thought the car only had a narrow band O2 sensor, but these DO in fact come with wideband sensors!
While driving, I can get the MAP to show near zero vacuum with as little as 60% throttle at highway speeds, so I'm wondering if I need to have the fuel maps changed. However, since I just discovered the AFR gauge a few minutes ago, I haven't driven it yet to see if it does in fact need a tune, but I'll be driving for a couple hours here in a bit.
That being said, I still do want to get it tuned to get the MIVEC to close off the valve overlap at a lower RPM to make it easier to climb hills, so I'm hoping to find out what tuning options exist for US market cars without breaking the $1000 mark. I know preset tunes exist in the Philippines, and you guys over there have done some amazing work.
Update: According to the O2 sensor readings, it's actually running rich at WOT at about the proper AFR for maximum power, somewhere in the neighborhood of 0.86.
So, it doesn't really look like I need to mess with it much, actually.
