I think the Pa is the metric unit for pressure (Pascal, old dead dude). But the "hk" part is interesting. ..looks like "hecto kilo" (aka hundred thousand) a combo of metric prefixes. (there's no standard nomeclature, but most countries do combos, so try not to blame them!) According to here and here there are 6.895 kPa per psi. So 15 psi = 103 kPa = 1.03 hkPa. Considering the photos of the LED on the blitz webpage, this looks reasonable, but who the heck runs at 33 psi? (this is what you get after converting 2.30 hkPa "peak" warning as pictured on their website.) ...Well for all I know, maybe race cars do; this turbo stuff is still new to me.

..anyway, looks like, unless you wanna go metric, you'll have to carry a calculator in the glove compartment. Or maybe you can mount one in-dash. How fast can you divide by .07?

By the way, I can answer my earlier question about the DTT: according to OptAuto it does have an auto timer setting, based on turbo use and engine run time.

I made a table for you guys for this formula to convert hkPa into PSI. The engineer I work with helped me out on this one. You know engineers and books.

PSI HKPA
14 0.966
14.25 0.98325
14.5 1.0005
14.75 1.01775
15 1.035
15.25 1.05225
15.5 1.0695
15.75 1.08675
16 1.104
16.25 1.12125
16.5 1.1385
16.75 1.15575
17 1.173
17.25 1.19025
17.5 1.2075
17.75 1.22475
18 1.242
18.25 1.25925
18.5 1.2765
18.75 1.29375
19 1.311
19.25 1.32825
19.5 1.3455
19.75 1.36275
20 1.38

Hope this helps.

..just a thought.. maybe it can show pressure in psi. Could be something as simple as a setting. May be prudent to PM someone who's got one.

Antman: I hate this answer whenever I get it, but did you try a search on i-club? I know you're in Australia, but there's a lot of STi gear-heads over here. On i-club I even found a pic of a FATT install almost flush right by a guy who went nuts with a Dremel tool (exactly like I was wondering about!). Doesn't look as good as prey747's job, tho. Best of luck..

I had mine installed a while back. And I don't think there is an easter egg thing on this TT to switch to PSI. It was annoying at first but I ended up going with this for while and now I'm use to it. I know 1.17 would be my warning setting on my TT and it would go off everytime I reach or be over 17psi. I turned down my MBC a bit to keep the pressure under 1.12 since then.

I also added my little table in an Excel format...
