WTH happened to my fuel pressure?

[boosthead]

I borrowed a friend's Dashhawk to validate that I wanted to buy one. I did some monitoring of boost, kr, a/f for about 10 miles then stopped and used my Hypertech to calibrate the MAF for my Cobb intake. After hooking up the DH again, my fuel pressure is reading a baseline of about 3000psi and like 16000psi under load. I thought it might be an issue with the HT calibration, so I changed it back to the stock MAF calibration and still have the issue.

Did I break my buddy's dashhawk some how? Is it possible I inadvertantly changed a setting on the DH? All I did was unplug it, update with the HT, then plug it back in. Help?!?!

there are several ways to read fuel in the DH, you want DI pressure

I did some further checking and it is listed as DI. I guess what I don't understand is why it was reading correctly, then after no changes other than the MAF calibration (then returned MAF calibration to stock) it's reading incorrectly.

I don't know what happened, but I checked to confirm the DH had the correct software, then hooked it up again and it's working fine. I'm showing around 425di at idle and 1600-1700 at wot. I tried logging for the first time and realized I logged for too long and the graph was very hard to read. Can you parse out portions of the log to display, or do you just have to log for shorter intervals?

You can zoom in on any part of the log too look at. Its one of the top buttons, you can either just zoom in or select a portion to zoom in on.

I tried that function with limited success. It zooms in, but I cant seem to specify where or how much to show. I guess I need to read the manual.

Sorry it is the rectangular button next to the cursor icon.
