OneGauge sent me another update today and everything is working now. The temps are still slightly slow, but they're much better than they were. They look like they're updating every few seconds now at least. AFR is still a bit slow. They're looking into that more, but so far stumped as to what the issue could be because they said Haltech comms are always fast. Full tank reads a bit high still but I honestly don't care at this point lol, at least it reads zero at empty. EGTs and the ambient and intake temps were a few degrees off from what the ECU read when the key was to accessory before starting it, but I'm not too worried about that especially since EGTs will be so high anyway, a few degrees doesn't mean much at that point. My fuel pressure is reading a bit low because I guess the graph I used for the sensor I'm using wasn't perfectly accurate, but the gauge matches the ECU. I put a mechanical gauge directly off the FPR where the pressure sensor is mounted and the gauge reads 43 while the ECU says 36ish. Pretty much all the gauges (other than the temps I mentioned before) read spot on or within a number of what the ECU says. The odometer is constantly running codes currently, OneGauge is using that info to troubleshoot the slow gauges. Of course after all of this is sorted, I still need to finish the gauge hood with filler and paint. I didn't see the point in doing that while I was still removing the dash piece on a regular basis. My interior has been partially disassembled all summer because of this.

Well, it turns out my boost issue is not fixed. I got the same 'trigger reference error' CEL again tonight, and on the second pull it even killed the engine again.

Another thing I forgot to mention about the fuel temp reading. I was talking to Brett and he said it could be that the flex fuel sensor failed and the readings are backwards now, indicated by the temp starting at pegged out on the top end and dropping as I drive.
