How to get my Trinity to read the same as my AEM gauges.

[JimmyT]

Here is a video I just took of my AEM UEGO amd fuel pressure gauge. Is that reading on my fuel pressure gauge accurate for a stage 3 fuel pump, fpr and rail?
Also I'm trying to dial in the gauges to my Trinity but can't get it spit on. It's a close but I feel it could be closer. Would anyone happen to have the low and high values for each gauge to put in my Trinity?
How close do u have your DST reading to your gauges?
Does anyone have it where both your gauges and DST are exactly the same?

My low and high values I put in the Trinity are

AEM UEGO
Low = 10
High = 19.98

AEM Fuel pressure gauge
LOW = 0
High = 19.98

I am having similar issues in calibrating my Trinity with my AEM 30-4110. The gauge is reading spot on but Trinity is all over the place. This tel me I have the gauge wired up correctly but something is up with the DST. I've tried various upper settings, anywhere from your suggested 19.98 all the way down to 15.6. At 19.98 my AFR on the Trinity would read something crazy like 17.39 where as the gauge was still reading spot on at 14.4-14.6. When I adjusted the upper to 15.6 it was the closest to matching the gauge reading at idle. Now, during WOT, the gauge is still reading spot on in the 11.8-12.4% range but the Trinity never drops below 14, regardless of where the upper is set to.

How exactly did you wire your hot and ground? I pulled the 12V from a keyed cig lighter and ran all the grounds to the negative battery terminal.

No one here seems to be able to help so good luck. If you find out what the solution is, please let me know.

Thanks.
