Ok, for the 4th time you have not answered that question and I have seen that you have posted today and had a chance to see my question yet again. I can only conclude then you must be using short sweep gauges in your comparisions. While you can still do a somewhat accurate comparision with short sweep, you have to be looking at your readings a little bit more to make sure you get readings at the tick marks so you know exactly what readings your short sweep gauge is giving you.
Also, technically speaking it's not digital gauges that I think you have a problem with, it's the OBD-II gauges that you have difficulty with. There are digital gauges that use external probes but they just have a digital display. I might be wrong, but if your just talking about digital guages period then you would have that issue as well.
Normally I wouldn't be this
adament on knowing, but given that my comparisions between the DashDAQ and the long sweep analog gauges that I have, the only difference was the 2-4 degree TFT difference and the DashDAQ was on the hotter side(which I would rather have it be on the hotter side then the colder side if it was going to be a little off, but 2-4 degrees is neglible in my opinion). Also I'm not disturbed by the difference in TFT readings is because if your gauge is in a spot that you don't know exactly what that blank spot means or that tick mark means, you could be off in your judgement 2-4 degrees(or more if it's short sweep and in a blank spot). All the other gauges that I used were on the nose(EOT and ECT being the more important ones I concentrated on). Couple that with the fact that you never told me how you made those comparisions on your own(if you did, but I'll give you the benefit of the doubt on that one), I can't give as much credence to your statement especially since I've tried several times to find out what evidence you had that lead you to your opinion and no response.
Now, I won't ask you again how you came to that conclusion since you obviously don't want to mention, but I can't help but question it without knowing your train of thought when it differs from my own observations.
