I'm not surprised at getting close to 1700, I know it's not hard to do, but 1700+ is too hot to hold, and according to this gauge, 1700 comes on well before redline and holds that high....this gauge seems to read higher than an actual egt sensor in the mani does from whats posted up...you had said the pcm makes a calculation, so I just think it's pretty off
In my first post in this thread I noted that the PCM EGT values were consistently about 100 degrees higher than what my actual EGT sensor read. I don't understand your point. You say it's "pretty off", that was determined a long time ago. Do you think they are off by more than what I reported already? The point I was making is that we know the PCM value is 100 degrees higher than what you'd see with a sensor mounted in the exhaust manifold. Knowing this, I believe the readings are still useful. I have not received much data from others, I guess not that many people are using actual EGT sensors, but what little I've received seems to back up what I found last year.
