Problem with Pyro reading on H&S Black Maxx
To anyone who may know...
Tonight I installed the H&S Black Maxx on my truck as well as a different exhaust... the 5" stainless exhaust (downpipe back) recommended by my H&S dealer with the DPF/DEF deleted. Everything is working as planned, no error codes, except the Pyro reading. The H&S manual indicates that with the 6.7 Powerstroke, you don't need to install a Pyro, as the H&S chip will read the built-in pyro from the factory.
At first, it was reading zero on the exhaust temp, until I switched the setting in the Black Maxx head unit to use the factory pyro. Then, once I did that, it immediately started showing the exhaust temp reading at 2700deg F. I drove the truck for about 30 minutes, ranging in speed from 20mph up to 80mph, and the exhaust temp readings remained pegged at 2700, even after the truck cooled down and was powered off.
I've tried removing the Black Maxx head unit, restarting it, etc, but with no difference. It didn't seem to matter whether the defueling settings were enabled or disabled. Not sure why the factory pyro is reading wrong in the Black Maxx.
Anyone have any experience with this? I'll try to contact H&S support too, but I don't think they're open over the weekend. Except for that one small difficulty, I love the programmer so far!!
