Brand new SCT GTX and having problems
I paid $600 for the tuner to replace my much smaller and hard to read H&S Mini. Have a 2010 F-450 w/ 6.4 Powerstroke. Daily-driver...I don't haul anything...just like F450s. I don't run any tunes - simply wanted to monitor all the critical stuff.
Set it all up and was rather quite impressed with the sharpness of the display. Gauges look great and you can monitor quite a bit. Drove truck for several days in a row and really glad I made the switch.
Then I let the truck sit for 2-3 days. Takes a lot of effort to keep a black F450 clean so...since the weather was rainy...I drove my beater.
The next time I got in the truck, the GTX wouldn't power up. Tried a bunch of screen taps, key cycles, ...nothing! Momentarily disconnected from the wiring and then it came back on. Butttttt...now all my gauge settings went back to their defaults. Thought it might be a fluke so reset them all again. Worked fine for next few days, but again after I left truck sit unused for a couple days...same thing...had to unplug to reset and again all my gauge settings GONE.
I contacted SCT help desk via chat and was told "Yes, it is a bug...we're working on it."
Can't know for certain but I would imagine they knew about the "bug" back in November when I ordered the thing but they shipped it out anyway.
I also notice that the Engine Oil Temp and Engine Coolant Temp, the two most critical things I want to monitor right now, have a 10 degrees F differential. EOT is the higher of the two. That might be normal once the truck is warmed up, but this is at complete ambient...when the truck has been OFF for a 24 hour period. I checked it several time and each time the EOT temps starts out 10 degrees higher than coolant temp. Might be the sending unit but now that I know they have other bugs....who can tell?
Should've just stuck with the H&S, I'm now thinking.
