I use EOT/ECT/TFT (VLT/FIA) religiously and TFT saved my bacon on a ski trip last weekend. TFT went up dramatically in ~5 miles and when I pulled over there was tranny fluid pouring out of the truck - Long story short, low pressure hose rubbed through, quick trip to a mech for a bush fix & I was able to continue the trip.
FYI if you ever have issues in or near McCall Id, Sharlies Auto Repair are awesome!
1der, that is the same place I mounted it. I have set up tranny temp, engine temp, RPM and MGP. I like the small form factor of the gauge and it works perfectly.
