Review on ScanGauge SG2 II Ultra Compact 3-in-1 Automotive Computer - Real-Time Fuel Economy Digital Gauges, Black, 5 Inch by Julio Solano

Excellent tool. I now have access to my 13th Tacoma's transmission temp. There are actually two temperatures, one in the sump and one after the torque converter. There's also MPG, intake air temp, coolant temp, and more. The device fits perfectly with Velcro on top of the steering column. A HUGE disappointment is that they sent me a device with firmware version 4.42 which is two versions out of date. The current version is 4.5. This means I can't determine the tire pressure. How cool would it be to drive and see the tire pressure! I have a comment on this, they have TPMS but the only thing you get is a low pressure warning. It doesn't tell you how low or what tire. ScanGauge is one way to fix this. I can send the unit to ScanGauge and for $25 they will upgrade the firmware. I must think about it. I've already spent some time routing cables and using velcro so can't bring it back at the moment. Spring.
