Aftermarket engine gauge recommendations

Another vote for the Scan Gauge. Bought mine over ten years ago for $139 when I was towing a 22' TT with my 5.4L F-150. When I sold the truck/traded in the TT on our 24' class C all I had to do was reprogram it for the 6.8L V-10 and mount it... which took all of about 5 minutes.

I run with the 4 way display showing average and real time mpg, trans fluid and coolant temperatures. Have never need any other displays although there are a couple of dozen readily available. Used it to read and then reset the CEL when it threw a trouble code. I'm sure the new models do even more but bang for the buck you cannot beat a Scan Gauge.

I thought the latest 2021-2022 chassis instrumentation already provides lots of information.

For our 2007 E350 chassis, many years ago I added a ScanGauge-II on top of the rear view back-up camera as shown. I tucked the wiring behind the head liner and "A" pillar trim for a professional looking installation. Needless to say, it stays put. I appreciate having it.

I personally like to show fuel-rated information including the TPS (Throttle Position Sensor) which tells me how far down I have the gas pedal. Sometimes I don't realize I have the pedal to the metal until lifting my foot. Backing up a lot on the throttle can sometime yield very little difference in speed when on a gentile many-mile incline.

I went with a phone app to monitor my trucks vitals. It's called Torque Pro and as far as I know, only works on Android phones.. It connects to different brands of ODB2 connectors..

The "gauges" in my 13 F150 don't move after they reach their 'normal' position. The only time they will actually move is when you have reached some very high temp level or if the oil pressure goes < 5psi.

I paid $5 to get the full version Torque Pro app. I think I paid around $25 for the BAFX ODB2 adapter that links to the TP app on the phone.

You can setup a lot of "PID" data that monitors actual temps and a bunch of other stuff you will never really care about..

Unfortunately, it DOES NOT monitor oil PSI or TEMP.. That might just be that my ODB2 does not have that info in the ECU for 2013?

Anyway, has worked for me since around 2018 and really helped me adjust my driving habits and how I let the rig tow in various conditions.

Good luck! Mitch

Well if it plugs into the ODB2 connection, getting the same information. Instrument panels now give far more information

I think the edge insight displays more info than the scan gauge. However, we use the scan gauge because it is smaller and less obtrusive. I already have the tire pressure monitor and the gps on the dash. One more would make the dash awfully cluttered.

The scan gauge fits nicely on top of the rearview mirror. Easy to see the parameters I want to monitor at a glance.

I used an Edge Insight for two rigs and was able to set it up to read whatever the truck was doing

A ScanGauge should have what you want. And more...
