1997 Honda Insight

I wanted CS2 to get eyes on my trans temp in my 1997 Ford Powerstroke XLT when I am hauling my camper. When the product arrived (a couple of days before I was expecting) I hooked it up to my computer per the instructions. One easy to follow download and twenty minutes later it was ready to go into the truck. I went out and plug it in (note: the OBDII port on my truck had a black cover on it and was located on the passenger side of the transmission hump under the dash) it would not power up. Hit the trouble shooting guide and it said check the cigarette lighter fuse. Bingo that was the culprit. For reference on my truck it is the #16 fuse which is the fuse in the upper most right hand corner of the fuse box under the steering wheel. So far I have been happy with the product. I have eyes on the trans tempt and new goal to see my truck produce 20lbs of boost (note the CS2 insight is only a monitor and will not help me get closer to this goal but it will let me see it when it happens). I was also pleasantly surprised with how stout the window mount was for the unit. It solid and holds the unit steady allowing you toggle threw the menus with one hand. 496507

I love the Edge Insight. Shows me every vital of my truck that I need/want to see when hauling our camper and towing our boats. It was just what the doctor ordered.

Honda Insight

I bought this to replace a 10-year-old Insight that finally gave up the ghost. This is a much needed update and I'm very happy with the final product. Keep in mind, this is only a gauge unit, not a performance programmer. 228555

  • Can an Edge Tuner Be Transferred From Vehicle to Vehicle
    If you are referring to the Edge Insight CS2 Comprehensive Gauge Display part # EP84030 or the Edge Insight CTS2 Comprehensive Gauge Display part # EP84130 then yes, these can easily be transferred to any vehicle post 1996 with an active OBD II port. The reason for this is that they are just a comprehensive gauge display, they will not actually write anything to the vehicle's ECU. However, if you instead have a device that does modify the vehicle's ECU like the Edge Diesel Evolution CTS2...

  • Will Edge Insight # EP84030 Adjust For Change in Tire Size and Addition of Cold Air Filter
    The Edge Insight Gauge Display # EP84030 will allow you to enter the information for a different tire size and will show you the updated parameters based on the new size. However, after speaking with my contact at Edge, the addition of a cold air filter cannot be added to this item as it is strictly a monitor and will not enhance the performance of your 2001 Nissan Frontier. At this time, we do not carry a performance-enhancing chip for your vehicle.

  • Installation Instructions for the Edge Insight CS2 # EP84030
    The Edge Insight CS2 # EP84030 is a fairly easy install. The most difficult part is routing the wire from the OBD-II port under your vehicle up to your windshield. After that you will just need to attach the window mount to the window and then install the gauge display itself. As you can see from the attached photo that I snapped of the installation instructions, the wiring can easily be routed on most vehicles by simply removing the side panel. I have attached a link to the installation...

  • Fuel Economy Gains in 2002 Ford F-250 7.3L from Using a Performance Tuner
    The two Edge products you referenced, parts # EP84030 and # EP85100, are fundamentally different. The Edge Diesel Evolution CTS2 Programmer # EP85401 is both a monitor that displays engine parameters sent through the OBD-II port, and also a performance tuner that can increase your horsepower and torque by altering your engine's tune. This unit is a fit for your 2002 F-250 Powerstroke. The other unit # EP84030 is only a display - it does not re-tune any engine settings. The way these...

Although keep in mind that this monitor is specifically designed for the F-350, so while it will work, some of the displayed parameters may be different on an F-650.

    The Edge Insight Comprehensive Gauge Display, # EP84030 will monitor the turbo boost. It will read this information through its connection to the diagnostic port, no other attachment would be necessary. I have confirmed this with the Tech department at Edge. Keep in mind that the Insight is a Gauge Display only, it is not capable of altering the engine tune. To actually alter the tune, you would need the Edge Evolution, part # EP85300 or the touch screen version, # EP85400. This combination...

  • Will Use of an Engine Performance Programmer or Monitor Void the Manufacturer Warranty
    Use of an engine performance tuner or monitor will NOT automatically void a vehicle manufacturer's warranty.

  • Why Would an Edge Product Installed on a Truck Not Have Power Level Adjustments
    Since you said you couldn't find a power level option on the Edge programmer you have on your 2008 Ford F-250 there is a great chance you actually have an Insight Monitor like part # EP84030. This product only allows you to look at various engine parameters and has no programming capabilities. If your truck is a diesel you would want the part # EP85400 for a programmer/monitor.

  • How to Mount the Edge Insight CS2 and CTS2 Display on a Volvo
    The best way to mount the Edge Insight CS2 Gauge Display, # EP84030, or the CTS2, # EP84130, in your 2008 Volvo V50 is to attach the suction mount to the windshield. Edge does not make a custom mount for Volvos, so using the suction mount is the way to go. Most people will mount the monitor just under the rearview mirror, but you can also mount it on the far left side of the windshield for minimal visibility obstruction.
