The tool features a unique, patented all-in-one screen display and an LED display for quick emissions status checks. Meanwhile, the 3100's automatic refresh updates data every 30 seconds when connected to the vehicle, offering an easy way to verify repair completion. The tool communicates with all OBD II protocols, including CAN (Controller Area Network).

An internal battery stores the latest test results for later review and analysis, and to accommodate future vehicles, the tool is fully upgradeable via a standard Windows-based PC. Equus' OBD-PC Link software is included with the tool, making upgrades a snap.

Payed for itself on first use, December 2, 2007

I bought INNOVA 3100 about 2 weeks ago because my MIL (Malfunction Indicator Light) was on. Plugged it in after reading the manual. It said Oxygen Sensor Bank 1 Heater was bad. Called Mitsubishi dealer: Cost of part $317.43 plus 30 minutes of shop time. Looked up a replacement on internet at a cost of $37 plus $10 for a special socket to remove and replace. Another $7 for a Sears crimping tool and I replaced the part and saved over $228 plus I have the INNOVA to use over and over again.

Some reviewers have said that they can't save reports in their computer. There is now a button on the INNOVA supplied program to "Save to File." This makes a test file of about 17 different test results. It is in .txt format and you can copy and paste it into a Word document if you want to dress up the format.

Both the PC CD and the tool worked fine right out of the box. The unit comes with two cables: One to plug into the OBD2 socket under the dashboard of your car, and the other to plug into a USB socket on your PC. The INNOVA has built in memory to save readings obtained during a drive and then subsequently provide the data to your PC.

I am VERY PLEASED to give this unit FIVE STARS.
