ScanGauge II firmware upgrade

By: on 19 August 2019
I had been using a ScanGauge II in my 2010 diesel Pajero for over 5 years & as I tow a caravan was monitoring the ATF temperature & water temperature along with voltage & turbo boost. I recently upgraded to a 2019 LC200 & needed to get the firmware upgraded to the latest version to do the same monitoring. Excellent turnaround time of less than a week. Gauge is easy to setup with LC200 codes. So many parameters to choose from - but its now happily monitoring ATF at the torque converter & ATF in the pan, as well as water temperature & voltage.

Great Service

I've had a ScanGauge2 for some time now & find it a very useful addition to my vehicle. The ability to monitor the many functions in the workings of modern vehicle makes it invaluable. When it began to have problems with the cable connections I contacted Fuel Economy Solutions & spoke to Boris. He was most helpful & suggested I return the gauge to carry out some tests in their workshop. The gauge was repaired quickly, returned within a very short time and the cost was very reasonable. Throughout this period there was feed back from the company letting me know the status of the repair. This was much appreciated. I would certainly recommend Fuel Economy Solutions & ScanGauge, the after sales service is exceptional.

Upgrade worth every cent

I finally upgraded 14 year old Scangauge II (yes, you read that right, 14 years old!). $50 and 3 day turnaround. X-Gauge customised by Boris to read my MY13 Toyota 86 GTS oil temp. Could not be happier. The SGII is awesome and small enough to give essential real time info in line of sight. Perfect.
