Please forgive the almost duplicate post, but I seem to have picked the wrong place to post my previous question about OBDII scan tools. Having exercised the search function, however, I've read several disparate posts about each of the subject tools. I still find myself torn on which to purchase (or more accurately request for an upcoming birthday).
What I've taken away from all I've read is that:
- ScanGauge is the "tried and true" solution, while WatchDog is a relatively new "premium" product from an established automotive tuning company, and Ultra-Gauge is a new entry from a new company.
- Ultra-Gauge is the bargain entry, at about 1/4 the price of a WatchDog, while ScanGauge occupies the "middle ground" at just under 3X the cost of an Ultra-Gauge.
- I haven't seen much about compatibility problems with ScanGauge or WatchDog, while Ultra-Gauge causes problems with 2004 Tacoma ABS systems and is listed on the manufacturer's site as being "Confirmed Not compatible with 6-lug Tacomas with ABS" (like mine).
- WatchDog offers free upgrades via the Internet, while Ultra-Gauge requires a trip back to the manufacturer for its free upgrades. ScanGauge requires a trip back to the factory, and has a cost associated.
- Ultra-Gauge and WatchDog both include a couple of different mounting options, while ScanGauge includes only velcro strips.
- All offer a plethora of gauge capabilities, but only ScanGauge and Ultra-Gauge advertise the ability to read/reset CEL error codes. I'm guessing that means WatchDog can't read or reset them?
I tried to put most of each device's features into a spreadsheet, to facilitate an "apples-to-apples" comparison (attached). GREEN lines list capabilities that appeared "equal" to me. YELLOW shows ScanGauge "advantages". BLUE shows WatchDog "advantages". RED shows Ultra-Gauge advantages.
All of this said, I'm interested in hearing what my fellow 1st Gen owners think, which one you prefer, and (most importantly) WHY you prefer it...
