ScangaugeI for pre 96 OBDI
 

I was just wondering if there is any place that still sells these? I was on gasgaugeII website and there is no mention of the GasgaugeI.

I was wondering what you guys (pre96) use for getting the MPG #'s other then dividing miles driven by the amount of fule added.

Thanks in advance,
Ravi

^That's exactly what we're doing. pre-ODBII vehicles are too diverse, every maker has their own interface system and they aren't the same so you can't make a device that works in them all. some maybe..definitely not all.

Scanguage 1 was ODB2 as well.

I use the odometer (with GPS correction because of my one-size too large tires) divided by fuel for my gaslogs. That is my real MPG benchmark because the ScanGauge is very reliable, but can get it's settings screwed up. The ScanGauge needs the odometer for adding tank-to-tank correction values, so the odometer is still the source.

For me, the ScanGauge is a real-time *relative* barometer, where I am competing against myself.

For pre-96 vehicles you can use a supermid by yoshi , or if you have an onboard computer you might be able to do the DIY MPG Gauge:

Both just need to be tapped into the injector lead and the vehicle speed sensor lead.

I've found the Scanguage to be more of a teaching tool than anything, and a 'gee-whiz immediate feedback system' second. Now that I have driven with it, I know what works and what does not, and for the most part, the same techniques are generally adaptable across most vehicles.

The only thing I really use it for now is to measure drafting efficiency. While I don't tailgate or even follow at a distance that's unsafe, it provides instantaneous feedback as to whether it's really worth holding that 2 second gap to the next vehicle or not. Aside from that, it's just entertainment.
