Monitoring Devices
My van is equipped with a feature that shows me my avg MPG over a given time period. Does anyone know of an aftermarket device that can be installed that would will give you "real time" fuel usage data?

Re: Monitoring Devices
I had to look it up in your owners manual myself to believe it. GM used to include instant fuel economy in their display. I guess they removed it after spending too much time having to explain to people why it varies so much.
The venerable ScanGauge II will do the job and costs $170. I have one and am happy with it. Recently some decent competition for it came out in the form of the $60 UltraGauge which got a good review from a member here on gassavers.org. I wish I had two OBDII vehicles so I had an excuse to get an UltraGauge. |

I own both SG & UG. The SG is nearly 3X as expensive, difficult to program, limited in its information display, and it looks antiquated. On the good side, it supports some functions that the UG doesn't, IF you're techno-savvy and patient enough to spend the necessary hours to program it.
The UG is plug and play. It will scan your OBD-II communications protocol & recognize your vehicle's display capabilities within a minute of plugging it in. Both will show instantaneous mpg, trip and tank average mpg, & other useful information like coolant and air intake temperatures, battery voltage, speed, and they'll both scan and clear CEL trouble codes. If I were buying another such device tomorrow, or recommending one for a new purchaser, I recommend the UG - unless it will be plugged into a Prius. The Prius community has developed a wealth of programming codes for Prius functions that only the SG supports. |

I'm willing to buy also some scan-tool. I was thinking into the direction of software for android phones, connected via bluetooth on the OBD-connector. Does nobody has experience with this kind of applications?

For the majority, the SG is hard to justify over the UG. |

The UG can cycle through three screens with six gauges on each screen, by pushing a single button three times. You can view any of 18 gauges almost instantly with the UG. The SG has only one screen, showing only four gauges. To cycle in a different gauge, you have to cycle through perhaps 20 standard preprogrammed gauges and up to 24 xgauges by repeatedly pushing the same button. Changing all four gauges requires ~100 button pushes on the SG, and a proportionately longer set-up time. |
Re: Monitoring Devices
realize that the scangauge came out several years before the ultra gauge. the people that did the scangauge had to do it all themselves where as the ultragauge people had a lot to build from. R+D is expensive. you also have the added feature of removing the cord from the scangauge so you can go from car to car and not have to have the wire dangling around when you do install it.
I can say that the ultragauge is a nice setup, it still has its disadvantages. I think it is a personal preference whether they outweigh the price difference as I am very partial to the scangauge. two guys that I work with have ultragauges so I have played with them. for a long time, scangauge was pretty much the only way to go for OBD-II (not because it was the best, but because there was nothing else) |
Re: Monitoring Devices
Sorry for the rebirth.
I have a obd2 Del sol but am going to be putting a obd1 ecu in it. Will it still be able to read the ecu though the obd2 port or will the signal get lost? |
