Fill me in on the features of the SuperMID...the Cliff notes version is fine. I am assuming, since your car is pre-OBDII that this works with any OBDI (including my 94 XFi). Does it have the same functions/features as the Scangauge?...
Scan Gauge says...
Reads Trouble Codes
Reads conditions that set the Trouble Code
Clears Trouble Codes
Turns off "Check Engine" light
Make and store up to 10 rewritable special codes
to send to the vehicle computer
Shows 4 gauges at a time from the possible following:
Intake Air Temperature
Engine Speed (RPM)
Vehicle speed (MPH)
Manifold Pressure (not available on some vehicles)
Automatically tracks three sets of trip data -
Current (short) Trip
Days (total) Trips
Previous Days Trips
Maximum Coolant Temperature
Trip Fuel Economy
Check out the thread in the DIY section, I dunno everything off hand. However, because of the nature of obd1 stuff it can't possibly do all this, but I don't mind really because I can check codes by jumping a wire and everything else I can do on a computer.
The main thing is that this works for any EFI car (I think, yeah?), but scangauge is only good for more cars 96+ (few exceptions).
Dan has gotten his calibration done and all that. The basic idea however is just like you said, instantaneous fuel usage. You can also do trips and **** like that, which is good, but this thing will let you know immediately if a mod you did worked or not, good stuff.
Calibration is fine for reading distance and fuel used. But as I mentioned before, the instantaneous FE reading does not change with the fuel calibration as it uses a fixed value that corresponds to the Prius. So in my case, when my target is 25 km/L average, I know to target a 30 km/L instantaneous. No big deal. Just determine your targets.
Sent the International Money Order today. If anyone else wants one I will give you Yoshi's address so you can send the international MO yourself. I will then ask him to ship them together for a break on shipping.
