Re: SuperMID Up and Running
 

I would suggest maybe doing a highway trial that can be completed in an hour or two and still be tenths or hundreds of a MPG accurate. Then you could have you gauge up and running (calibrated) a lot sooner. Top off, spend some time enjoying that sexy Del Sol of yours, top off again, and calculate. I've done a few tests this way and the results are surprisingly accurate. Accurate enough to measure the effects of a few degrees of ambient temperature difference in fuel economy.

this is great news, krousdb.
 

this is great news, krousdb. an mpg computer for the non obd2 set.

the price isn't too crazy. at $160 it's $30 more than a new scangauge, but less than many of the laptop-connectable OBD scanners.

Re: SuperMID Up and Running
 

Thank you for your report.
Glad to hear the basic functions are working well.

Re: How does it work so that
 

It measures the pulse width of injector for the fuel usage.
If the vehicle goes to the fuel cut mode, the pulse width becomes zero.
Basically, the SuperMID M-1 works on any car which has fuel injectors and speed(distance) pulse output.

Do you know the pins for these signals from your ECU?

Re: SuperMID Up and Running
 

No, it does not. :)
It looks like this...
upper: SuperMID M-1 (mileage meter)
lower: SuperMID T-1 (tacho meter)

Re: SuperMID Up and Running
 

I found a convienient place to mount it. I didn't really need a case. you can't see it from the outside of the car because it is hidden by the safety and emmission stickers.

Another interesting point is the % time the engine is running and FE while the engine is running(shown as 76% and 19.46 km/l). During the 6 mile test run, the injectors were only active for 76% of the trip time, either because the engine was off completely or the injectors were cutoff during closed throttle engine braking. Whil the engine is running, my FE is shown as 19.46 km/L or 46 MPG. Now some of the off time was due to stopping at a convinience store for a few minutes to pick up some stuff. Also I had the supermid runnning for several minutes during installation so the 27 minute and 21km/h ave speed are not truly indicative of the trip.

More to come. Thanks Yoshi!

Re: this is great news, krousdb.
 

I'm guessing that shipping is ~$30. So buying in bulk should be cheaper. A kit would be even less but Yoshi says they are hard to build.

i'll also point out that
 

i'll also point out that this is more accurate than the scangauge, which apparently doesn't recognize the injectors-off condition.

USA-centric
 

I know that this is rather USA-centric of me, but it DOES display US miles and gallons, right?

Re: USA-centric
 

Not with it's current programming. I thought that I would just adjust the fuel and distance parameters to force a MPG output but unfortunately there is not enough range in those numbers to do that. I am used to km/L from having it in my Prius. Just take the the km/L output and multiply by 2.35. My target is 22 km/L which is 51.7 MPG. If you just keep that target in mind, you at least know if you are above or below it.
