I don't know what the signals look like but if the SuperMid can't accurately work with 2 pulses/rev, then couldn't you make an adapter that always doubles the number of pulses - like a dual-edge triggered one-shot that sends a pulse at both the positive going edge, and one at the negative going edge? Would that bring it into 'calibration' range? Just curious.

Yoshi : What happens if the speed sensor on the car only has 2 pulses per revolution? Can SuperMID be adjusted for this?
In that case, you'll see 1 km distance display when you drove actual 2 km and 10 km/L display for the actual 20 km/L.
SuperMID has adjustment capability, but it limits within a certain range to find out the value was not out of order caused by malfunction.
Since you're asking, do you mean your vehicle supplies 2 pulses per revolution?
My vehicle supplies 2 pulses per revolution. However, I will be remembering a conversion table from the units on the SuperMID, to UK MPG. So, it will make no real difference, and I will be able to see a 2km average distance instead of a 1km average (which will be useful for engine-off coasting around here (where you can do a few 100m up a hill, then a few hundred down).

I see. I think the software solution, modifying the program, will be the best.
Regarding to the fuel parameter, we have to adjust it to meet the actual fuel usage. We know a good number for the Prius, but I had no idea about your Bluebird. I did put a guess number to your SuperMID flying to UK.
So, I'm thinking I'll send you modified processor chip after you find out the correct fuel parameter including the distance pulse adjustment.
