Supermid Distance and Fuel Calibration Constants?

Anybody have any Supermid calibration numbers for CRX H? I just want to start with them close and calibrate over a full tank.

Hi,
I would like to comment some...
It'll take long time to find the calibration numbers within 1% error on your CRX.
Please accumulate three tanks for the fuel usage adjustment.
The distance 2572 should be dead on if you wear a standard size of tires.
Anyway, the injector size on other CRX is different(more than 2%) from yours and tire diameter is also different, therefore the other CRX's calibration data is not always fitted to yours.

Anyways I'm just going to calibrate it so 1 km/L = 2 mpg

"The distance 2572 should be dead on if you wear a standard size of tires."

My km reading is over by a factor of 1.39 so my vss signal must be off but I'll just fudge the number when I get a more accurate reading.

Thanks again Yoshi, nice product

So, you're reading 1.39km when you drive real 1km, aren't you?
Maybe, your CRX has mechanical vss.

Thank YOU!

Anyway, a relative number is still good to compare your various technique for fuel efficiency. The absolute accuracy is not so important to compare them.

If you need less than 1% accuracy, you have to do the calibration.
BTW, the 4500cc injectors are huge!
I've seen 550cc/min injectors, but...

you should PM him.



well I messed with my wiring and I guess I had a loose connection. Now the KMs seem to be on. I guess the vss wire was wiggling a little causing extra pulses

I don't bother calibrating my SuperMID As it is the improvement in the number that counts anyway.

Be sure to write the numbers down, as, on the older SuperMIDs, the calibration didn't change ALL the numbers on the main display. This has probably been updated now, but is why I just keep the standard calibration!
