Could someone with the trip computer option do a test for me?

I am currently trying to test to see what kind of MPG my 03 can get, and am using the mpg readout from the odometer area when you enter the code at start up found here;

Quote:

With the key in the ignition, but in the off position, press and hold down the odometer reset button with one hand, while holding the button down, switch the key in the ignition to position 1 (first click) with the other hand. The screen will have a number and the word “tESt”. Scroll through the numbers by pressing the odometer rest button, through to 19 and wait a moment. (Note: the number order is: 1,2,10,19) The message will say 19 "L i-off", flash to "L i-on", and back to "L i-off" again. When "log i-off" appears, press the odometer rest button again. You are now in the system. Scroll through to 21. tESt and wait a moment. 21.0 rESEt will come up. Press the button once.
Your gauges will now make some sounds and movements.
Once the lights come back on start your car. You have now reset your ECU and your MINI is now ready to relearn the new mods and your driving style.

Here is a list of all the tests on your MINI:
1.0 Chassis number
1.1 Kilometer count
1.2 Parts number
1.3 Coding-, Diagnostic- and Bus-index
1.4 Production Date (Calendar week/year)
1.5 Hard- and Software status
1.6 Injector status, Cylinder count, Engine factor.
2.0 Comb system Test
3.0 Service interval counter
4.0 Actual fuel consumption in l/100km. eg.0154 = 15,4 liters/100kms.
4.1 Consumption in liters/100kms.
5.0 Distance consumption in l/100kms.
5.1 Actual rest distance with available fuel in Kms.
6.0 Actual amount of fuel in tank. eg. 123321 =12,3liters left 32,1 liters right
6.1 Total amount of fuel in tank.
6.2 Show value of Fuel gauge.
1= both senders OK, 2= sender failure, 3=ti signal implausible (no reading)
7.0 Actual coolant temp.
7.1 Actual outside temp.
7.2 Actual engine revs.
7.3 Actual speed
8.0 Hexadecimal readings of menu 7.0 to 7.3
9.0 Actual on board voltage (Battery)
10.0 Land codes
11.0 Unit codes
12.0 No function
13.0 Gong test
14.0 - 14.4 On board diagnostic codes. eg 000000 = no failures
15.0 - 18.0 No function
19.0 On/Off for Test menu.
20.0 Correction factor for Fuel consumption Formula for correction:
Shown consumption x 1000 / user defined consumption
Push the trip reset button to begin the correction. Numbers count up from 0-9, when correct number shows push trip reset button.
20.1 Sets 10ths. for consumption factor
20.2 Sets 100ths. and 1000ths. For consumption factor
20.3 saves the new consumption factor and shows new value
21.0 Software reset. (Same as disconnecting battery)

My question is that as you can see there are two different readouts for MPG using this method, both provide similar readouts, but not exactly the same.

Would anyone who has the OEM trip computer option with the MPG readout be able to go into this menu and compair the readout on the Tach to the readout on the Odometer and see if it is 4.0 or 4.1 which is the true MPG indicator?

Thanks alot!

I'm not helping you here, but unless this is a purely academic exercise, which is fine (I'm a certified, card carrying nerd-geek myself, so I know how that goes) neither is a number you should go the bank on unless you have compared it to basic gallons/miles calc. and don't use your odometer for this, you need accurate mileage.

I use the mile markers on the side of U.S. roads over a fairly long run to determine a factor for my odometer, then do the manual calcs. My MINI (O6) used to be about 1.6% optimistic on the odo, since I have changed tires, it is about 0.7% optimistic. Data that is worth nothing except for have some fun calculations.

Hope this is of some very little value to you.
