My 03' R53 was feeling sluggish a bit, and getting more yo-yo's starting out than usual. Made all the usual checks to no avail.
Then I went to Helix's web site last night and saw their DIY list and in particular, re-setting the ECU. I have heard of this before, but required the removing of the POS battery terminal.
Helix had the instructions for doing it with the trip counter reset button and the MINI's ignition key.
Worked the first try using their instructions, and my MINI is back to normal. Now the throttle snappiness is back, and trip computer indicates a highway mileage increase of almost 2 mpg !

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)

Just put it through the gas. It is some amazing stuff.
I've been using Seafoam or other various cleaners like that about every 5,000 miles since the car was new. I'm willing to bet it is squeaky clean inside my engine.

explain what you mean by "yo-yo's" starting up..if its what im thinking, my car is doing the same thing. i may reset my ECU today and see how it helps

Yo-Yo - Upon starting out in 1st gear, I was getting some hesitation like the by pass valve spring was weak.
It began soon after using the new Ethenol blended fuels. Didn't happen with every tank because I have to fuel up in differnent regions, but up until now it seemed to happen all the time no matter where I filled up.
Use the method outlined above, it was easy. Just follow the steps in your head first time around and then do it. It's idiot proof and it worked first time around.

Just a quick question.....If reset the ECU will it affect my maintenence counter?

Thank you very much adrianr, after reading this post I was going to go outside and reset my ECU, but I wanted to make sure that I wouldn't upset the maintenence counter....which leads me to another quick question....I am out of warranty on my MINI now, and will be doing my own maintenence now, is there anyway to reset the counter myself, when I do work? Or will it always just say that I need maintenece done?
Thanks Again,
Jodi

A couple of weeks ago, I did an oil/filter change on Emily ('02 MCS, Chili Red w/a Black hat), and put in new plugs. I reset the maintenance counter, but for some reason, while the mainenance counter reset, the average speed and mpg counter were unchanged. So I did it again, all to no avail.
Then last Sunday, before going out for breakfast (mmmm, pancakes at Easter's), I picked up some Seafoam from the local AutoZoo, gassed up, and reset the ECM following the procedure outlined above.
Voila!
Everything reset to zero.
I immediately noticed an increase in throttle sensitivity, and it felt like the response had improved.
After I performed the reset, I jumped on the highway, and did a small Italian tune-up, by running a couple of miles at ~6k RPMs.
I think she liked it....
Well i did it too last night and the car is running better .Now is it in my head
or is it actually happening .As after i wash and detail it ir runs better,install Alta cai runs better ,got rid of the run flats runs better,fixed my mushrooms added plates and stb runs better ,changed headlights runs better and i am about to change stripes and i'm sure it will run f in better.So what is the tech stuff behind this mode ?I just want to be better informed .I will get mental help for the rest .
