Pat (tradiuz) from MTH-USA and I are currently working on a problem I'm having with CarTune. I am attempting to read and download the data from my June 2005 build Cooper S convertible, and per the Info section at MTH-USA, it should be using the Siemens EMS 5150 ECU chip.

When I use CarTune to ID the chip, it detects the car as a "R53 T? with Siemens EMS 5150," as it probably should. However, the Start Address and Length are both zero, which leads to a "Length is 0!" error when I try to download the file. Please see the attached screenshots of CarTune for a visual idea of what I'm referring to.

So I select the "R53 with Siemens EMS 2K" option from the pull-down menu, and have no trouble obtaining a valid Start Address and Length, which allows me to download the files. I sent these to Pat, who informs me that he always allows CarTune to automatically identify the chip, since it is never inaccurate. I take all the precautions to ensure that my Sensolutions MONO-USB cable is well-seated in the OBDII connector, and that all extraneous programs/processes on my notebook running WinXP are stopped, with no progress.

This is not my first experience with MTH chiptuning - I had MTH back when Franz was tuning files for just the price of CarTune on my older Cooper, and I never encountered anything like this. I am hoping that someone with CarTune experience (perhaps Volker?) can be of assistance with this one. Is this a case of an improper identification by CarTune, and I can procced with having the files identified as from the Siemens EMS 2K tuned and uploaded? Or will that be detrimental to my Mini? Is there something that I've neglected to do that caused the improper ID? Thanks in advance!

 

the second pic looks correct.. i got that error with the with wrong com port.. try a different com port and be sure to change the com porrt on catune..

 

I tried two different USB ports, one of which gave me COM4 and another COM5, with the same results. Even restarted CarTune after I changed the COM port within the program to match that of the cable to ensure that the setting was remembered by the program. I suppose I could try adjusting the COM port manually (COM1-COM3), and see if that makes a difference. Thanks for the suggestion!

 

I tried setting the COM port to 1 and 2, both with no success.

I've also tried manually inputting the Start Address and Length as 70000 and ef10 respectively to download the file with Siemens EMS 5150 selected, and that causes the error "Car electronics not supported!" pop up.

I've also attempted what Morales suggested in Post #16 here, again with no success:

I understand that CarTune is not a MTH product, but it is integral to customers who actually want to use the MTH tune on their cars. Maybe I'm wrong, and this isn't a CarTune error. Pat still hasn't responded to me since Wednesday morning - maybe he's on holiday? I've got a dyno day coming up next Saturday, and I was looking forward to seeing how MTH will improve performance.

 

PM Sent!

 

Thanks to BMDoubleU for going completely out of his way to help!

I've got the files properly downloaded now. The trouble happened to be with the Dell that I borrowed for the download - even though I had stopped all processes that were extraneous, it refused to download the original files. The last time I did MTH, I had my trusty old ThinkPad, and never encountered a single error. Go figure.

 

no problem... (helping you gave me another reason to have fun driving my car!)..

btw, all you need now is the crank pulley, wires, and ik22 plugs and you'll have what i have.. 201hp at the wheels.. or pretty close. .. (your LSD will make all the extra power usable)

 

Thats interesting to hear about your DELL....my Dell 5150 works wonders, and ive certainly done a few MTH upgrades now using it

 

This is an interesting thread to me because all I have ever used was the R53 with Siemens EMS 2K option. I have downloaded files and uploaded files several times without a problem. Should I be using something different and does it make a difference?

 

Aslong as people use the "ID ?" button and let cartune detect automatically, then it shouldnt cause any problems at all....we have done many many MINIs with no problems at all

 

You're forgetting the Milltek cat-back, too - everything sounded great together as you pulled out of the lot.

I hope to push 180-185 whp with MTH on top of my other mods. Here's hoping I receive it by Friday for the dyno on Saturday! :impatient

 

I was using a Dell Inspiron 5100 that I borrowed from my parents - I have no idea what was installed on it or any prior glitches, but I did stop all processes that were extraneous, and still no go. BMDoubleU had to come out to troubleshoot it, and after I showed him the errors that CarTune was giving me, he successfully downloaded the original files with his Toshiba in a minute.

If only I hadn't sold my ThinkPad - my only notebook now is an Apple iBook that works great for everything but MTH. I'll just have to borrow one from work once I get the files back for uploading.

 

Glad to hear everything is sorted now. Btw, CARTUNE is a MTH product - developed by us.

 

Colour me sheepish - I thought I saw Franz's name in the credits, but I assumed that it was because MTH had the developers of CarTune make a version specific to MTH's purposes.

Thanks for your help, sir! BTW, I sent you a PM - I hope you won't mind taking a moment to respond to it.
