I would appreciate anybody's advice. I drive a Cooper 05 and recently I did the MTH modification. It definetly performed better. Lately a used Lucas Octane booster and I noticed further improvement. It sounds (?) better, better acceleration, better throtle response. I would like to keep on using it but I don't know if there are reasons why I shouldn't. What I read about it so far is somewhat confusing.

 

I'm in Austin and I have a USB cable for the MTH software upgrade, but I'm a Mac guy and from reading this thread and the older how to I'm concerned about going for it on my own. Anyone here in town want to trade the use of the cable for some help with the upgrade?

 

I too am a Mac guy... but I was able to get it working on a PC (with the USB cable) first time... with no problems. So it's not as hard as reading about it here may seem. Plus people here are very willing help walk you through it. I hope you find this helpful.

 

When trying to ID my '03 MCS, CarTune returned a message "Car electronics 000000 is unknown!".
I mailed this message to Franz and he replied that most probably the OBD interface is not working and that I have to return it to Sascha for a replacement.
I read in this thread that X-rays can damage the device, is DHL Xraying ?
Anyone had this error experience?
And did anyone need to return the OBD interface?

 

and noticed the same thing. More pop for sure. That means he's tuning the cars to let the knock sensor set timing.... Otherwise, increased octaine wouldn't do anything......

1) Has there been any MTH updates since early May? If so what was updated?

2) I got my first SES light last week but a few hours later the light turned off. What also happened was the DSC light turned on and my MCS went into some sort of limp mode. It wouldn't go over 80MPH or 3.5K RPMs. I pulled over and killed the engine. After starting her up again the SES light was still on but the DSC light was off and everything ran fine. Anyone ever experience this?

 

answer 1, well i sent my files for retuning to franz about a week and a half ago and no answer... so i dont know whats up

answer 2, that happened to me when i install the header... i took it to the dealer they reseted my computer and it was back to normal... they didnt tell me what sensor it was but there is one that when it goes SES and DSC lights go on... nothing serious b/c they didnt make a big deal out of it at the dealer...

.... i would take it to the dealer and have them reset the computer or reflash it.
remember to run MTH again after just in case... hope this helps.

 

1) - Only if you installed the larger injectors and have a 19" pulley, he has a new 'Race Program' option.

 

oh... i have the 19% but i havent gotten the larger injectors...
do you know anything else about the race map?

thanks

 

It's more agressive timing, supposedly another 10HP, but needs the higher flowing injectors.

 

If you have a modified fuel cut off, and hit it or go beyond, you will get the "limp home" response. Happened to me and scared me silly!

Also, you can reset you computer yourself. I don't remember where the instructions are (probably even in this thread), but it's easy. You can get a bunch of other information from the ECU as well.....

Matt

 

You can easily reset the adaptive ECU memory through the odometer reset button.

But to clear an error code & SES light, you'll need a scan tool. If the error was a one-time thing, the light will go out after x number of starts (I've heard anywhere from 3 to 50) but the code will remain stored in the ECU until cleared with a scan tool.

FWIW, most Autozone, Advance Auto, Kragen, etc have scan tools and will generally read/clear errors for you for free.

 

When using any OBD-II software, it utilizes the COM-Port of the computer. This is because it is performing its timing using the old TX/RX/RTS/CTS protocool, where TX=Transmit, RX=Receive, RTS="Request-To-Send". and CTS="Clear-To-Send".

When you purchase the MONO-USB, you have to run a "Virtual COM Port" driver. This driver is available on the same page that describes the MONO-USB at the bottom of the page. Click on the word "here".

I may not know much about auto mechanics, but when it comes to computers, I've been doing this for close to 30-years, now.

 

I have a question about the capabilities of the MTH software. Can it be used to adjust the electronic throttle? On my MINI, it seems that the electronic throttle control is not linear. It will accelerate at, say, 50% throttle with only 30% throttle input. This makes it more difficult to drive smoothly - especially on the track. Do you think that the MTH can change this?

Thanks!

I am in the same boat with you, Franz maybe on vaction or something. Luck of the draw, when he is there he turns the files around fast. I am sure he will get back to us when he can.

I got the JCW injectors and they're just WAITING to go on the car. Just waiting for a map back from Franz!!! And I HATE waiting...

Hay all, on another thread, someone reported sending Franz and dyno run with A/Fs and getting his tune further optimized. Anyone else do that? If I add a wideband and logging, I could potentiallly get a really good tune custom for my car......

Matt

 

I'd like info on further tuning via a/f mixture data as well...it could definitely use it!

Have any of you used the Ross-Tech OBD-II/Serial cable (HEX-COM+CAN Intelligent Interface) in conjunction with the MTH CarTune software?

It seems like it should work, but I wasn't sure.

Anybody?

 

OBDII just isn't fast enough for any serious logging. CAN might be fast enough....

Matt

 

Franz was once again sent a virus by somebody here in the states..

If you have not heard from him.. I would suggest re-submitting..

 

I'm not sure of what your point is, here. My question was merely that there is a guy in my office who purchased VAG-COM for his VW TDI and he has a cable that came with his purchase that has an OBD-II connector on one end and a DB-9 connector on the other. I just wanted to know if I could use his cable with that cable?

 

I'm not exactly sure how Franz is getting into the ECU. Some are running basically straight of the serial port at high speed. But OBDII is really slow serial... That said, I think the only chance to find out is to try....

Matt

 

Anyone know this?

 

I get him to do a change where the RPMs drop faster when you take your foot off the gas, so he has to be able to get into it somehow.... Ask.
