I'm sorry to say all of this was coverd in the deleted thread. It's sad that we all were punished for the spat between MTH and NAM. Anyway...

I had no problem uploading the original file before my v39 ECU upgrade.

Sometimes the messages get "lost" happend to one of the four I did. I've had several maps done.

He can support rev limiter changes, but be careful here. When I had the modded rev limit and I hit it, the car went into "limp home" mode. Turned off and on and on my way, but this would suck at the track. I don't know if it;s still this way or not.

The DSC mods are worth the money alone. Keep your foot down, and accereate away. I've only had it rev to high with a really wet street in a turn, and I have no limited slip.

He said he could program support for a wide band 02, but I didn't persue that. It would be the best, as the narrow bands don't have as much range as would be nice.

I asked for a list of available mods, and got no response. He seems to do better with specific question.

Sometimes the response is near instant, sometimes not. I reccomend a perscription of chill pills, but if your anxiety is high, go ahead and re-submit, but let him know that it's a re-submission, just to be polite.

Yeah, it's a bit flakey, but for the price, it's a steal.....

It is a shame that your original issues were not kept as it gives insight to newbies that life will go on here folks. Your car WILL RUN regardless of what version of MTH you have since the last upload, thus my earlier comments that I am not in a hurry to receive updates within mintues.

I haven't posted my dyno runs for MTH because I have only done one and it wasn't what you would expect. I prefer to wait for weather to stabilise in Houston before I can figure out why my readings are what thay are. I have never sent Franz a dyno chart, but I am going to email him a request to review them so I can get a upgrade that is not so rich.

Just be paitent and you will get your upgrades, it's worth the money, as I am getting 2 mpg more on this daily driver.

 

I put the MTH code in a few months ago, on top of a v39 factory flash. My 2002 MCS has Alta Inake and 15% pulley. It worked great for me. The seat-of-the-pants dyno sez that the engine/intake/pulley/MTH combo is in the 190-200 HP range, and it feels as lively as a JCW.

The only post-MTH glitch I have encountered is that I get Service Engine Soon (SES) P0128 errors occasionally. P0128 relates to engine temperature. I use a Davis CarChip E/X data logger as a routine thing, and it shows that the P0128 error occurs with the engine fully warmed up (steady 190 deg F temp) for at least 10 minutes.

Fortunately, the Davis CarChip lets me reset the SES light easily.

I wonder if anyone else is experiencing the SES P0128 fault? Have you found a fix for it?

 

Either you just got lucky, and if you reset and it never repeats, attribute it to cosmic rays!

If it repeats, it's either the sensor, or the mods have moved the operating point of the motor outside of what the sensors are looking for. If it's from a problem, you need to fix it (thremostat that doesn't open all the way for example), if it's a natural consiquece of your changes, then you have to get creative.

You have a pully, do you have cooler running plugs? You ARE releasing more energy, so a bit more heat shouldn't be a surprise. I think M7 has a lower temp thermostat, and that may help as well.

I'm running 15%, cooler plugs, an intake and the one ball exhaust. I've never had a code for temp. After stopping at a low-ball no-name gas station, I got a lean code. But just one, and it never came back.

Matt

 

Matt -- I get the P0128 about once per week. I review the precise time that the CarChip says that the SES hit, and it is in the middle of a perfectly well behaved engine temp run, typically about 10-15 minutes after I start up. When I get home, I reset the SES with the CarChip and wait for another week for it to happen again.

From the description in Bentley, it appears that the P0128 fault is a temperature UNDERflow, indicative of a thermostat stuck open, but it's not -- in my case the temperature is under perfect control at 190 +/- 2 deg F every time the SES happens.

The CarChips are nice in giving you a permanent, time-tagged history of what's happening. I log speed, RPM, coolant temp, intake temp and engine load every 5 seconds. It also flags high accel & decel incidents. Big Brother IS watching you!.

I'm running the stock (190 deg F) thermostat and stock plugs. The only other clue is that all the events have occurred since winter set in, typically with outside temps in the teens or twenties. It will be interesting to see what happens now that spring is setting in with temps in the 40s & 50s.

Thanks for the tips -- it will be interesting to see who else reports MTH P0128 events -- Tom

 

Having SES codes on a "regular basis" seems "worrisome" based on the posts above. That would worry me? Anyone try asking JLM or Randy webb or Eric from Helix13 about what to do with all these codes?

On the one hand the codes can be cleared. On the other (will) they recur with regularity. If you have codes that are not attended to and you keep adding more mods what do you think might happen?

Maybe more and more SES codes. Maybe now they won't clear. Seems troublesome and potentially dangerous if the engine is operating outside of normal specifications- hence the SES codes.

Anytime I've had SES codes I've had them checked out and fixed. Be careful out there. Be sure to report problems so others will know.

 

I just spent time looking on the web, and I found

https://www.northamericanmotoring.co...ad.php?t=39220

But if the temps are good, it's a bit of a mystery. Are there other temps to log? When I looked at the logger you use, it only gives four values besides the vehicle speed etc. stuff. But other than looking at other variables, I have no clue how the flag for that error is set.

Maybe one of the experts here knows how that's tripped.....

FYI -- the complete list of universal OBD2 codes is available at this site.

The P0128 error (also quoted by Bentley for the MINI) reads
P0128 - Coolant Thermostat Below Thermostat Regulating Temperature (i.e. a temperature UNDERflow) -- Tom

 

I got my tuned file just now after 9 days. But it does not work. It gives me "Incorrect keycode !!!" error when I load it with my keycode entered in the blue area. I've emailed Franz. Hopefully he won't take 9 days to respond this time.

 

Actually, as an extremely satisfied MTH JCW 210 owner, this wouldn't suprise me at all. I have not done a dyno with MTH either but I have developed a few opinions (right or wrong) about the net effect of the MTH maps...so here goes:

1) MTH maps seem to make the car more driveable.

They address the predictable preformance compromises to engine tuning inherent in MINI's need to achieve (close to) advertised efficiency and HP/torque specs across a variety of fuel grades and blends. To tune the maps for a specific grade/blend of fuel will, potentially, allow the extraction of the greatest level of performance from the stock setup.

However, there is a limit to what can be extracted from the stock engine and the gain might be expected to vary across the RPM band. If the increased performance is not at its highest at peak torque or Peak HP, the raw dyno numbers may not show much change. I might expect that the torque and HP traces across the RPM range on the dyno might be somewhat different, even if the peak values are not.

I have felt a smoother delivery of power with the MTH maps. It actually felt quite different from the stock JCW software in that the torque seems to build a bit earlier and develop in a more linear fashion. Of course after 4500, the thing goes into hyperspace so it is hard to pinpoint any subtle differences beyond that point.

I might also make mention that my MCS was delivered with the dreaded "Yo-Yo". I have had MINI ECU V.38 and V.39.x installed and they lessened the yo-yo but did not eliminate it. The Ryephix2 bypass valve spring helped things out quite nicely, but I have removed the spring since the JCW 210 and MTH. There is not even the slightest hint of a yo-yo now.

One word of caution, however. The yo-yo is a very elusive problem that cannot be completely addressed by ECU versions since its origin is in other software used by a sensor to "speak" with a controller; A/F maps will only have a limited bearing on this issue. I do not know what specific combination of changes have masked my yo-yo and fully expect that its ghost will revisit me at some time in the future. Thus, I DO NOT want to leave the impression that the MTH maps cured my yo-yo. I'm not exactly sure what or what combination of things did.

2) The threshhold modifications to the ASC system seem to allow power/torque to build earlier in the RPM band.

Those with a keen feel for the MCS know that it seems a little balky off the line. If you have experimented with launching your car with ASC/DSC turned off, you know the improvements that can be found by doing that. However, this will deactivate the system so any subsequent benefit that ASC/DSC would lend to car control cannot be realized unless you remember to turn it back on.

By increasing the limits of allowable wheel spin, MTH is making the system a little less agressive. In my opinion, and as experienced in my driving, MTH have reached a very nice compromise between the factory limits and performance oriented limits. It would not suprise me to find the torque and HP traces beginning and building earlier in the RPM with the MTH maps as opposed to stock maps.

A work of caution, however. Most of us are experienced, performance-oriented drivers with a very good "feel" for car-handling dynamics and are sensitive to the continual feedback given to us (on purpose) by the MINI. A new or lesser experienced MINI driver (?) might not experience that subtle driver/car connection we have developed. And, while we may be able to "feel" the gradual approach toward the limits of the MINI's handling/traction capabilities, a new driver may not. Thus, you should think about who will be driving your MINI before you ask Franz to modify the ASC limits.

So, to sum thing up...

I would not be suprised to see dyno numbers that do not reflect a dramatic difference from stock. IMHO, it is the driveability of the MINI that is the area of impact for the MTH maps.

However, I would expect to see a difference in the traces for torque and HP. The torque and HP traces might begin a little earlier and build a little sooner but, ultimately, be close to the stock peak value at approximately the same RPM value.

Lastly, one of the nice things about the MTH software is the ability to "catalog" different ECU maps and to load and unload them at will. Thus it makes before and after dyno comparisons possible.

FWIW,

Theo

 

I'm confused on the cable. I can't locate a product on the Sensolutions site - can someone post a link to the exact product needed?

Is this the correct product, but from Germany? http://www.obd-interface.de/pages/sh...m?categoryId=2

 

This is a bit off-topic, but I think it's improtant enough to speak to, since it was mentioned above.....

I'm running the ryefix2 (stiffer bypass valve spring) and just came across this thread about routing a different vacuum source to control the bypass. The thread has lots of data and details, and looks inexpensive and effective. I haven't installed it yet, but here's the link...

All the info you need is here: http://www.cooperspeed.com/forums/article.php?a=22

 

2/28, I contaced Sensolutions for info about the cable and the response was:
"We are switching over to our new web-site and obviously this in not going too smooth.

You can complete your order here:

Please note that you want a MONO-USB.

Otherwise you can give me a call:

I needed the drivers and could not figure out how to download them. Martin provided me the link:

"You can download the driver here:

http://www.sensolutions.com/testSite...SB_drivers.zip

Once installed you should see that you now have a virtual com port added to your system "panel". This is the com port you want to use with the MTH software. "

Everything ended up working fine.

Cool, thank you.

 

This Saturday I finally received my car back after being at the dealer for 3 weeks. I've had the SES light coming on for P0128 3 times since November. It seems for me that it comes on only after my car hasn't been run in approx 48-72 hours. If I drive it every day, no problems. They had previously replaced the thermostat twice, and temp sensor. Their final resolution was to load the John Cooperworks software and leave it...

 

I had this with the 3rd of 5 flashes from Franz. Number 4 or 5 haven't tripped a light... Its purely a guess, but I suspect Franz is using some artificial temp sensor values to massage timing a wee bit.

 

I continue having problems with the id of my car... I always get an error:
"echo is missing", "unable to open come port" and something about timeouts..I´m bored of traying things what can i do??

 

The issue is the MTH software can't see the ECU, because it is trying the incorrect COM port. You will need to do one of two things:
1. In MTH you can select a different COM port, ranging from COM1 - COM5. Give them a try and see which works.
2. Because the USB cable creates a dynamic COM port, it often selects a number out of the range MTH understands. In this case to go control panel - system - hardware tab - device manager. In the Ports category, find the USB to Serial listing, and go into properties. From there you can select an avialable COM port in range (less than 5).

 

FYI, this has all be clearly documented on the first post and on my tutorial linked from the first post--with pictures and text.

Ricahrd

 

octane dude did it for us. I just followed his instructions months ago and no issues in the 3 updates since.


If you get freaked out, please go to www.minimods.us and post your question directly to Franz. This site was created a week ago to support MTH related issues and Franz HIMSELF is a member and answering queries. I know cuz I posted to him and he has answered the next day.

Kevin

 

Ok i´ll check the page. I´ve already set the com port in both places, the mth software and in the hardware settings and continues not working for me..

 

Aside from the settings, be absolutely sure your computer is set up properly. That is, check under the Device Settings and make sure your COM ports are active and not turned off which is common with USB systems today. Then make sure that a COM port between 1 to 5 is available and not already assigned somewhere.

Once you are certain that the physical connections/hardware portions on the computer are working and correct, then troubleshoot the MTH software/OBDII hardware.

If everything is corrrect, you should be able to click the ID button and get a readout on your ECU through the software.

I just threw my first 0128 code this week.. seemed odd..


ambient temp was 68 degrees.. engine fully warmed up..

was doing 79mph in 4th and upshifted to 5th and the light came on..

how odd..

andy

 

Andy -- same symptoms that I reported, except we still haven't hit a 68 deg temp.

I send my files off to Fritz and described the P0128 fault. It will be interested to see if he sends back a version that cures the SES P0128 fault. -- Tom
