04yellowS,

What engine map are you running? Are you using MTH's software? How much does it cost to have the DSC mod done, is it the same price as the engine map itself? Can I specify MTH to remove my RPM hang as well but not change the engine map? Thanks!

John

 

Actually, from what I've been able to gather, 14.6:1 is the "ideal stochiometric" ratio. Also, like torque curves, a/f curves should be as flat as possible. My ham-fisted attempts at tuning my motorcycle have resulted in similarly lumpy a/f curves (and torque curves, for that matter...). Vader's a/f curve indicates that the engine's running very rich.

I found an interesting article that discusses some of the issues surrounding air/fuel mixtures on the dyno.

 

When I try to open Cartunes I see this. I have xp on my computer. Any ideas?



update: Problem solved. I had to clean the temp file on my computer to fix the problem.

 

guys is the MTH worth the while on a stock MCS??

im getting abit annoyed with the DSC bogging the car everytime im driving.

 

In an old thread about MTH a dyno graph showed a gain of about 10hp and 9lb of tourque on a bone stock MCS. Also better pedal response.
Also you can tell Franz that you might be running on 93 octane rather then the reccomended 91 and see slightly better gas mileage.:smile:
I think its worth it.

 

14.6:1 is stoichiometric, but very dangerous as temperatures increase [prone to [pre]detonation]. All stoichiometric means is that that is the precise amount of gas to air needed to have combustion. Engines run rich by adding more fuel to a) ensure you never run too lean to combust and b) to keep temps down. The fact that his stock MCS was running that kind of A/F means either that the A/F wasn't being calculated or that it was running scary lean. Most tuners try to keep A/F's around 12.5 to be safe. Some people will tune higher using AFC's, but, again, with intake temps being high on our cars, that can well blow something.

 

Is this the case with the standard MTH software or the new tuner software (or both?) .

Iam running on 98Octane fuel if that helps.

 

MTH does lessen the onset of DSC... why don't you just turn it off?

i didnt pay for dsc only to turn it off

i have a small piece of comfort knowing that its turned on and knowing what DSC does - the ONLY thing i dont like is the sensitivity.. so if this software can help im thinking of getting that.


cheers.

 

DSC is great to have, but I find myself turning it off whenever I start from a stand still. I wish it were programmed to kick in after a preset speed. DSC activating when pulling into traffic is the pits--no power, and on coming traffic barreling down on you.

As soon as I'm moving quickly, like on the freeway, DSC comes back on. Its especially annoying when your tires start to wear down and are less sticky--thus triggering DSC even more.

The MTH ECU mod has no effect on DSC other than offering an improvement to its functionality for MC owners.

Since the MINI isn't smart enough to know when to turn it on and off, it's really not bad advice as there are times when you definitely don't want DSC to trigger.

This is based on the standard MTH software. I have not seen any dyno graphs of the newer more expensive MTH maps.

 

excellent. thanks everyone for the input. i think i might just get the mth once i fit the cai , exhaust and pulley rather than now.. hopefully by then ill be able to read up on some input on the new mth software..

thanks again folks

 

As others said, it's just too darn sensitive. I don't want to have to remember to do anything other than drive the car. If I turn DSC off to pull out into traffic, there's a good chance I'll forget to turn it back on and won't have it when I need it.

I can also feel it when I'm trying to go fast and accelerate through an intersection (usually faster than I should be), and that's fine. I'm just looking to keep it from "helping" me when I chirp the tires trying to get up to speed with traffic out of a drive way. I'd almost go so far as to call DSC "unsafe" in its current configuration...

 

The fact that the traction control is turned down to (what should be) normal, is what swung me to MTH in the first place, from my local GIAC guy. I am VERY glad I did.

 

has anyone tried out the new ' tuners software' - is it worth the extra cost?

 

Your standard upgrade mainly removes stumble and many other niggles with standard software.

The TUNER FILES really do give better power and increased toque especially low down in the rev range on Cooper and Cooper S models (not forgetting WORKS too )

And if you use there own exhaust manifolds due out soon on there shop you can get an approx extra 10bhp on top of the tuner bhp figure

 

I ran the standard for a few months and upgraded to 'tuner' when it came out - VERY worth it!!

 

Dont know about here on NAM but MTH are official sponsors on MINI2,
cant wait for their new shop to open,
they are hopefull it will be open by the end of the month,

 

Kaelaria,

I can't remember if you are running a reduc pulley or not. If not, if you use the tuner version and add a pulley will MTH send another file if you request it like the standard MTH?

Thanks.

 

Yes, I only run a 15%, jcw intake, denso colder plugs (not needed but they are already in) and specified 93 minimum octane. Yes they stated that with the tuner file you get 12 months of free updates.

 

Cool, thanks for the info.

 

I recently decided to go with Franz's MTH PowerChip. Perhaps I'm missing something, but the way I understood it from the threads here, you order the OBD interface & cable, purchase the CarTune software & register with MTH (end of expenses). You then send Franz your existing ECU map, he does his magic & you upload that... and he'll do future maps at no further cost. While I am still waiting for my OBD interface & cable, I did get an email from Volker Kurch @ MTH breaking down what is available, map-wise. Standard file @ 150 Euro & Tuner file @ 300 Euro! Is that right, or something new? I thought I was done with my credit card for the time being. Either way, I'm already in for $188.18 US, so I'll stick with the MTH route. I was just hoping someone might clarify this for me. Also, I have not inquired to Volker on this.

 

They've changed their business model somewhat. Basically they were being swamped with update requests daily and couldn't keep the free updates as initially stated.

If you write to Volker (his English is better than Franz's) he can give you the specifics. I don't want to get into too much explanation because I don't want to sound like I'm trying to sell their products here. But since they've become a M2 sponsor, maybe they'll revisit the possibility of becoming sponsors here too.

 

Great. Thanks CoryB. Everyone speaks quite highly of MTH, so I have no reservations about going with them. The free remaps did sound like it could easily get out of hand;-)

 

Read back a few pages in this thread, it's been covered.
