Here is a comparison of my wifes '04 MCS with the MTH software with about 300 miles drivetime, VS. the BEST run it made stock. The car has no other engine performace modifications.

I can't get it to give access... here is a link to Metroplex mini forums where it is already posted:

Pretty darn good for $75.

the link didnt work for me

 

Man you are fast! Try it now i just edited it..

ok that didn't work let me try something else..

Now its working!

 

Franz is the MAN!

He is slowly but surely spelling an end to overpriced vendor marked-up ECU prices

Wait, im confused? This is a stock ECU Flash for that much?

 

its a comparison between the stock ecu as it came from the factory VS. the programming changes Franz at MTH offers.


Todd

 

Did you happen to have the raw, uncorrected figures for both days too? Were you spraying the intercooler with water during both runs?

 

I have the run files at the shop on the dyno P.C. I'll try to remember to get them. IIRC the 160.9 run was watered only at the beginning, that was the best it ever did though with the stock software. the worst run with the Mth was a 165Hp run but i didn't rev it all the way to redline because i wasn't paying attention and it took a dip at about 6K , looked like it was pulling a bit of timing. I don't think my wife was spraying water all the way through that one, being her first time.. All the others were between 168 and 170 and one at 174 but that was my fault as well, I hit the clutch right at the end before I hit the stop button, and it spiked about 4 Hp.Todd

 

Since you have a dyno and the ability to swap back and forth between stock and chipped programs, it would be interesting to see a back to back to back comparison like this:

Actually i don't. A local guy, Simon Dove loaded it up for me. I might impose upon him again some day and try for a back to back test resetting the ECU between flashes. I figure I had enough baseline information to make a fair comparison.

 

Here is a link to all the runfiles for your viewing pleasure.

hopefully it will work

The impressive part. is the 160-170 at the wheels in stock trim. no pulley etc.

 

About 160ish stock and 170ish with the MTH software. A 15% pulley will be on by the end of saturday if all goes well.

Todd

 

160 at the wheels, stock? How? The car's stock flywheel rating is only slightly more than that. I thought stock whp was between 130 and 145...

 

yes stock is at 144-145 range at the wheels

 

Maybe, he means at the crank. I remember M7 posting that it made about 9 bhp so that sounds about right.

 

Nope the 160hp was measured at the Wheels on a Dynojet 248c using the Standard correction factor. We have run several close to stock minis on our dyno and none have ever been as low as 144-145 Hp. I was under the impression that Mini intentionally underrated the motors for whatever reason.

Todd

 

interesting...haven't read that anywhere else. Guess you have some strong cars in your town.

 

I have seen a few plots of MCS's making almost the same power in stock configuration. Also I typically spray water (a mist not a garden hose) on the I/c to keep the IAT at a reasonable level to fight off knock retard. This will increase the #'s a bit as well as the correction factor we typically use adds a bit more. I don't think ANY of the correction factors that dynojet uses are particularly suited to a Forced induction car but the STD factor seems to be closest. I'm not trying to say i have the most powerful stock mini on the planet or anything just that the MTH made a measurable increase in power on my wifes car. period.

 

I made the comment about strong cars because a few people have reported 140-145 dyno'd at the wheels on a stock S, and I recorded an episode of sports car revolution where they dyno'd a cooper s with ecu, cai, and pulley upgrades and it dyno'd at 175 hp. I am not sure if it had an exhaust or not. I have the MTH and the car pulls much stronger then stock but I didn't have it dyno'd yet so I don't know how much whp it has.

On the other hand, the newest M/T road test on the 05 MCS has it doing 0-60 at 6.8 and 14.8@95 mph in the quarter mile so the newer cars might be much stronger then they are letting people know.

 

The stock number being that high is why i stated impressive. On a local Dynojet so far we have tested 3 MCS with 15% pullies and the MTH programming. no cooling on the IC except a fan. All three pulled 178 hp at the wheels which is equal to about 200 at the crank. using the 12% drivetrain loss. Also did a JCW that was retro fitted with the 210 upgrade kit. it pulled 188 hp equaling to 210 hp at the crank.


The important part about these results done by ATSTODD isnt the numbers themselves in comparing car vs car. (different dyno's can give different reading of the same car) But the gain which is important since it was done on the same dyno in approx same conditions.

If i may ask Todd are you getting A/F readings when your doing the pulls. if so i would like to see them for the stock run and after you switch to the 15% pulley. We are going to be getting intouch with Franz on our finding to see if he can fine tune the setting for our area. So i would like to see the comparison

Thanks a bunch

 

1 - The evaporation of water on the intercooler can make a very big difference on the dyno and since no other MINI dyno techs do this, these numbers aren't comparable at all to anyone else's dyno. Also mods that great more heat (pulleys, ECU programming to run leaner) are going to benefit greater from the extra cooling than a car in stock form. So that will throw off your readings of how much power a mod made. Same car and same dyno yet b/c of the cooling factor, the mod may show more power than it really makes.

2- There is no SAE correction factor for forced induction so different dynos using different correction factors also make comparisons impossible.

Even so, most dynos still show a stock MCS in the 140-145 whp range.

Don't forget the 05's are geared shorter in addition to a little more hp and are supposed to be several tenths quicker to 60. I don't think they're underestimating the power these cars make at all. Those figures sound right. :smile:

 

I checked a similarly configured car on C&D and it pulled 92 mph in the traps so it seems that the 05 changes did bump up the mph. I look at trap speed more then anything to determine hp.:smile:

 

Nine to ten Hp improvment seems to be the norm for the MTH software. Not bad for $ 75 If I had one of the $ 750 upgrades would I be seeing 90 to 100 hp gains ? Just kidding but you get the point .

Amen to that " overpriced vendor marked-up ECU prices "

Perfect example of "where's the meat!"

I'll bet there has been more than one Vendor that has tried to get a sole distributorship deal on Franz's MTH software.
