The tuner choice.

[LAT]

I chose to go with MTM although it was not the least expensive. At full price of $4,900 it is only 3% premium on the price we paid for our cars for almost 8 % in power. How is that for justification.....l

The why?
1, no breach of seal on ECU mounts, difficult access avoided, worries about shipping electronics, especially overseas.
2. maintain original file for swap back, keep on a memory stick,
3. no down time, more important to those of us in the North,
4. solid reputation of MTM,
5. solid reputation of Hoppen,
6. Free upgrade to new software if Audi upgrades software,
7. Easy to restore settings if dealer over rides flash, plug and play,
8. The best reason of all. It works, proof on my dyno sheets and with my recent experience.

The deal?
I was able to make a deal with Michael at Hoppen that I would buy the software on the condition that if it didn't work I would get a full refund and a reset to stock. I was to pay for and chose the dyno shop I would work with. I was more concerned with performance than finding the lowest price flash on the market. I did get a discount to help offset the dyno shop cost.

The how?
I was able to arrange for before and after dyno runs on a Dyno Dynamics 4 wheel dyno at Chicago Performance Tuning. We, Al Ushinski, the owner and I did a set of before and a set of after that you can see attached. A quick plug for Al who was willing to tie up his dyno for this exercise, first class operator and operation. During this exercise the car remained strapped to the dyno as did all sensors so as to minimize any variables. Power numbers are not extrapolated but the actual AWD HP that was achieved. The first pre flash run was at 12:11 pm., the first post flash run was made at 3:13 pm, we did 3 before and 3 after runs. It took the best part of 3 hours to upload and download the program files. All the uploading and downloading was done by Hoppen Motorsports by Internet and went seamlessly.

The car
The car was stock and had 4,5K miles on it at time of testing and it is a 6 spd manual.

The result
Before flash 378.2 HP @ 7223 rpm and 299.2 LB FT @ 6291 rpm
After flash 407.6 HP @ 7456 rpm and 306.2 LB FT @ 6369 rpm

Straight gain of 29.4 HP or 7.7% horsepower and 7.0 LB FT or 2.3% torque at the wheels. As seen on the graph the torque power curve is very flat with maximum torque from 3,800 rpm to 7,200 rpm.

Some facts.
There is not a lot of torque to gain. I find this fact consistent with the Lamborghini engines, even LP570-4 only claims 398 LB-FT of torque. A gain of 7 LB-FT of torque over our stock engines although it has 45 HP more

If I were to extrapolate I would use straight percentages, which would result in 566 HP and 400 LB-FT, numbers equal to a solid Lambo engine. Having done this I must admit that I don't have the expertise to verify my approach to this exercise.

What next?
To find an exhaust system and untap the rest of what maybe available. I am guessing another 15 HP.

Very nice, and congratulations on a successful outcome. I really appreciate the effort you made to get hard facts, and for sharing them with the forum.

Hmmm, very interesting. Tossing up between Stasis and MTM ECU Flash.
Does MTM flash via OBD Port? Do they have dealers in Australia?

That sounds like a low reading dyno. Here is a dyno of a stock V10 posted here awhile ago. 418 HP and 325 LB FT. Guess it shows the main point of dyno is to see gains after mods.

Yes the flash is via the OBD Port. Good luck with your decision and keep us in the loop.

Looks like a Mustang Dyno sheet,Mustangs read a little higher than DD or Maha. Maha is considered the benchmark, unfortunately there is only one in the US in Phoenix.

I've attached a link to a Maha run for a Supersprint exhaust which shows a 370.6 PS baseline run and 381.4 PS modified run. All numbers uncorrected.

You are right, it is all about the before and after numbers to verify mods.

Thanks & kudos for taking the time and making the effort to get some objective data on the costs and benefits of the upgrade, as well as posting and sharing the information. It's rare (and unfortunate) that so few take the time to gather "before" data.

Cheers

MTM has two MAHA dynos. they quote 588 hp with ECU alone. i'd like to see some real life performance numbers for one of their cars.

Have put my car on dyno twice and posted here, Once before APR tune and after and the APR did show some decent gains. Wish I had also did one when car was new before I put on Stasis Exhaust and Evo Filter kit. My last dyno was 350 whp and 280 wtq which seemed pretty good. Car is in shop right now having Stasis/VF Supercharger put on and I plan on hitting dyno next week, Should be interesting

We must keep in mind DIN numbers are 1.39% higher due to testing methods so 588 DIN is 580 SAE. I was informed that MTM had their exhaust on the car as well to achieve these numbers. Otherwise it is a lot from a ECU tune don't you agree. Even for a Lambo 560-4, a gain of 28 DIN is a lot from an ECU tune of a non detuned engine.

Sounds like it will be car to be reckoned with. Can you repost the APR tune here and whether or not the car was on and off the dyno and if it was done on the same day or not etc.,

The more of us sharing information the better this forum gets...
