I've learned to read, supreme CFG , and found the few Race mode comments. Lesson learned to avoid scrolling through the mud via mobile. I look forward to learning from your old, dusty farts.

Well, this thread has grown as cold as the heart of darkness....

I have spent about 400 miles with the product so far. And to say it doesn't make a difference is ridiculous. Is the difference from Sport + to Race almost unintelligible? Sure. But there is a difference. I've driven the car in normal conditions with the device set to stock and race, in C, Sport +, and my I setting which is Sport + with the eco A/C (Makes a nice difference, trust me) and the RACE setting on the DINAN is fantastic in all three. I've also driven the car to the limit with all three settings in RACE and it is a big difference. The power under the pedal is much more immediate, and the delivery is fantastic. I'm almost wondering if the people complaining got the wrong install point?

No, it doesn't change top speed. We already knew that. But getting to it takes MUCH less time, and for the $270 I paid for it? Well worth it to me. An intake can't make this much power, and would cost much more.

Uh, so, you agree? Subjectively, it is mild.

It's tough to get in there for photos.

Last photo on the right shows the grey Dinan connector at the female Mercedes sensor fitting.

Unless you can show I misapplied the fitting, I'm sticking with mild as a subjective term. I'd love to be proven wrong with objective data from several other installations.

Mr. J

Subjective impressions are exactly that...subjective.

When weight is constant It's difficult to notice any hp/tq gains unless they are crazy high. There is also the placebo effect and the skeptic effect which are likely to have a greater impact on an individual's impression than anything else.

What we need are a few posted dyno runs in the stock setting and the (Dinan) S+ for the same vehicle driving modes. That's the only useful quantitative data to be gathered.

This is my connection too, and sorry the only notice mild improve is on C, and please don't ask me i only used dinan race mode and yes we here in florida have 93 Avery were.

removedCFGaccount

All the free range flapping and hissing aside, why do you think I've been so careful to use to use that term?

I have no objective data, so I must rely on almost fifty years of owning high performance cars like Jaguar, BMW, Mercedes and Lotus, often highly modified by specialty shops. I still remember my E type and the drastic change from two SU downdrafts to triple webers, albeit subjective.

FLAP AND HISS all you want but for someone with vast experience and no objective data, it is mild. Simply, based on years' of experience, the RELATIVE increase is mild.

removedCFGaccount

Well, constant doubters aside, I guess we managed to find the right one.

Oh, yeah, it is still mild, Subjectively....

Now, Dinan, you've proven the concept, so move on to another, higher level. Butt dynos are standing by...flap, hiss....

Darrington

You got a loose zip tie...probably losing 10hp!

Seriously, thanks for posting the pics.

removedCFGaccount

Seriously, the instructions make a big point of keeping them loose to avoid mechanical working.

At the end of the day, all the express and implied insults don't change the performance: assuming, hypothetically and objectively, one gets 30-40 horsepower at some throttle settings, it sho don't feel like it, subjectively.

Flap, hiss....

Returning to the general design specification, a tune for the masses, subjectively, I opine the spec was met.

Darrington

I could understand if it was different dyno runs at different times, but if these were back to back runs, I would think the delta increase is legit.

On a side note, 310hp at the wheels seems high as a baseline if our cars are 329 at the crank. Not much of a parasitic loss through the drivetrain, especially if a 4matic...?

Still would like to see Dinan weigh in on this thread...

removedCFGaccount

My little ole point is this: I assume the data provided are accurate and the published specifications for hp and torque are met, but so what, it feels mild. Nothing changes that perception for ME. If I had data showing it added 100 hp I'd still say it FEELS mild to me.

Mr. J

Not sure what got your panties in a bunch. I have not disagreed with the assessment that the gains are mild. Quite the contrary, I affirmed that sentiment in my brief write up in this thread. This is based entirely off of my own observations after installing and running the piggyback.

It seems you are unable to agree to agree and are just looking for drama. Sorry, but I'm not interested in a pissing match.

I could care less about your argument from authority. We've all met plenty of folks who have been doing things the hard way for decades while never learning anything from the experience.

I am biased towards the quantitative, that was trained into me years ago. Yes the piggy "feels mild". I agree with this now and and wrote the same previously.

Dinan claims gains up to 40hp with the piggy. I believe that this kind of gain is definitely in the "mild" camp. But again that opinion is entirely subjective and impossible to quantify. But the only way to confirm and validate this if with independant dyno testing. Nobody's *** is going to be able to quantify 2# of boost pressure or 28 vs 41hp.

So I'm curious to see the validation, but I have zero reason at this point to believe a well respected company like Dinan has inflated their claims for this unit. I strongly suspect that once we get Dyno results we are going to see gains that align closely with the marketing claims.

removedCFGaccount

Ha,ha!

No one has stated or implied anything is inflated but you.

Yes, I've been doing things the "hard" way....

Car, after car, after car, after car....

Let me summarize this three hundred post thread. I don't have a dog in this hunt.

-The DinanTronics unit for the C450/43 provides a modest increase in performance at a modest price.

-It is more discernible at some Agility settings more than others.

-The associated IOS smartphone app is rudimentary and buggy. The Android app is better developed.

As you were...

RTC450

I really dont care about the app and i dont pay the $300 for the app , my interest here is the 4lbs-40whp that are missing , i just will be very happy if at least i would have the improve feeling that i have in C on sport+

Mike5215

So knowing what you know now, would you recommend it as a low-cost, bang for the buck mod?

RTC450

HELL NOOOOOOOOOOOOOO!!!!!!!
I almost buy the Burgertuining JB stage 1, $ 100 bucks more and Dinan comes and give a try very very bad decision i know i will be very happy with JB im used in my BMWS for years and this guy know to make power ...

Mike5215

That's really the point, and the unfortunate result of being brave enough to go first. At least other members considering it now have some real-world info. So you feel it in Sport + but you'd prefer to be able to add the same incremental performance increase in Comfort and it's just not there? Does Sport alone split the difference?

RTC450

1- On Eco never try
2- On C you can feel mild improve
3- On S never try( you ask and i will try today)
4- On S+ almost imperceptible

Mike5215

I was just thinking if you added a MidCity Auto-Stop ($174) you could just set the car to default to Sport mode at every start-up (or build an Individual mode).

Yes, we pioneers must expect an Indian behind a rock, on occasion.

I'd suggest sitting quietly on the porch....

Mike5215

Depends on the porch I guess.

Seems like the bang for the buck ratio is dead even on this thing. Not too expensive or invasive, not a huge difference maker either.
