Had this installed a few weeks ago at my local Dinan shop. Power is much better than stock even in comfort mode.

SLOW C240

How many hp increase?

Would this work for the E400 coupe?

E400 not supported.

ELITE (DINANTRONICS Performance Tuner ONLY) Maximum Power on the MB C450 AMG and AMG C43 with the 3.0L M276 engine: 442 HP, 466 lb-ft of torque.

The Dinan unit seems awful pricey. Comparable features/performance seem to be available from both BMS JB1 and RaceChip piggybacks:

I've posted some info on RaceChip Ultimate in a C43:

There are multiple threads on the BMS JB1, including this one:

Looks like RaceChip is available for the E400 engines

Dinan has the warranty. Just in case mercedes doesn't cover any mechanical warranty since you jacked the horse power and good chance they might not cover it.
I have the BMW dinan kit on my M3 with warranty coverage from Dinan.

I just wanted to let everyone know in case they are considering the Dinan kit.

MrMeth90

curious what they rob people for? How much?
Thanks

On the website it says 1 hour labour so I don't think its that expensive.

I guess we won't really know how much of a performance increase this thing gives the C43 until someone takes it to the track and tries to run some numbers. The horsepower and torque gains are negligible compared to an ECU tune, so I am not expecting too much and it costs about the same as some of the full ECU tunes.

Dinan dynoed the C43 at 415hp at the crank and the piggy back give you max 442hp- a difference of 27 measly horses at the crank. Track numbers will tell the story but remember, most ECU tuners are getting 100+ horsepower at the wheels. As for the warranty, anyone who tunes their car using any method,is taking some sort of risk, if you want to believe in warranties that's your choice- but its not an iron clad, reimbursement, if your motor blows up or your turbos malfunction.

lt1camaro

I mean, Dinan is the most famous BMW tuner who has always stood behind their manufacturer matching warranty. They will cover absolutely anything that goes wrong that the manufacturer wont cover due to the tune. You can spend the same amount on a ECU tune but if your engine blows, then you are on your own.

I hear what your saying and it is a great warranty and all, I know Dinan is a very well respected company.

I am saying that if you only get 27hp increase is that worth the $1399 even with a warranty, well not in my book.

subzero05

I respectfully disagree as the dyno reports Dinan is showing illustrates to me that MB is underrating the actual performance the car makes. Dinan is simply stating what they actually measured when running the car in stock form on their dyno I presume. if you simply use stock posted numbers as issued by MB vs. the numbers posted by Dinan the actual gain is quite significant. The warranty is certainly worth something , plus they are about the only company out there that submits their products for emissions approval, including California which has the strictest regulations of them all. That in itself is worth something as well. just my 2 cents

subzero05

well that I cant really argue with as it is a bit of a dis-service to themselves by doing this

Lazz83

I respectfully hear what your saying but as far as real world horsepower goes, measuring HP gains at the wheels and not the crank, is the gold standard. I know Dinan is a fine company and makes great stuff. It doesn't really matter what Mercedes claims the HP to be, its what it is actually measured at and how much more HP Dinan's product can add. According to them they measured 415Hp stock and there piggy back brings that number to 442 hp a difference of 27hp. I also think there measuring of 415hp at the crank is incredibly optimistic- I read one dyno chart where AMR got 375hp stock at the crank, so 415hp sounds really skewed.

Thanks for the feedback. No device is worth it if it has bugs. After a month the device continues causing a P0236 code and disabling the boost.

I have sent a email to the Dinan installer.

Since the Dinan Tuner device continues to cause the P0236 fault code and disables the cars boost it is clear to me that cleaning the connectors was not the fix. Since Dinan has no idea what the problem is I would like to have Dinan refund me for the full amount including the installation cost. I know Dinan is a respected and trusted company and I believe Dinan should accept full responsibility for releasing this product that is not fully tested and should reimburse me for the entire cost of the product and installation. If you would request this from the Dinan rep and let me know I would like to get the Tuner removed from the car.

Lazz83

Bump

Lazz83

This is great information and good to know. How was the increased performance before the code was thrown?

Let us know if you get the refund.

Thanks for posting.

Sad. I began using a Racechip GTS black a few weeks ago. I like it. My info is only subjective.

Wow...I'm glad I haven't bought a Dinantronics Elite yet, and sell my Dinantronics Sport...

subzero05

SOunds like were talking about one instance, vs the units in the field .

MrMeth90

I have had the same thing happen to me. Dinan has not been able to tell me why it has happened nor did they seem very concerned...
