Dinan vs ESS tune

Hey guys,

So I noticed there was an absence of dinan information running around this thread, so I wanted to ask if anyone had the dinan tune, or if anyone from ESS knows the difference between the two. I'm especially intrigued since it's the cheapest tune available and it would be covered under warranty.

Thanks!

dinan is a little more conservative from what i have gathered. i would honestly choose another vendor but if warranty is a concern just stick with dinan to sleep well at night

In terms of performance it is hard for me to make a comparison since I added the ESS tune when I got the blower. But I had a couple of issues with the Dinan tune during cold start-ups... it would through a CEL code from time to time. Never gotten a code with the ESS tune.

Last, the ESS tune allows me to pass inspection with the cat-less x-pipe. In NY you'll pass with only one stored fault code. A cat less system (even with a tune) will normally store two codes, making it impossible to pass.

So I say ESS all the way.

Hope that helps.

strange that you had issues with your tune. I've had it since it was first available and have had no issues. I also updated to the stage two tune since I'm catless and have yet to have any issues

I second. I have the Dinan mid and rear exhaust and got the tune and loved it. It is conservative but I did care about stretching the cars limits..... Then I got the ESS Super Charger lol. And love it.

B4 you get a tune find out what your plans are for the car in the future. My point is I waisted my money on the 1st tune since I ended up SC'ing the car.

I've been thinking of the full Akra and leaning to the Dinan tune.

The main reason for me is warranty. I understand that the Dinan warranty is not factory, but it's supposed to be very good. Also with Dinan being partners with BMW (maybe a little less now), I figure that BMW is not going to hassle you as much if there is potential problems.

Our BMW dealer in town does not like to deal with Dinan cars so it wouldn't matter. With the Hex flash tool like VF Engineering's you can always flash the car back to stock at any time so your warranty won't be affected.

True, you can flash back to stock, but BMW is going to be able to see how many times the car was flashed. I would think that warranty is going to be voided- correct me if I'm wrong.

There was a case of a 911 where warranty was denied because the car was previously flashed. The ECU's are probably different than BMW's, but Porsche was able to see that it was previously tuned even though it had the stock flash on it.

My differential bolt snapped and the diff nearly fell out. I had bolt ons (dinan pulley, intake, ESS tune, MPE exhaust), but was fully covered under warranty as there was no evidence of abuse. Someone from BMW NA came out and took a look at the car (and presumably the ECU, given every other story about diff issues) and gave it a clean bill of health. I did flash back to stock using the portable ESS FlashLoader (highly convenient and can keep in your glove compartment) prior to being towed into the dealer.

Yes, in my case I passed NY inspection with the ESS tune. You pass with one stored code, fail with two. The tech plugged it into the DMV system, and only one stored fault code was found, so the system issued the new sticker.

That was with the ESS tune, SC, Dinan mid-pipe, and Eisenmann Race. Please note, the second you pull into the dealership or any state inspection facility they'll know what is going on when you run a full exhaust. Although the DMV system can be "fooled", a visual inspection will give you an automatic no-go. Besides the sound and smell is a dead giveaway.

So basically the tune in regards to passing the state inspection is just the last box that gets checked.
The place where my car gets inspected, they dont give two shits about smell or a visual inspection.
Still would like to know if BPM tune allows ny inspection to pass.

You do not have BMW warranty with Dinan parts or software. Most dealers put Dinan mods in the same basket with any other aftermarket mods. I would much rather just re-install my original software thru the ESS E-Flash when I go in to the dealer and have my factory warranty than deal with Dinan VS BMW. I have gone in several times for service and warranty work and I always just reflash to my original stock file.

Dinan also has no remote tuning options so you have to take the car to a Dinan dealer whenever you need a change, update or reflash. For me this alone is a deal breaker. There is also far less in options with Dinan software like Valet mode, Cold start delete etc... That being said I would trust my car with Dinan if there was not a better option available but there is.

Performance = ESS tune
Options= ESS tune
Ease of installation= ESS tune
Warranty= ESS tune

All you have to do is clear the faults prior with the Hex tool for CAT fault codes. It takes about 15-20min of a drive cycle for it to trip the light again. No reason for the dealer to drive the car for that long unless you have a serious problem.

The technicians can not see that at the dealership, only BMW regional engineers may see that, but if they can't prove the tune is physically on the vehicle they are not legally aloud to void your warranty.

ESS all the way Dinan is a great product don't get me wrong, very reliable. When it comes down to POWER ESS all the way and to be honest I haven't ran into or herd of any issues with the ESS tune!

Now back on topic.


I had the Dinan stage 1 and stage 2 tunes on my M3 before getting the ESS Supercharger. I really liked both Dinan tunes and they definitely provided more power. I never had an error code from either of their tunes. They drove smooth and had some added power when I wanted it. I was wanting more power so that is why I went with the ESS Supercharger.

Now that being said, ESS did dyno my M3 before putting the supercharger on and for fun they put their own tune on my M3 and dyno'd. They made about 15hp-18hp more than the Dinan tune. Keep in mind that this was only for fun as they were installing the Supercharger on my M3 later that same day.

In summary, Dinan has always been a little more conservative with their products, but their power increase numbers are accurate. Keep in mind that Dinan has to warranty all their products so that factors into the cost and into the level of power increase that they feel comfortable with. Of the two tunes Dinan vs. ESS, the ESS will make more power for sure. Their support has been second to none for me, even with my 1M.

I hope this helps you out with your decision.

One important thing to consider IMO is the history of the tuner. Dinan has been around for so long and is top notch no doubt. I know their warranty stuff with BMW is a bit different now but the fact that BMW did warranty their parts speaks volumes about their products. Even their warranty now is still outstanding. The history and quality of Dinan is unsurpassed. They are BMW's "go to" tuner! They have always been ranked number one in my book and many others. It's not only about the power or numbers a product puts out. As a company, it is VERY hard to put anyone ahead of them!
