Dinan DINANTRONICS Performance Tuner Stage 1 for BMW F80, F82, F83 M3/M4

I would not rely on a chassis dyno chart to draw this conclusion.

BMW do quote a power plateau from 5500rpm to 7300rpm and acceleration is all about power for a given road speed, it is basic physics. As I stated previously, the revs need to be kept above 5500rpm in the next gear to maximize acceleration. There is no way around this.

Not sure in this case if the theoretical applies over practical skill. What the heck is physics? OK I give, I'll shift higher!

Try it, you will improve your lap times

I want to chime in here in a few ways:

1. Dinan sold to Driven Performance Brand Group in 2013, which also owns B&M Racing and Performance, Flowmaster, and Hurst Driveline Conversions. They appear to be a division of private equity firm Dubin Clark. When the sale occurred, some long-term employees departed. I just want to disclose that while Dinan has been around for ~40 years, they changed ownership 1 year ago.

2. Unless corrected by Dinan, these charts are a chassis dyno with a predicted drivetrain loss added back in. For example, their dyno may have yielded 414whp stock and 444whp with the tune, to which they applied an equal 17% drivetrain loss back in. This would yield "484 crank hp" and "519 tuned crank hp" results in that graph.

Please note that this is not an accurate way to advertise crank hp. So unless they correct this perception and confirm that these is engine dyno'd, then they are ///Marketing falsely.

3. Dinan is an outstanding brand and has outstanding quality. Historically though they've defended their higher cost for tunes through quality, warranty, and because a software tune took alot more time to develop than a plug n' play solution.

This new product maintains that historical price point, but is not a re-write of the ECU/software. You can make your own assessment of that.

4. A warranty is essentially an insurance product. You pay upfront for an amortized risk product. Dinan tends to provide very safe, and semi-conservative tunes with extremely low incidence of problems related to the tune. The tune is ~$1000-$2000+ more than comparative tunes that do not include a warranty. Some of that cost is the dinan brand and quality you get, and some of it is the dinan warranty. Considering the very low incidence of problems with their tunes (historically), it is a fairly costly warranty product.

5. Please remember this is not yet a proven product. Dinan has an excellent and well deserved reputation, and I'm sure they put out a quality product here, but let's remember that this tune and engine are brand new. The engine itself may have flaws like a turbo oiling problem we don't yet know about, and may fail at 20k through no fault of the tune. Please remember that.

Just wanted to offer my .02

That is a very pertinent piece of information.

Thansk for sharing

Dinan, any insights on the above?

I had a baseline done today. I forgot to bring my USB Flash Drive to save the files.

88.7% Humidity

Dinan gets installed tomorrow morning!

Good numbers money! Thanks for posting.

If it's breaking traction when entering 2nd and 3rd it's kind of a wash right. Might be faster if it didn't right?

Nice numbers, when is the follow up dyno? Tomorrow as well?

[Black Gold]

thanks

can you post non corrected numbers for both when you go back to the dyno? STD corrections are typically too optimistic, and are not universally accepted

strong results!

SAE was 422/398. I'll get the videos/photos/graphs up later.

Probably next week. Sorry to keep you waiting.

[shortseller]

Excellemt numbers, and as others have already said, thank you for doing this and posting results for all to see.

Make sure to post your driving impressions in the meantime. Apart from the net gain in power, the effect on driving dynamics is pretty important.

[M3guy3]

its so annoying how BMW underrates the engine beyond belief. i understand the need to underrate the car little. BUT geez

i would rather the factory stated power be 450-460.

I would much rather that they underrate it than overrate it like Ford did with the Mustang.

i agree, i would rather it be underrated also . but there is a limit IMO. I can understand underrating 20HP. but BMW underrated like 50HP.

its just annoying how the car is labeled for 420HP, but it probably has more power than a C7 corvette.

Are you more worried about how fast people think your car is then how fast it actually is?

i guess in this BMW time, its to much to ask for both.

You should really consider JB instead of Dinan.

I got a chance to drive both here in Miami last weekend and the JB felt a lot better than the Dinan. Much better throttle response with the JB on and def more noticeable power gains than the Dinan.
