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

[ThomasM4]

I think anyone considering getting Dinan (myself included) understands the gains aren't as much as JB4. It's about the warranty and not having to worry about the dealership giving us problems. More about piece of mind, I'm sure plenty of people have gotten away with jb4 and warranty work but I couldn't imagine something going wrong with my brand new 75k car and having to pay to fix it out of my own pocket.

Don't know how annoying it is, but it is perplexing to say the least. One would think that the marketing geniuses at BMW would want to state the correct HP as the raw number of HP is what sells cars. I can't tell you how many times I get asked how much HP my car has. The raw HP as it seems, per Dinan's dyno is a big number and most likely would sell more cars than some reduced weight figure, one which to put it gently, was an overstatement. So you de-emphasize the HP and over-emphasize the weight savings, which the public at large (not enthusiasts mind you) really doesn't care or know much about. Even more confounding is that both numbers seem to violate EU regulations, thereby unnecessarily exposing a potential enforcement action with BMW. While unlikely to be challenged, BMW is exposing itself unnecessarily--German auto manufacturers (and corporations in general) are usually very risk-averse. So a poor marketing and poor legal decision. Maybe this is why BMW is looking to outside leadership at "M" rather than promoting from within.

Also, for everyone into the "JB 4 produces more bhp than Dinan" camp, don't forget that the Dinan tunes are designed for producing consistent power, flogging on the track, and are tested under adverse weather and heat exchange conditions. While not the best tune to win a couple of drag-races, this is the type of tune that you know will produce consistent, safe power gains (esp in the mid-range), generating less heat (important for tracking) with a full warranty backing it up. There have only a few tests of the Dinan warranty that I know of and all were either covered by Dinan or a combination of the dealer and Dinan to satisfactory resolutions to the owners of Dinan products. If I had a turbo engine, I would highly consider this type of tune.

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

Get out of here with all that logic and reason. It's pointless to argue anyway, since people's minds are already made up. Some people get it, some don't. Crapping on one product versus another is tactless anyway. Just judge your risk versus reward and go with it.

So I couldn't wait to get the Dyno done. I'll have a full write-up shortly, but here are the messed up Dynos. We tried for two hours to fix this, but I think they are accurate other than the two blips in the graph. The shop is going to call DynoJet and ask them what is wrong. It seems to be something with the coilpack reading.

I think you'll get the idea. My butt dyno agrees with the findings. I am more than pleased, and I don't care if JB4 makes more power.

Not bad. Nice torque gains.

[Tony007]

I really like Dinan's HP curve. Doesn't drop off up top like the other dyno curves we've seen.

Can't wait to hear about your impressions on the way it drives...

[ThomasM4]

Nice, I was expecting it to make 440 rwhp so thanks for confirming. I'm scheduled to have mine installed tomorrow at my 1200 mile service along with my H&R sport springs.

[Black Gold]

Not bad. Looks like more power can be gained while maintaining power to redline

Any ideas on what boost its running?

Intrrested in stage 2 and bmws inevitable ppk

[/// M sa]

So compared to JB this is missing over 60 or more whp?

I'm not sure I would call it missing. Calling it more conservative makes a bit more sense to me.

I aim to mean no disrespect, but homemade looking products don't inspire me.

I believe any flash is better than a piggy back... I had tons of issues in the past with piggy backs so I may go with Dinan if they come out with stage 2 etc. Flashes are more stable than a piggy back or at least it was before. How much different does the dinnan feel from Stock?

[Mandi90TT]

You do know Dinan is still a piggyback?

It is indeed. They say that the Dinan can adjust the fuel and other piggybacks cannot do this? Is that in anyway true?

[Revartr]

I'd be very interested in a Stage 2 or E85 application from Dinan. I'd like to be pushing over 600 at the crank with a full exhaust, airbox, tune, etc.

Thanks for sharing Money2356! We look forward to seeing updated numbers once the dyno issue is corrected. Glad you're enjoying it so far!

When I talked to Dinan they said they will most likely only be offering 50 state legal tuning solution. Stage 2 will involve an exhaust and most likely an intake, no downpipes. I would guess well will only see 10-15 more HP out of Stage 2. So if you have Stage 2 on a nice cold day you might come closer to 500 whp.

Personally, I just wanted to confirm that my $2,500 was spent on mid range, usable gains. I got what I was hoping to get and a little extra.

I promise I'll get a thread up in the next few days after having a little more seat time with the tune installed.

How much worse is traction now post install? The +50tq is the surprising part to me.

No discount at all from the dealer on the tune? My CA said I could definitely get one.

In the end if you're happy with it that's all that matters. I look forward to the full review once you've driven it a while. Every tune has pros and cons IMO. My Evolve tune for my E9x made more power but I always felt the BPM had more driveability. It all depends on what a person wants.

[Mandi90TT]

You don't NEED a tune to run with downpipes. From the dynos I have seen of folks with downpipes and no tune, there has been some pretty good gains, not in max HP/torque, but quicker spooling of the turbos, and a greatly increased area under the curve, which is really what matters.

The tune can remove the CEL that MAY come with running downpipes, there have been conflicting reports on people getting a CEL and others not getting a CEL.

[Newguy123]

thanks for posting but I would be a bit disappointed. Yet again dinnan falls way short of the competitior & the consumer pays 2-3x the price. :/

I'm not worried about the gift-wrapping, but more interested of what's inside the box:



JB4 performs very well and has a pretty good track record on N54 and is bringing that to the S55. Also looking forward to seeing what tunes from other companies can do as they are released.

Where can I find the dynos you're referring to on these cars with before and after downpipes only? I've looked everywhere!
