DINANTRONICS Stage 3 (STD & CP Models) / High Performance Heat Exchanger

[NOLATom]

I got the stage 3 about 5 weeks ago and have driven it over a thousand miles so far and this is what I can tell you. Out of 20 initial runs, 10 of those felt no different than stock. Some even felt like there was less power than stock. Another 8 of those runs felt like there was more power. 2 of those runs, it threw my head back into the seat, which has never happened before.

My first day at the track in NOLA with it, I had a misfire on cylinder 1 and 6 and the car went into limp mode until restarting it. Changed the gap on the plugs and haven’t had a misfire since, but even just taking it for some daily drives, I have found the same issue. Sometimes there is a notable increase in power and sometimes there is a noticeable lack of power. I should have had it dyno’d but the shop that did some work for me caused damaged to my car and I decided to not let them dyno it after that, but next time I am near a shop that does the dyno, I will have it done.

Only the hardware, disconnect the piggyback.

Damn that is a sad story. Seems like you have a very inconsistent piggy back tune, I was not expecting that from Dinan.

But their gains are so minimal, I can't believe they still get customers from S55 platform.

Their hardware on another hand is very good, that i would purchase, but never their tune.

Have you had a chance to retrieve fault code for what you are experiencing and contacted Dinan's tech department to get some type of input ?
Also, download the free phone app and make sure you are on the correct tune file.
Personally I know a few local S55's with the same setup as you, and I have not heard of an issue other then the cars are fast.
Hopefully you can get this intermittent issue resolved.

I have Dinan Stage 3, intake and exchange with aftermarket exhaust system and mod pipe. How much whp are you guys proposing out of your parts alone?

You probably got a healthy 10-15whp Power gain

You sure that's not crank!!

I posted this in another thread but also wanted to post it here, hopefully this will be beneficial to anybody who may be considering getting Dinan parts/tune.

Dyno chart: Stock, Stage 2, Stage 2 + CAI + Heat Exchanger.



I know I said earlier I am not interested in the heat exchanger .... I changed my mind, lol.

Bottom line: 450whp/513wtq, gains of 41whp/92wtq.

Don't be fooled by bottom and middle range difference. CAI and heat exchanger have nothing to do with them. The fact of exact same top end curve leads to something you wouldn't like to hear. My educated guess is ambient and/or vehicle operation condition difference is responsible for power gain at bottom and middle.

Perhaps, ...., same dyno, very similar ambient conditions, either way I am just pasting dyno results for a Stage 2 tune with CAI + HE.

was the dyno the same day , and same person operating it?

Stock and Stage 2 were back-to-back, Stage 2 + CAI + HE was on a different day, everything else the same.

Not hard to spot the Dinan haters, seems that nobody questions 'gains' on other tunes but Dinan's.... Don't be fooled by the criticisms, my educated guess is that the competition sees $$ going out of their pockets every time there's a good Dinan review... ( I have no idea why I feel compelled to defend Dinan but it pisses me off when the conversation turns nasty whenever Dinan is supported.) Yes, ambient temp, time between tests and a number of other independent variables should be accounted for in any findings....good questions.
PS I have the Dinan thrust arm bearings, but nothing else...
Thanks for posting the results, and maintaining a detached perspective, the 'pole sitters' appreciate it! The 'mixed' review of the stage 3 is more puzzling and a bit disturbing....it makes no sense unless there is a vehicle problem.

Unfortunately since my feedback on Dinan stage 3 I have had issues. I have posted it in another thread to see if I am the only one. At least one other person has had the same issues as me, which is misfires after the Dinan stage 3 install. Dinan is the only work I have done to the car, so I can say with some certainty that it is Dinan related as the problem did not exist before the tune.

[silverstar335]

I view my posts on this specific topic as an opportunity to share my unbiased perspective and experince. Hopefully, this will help other members make a more informed decision when deciding which path to take when tuning their M’s. In a nutshell, Stage 2 + HE gives you 40whp and 90wtq, the CAI are a noise box that did not give me any gains. I have a dyno pre/post the CAI and please dont ask me if I had that done the same day I had those installed . I highly recommend the Stage 2 + HE or just the Stage 2 tune if you are concerned about having/keeping a warranty. If warranty is not a consideration that plays a key role in your decision making process, get whichever other tune meets your specific needs (JB4, BootMod3, Gintani, etc.) .

Puzzling.
Any word from Dinan?
Of course it could be a manufacturing problem (pretty rare though based on others complaints) or an interaction between unknown elements (manufacturing variance and/or wear and tear in your car AND the Dinan kit) or all of the above. Thanks, and continue to keep us up date!
