Max HP Gain 44 Max Torque Gain 77 Peak Horsepower 364 Peak Torque 407 Stock HP 320 Stock Torque 330 Included Notes D-TRONICS Performance Tuner, Dinan® wiring harness, Dinan Stage 1 software So basically, for $2000, we end up with the same specs as an F30 335i which also costs $2000. I thought they'd surely do a little better with M235i other than the usual tune. At the very least they could have prorated it since the added performance isn't all that much. And no, I'm not a Dinan hater. I actually want to give them my money had the cost to performance ratio been a little more even matched with the other cars.

Yes it is expensive. There is no denying that. Spec wise when converted to WHP the specs are damn near identical to the dyno run with the JB Stage 1 tune from another thread down the list and that also had an AFE intake on it. Not that the intake would make that large of a difference but still but that dyno run also didnt have the EWG connector so the lack of that coupled with the addition of the intake it may be a wash. So for 4.5 times the cost you get similar power but with a warranty essentially. I for one, am actually surprised at how HIGH the numbers are. Typically Dinan numbers are lower than any Burger tune just because they tone it back a little because of the warranty.
As for the comment on it making the same power numbers as the 335i, why wouldn't it, it the same engine after all. The 235 is just getting some additional power from MPPK software that is built into the stock model. What's interesting though is the HP numbers are identical between the 335 and the 235 although they start 20HP apart while the torque numbers increase ~30, the same as the beginning delta between those 2 models. Why would one go up but not the other (even a lil bit given the starting differential)? Is there some HP cap on the n55 that Dinan feels is getting a bit too close for comfort and therefore backed off on that number? I don't know, it just seems odd. Bottom line like every Dinan vs. whomever conversation goes; is the warranty important to you? In this case given the specs are damn near identical to the burger tune it might be an even more valid point. That said, it's still to rich for my blood given the actual performance gains but for those who value the warranty / peace of mind enough then it may be worth it to them. |

Maybe a Dinan stage 2 might make more sense money wise. But apart from that I still feel the Armytrix exhaust with 25WHP increase makes more sense for the money. And for about $700 more you can get the stage 2 JB4 with CAI if you decide on not going Dinan.
Or if you really have lots of money you can do the Dinan Stage1 tune and the Armytrix exhaust with a CAI. So Many options for everyone to decide. Bottom line is the more tuners doing stuff the better it is for all of us.

+1 to all this. The 235 and 335 should have the same HP/Torque numbers. They are the same engine. I agree, it is more interesting that the Dinan numbers are so close to the Burger numbers as Dinan is usually very conservative in their tune. |

Wait a minute!!!! People are complaining that a $2000 upgrade, that keeps car under warranty, is too expensive; but yet are willing to go out and spend way more than that for a non-existent M2 that will have even less power/torque than the Dinan mod. WTF!!!
Let BMW shove the M2 marketing BS up their A@@. I will be Dinan all the way, driving a monster that is going to eat M2, 4, 5, and whatever new marketing BS number BMW comes up with. |

Ok.. so now that they've fixed their website it's $45/hp. The JB4 Stage II running Map 2 could get you there and further for $9.25/hp (assuming ~65hp gain).
So it's all about the workmanship and warranty now.

Am I missing something? I thought the Armytrix setup was around 3k? It's a full exhaust and it will most likely void your warranty say you blow or damage the turbo.
Again I think some of us are looking at this tactically and strategically. Tactically it makes sense to mod based on the best bang for the buck. Strategically Dinan makes more sense... if you go without a warranted vendor then you are pretty much flying blind if something happens to your car there is no peace of mind.

About the price all I can say is I was quoted $2150 so no idea where you got the $3,000 from.

Nice response from them. I buy into it...I mean you pay for quality just like any other product out there.
I saw banners for Dinan at the local BMW dealership here in the service area, does that mean they will install and service it if there are problems with the system? Or do they just sell them and you contact Dinan directly if there are any problems?

If Dinan is using the same piggy back technology, the results are pretty identical, and they would not put a product out there without ample testing. Then doesn't the idea of voiding warranty for the cheaper piggy back seem less significant now? Yeah I know their answer is that they have more testing done but doesn't that just sound like a company talking points memo?

I believe, and just my thought on this, the Dinan box is able to copy the existing BMW software onto their ECU box. Using like he said, they have engineers who have learn how to crack their code but it has gotten more difficult over the last few years. One of the reasons why he doesn't offer this product for every BMW model. By copying the code to an external box, he can tweak the code that he needs to adjust and leave the existing code in place, untouched. So, you are now paying Dinan for two things, a new ECU box and the transferring of his code. Given his prices have stayed nearly the same over the last 10 years that is not a bad deal.
As for going to Stage 2, 3, etc. when they become available you only pay the difference between the stage you have already purchased. If you bought Stage 1 at $2000 and Stage 2 is $2400, you pay $400 for the upgrade plus labor time and local taxes. |

Yeh might make more sense money wise for the stage 2 or 3. I'll look at it when it comes out

The fact that they have been around for 20 years to say it says something though.

Anyone with detailed knowledge of this please correct the next statement if needed but this is how I have it interpreted... My understanding of the JB4 and others like it is that they increase the boost and a few other parameters leaving the stock DME to adjust most related settings to fit the new levels it sees. This in turn sets faults / codes within the system. The box is then constantly clearing these faults so no CEL appears. So while you are given the impression that everything is working fine in the background there are still errors happening. They are just getting cleared faster then they can be displayed. Essentially they are lying to a few key sensors and letting the stock DME figure out the rest. The Dinan piggyback on the other hand is a bit more thorough. I'm reading in between the lines a bit here so I could be way off base so take this with a grain of salt. By the description I am understanding that they actually are adjusting all of the signals, or at least the ones that may set off faults / codes with the goal of not having to clear anything. If that's the case they technically have more control and can adjust things to be smoother performing. Perhaps the stock DME auto-correcting itself is just as smooth and there is no advantage. Only a direct comparison sitting in a vehicle on back to back runs would be able to answer that. The bottom line if my interpretation is correct is they are lying to more signals than the competition. They are a better liar. lol If that is the case then yes I can see a substantial bit more R&D there hence the increased cost to go along with a warranty. Now whether that method is any better then the competing brands method is really up to the person buying the tune. On one hand in theory there is more control. On the other it appears you get the same end result for quite a bit less. I think it ultimately comes down to preference (read: if you want a warranty) and the highly controversial term of "drivability" where each persons version of that is different. |

@HelzRage I think you are spot on in your thinking. Watching the video posted earlier and also reading the response from Dinan themselves, plus looking at the actual hardware from Dinan, it sounds like that is exactly what is going on. Basically the Dinan piggyback is a more complex unit than something like a JB4...it monitors more sensors/signals and sends out more signals to more sensors to make the power increase smoother and safer for the engine. Again, it makes sense to me and I buy into it. For me, it really comes down to which one would provide an OEM like experience? Which would make it feel like it was BMW themselves that incorporated into the car from the factory?
And on a side note, anyone know if Dinan ever does semi-annual sales like APR?
