Dinan early in the year criticized existing piggyback boxes stating they were poorly calibrated. When BimmerBoost learned Dinan was to release his own piggyback boxes, we questioned whether this made him a hypocrite. Dinan read this criticism and offered a professional response that BimmerBoost and the membership appreciated.
A lot of BimmerBoost members use piggyback boxes and now Dinan is releasing his although at quite the price point. What this means is that Dinan concedes that he can no longer flash tune the modern BMW cars. That is not solely a Dinan issue it is an issue for the entire BMW aftermarket tuning industry as BMW is locking these ECU's down. Nobody is flashing the F30 335i for example and that is because of the measures BMW has taken to lock everyone out, Dinan included. BMW just is not any fun.
If you are wondering why turbo upgrades have not come for the N63TU 550 models of the F10 M5 with its S63TU V8 part of the reason is that nobody has a real grasp of the ECU. Alpina can offer turbo upgrades but that is only due to what BMW gives them. The Alpina B7 models for example feature upgraded N63TU turbochargers yet nobody else in the world has a working turbo upgrade kit on the 750i other than Alpina because nobody else in the world has Alpina's relationship with BMW.
Dinan realizes now that he can just not brute force his way in. Dinan has some very sophisticated computer equipment and some very sophisticated Caltech grads working for him but BMW has a lot more money to throw at the issue of locking people out of their computers. So whatever Dinan or any other tuner has, BMW has that times infinity with how stuffed their coffers are from diluting the lineup. The best engineers in the world work on keeping tuners out of these cars and they are succeeding to a degree they never have before. Throwing computer power at these new ECU's trying to get in just is no longer a viable approach.
So where does that leave Dinan? Where it leaves everyone else, with a piggyback. What Dinan is claiming though is that his piggyback unit is somehow better and worth the price. Is it? That has yet to be determined. It very well might be but speaking from experience viewing the evolution of devices and many people competing in this sector it is the not the most expensive device that is necessarily the best. A certain someone who used to claim that has been laughed out of the BMW tuning market. Furthermore, many BimmerBoost members tweak their tunes themselves so the base tune and approach used in the box often gets changed extensively. What type of flexibility does the Dinan D-Tronic hardware have? For $2000 it better offer a bunch.
Dinan claims his unit is the only one that is emissions legal in all 50 states, but it isn't. Read this: The D-TRONICS Performance Tuner was designed and built to be the only tuning box on the market that is emissions legal in all 50 states. At the moment this product is emissions legal in most states – the product is in compliance with US Federal EPA Memorandum 1A, or this product has not been found, nor is believed to be, unlawful for use under the provisions of the Clean Air Act. Currently this product is not legal for sale or use in California, and states that have adopted California emissions standards, on any pollution controlled motor vehicles
Dinan just ran into the same problem BMS is having with CARB (California Air Resource Board) but what is written by Dinan makes no sense. One sentence says it is emissions legal in 50 states and literally in the same paragraph it states it is not legal for sale or use in California or any states that have adopted California emissions standards. That makes absolutely no logical sense, who wrote this?
Dinan claims a gain of 64 horsepower on the F30 335i. Ok, where's the dyno? If you are going to try to muscle in on the established piggybacks the owners are used to viewing data. Just using the Dinan name is no longer going to fly. We want to see numbers, we want results, we want the best option that is proven. We do not want people living off past accomplishments. You want the money? Show me what it can do or you will not get it.
Additionally, since this is a piggyback device that is removable the appeal of the Dinan warranty is not as large as it was with their superchargers, stroker motors, intakes, flashes, etc.
Dinan has an uphill battle here. Additionally, $2000 is a lot in this market. Not to mention that Dinan takes it up to $3500 for the F10 M5. Charging that price with absolutely no dynographs, no timeslips, no videos, no logs, and absolutely no data is banking on the stupidity of M5 owners. Which, in all honesty, is not even a bad bet if one were to read some of the M5 forums out there and the reverence some of them pay to the Dinan badge and Dinan points. If Dinan wants to claim his box is better, he needs to prove it with something of more substance than because he says so.
On Bimmerboost the points we are about are the points on a dynograph. This is not going to fly here. Good luck to you Mr. Dinan, you are going to need it.
The biggest benefit of Dinan's D-TRONICS Performance Tuner is our ECU has the…
"…capability of setting an optimum target lambda (fuel mixture) as well as correcting short term trim which is the difference between target and scheduled fuel mixture. By matching these two correctly we can reduce knock sensor activity which will make smoother performance, protect the catalyst, increase power and allow us to make it emissions legal."- Steve Dinan
The Dinan® Difference is possible by employing a full staff of talented engineers that are well rounded in all aspects of their job. Manipulating these signals with an adept hand all the while keeping an engine running at its best and with the most reliable power is what Dinan is all about.
Plug-in tuning devices all have one thing in common, they send a modified signal to the factory ECU, telling it the boost pressure is below target values. This then causes the factory ECU to raise the boost pressure to what it thinks is the correct value. This modified boost pressure signal causes errors in fuel mixture and ignition timing. These errors can cause the on-board diagnostics systems to set faults, but they can also cause exceedingly high catalyst temperatures and a loss of power. In addition, when power is increased, exhaust gas temperature will increase as well and this must be countered with a slightly richer air/fuel mixture. The D-TRONICS Performance Tuner uniquely has the capability to adjust target Lambda, correct short term trim as well as ignition timing errors induced by raising boost pressure. This enables Dinan® calibration engineers to optimize air/fuel mixture and ignition timing at elevated boost pressure throughout the entire gamut of engine RPM and engine load. Additionally, the ability to correct short term trim corrections (the difference between target and scheduled fuel mixture) remain within OEM specifications. This minimizes knock sensor activity, which in turn means smooth engine performance, catalyst protection and power increase, while this is also required to make the car emissions legal. Dinan engineers have worked for two years on the D-TRONICS Performance Tuner in efforts to provide BMW enthusiasts with Performance without Sacrifice.
Dinan's comprehensive warranty program, introduced in 1997, provides superior warranty coverage to that which you would find elsewhere. If your vehicle is currently covered by the vehicle manufacturer's new car limited warranty, Dinan® products are warranted for the remaining term of the vehicle manufacturer's new car limited warranty. The manufacturer's new car warranty is limited to 4 years or 50,000 miles (80,000 kilometers in Canada), commencing on the date of first retail sale or the date the vehicle is first placed in-service as a demonstrator or company vehicle, whichever is earlier. Dinan's warranties are transferable when ownership of the vehicle into which the Dinan® products were originally installed is sold. BMW automobiles can now be performance-tuned without the associated concern of negatively affecting the new car warranty coverage.
Designed to be Emissions Legal
The D-TRONICS Performance Tuner was designed and built to be the only tuning box on the market that is emissions legal in all 50 states. At the moment this product is emissions legal in most states – the product is in compliance with US Federal EPA Memorandum 1A, or this product has not been found, nor is believed to be, unlawful for use under the provisions of the Clean Air Act. Currently this product is not legal for sale or use in California, and states that have adopted California emissions standards, on any pollution controlled motor vehicles. We are however in the E.O. process with the ARB and are confident that the D-TRONICS Performance Tuner will be emissions legal in all states in the near future.
There is more to a tune than just cranking up the boost. Power needs to come on smoothly and in a predictable way to make the car as fun to drive at wide open throttle as cruising around town. It is your BMW, but reborn with new found acceleration and speed.
