What you are about to read is Dinan's response to those questions. Additionally, BimmerBoost is not a BMW enthusiast website that shies away from strong opinions or raising awareness of controversial topics. That said, we also believe in providing the complete picture and that is why Dinan's request of being able to address the topic is gladly granted.
You are an intelligent human being capable of deciding for yourself. BimmerBoost will strive to bring you all the information and sides to a story as we always have so you can come to an informed conclusion.
Additionally, BimmerBoost is happy to take Dinan up on their generous offer of touring the Dinan facilities to see firsthand what takes place. These arrangements will be made in private and a report of BimmerBoost's visit to Dinan headquarters will be posted at some point later this year.
We recently saw your post regarding our new Turbotronics project and wanted to clarify a few points to make sure your readers have the correct information. I stand by my comments on "Tech tip Tuesday". Even though we are making an ECU we are still believe software has superior performance and reliability when compared to an ad on ECU. Having said that the new Bosch ECU has proven more difficult to crack than previous models so we have been forced to go the ECU route. BTW this is Dinan's 16th Turbotronics ECU because we used to make them a long time ago but when we got very good at software we went away from them because of the obvious advantages.
“Tech Tip Tuesday” was also referring to the existing piggy back boxes on the market. Our goal wasn’t to imply that a piggyback box wasn’t a viable tuning solution, but rather the current ones lack sophistication in which is why they make less power, have more drivability issues, are more prone to setting faults and are not emissions legal. I also mentioned that a box would have to be much more sophisticated in order to work properly and not risk any damage or malfunctions with the vehicle long-term.
The reason our software is more expensive than current piggyback systems on the market is the level of work and research that is required to “crack” BMW’s factory computers, the additional cost of the 4 year 50k mile warranty and emissions certification. The cost our R&D, warranty and emission testing when compared to manufacturing the piggy back boxes I see on the market it is more likely they are making more money than Dinan soit is not about money as the person implied it's about doing it right. Most people assume that BMW gives us complete access to the computers, but that is not the case.
We have a team of 5 engineers that do nothing but read through every line of code on each ECU to make sure that all of our software allows the car to function properly, doesn’t interfere with other electronics and keeps factory system safeguards in place.
As far as the new “Turbotronics” units are concerned, (still in development) they essentially are more than a piggy back box they are a powerful ECU that has many more capabilities that the existing piggy back boxes. To help you understanding the additional capabilities as I said in "TECH TIP Tuesday" the existing boxes send a an adjusted signal to the BMWECU telling it he boost is too low and the ECU then raises the boost to what it thinks is the correct value as does ours. This false value creates errors in Fuel mixture and ignition timing. This can causesmore faults, high catalyst inlet temperatures and a loss of power.In addition when you increase power exhaust temperature will increaseand this must be countered with a slightly richer mixture. Our ECU will have the capability of setting a richer target lambda (fuel mixture) as well as correcting short term trip which is the difference between target and scheduled fuel mixture just to mention a couple of it's capabilities. By matching these two correctly we can reduce knock sensor activity which will make smother performance,protect the catalyst, increase power and allow us to make it emissions legal.
We have a lot of exciting new product in the works for N55 powered cars along with products being created for the M235i. Keep an eye on our social media channels for announcements on sales, new products and more of our Tech Tip Tuesday series.
Thanks again for your time and we hope this is helpful. If you’re interested, we would love to have you out to the facility to see our operation first hand.
