I've been working for about 20 years in the engineering of BWM Diesel-engines. (This part contains some very deep technical info and very specific names wich i can't really translate that well so i simplified this part, some words might sound weird since i could not find proper translations, sorry for that) A shortened, but technical very informative and detailed version of this text regarding negative effects of chiptuning (based on BMW diesel-engines) is worth reading for everybody who is planning to chip his engine: This changed with "Computer Aided Manufacturing" and the growing interest to safe more money in the production of cars/engines.Īlthough Manufacturers keep it low when it comes to this topics, a reader of this blog took some time to gather quite some statements of a BWM-Engineer posted in various forums etc. In a time where cost-reducing was not such a big topic, engineers sometimes used "over-sized" parts in the process. There are some Manufacturers that assume that their clients want to get quite more power out of their engines, for example many japanese brands. Of course, this text does not apply to all engines out there. Truth about Chip-Tuning: in almost all cases, don't do it!
A lot of money is paid for "chiptuning" that would be better invested in getting the bigger engine right from the start. A text that popped up in the internet and with my understanding of Engines it tells us: Stay away from manipulating your ECU! Unfortunately this knowledge does not come around enough, and this is very important for a specific industry. The truth about chip-tuning, by Philipp StalzerĪn often discussed Topic, with almost no real technical background or tangible details to make a decision if you want to mess around with your Engine electronics or not. I had the thought of tuning my future car as well, but after reading this i think i'll skip that and just let it be stock, since i plan to drive it several years. I think many people on here might want to read this, it contains a ton of interesting information on why chiptuning is more bad than good. I just took some time to translate it to englisch (as good as i could)Īll credit goes to Philipp Stalzer from MotorBlock (article is in german!) Source article First off, this is an article from a austrian blog (MotorBlock).
