![]() If you don't mind paying, HPacademy has some courses.KESS V2 is one of ECU Chip Tuning Tools that allow you to read and write the ECUs of cars,bikes,trucks tractors and boats simply connecting the tool to the diagnostic port.It let’s you quickly,easily and safely tune car performance and modify it’s component behavior in several easy steps. After that read the tuning section of the megamanual: Those two will give you a crash course. This is a good beginner's guide on tuning. You can damage the engine so try to get a very good understanding of tuning before you start making changes. If you do want to make changes to an engine's tune, you want to be very sure of what you're doing. These usually come with a USB cable to allow connection to your computer. I know with some of these, you can download the software and have a play within the program without having an ECU connected. If you want more functionality than what the OEM ECU can provide, you'll want to fit something like a Haltech, Link, Motec, Megasquirt, etc. These provide a connection for a cable to the ECU. Others will need a board added, like nistune or hondata. Some can have the OEM ECU retuned but you'll need to buy an adaptor to allow the interface between the car and the laptop. I have done the things you are asking about, in terms of BCM adjustments, I bought a VAGCOM (OBDeleven) compatible dongle and software that has allowed me to make all sorts of cool adjustments to the programming of my comforts, displays, turning off the motor sound system, windows up/down on keyfob, etc.īut, have left my tunes off the shelf, currently, until I have an experienced etune/dyno tune done.ĭepends on the car. Even though I haven't touched any settings, I have a slowly growing and much clearer understanding of what is going on. The one thing I see missing from today's advice is the redirect to (link in sidebar) Bare minimum tuning knowledge webinars. I was there when this sub was concieved and incepted, I had just bought tuning port (Cobb AP) and wanted to understand more, but they were smart enough to stray me away from tinkering with my new engine that could cost me $8-10k to replace if I made mistakes. I wanted to do the same thing, and these guys made me see the light as well. You may even find a local meetup or club and ask around to find someone that has tuned your vehicle before and absorb info from them. Start with what you drive and go from there. My suggestion is to start learning about engines in and out, learn what each sensor does, and join a message board specific to whatever car you drive, and see if they have a tuning forum. ![]() I hate to make it sound like you shouldn't learn though. For example, you could start cranking up ignition timing because you heard advancing it increases power, then get a ton of KR and wonder why your car runs worse than before, and even worse, you could damaging your engine. Last, you really must know how to read live sensor data and what each sensor does and how they react to certain engine conditions before you start trying to tune an ECU. HPTuners started out with only GM vehicles, but they do have a lot for Ford and Dodge now I believe. I'm sure there are others that are cheaper, but many of them are restricted to a certain group of makes and models. I've only used HPTuners, but this was like $700 when I bought it. You buy a tuning package, it comes with software and an OBD2 interface, and connect your laptop via USB to the OBD port on the car. You are correct however about how they work. The closest you'll probably get to that is like a JET programmer if they make one for your car, and those are questionable at best. Also, IMO there's not really a way to get into just a small bit of tuning, at least safely. I'm really not trying to discourage you, but I really doubt you're going to find any tuning software that's even decent for free or cheap.
