![]() Right now I don't have a method to flash back to the bike, so I will probably purchase the full version of HondaECU to do it unless some ace coder comes along and wants to help try and get the python stuff working. I will have a look at the timing map too but my thoughts at the moment are to leave that alone. You can hopefully see in the picture where the fuelling drops off on the stock map. I think I will up the rev limit a little, and add more fuel above 5500rpm. Not a massive surprise with only 48kb storage to work with. ![]() This is due to strict EPA laws in which limit the manufactures to. While changing these parameters we can improve performance, reliability, and often times unlock any restrictions set by the ECU. There's basically only 2 tables, ignition and fuel. Flashing an ECU is to make a hard change within the stock parameters, unlike a piggyback system which merely tricks the ECU into the changes you make. I was able to load it into TunerPro using the xdf from github, and the tables all look good. For anyone reading this in the future, I used offset 0x4000 and got a 48kb file. I did find an older copy of HondaECU which lets you read but not write when it's unregistered, and was able to read my ECU. I'd be happy to share whatever I find, I think it would be cool to have an open source tool for flashing and some community documentation on how to remap your Grom.Ī friend from another forum did manage to compile the github software I linked, but it didn't work. I guess what I'm really asking is if anyone can help compile the open source HondaECU, or has an old windows.exe version of it? I have a cable to read the ECU with, just need the software. The problem with that is its source code and I can't seem to compile the program for windows, I tried following the instructions but get errors that are beyond my ability. What I did also find is that HondaECU was previously open source, and some of the old versions/branches are still there on GitHub eg There is MCU innovations HondaECU, but it's $150. Such as installing a high performance exhaust, high performance intake system, performance camshaft, ported cylinder head, big bore kits & so on. Our reliable, high quality ECU re-mapping service starts from just £350 +VAT.There are a few tools out there, Hondaflasher ( ) although the page doesn't seem to have a download. It’s also possible to unlock additional features and capabilities of the ECU – for example, on the latest Kawasaki ZX10r we can enable the auto-blip function, adjust RPM limiters, adjust fan temp, and adjust RPM idle, to name just a few. ![]() Its primary purpose is to improve rideability. ![]() The benefits of ECU flashing aren’t necessarily about headline-grabbing power gains but rather achieving a smoother, more responsive power delivery throughout the rev range. Thus overwriting the chip with a new program is known as flashing, re-flashing, or direct ECU mapping. An ECU chip uses ‘flash memory’, a type of solid state software encoding. ![]() There is still a case to be made for taking that path, as a fuel module can be easily removed, returning your bike to a completely stock condition.īut as an alternative it is now possible to directly re-program an ECU chip. Previously the only way to alter these settings was to use a piggy-back fuel module, such as a Power Commander. ECU Flashing is the process of updating the sofware that runs on your bikes ECU. Woolich Racing BMW ECU Flashing products allow you to tune the maps and settings in the BMW ECU. The real-world consequences of these compromises are experienced in things like snatchy throttle pick-up and flat spots at certain points in the rev range factors that directly affect rideability. Excerpts and links may be used, provided that full and clear credit is given to Woolich Racing and with appropriate and specific direction to the original content. Ultimately, this program determines how your engine operates.īut the manufacturer’s program contains a number of compromises and limitations, both for engine reliability and more often to fulfil emissions test and other regulatory requirements at certain RPM values. The ECU is factory pre-programmed to manage a wide range of parameters. All modern engines are controlled by a microprocessor chip the Electronic Control Unit or ECU. ![]()
