![]() Of the data it receives from the various sensors in and around the engine.Ī file that tells the editing software how to interpret each byte in the binįile. The information the vehicle's computer (which goes by various names: ECM, BCM, ECU, PCM, DME, etc), needs to make sense/use The bin file contains raw binary data imaged from the vehicle's memory itself,Īnd each byte or set of bytes in the file corresponds to a particular function The bin file is the partial or complete image of the calibration information, the code that the computer executes, or both. It is this file that TunerPro manipulates. The filename extension for that file is typically. Once extracted, the information is typically stored on the PC as a single binary file. Just how this is done typically varies by the manufacturer of the vehicle's computer. This flash memory is typically read using a special set of instructions passed to the computer through the diagnostic port. Starting around the mid-90's (depending on make and model), many vehicle computers utilized flash memory to store the calibration and code. TunerPro can directly interface with the BURN1 (Flash & Burn) from. PROM burner must be utilized for burning the new, or modified bin file back Once the chip is read, the file that contains the information from the chipĬan be saved via computer to file (the bin file). Most PROM burners interface with a computer, and The PROM burner is a hardware device that is used to read the Older vehicles tend to have EPROMs or EEPROMs, which can be read with a special piece of hardware called an EPROM or EEPROM programmer (or "burner"). How the binary information is stored in the vehicle plays a role in how the binary information is extracted from the computer. TunerPro can edit binary information from a wide range of makes and model vehicles, and from a wide range of years. The major pieces are explained here.ġ) Obtaining the binary data you wish to editĢ) The binary data itself (a BIN file, etc)ģ) The definition file that deciphers what each byte in the bin means in the "realĥ) The editing software (TunerPro) that can load the binary file and and interactĦ) Uploading the newly edited bin to the vehicle There are a number of components involved in editing binary data with TunerPro.
