The first step is to identify what kind of cable you have and what its board looks like. the first two things i think we should work on are below: PM or comment info that should be included in thread. HOW YOU CAN HELP AND CONTRIBUTE - Use the PDF and report info about your cable. MCP2551 - CAN Transceiver converts signals to/from the bus and the controller so they are suitable for both MCP2515 - CAN controller implements the actual logic of the CAN protocol reading in VCDS threads leads me to believe that if the ft232 is the RL type, this ATF chip is usually present. Atmel Studio 7 can interface with the chip too I think.ĪTF16V8B - another mircrocontroller by Atmel. Or An Arduino can be programmed to ISP-Arduino and the pin connections made to Atmega for programing or reading eeprom. Can be programmed with FTprogĪTmega162 – Microcontroller. Investigate 64bit vs 32bit operating system myths and if it even matters anymore (seems like guys have windows 10 64bit working just fine)įT232RL – communication between USB and other chips on the board, senses ignition and battery for INPA. Investigate if poor soldering or board construction is what the main issue is (no discussion yet) Investigate possibility of DIY alternative interface (that can add functionality ie datalog to SD card, display DME info via iBus, drop tune file on SD card and program with one press of a button?) Investigate what other chips/microcontrollers are on board, communication, and testing
Investigate how many different board designs/what makes them different Some cannot switch between K and D CAN network speed ( if it was advertised as DCAN compatible). Some do not have any connectivity to vehicle (obd2 connector, Pin 7 + 8, bad echobytes, cant connect in boot mode)
Some don't install properly (ftdi chip, driver, usb cable quality)
the cheap cables fail in all sorts of ways.
The alternative is the $100 cable from one stop electronics which is very high quality and proven to work. Most of them can be purchased on ebay and amazon from 5$-30$ with hit or miss results. I would like to iron out the differences among the K+D CAN main boards that are shipping with these Chinese cables. there have been lots of discussion in the tuning thread or the boot mode thread. I ask anyone who is having issues with their devices, or has a device confirmed to work, please contribute some information to any section or PM suggestions.
