==Porsche 928 LH Replacement Revisoin 2 Build Pge== [[Porsche 928 LH Replacement ECU|Back to Project Page]] [[Projects|Back to All Projects Page]] [[Main Page|Back to Main Page]] The discussion forum can be found at [http://forums.rennlist.com/rennforums/928-forum/602152-plug-in-lh-replacement.html Rennlist] ---- __TOC__ ==To Do list == Here is where I list all the mistakes I need to fix and the optimisations that needs to be done. This will focus primarily on the hardware side of the board because the software will in the end be 99% the same as the prototype version. I will mark what is done as I complete it. *Replace LM317 with LM7809 for intermediate voltage level *Fix power supply to op-amps *Add buffering to analog input signals *Add more filtering to input analog signals *Use a divide by 15 * multiply by 3.3 to ensure the input analog signal at CPU pin does not exceed 3.3V *Fix USB power line *Replace USB connector *Make board smaller *Add 25-pin connector support *Add aftermarket connector support *Add more diagnostic LEDs *Remove serial lines *Add extra digital and analog inputs for engine mods *Add I2C/SPI interface for future expansion *Add battery voltage analog line *Remove external EEPROM lines *Add header for bootloader *Improve Silkscreen labels *Optimise layout for faster component placing *Add pull-up resistors to TTL signals (EZK Load and Warning Light) *Fix protection diodes *Add MAF-Burn function at engine shutdown *Add test-points *Add mounting holes
