The FreeScale MPC5554 processor wil give it all the connections or features you could probably ever want, but will be use a DIY assembled Input/Output board so you only need to purchase and install the components you actually need. This design will allow 5554 to be assembled for as little as $750 for a basic application and under $1000 with all features installed while out performing commercial E… text/html 2009-09-02T15:21:55+00:00 http://wiki.freeems.org/doku.php?id=design_inputs&rev=1251904915&do=diff General requirements: 1) Easy setup. 2) Reliable 3) Finished product appearance when installed. 4) The smallest foot print possible 5) Automotive grade components 6) Water tight case 7) Surface mount components preferred 8) CPC or connector(s) 9) On board memory for logging….say enough for 1 minute.

However, read the below for more details and get involved. Right now we are waiting for software to develop to the point where we can make the final attachments of the circuits to the CPU pins. Easy work compared to what has been designed so far. text/html 2008-11-03T01:37:23+00:00 http://wiki.freeems.org/doku.php?id=freeems_typeb&rev=1225676243&do=diff General Spec This version of FreeEMS is intended as snap in (or near snap in) replacement for BMW ECU. 6 cyl sequential fuel and spark 2 MAP sensors one bametric, 2nd intake 3 general purpose ouputs for fuel pump, ect 2 RPM inputs for both VR and hall sensors schematic done with KICAD PCB layout done in PAD's General Layout * remember to fill in the blanks text/html 2008-12-30T10:48:18+00:00 http://wiki.freeems.org/doku.php?id=git-howto&rev=1230634098&do=diff GIT How To Summary Here's a brief overview of the steps detailed below for using git with FreeEMS * Create SSH connection using agent * sign up for a free account with github * fork off a branch of the code * clone the project you forked off, getting your self a local copy * study and make changes * push your changes back up to github to allow others to see text/html 2009-09-02T15:23:20+00:00 http://wiki.freeems.org/doku.php?id=input-ouput_specifications&rev=1251905000&do=diff 5554 Input/Output Specifications Input- physical Number Value Comments MAP 2 0-5 Standard MAP sensor TSP 1 0-5V Standard pot type TPS Coolant Temp 1 0-5V Thermistor type Temp sensor Air Temp 1 0-5V Thermistor type Temp sensor Optional 4 0-5V Unspecified analog inputs reluctor … text/html 2010-06-03T21:45:06+00:00 http://wiki.freeems.org/doku.php?id=start&rev=1275601506&do=diff Welcome to the FreeEMS wiki, where free means freedom, and open source means open for anyone to read. FreeEMS is a free Engine Management System. It includes both software and hardware designs for the experimental engine. Have you ever thought that an engine could run better than when it was manufactured, but haven't been able to make a prototype because it was too large of a task for you to accomplish? Or perhaps you want to do something special at the race track or on a closed stage.
