he is using the ostrich to burn chips.
i think he needs to try flipping the tx/rx lines and see if that helps any. the ecu is not responding at all when the bytes are sent so either the rx/tx is messed up, the lines aren't inverted, or the ftdi cable is bad.
thats the same cable i use. i'll check my connections when i get home and let you know how i have them set up.
rob - isn't there some quirk with the lm and inverting the signals depending on how you hook up to the ecu?

FT232RL -
Orange cable (TX)-> Green wire on the SCI connector
Yellow cable (RX)-> Pink wire on the SCI connector
Black cable (GND)-> Black wire on SCI connector
and further down per rob L regarding inverting signals for the lm--
"I thought this (NOT inverting signals) was only true if you were wiring in the cable/adapter directly to the MCU. If you plug it into the SCI port like on the SMEC and SBEC, you still need to invert the logic levels, correct?"
and risen responded that rob was correct.
