well, ive finished soldering the ecu connectors and plugged the motec in. the car cranks but i cannot communicate with the ecu via the RS232 cable. no matter what i try it just ignores me.

bastard.

back to the drawing board tomorrow with crocodile clips and soldering iron. lets just hope this isnt a duff ecu...

Try to perservere Andy. These bloody cars always try and trip you up, regardless it seems.

Just keep thinking of the spanking you can give the car when it is done. Will make it all worth while

andy what motec is it theres a couple of ways of connecting for rs232...

gary, its an M4 and ive checked the wiring on the PCB itself (RS232 port wired directly off it). the guy i bought it off said it needs the older M4 software to communicate so i will be trying that tomorrow (downloaded about 8 old versions to try).

the serial port is definitely connected 100% as per manual specs...

its alive!
the ecu that is, not the car as a whole. there must be a problem in the car wiring as ive hooked the ecu up to a battery and its working fine.

i wasnt sure of this when i bought it, but its the Pro version with all the advanced tuning features enabled too...things like:-

higher resolution tables
wideband lambda control
launch and traction control
anti lag

512k of data logging

and probably other stuff too
