How do you communicate with a Motec m48?
I bought a X group N Rally car with motec m48 ecu in the stock housing. I open the case and saw the below written on the circuit.
Motec Europe Ltd
Mits Evo/0A-797
Soldside Issuse A
Emp 0375 990
05971

There is no usb port on the ecu so my question is how do I connect/communicate using a Laptop with the ecu?
I NEED HELP

 

you have to have the special motec com cable. the connector on ecu is about half the size of USB port

 

I have pictures but i dont know how to upload them

 

create a photobucket account.
upload your pics to that account.
once you have uploaded them, you can link them using the "img" code

 

or even easier, just use image shack. you dont even have to register at all .

I found out that a MAX232 chip can be used to communicate
my question is what pins on the ecu should i use?

thats interesting. looks nothing like the motec PNP I have here. the one have have is based off the m800 board. the setup you have looks professional. like it was made at motec. may have been custom ordered for someone used to using the m48. you should send those pics to motec. they are always very helpful. obviously it must communicate through some wiring off main plug. but thats just a guess.

 

I know its not a m800 board it is confirmed to be m48. I found out what is needed which is a mx232 converter , what i need now the the pinout

 

now i want to know how to build the pci cable using a max232 chip

 

on the early plug in, the comm is through either the diagnostics plug or added to the harness

 

I found out that it is added to the harness but i dont know which plug and wire
i bought the serial to max232 converter, i just need the wires to connect it to

 

helppppppppppppp!!!!!!!!!!!!
