Im using the s200.
Acer aspire laptop
Keyspaw 19w usb-> serial converter.
my car is a obd1 p30 ecu.
when i want to connect i get a connection error.
i have used the Keyspawn diagnostics.
and it seems that the second test (incomming) fails.
should i try a different serial calble?
My motor is not in the car right now but that can be the problem right?
connection problems.
