you have to run windows 98 to use dattlogger and a computer with serial port,I have the software it's called dart ,I have the mapper type monitor my self i can change fuel and ignition in car,also these are getting very rare, I have a spare plug to go into the dionostic, just need to make one up for the other end,can send you pics if needed , you will need the data stream enabled on the chip need to ask stu from msd if it is,or it won't work ,hope this helps also make sure it's to work with l8 not a pectel t6 , if you remove the back I can tell you
