The invention discloses a method and 
system for collecting and 
processing an electronic injection 
signal of a vehicle, and the method comprises the following specific steps that 1) a remote collection device transmits collection parameter configuration information; 2) a vehicle-mounted terminal receives the collection parameter configuration information, converts the collection parameter configuration information into CPP protocol data, configures an electronic injection 
signal collection parameter of a vehicle ECU through a 
CAN bus, then obtains an electronic injection 
signal, transmitted by the vehicle ECU, in a CPP protocol format, and then transmits the electronic injection signal to the remote collection device after conversion and 
processing; 3) the remote collection device receives the electronic injection signal, deblocks the electronic injection signal according to an object relation mapping table, carries out the preprocessing of the deblocked signal data, and then stores the data. According to the invention, CAN-
bus drive and CCP communication 
protocol stack are separated from conventional electronic injection data collection 
software, thereby independently forming the vehicle-mounted terminal with a function of 
wireless communication. Moreover, an on-site / remote collection device is combined, and a function of on-site collection is considered, thereby achieving the function of remote data collection, and greatly improving the development and testing efficiency of the whole vehicle.
