whats datalogging and what can datalogging tell me? i will be getting crome ecu and i need to get a socket installed for datalogging but i dont know what that is? does anyone know what datalogging can tell me so on thanks.
The performance characteristics of a car can be monitored through its diagnostic port. Datalogging a car allows one to observe how well the car is running. A datalogger can be used to help tune the car if modifications have been made to the vehicle. The reason it helps is that it logs various parameters in the engine such as ignition timing, injector pulse, RPM, knock/detonation, barometer pressure, temperature, oxygen sensors, and various other sensor data. Using the information that is provided, a user can change the injector pulse width so that the engine is fed more or less fuel, increase or decrease ignition timing, and so forth. Such changes are made to make the car run more reliably or achieve higher performance.
ok thanks. so u think its a good idea to get the datalogging cable install when the chip the ecu? u cant make changes with the datalogging unless u reburn a new chip right?
That is correct. You need to update the chip (the hardware that contains the fuel/ignition map) in order to make changes to how the car runs. You can view the effects of these changes by analyzing data from the datalogger.
I’m not sure if www.PGMFI.org is still down, so here is the backup site. If you have ANY questions about chipping, crome, datalogging, ecu’s hardware, fuel maps, tuning tips, or anything else honda tuning related go read in the ‘library’ or ‘wiki’ on that site.
ok thanks man
