data loggers

hello i have a 2009 dodge ram 2500. can anyone tell me what data logger they are using. i have a diagnostic software that says it does data logging. but i havent used it. it is called touchscan with the fca add on. my vehicle is currently down due to mechanical issues. that i working on. rear seal leaking. anyways i am taking this time to learn about diesel tuning. and was wanting info on what everyone uses thanks

EFILive and HPTuners are the best dataloggers for this platform. EFILive's EDA (CSP5) probably edges out HPT if we're splitting hairs.
