Yes, it is the best way to stay "agnostic". Using parameters 0 for AT SP command let the charge to the ELM to fid the protocol automaticaly. The automatic research take for time for the initialization. I insist only on the initialization. I guess it's advice to wait 14s before sent the first OBD command.Quote:
Is it safe to assume that this command will find the fastest protocol a vehicle is capable of?
A vehicule (ECU) is design with a protocol and can't support severals. Older vehicule (non CAN) are slower that's all!Quote:
