Ecu speed

Not sure if this comes up in the Engine section but I'm looking at using dashcommand with a wifi obd adapter.

Now i gather that the refresh rate and lag depends massively on the speed of the ecu, and that Toyota Ecu's are some of the fastest, but does anyone know how much lag I'm likely to get?

I'll be using an Iphone 4, displayed on the Pioneer Appradio, via Obd Wifi.

Does anyone else have experience of any of the above?

IIRC it uses ISO9141-2 protocol... thats all i can say. I have tested Torque and HobDrive software on Android and Windows mobile with cheap ebay bluetooth elm327 adapter and they both ar kinda slow... not sure if its ecu's or adapters fault, sorry...

Most likely the OBD adaptor. The scantool.net and PLX devices can read over 60 PIDs per second. Other adaptors are slower.

That's what i was get at, I've tried it with a bluetooth adapter and the refresh rate was fairly slow, but I didn't know if it was the adapter or the ecu.

I'm loathed to chuck more money at a wifi adapter if it's still gonna be god slow.

I'll be using an iphone 4 and dash command.
