There's a lot of info I no longer get (nor need) on mine such as timing & MAF, O2, etc. anything that related to EFI but I'm happy to get real engine temps & volts without having to add gauges & sensors. I also used it to set my TPS and it will show if my TPS has an issue.
Other big advantage for me is that I can still do full auto trans diagnostics via Ecutalk.
