Good engine monitor for iPad?

Just wondering if anyone had any suggestions for a basic iPad app and hardware for basic engine monitoring. I don't need anything fancy, but I'm thinking maybe a Bluetooth odbii reader and an app that does:

Real time tachometer
Mpg calculator
Engine code readouts

Bonus if it has extra features for Diesel engines. I'm not looking to chip or tune my engine, just monitor on longer trips.

Dash command is the one I hear the most about. The iPod/pad uses either a cable or a wifi adaptor for the obd2 adaptor. Apple won't let us use Bluetooth for anything other than headsets.

I have an android tablet and use Torque with an Elm327 adaptor and it works well. I wish it had more diesel specific meters though...

This isn't for iPads, but it's pretty much the standard software that diesel tuners use:

Scan Tool

At least on Fords (the package I have), it monitors over 500 things from multiple systems. It can do real-time monitoring, data logging, readout multiple ways, scan codes, reset codes, etc. Pretty much everything a $4000 Snapon scanner or the actual Ford scanner will do.

They have a package for every major vehicle brand.
