Motec's being wired this week - what should I datalog?

[750hp]

I dropped the motor at the electrician's shop today, which leaves me only a few more days to work out what extra sensors I need to install for datalogging. So far I plan on having:

Oil temp
Oil pressure
Fuel pressure
Fuel pulse width
Fuel pump(s) voltage
Fuel volume through return line???
Air temp before intercooler
Air temp after intercooler
Manifold pressure
Water temp
Throttle position
Ignition timing via crank trigger sensor

I would like to have individual temp sensors in each header pipe, but the sensors are just too expensive to buy eight of them. The car should be making around 850 - 900hp at the flywheel, and the dyno shop's wide band lamda sensors will be fitted only while the motor is on the engine dyno. Motec enable wideband logging for the first 6 hours running time for free. Two wide band sensors along with permanent lambda logging is nearly $1000US on it's own

Have I missed anything? The car will be mainly used on the street, but I'd like to get it on the roadracing tracks and dragstrip around here when I can. I'm using a Motec M800 on a supercharged fuel injected intercooled smallblock running a little over 20lb boost if that's relevant to your answer.

Thanks for your help - I bet I've forgotten something.....
