RS232 IR Gas Analyser.

[The Punisher]

You could post that PDF in the incoming, at the diy-efi site.
If it already has an rs232 output then it must already do alot of the work 
for you as far as sensor driving/reading and possibly interpolation. It 
sounds like it would be very simple to make a uC powered display with it.
For $750 I am assuming that is for the sensor and rs232 interface, can you 
purchase the sensor alone?
Also, since this would be in the exhause system what happens whn the windows 
that the IR emitter and reciever get a coating of soot on them? or am I 
missing something here ?
