Message	I am thinking along the lines of the stock pressure transducer which is probably 0-5V with an 8bit A/D converter. Nothing special but say it has a range of 0-150psi we still have pretty good resolution of around 1/2 psi. I can't see an application on our cars for more than 8bits. Accelerometers I don't know anything about but a quick search shows they are more expensive at around $200+. The reason why I am so interested in all this is because some tuning software (NIStune) interfaces with a cheap ($30) 8bit USB DAQ converter so I was wondering what the disadvantages of this compared to an expensive setup are (The PC is an expensive piece of machinery too I guess). RPM and Oil Pressure could be monitored by the consult interface so only the Accelerometer is needed.

He road races. (n/m) - AZHeat 18:20:52 02/11/08 how can he test it without datalogging his oil pressure? - aliaZ 18:33:39 02/11/08 How expensive is the hardware for that? (n/m) - AZHeat 18:35:13 02/11/08 Ask someone who designs oil pans... they'd probably know. (n/m) - PennStateZ (VA) 18:40:24 02/11/08 Unless SZ has one , I don't think they are going to - AZHeat 18:42:24 02/11/08 Can't a not so expensive consult setup log oil pressure? - Bezza 19:21:49 02/11/08 Zing!
