Chris Wilson Posted July 12, 2011 Share Posted July 12, 2011 I am now selling brand new genuine GM 3 bar MAP sensors for £82 plus VAT and P&P. I use these for aftermarket ecu's as the data on them is available, and many have pre compiled tables for them, plus I use them for data logging air filter / intake restrictions, pressure drops across IC's, and exhaust back pressure pre and post turbo(s). Motec want £130 plus VAT.... To data log you need either an ecu like a Syvecs that can log data, or a small standalone logger. Someone handy could just use an small industrial logger if all they wanted was to monitor pressures from these sensors. I may look into this. If you have a 12 volt or PC run oscilloscope you can read the pressure from that. It's the proper way to see just HOW restrictive things are, and choose turbine housing sizes.
