Nistune Forums

Hi All,

Right I have nistune up and running. I have just purchased an 8 Channel USB data acquisition board. This will enable me to data log 8 extra channel.

I'm going to be using it for my AEM wideband 0-5v output (As logging it via serial is proving very temperamental....)

I always want to log boost. So my question is this....

Does anyone know of any suitable 2 bar or similar map sensors. However the caveat is that i need the 0-5V look up table so that I can make sense of the data.

So recommendations please.

Thanks for you help.

most AEM map sensors come with a conversion diagram/table (Voltage vs. pressure/vacuum), so you can use that.

Hi Eric
do You by any chance knows table fro Greddy MAP sensor?

Freescale make a wide range of sensors that cover the automotive range. I use the MPX4250GP - it goes to 36psi.

a quick google revealed this conversion table for the Greddy Emanage map-sensor

psi = (14.508*voltage)-21.762

not sure if it's correct, as I never used any Greddy map sensors.

Thanks Eric, obviously I did enter wrong tags on google
