Logging Boost

[Crans]

Guys just need a little help logging boost.

I have a Techedge 2J1 Controller and an Apexi AVC-R I have wired the middle pin from the Apexi map sensor to the AUX IN 1 port on the WB Controller.

The Techedge software, as well as Nistune software are reporting voltage values of 0.00 - 0.02 <- I think this value is ground float.

Have I connected the correct pin from the Map sensor?

Any one have a voltage to pressure table for this map sensor?

Do I need to install any resistors/capacitors to the wiring for this to work properly?

ill my voltage of BOST when i head home tonight at idle, which is around -500mmhg

Cheers,

It wold be easy to build the table if i had a voltage generator, but none of my embedded boards had DAC's.

Got the multimeter out today and the correct wire to tap is the white wire.

so...can you post up a voltage table

[Crans]

Havn't got a voltage table done quite yet, working on it all i have now is nistune reading in mv from my techedge.

I have searched the net high and low for a voltage table that is complete and actually works but nothing so far.

I need something that a can set to output any voltage i choose between 0 - 5v and i'll have it done in no time

normally just use a compressor, good regulator and a pressure gauge to confirm, the use multimeter to record voltages at different pressures.
