[AEM 3.5bar Map Sensor - Calibration Table Help]

Hi,

I´m using an AEM 3.5bar Map Sensor in a Skyline R34 GTT (G4 Plug in).

The correct AEM constructions are beginning:

Volt     PSI

0.5     -14.7

0.75   -11.575

1          -8.5

....and so on.

But in the calibration table I´ve set:

Input Units = Volts

Output Units = PSI

Output Table Start = 0 PSI  (the Problem!)

Output Table Increments = 2

--

The problem: how can I set the 'vacuum / negative PSI' like -14.7 at 0.5 Volt? The software only allows to start with 0 - not with any vacuum / negative PSI...

[AEM 3.5bar Map Sensor - G4 RB25DET R34 GTT Skyline]

Hello,

I´ve got a problem with my new G4, its the first time I use this ECU - I tried to find a solution in this forum and the Help...

I want to use a AEM 3.5bar Map Sensor - the help says I should select one of the listes sensors, which could match - so I select the Standard 4 bar - the BAR is about 107 kPa.

When I try now the sensor calibration, it comes the failure:

'MAP Sensor Calibration command failed: Current MAP <5kpa or > 5kPa of baro reading'

I tried also all other listed Map sensors, but the 4 bar matches best with BAR 107 kPa.

What can I do? The help says there is a Cal 1-3 and Cal 4-6 custom Sensor - but I can´t find in the PCLink a table where I can set any custom linear or tabled calibations. So what can I do to use the AEM 3.5bar Map Sensor?

Thanks!!
Daniel
