Defi sensors linearisation

[jura11]

Hi guys

Not sure guys if someone don't have Defi pressure sensor linearisation?
We are wired today Defi Oil and fuel pressure sensor linearisation,we are used only white signal wire and separate black and red we are wired to cigarette lighter or do we should wired this to the Syvecs ?

Please guys if you do have please if you could post them

Thanks,Jura

I've just realize when I post this,what we are done(I've re-read old emails from Tim,when we are bought the sensors first time and then I realize what we are done)
I'm bit mad on myself,just due we shouldn't use 12v for powering the sensor,there is for reason 5v
But sensor survived this and reads like should
But still if you guys have Defi sensors linearisation I would be very appreciated

Thanks,Jura

Handiest way is get a Mityvac ( one that lets you apply pressure too ) or a compressor/regulator and apply pressure to the sensor and monitor voltage on the ecu.

That way you know for sure it's calibrated correctly.

Can you share the defi oil pressure linearisation?

So are you taking the signal feed from your defi sensor and plugging it into the syvecs for the reading ???
Can you share what colour wire you have used for the signal to syvecs please
