Does anyone know if the baro or scip sensors are 2 bar. or is it just the map sensor.
I am going to use one to control my watermeth on my trans am and was wondering which one to use.
Thanks.C

 

your TA wont have a SCIP (supercharger inlet pressure)

and a baro (barometric presser sensor) measures just atmospheric pressure changes.

is your TA boosted? if so, use map

if not, set it off TPS.

 

I am going to be running the sts turbo kit. I still have my progressive devils own water meth kit off the Cobalt and it uses the map sensor. I sold my old intake and left the sensor in. I still have the baro sensor so That is why I was wondering if it was 2 bar also.

 

I think they are both 2 bar sensors, but they do have different part numbers. The IAT2\MAP sensor in the intake manifold is a 2.5 bar sensor.

 

I noticed that the iat 2 was in the intake press sensor but didn't know if the baro sensor was 2 bar also it doesn't say in the parts catalogue

 

an IAT sensor DOES NOT measure pressure, it has no "BAR" rateing.

same with the baro sensor, thats for atmospheric pressure only.

your MAP sensor is the key, 1 bar is required to read normal, day to day pressures. any boost amount requires the sensor to be set up to read above atmospheric.

a normal NA car will not have such a feature from the factory.

 

I think he understands an IAT DOES NOT read pressure, but the SS does have a 2 in one MAP sensor.

 

yup.

 

Exactly^^ I just want something to control the water meth not feed the pcm. I guess I'll have to take a voltage reading off the baro and see if it is 2 bar.

 

it reads atmospheric pressure, thus its a 1 bar.
