Powerfc Djetro... How Much Boost Can Read The Stock Maps?

[GreeceS13]

How much boost can read the stock maps?

I know that the stock scalling is for 26psi...

If I rescale it can I use it for more?

We just ran into this problem. The map sensor only reads to 1.85 bar. I think AEM makes one that will read to 2.5 bar.

[paulr33]

as per the documentation, the djetor kit from memory ships with a 2 bar map sensor

this does not mean it will read 2 bar boost. its far from that, its actually 2 bar pressure, so vacuum and positive pressure

youll find the stock map sensor won't go past 1.3 bar (again from memory, the documentation states this) because its 1 bar negative, and 1 bar positive

so a 3 bar map sensor is probably what you need

They must have changed the sensors, my last five or six D-jetro's are all scaled to read to 2bar gauge pressure and they will all run only to load cell 20 when over 1.9bar.

That's been my experience as well

So untill we run 2bar the powerfc still reads the cell untill at 1.85?

I have rescaled the map for 2.1bar(31psi) instead 1.6(26psi) that is the stock scalling.

So the powerfc will read untill the cells for 1.85bar?

[Cjmartz2k]

The 1.85 was just what my tuner said he ran out of sensor at on his and mine. 1.85-1.9 same same. He's getting a 3.5 bar aem map sensor (1 bar vacuum, 2.5 bar boost) and rescaling. I don't think rescaling is going to do any good if the sensor itself is pegged.

my d-jetro was hitting cell 20 at around 1.4-1.5 bar boost, i didnt care... more BOOOOST

im not very famliar with all this stuff but are u guys saying a d jetro pfc wont be able to tune a car for 2bar of boost?

im running a race prepped head with a gt35r and was hoping for somewhat 25-30psi of boost.

this wont happen with a d jetro?

[skylinekid]

so wat everyone is saying is the stock sensors will not read past 1.3 bar?????? im a lil confused afta the first things ive read?

I'm not sure where that comes from? the ones I've seen measure a small amount of vacuum and will read to almost 2 bar of positive pressure. ie atmosphere plus 1.8-1.9 bar of boost. I can double check this but I'm fairly certain the ones I've played with read to near enough to 2 bar positive pressure.

also the djetro does not ship with any map sensor/s, you have to buy it/them separately. you also need to buy nipple/s and the harnesses. none of that stuff is included if you just order the Djetro power FC.

I had a D-jetro before.

It was tuned to 1.7 bar of boost with occasional spike up to 1.8-1.9.

AF ratio was very stable.

thats probably cause the scaling wasnt changed.
