I pulled a map sensor from a 300 twin turbo in a scrappy and I was wondering what bar it is?

 

Do they run at 2bar, or 2.5bar?

 

The only info on the sensor is the number "1108"

 

Thanks in advance

no map sensor fitted to a Z32, guess you may have removed the boost gauge sensor.

standard the 300zx runs an air flow meter

LOL, I thought they ran AFM (plus I could see the AFM) but found what looks like a map sensor.

 

must have been the sensor for the boost guage..

 

Thanks for the reply

apart from the map sensor for the boost gauge, serie 3 twinturbos have another map sensor, under the nose panel.

Really old thread granted but I'm struggling to find any MAP sensor answers either here or on google :headvswal

 

there are a few references in old posts to 'stock' MAP sensors (they're not referring to the MAF) but an actual MAP sensor??

 

any ideas if there are actually any MAP sensors/connectors etc fitted as standard to later gen zeds?

There isn't mate, the only 'MAP' sensor is the sender for the stock boost gauge, all generations used a MAF...

get yourself on the aem forum, your answer are there

I've tried that mate and the answer that I found was that the AEM MAP sensor uses pin #35

but the ECU pin out table shows pin #35 as fuel pump voltage control

I'm happy as to where the sensor taps into but not where you're supposed to wire it into?

I'd use this as the setup guide

and this for the pinout

yes, it's for the fuel pump voltage control on a stock ecu, but onthe AEM it's not used, hence available for the MAP input

Cheers mate, that's exactly what I've been looking for :thumbup1:

Next question, does the EMS actually 'have to' use the supplied Bosch sensor/s or will it just run normally on stock O2 sensors as a temporary measure?

I know that the MAP sensor can screw into the plenum but as a temprary fix, is it possible to run the MAP sensor off the balance bar using a length of 6mm vacuum hose and the vacuum hose attachment screwed to the sensor?

yes, vac hose is fine and is how I've had mine fitted

Excellent, cheers mate

Next question, AEM make reference to the possibility of having to replace the CAS Disc...

 

anyone done this yet?

depends on the system used .. but yes .. the emerald system u need to as well
