They are definitely changed with the SS kit, though can't remember the codes off hand.

Original are
0281002844
and
0261230042

They are used on lots of different cars (above are used on Vauxhall, SAAB, FIAT, ALFA, LANCIA, PORSCHE).

I'll have a look tonight.
I got 3 sensors back when I got the SS kit fitted

1 x 0261230042 (I think that one was in the metal intake tube).

2 x 0281002844

According to what I read on another FIAT Forum, the MAP sensors on GPs fail quite often.

Thanks for the info and taking the time to have a look, much appreciated 

Managed to have a look at the official contents list for the SS kit.  It does not give full part details, all it states is that there are 2 pressure sensors supplied in the kit but does not give any part numbers.

Spoke to Fiat customer services, they haven't got a clue what the part numbers are and nobody got back to me.

Spoke to Abarth technician at a certain dealers yesterday, he absolutely assures me that the inlet manifold sensor is not changed when the SS kit is fitted, only the boost pressure sensor in the black inlet pipe is changed according to him.

Reassuring to know all these trained experts know their stuff.  Don't know why it's so hard to get an answer to what is a pretty basic question.

 Makes you laugh to think that they won't let Fiat garages do Abarth warranty work because they have not been 'specially trained' 

Thanks again, at least you know your stuff 

I'm sure I got 3 sensors back after having the ss kit fitted 

AAAAAAHHHHH

What boost are you running?

If 0.5bar then the sensor 0261230042 is fine as it reads 20-250kPa.

However if you're running 1.0bar then you'd need the sensor 0281002437 as it covers 20-300kPa.
These are T-MAP sensors (i.e. measure temperature and pressure in one sensor).

Sensors 0281002844 and 0281002931 are just MAP sensors (i.e. only measure pressure).

You definitely need to change the sensor then as you're taking the current one over it's design limits.

Shame you missed this one http://www.ebay.co.uk/itm/Genuine-Bosch-3bar-TMAP-sensor-0281002437-/190555860702?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2c5e03aede as that's rather cheap.

What boost are you running?

I've got a seperate boost gauge straight off inlet manifold and i'm running a peak boost of 1.8 bar and a constant boost of 1.65 bar . . . . maybe that's what's killing my sensors   

I thought the boost was raised from 1.3 bar in the standard to 1.5 bar with the Garrett turbo (ss kit).  I'm surprised you're running 1.8 bar.
What bhp figure are you getting?  Mine is 179bhp

If 1.8 bar is correct then perhaps you should look at a different sensor or ask the technicians why you're getting so much boost.  Green text is the current SS sensor, blue is the next range up.


Bosch sensor info:
Applications
This sensor is used to measure the
absolute intake-manifold pressure. On the
version with integral temperature sensor,
the temperature of the drawn-in air flow is
also measured.
Design and function
The piezoresistive pressure-sensor element
and suitable electronic circuitry for signalamplification and temperature compensation are mounted on a silicon chip. The
measured pressure is applied from above
to the diaphragm’s active surface. A
reference vacuum is enclosed between the
rear side and the glass base. Thanks to a
special coating, both pressure sensor and
temperature sensor are insensitive to the
gases and liquids which are present in the
intake manifold.
Installation information
The sensor is designed for mounting on a
horizontal surface of the vehicle’s intake
manifold. The pressure fitting together with
the temperature sensor extend into the
manifold and are sealed-off to atmosphere
by O-rings. By correct mounting in the
vehicle (pressure-monitoring point on the
top at the intake manifold, pressure fitting
pointing downwards etc.) it is to be ensured that condensate does not collect in
the pressure cell.
P High accuracy.
P EMC protection better than
100 V m–1
.
P Temperature-compensated.
P Version with additional integral temperature sensor.
