Is there a difference between Computer Control Module from beretta gtz 91g age and beretta gtz 93g?
I have swap engines from beretta gtz 93g age to 91g but the CCM has remain form older model.

And one Stupid question:

Where is located Computer Control Module in beretta GTZ??

I have been looking that CCM but no luck

sorry people my grammar is bad )

You will have to compare Service IDs.  I think they are different between those years.  They changed the AC control and Ignition Control.

The ECM is located in the passengers kick panel.  Down by floor board on the far right.

thanks man, problem is that my car is gain a lot of fuel and I lose power(not when engine is cold) , I have change Fuel Injectors,O2 sensor(lambda probe) but problem remains! The only thing that I havent change is CCM.

have you some ideas?? maybe some sensors?

Coolant Temperature sensor and Intake Air Temperature.  If you have a scanner you can see the reported temperatures from the ECM data stream.

Check the fuel pressure regulator too, but that is not likely to be the problem since it only happens when warmed up.

Do you have an exhaust leak before the oxygen sensor?

hm no i have not, exhaust pipe is new,60mm,one cat,one middle pot and copy of apexi N1, now I have to find those 2 sensors Can it be the ECM? becaouse it is from older model

Computer Control Module

2.3 liter..........'90-91...1619-8267 mine CCM
                      92-93...1614-6450 complete Engine is from 93g

If the ignition control module (under the coil cover) is from a 93 then yes there is a problem.  You need all the ignition components to be from the 90 GTZ so that they match the computer.  I would suggest that the wiring harness on the engine and to the firewall from the 90 GTZ.

So to review.  You must use the electronic ignition parts from the 90 with the 90 ECM and 93 electronic ignition parts with the 93 ECM.

I didn't even know you could make the engine run with a mixed year system from 90 and 93.  Perhaps the export market cars are a little different?

The coolant sensor is located near the thermostat and the IAT is on the top of the intake manifold. (2 wires)  There is also a temperature sensor near the thermostat housing for the dash temperature gauge.


I have a feeling if you just swap the ignition components from your old engine onto your new 93 engine you will solve all of your problems.

wood a plugged convertta make exhaust cherry red ?
