I read in some forums that i can try run my vehicle (catalyzed), with empty catalyc converter and connect non catalized ecu, because my catalyzed ecu with empy catalyc converter gives a big CO2 index, and no pass the vehicle inspection (they measure CO2 index).Use your original manifolds on the new engine.
D16z5 = DOHC zc with o2 and cat
D16a9 = DOHC zc without o2 and cat
They also have a different flyweel so you might have to change your pressureplate or reuse your old flyweel. Your diskplate goes with your tranny. I believe it was 21 teeth for the z5 and 20 teeth for the a9.
Your ECU will complain if it can't find an o2 sensor. So use your old exaust manifold.
You can use the new intake manifold, but i'm not sure if it's easier than using your old one.
Thanks a lot for your time!!the PM7 ECU for the cat equipped cars uses the O2 sensor reading to control the fuel mixture for CO - the PM7 ECU for the cars without a cat uses the IMA sensor to control the fuel mixture for CO - to use the PM7 for cars without a cat, you could install an IMA sensor and get rid of the cat - you would need to wire up the IMA sensor, which would consist of switching a couple of wires at the ECU and splicing into a couple of others
the O2 sensor on the cat equipped ECU has a white wire which goes to ECU pin C16 - on these cars the ignition timing connector has a brown wire which goes to ECU pin B20
the IMA sensor on the cars without cat has 3 wires - yellow/white which is the 5 volt reference signal, green/white which is the ground and brown which goes to ECU pin B20 - on these cars the ignition timing connector has a brown wire which goes to ECU pin C16
to use the non-cat ECU, install the IMA sensor and connect the wires as follows:
splice yellow/white wire into yellow/white wire at ECU pin C13
splice green/white wire into green/white wire at ECU pin C12
cut brown wire at ECU pin B20 and connect brown wire from IMA sensor to the portion of the wire remaining in the ECU at pin B20
cut white wire at ECU pin C16 and connect the brown wire remaining in the harness, when you cut it at the step above, to the portion of the white wire remaining in the ECU at pin C16
leave the white wire remaining in the harness not connected - it went to the O2 sensor which you can eliminate or just leave the sensor in the hole in the exhaust manifold as a plug
you could remove the O2 sensor from the manifold and just install a plug in the hole
this is where the IMA sensor is located on the non-cat cars (the IMA sensor has an adjusting screw for adjusting for the CO reading)
if you want to control the Air/Fuel ratio with the Innovate or AEM controller, you need to be using the ECU that monitors and controls the A/F via the O2 sensor - the ECU that does not use the O2 sensor won't work for this function - whether you have a cat or not is immaterialThe last question, if i want to use innovate Gauge with wideband or AEM uego, that have analog output, i can use this with my ecu without modify cables (already have o2 sensor) without cat with any problem??
Connect the analog output of uego/innovate to White (O2 sensor of ecu) cable?
