I would get totally butchered by the MOT people if I tried to do something similar
As per above, Paolo Mendes had his fair share of problems with his exhaust system and the lambda reading from the sensor that was supposed to go behind the catalytic converter. With your Omex system, you're not having problems like that
My car has never had an MOT or NCT test.
The 200 cell cat is sitting on the spare exhaust system for the 147 in my garden shed.
Remember,the Omex management system is a stand alone management system.Its completely mapable/remapable to suit any car or any modification to the car or engine itself.
The standard Alfa ecu is ripped out and binned,and the Omex management system is installed/spliced into the wiring loom and you set the engine up from scratch by mapping it on the road while driving (this is called Live Mapping) and then by fine tuning it and doing power runs and fuel setup runs on the dynapacks.
I had to have a complete new wiring loom made up as the car was turboed and alot more gadgets were being added on aswell,so a new/bigger loom was required.This was boring and time consuming to make and set up but vital for the engine to fire up and run properly.
Basicly everytime a modification is done to the car,the Omex management and the chip inside gets another map/test session on the dynapacks so that the engine can function perfectly and at its best with the modification or modifications.
I have no silencers or cats and no lambda sensors in the manifold or under the car.
Thats why the car is loud and also a reason why the car pops and spits the odd flame or 3.
That small lambda/oxygen sensor you can see in the pic of my exhaust is just the AEM sensor that is linked up to the AEM digital guage and the data logger system(this is linked into the Omex ECU) so that the air/fuel mixture can be set,recorded and altered to suit the engine and its performance.
Pic of AEM digital guage setup.The Omex management system sits inside the car,just to the side of the passenger footwell.Nice and warm and dry there.
