It says...

 

MAGNUM O2 Sensor Simulator is an indispensable tuning device on engines where catalytic converter was removed or exhaust was modified (headers). Decatting indicates polluted exhaust gas to the ECU, therefore check engine light will pop up, resulting ECU limp mode and reduced performance at the wheels. O2 Sensor Simulator is a plug-in replacement wired up to post oxygen sensor harness. It supplies the ECU with perfect voltage signal and tricks the ECU thinking the emission is normal. With MAGNUM O2 Sensor Simulator you will get rid of suffering O2 sensor's catalyst efficiency error code, accordingly you can restore the lost power resulted by ECU safe mode due to CEL, besides our O2 Sensor Simulator is fully adjustable, allowing the operator to adjust the most powerful, advanced Air Fuel Ratio is yet accepted by the ECU. You can completely disconnect or remove the stock oxygen / o2 sensor and replace it for O2 Sensor Simulator.

 

These are on ebay currently at about £40 squids + P&P

Let me know your thoughts?

All the faults and troubles mentioned in the text applies to cars with OB2 diagnostic not applicable to zeds.

...stopped me making a fool of myself (again)!! :bow:

I,ve had my car now for 4 years and it,s never had any working o2 sensors in it , i de-catted and fitted a pair and it ran ok but hunted up and down on tickover to the point of stalling so i took them out and run correctly so i still havn,t got any fitted and it runs a treat , i,ve had sooo many people say that it shouldn,t even run properly but it does :dance::dance:

When you took them out, what did you put in their place bud?

Hi Jeff, :bow:

I got a note from Zsolt Toldy in Tech Support at Magnum Autotuning Engineering - who are selling these on ebay as above and they have responded as follows:

 

"The fitment doesn’t depend on OBD category I don’t know how you mean the description refers to this factor. Our evaluation does work on all engines fitted with zirconia oxygen sensor from 1983 through 2009. It cures every catalyst efficiency error code resulted by decatting or exhaust modification and replace the factory oxygen sensor."

 

Is the only way to verify this for me to/someone to try them? :cool:

 

Or can anyone offer alternative advice based on experience?

 

Any help appreciated.

Ah right,

 

OB1 = On board Diagnaostic. ( Most Nissan 300zx up to N. reg )

 

Low level 2 self learn input system but read only no seperate EMFL ( engine management fault light ) mean the system is unable to react externally to codes, faulty signals or faulty sensors other than to compensate when the rogue signal or sensor is wrong but still in range.

 

 

OB2 = On board Diagnaostic (N reg on, 16bit ecu)

 

High level 1 self learn input /output system seperate EMFL (engine management fault light ) engine control system is able to illuminate the engine light on the dashboard when the o2 sensors are faulty or giving un expected bad signals.

 

 

The system they are selling is primarily designed to work with OB2 as the 02 sensors circuit is completely active and can be manipulated by their system, the earlier OB1 is not active and if you have faulty 02 sensors your better off leaving them disconnected that way you get a good average signal, which is better than a faulty or out of range one, until such time you can replace them.

 

Any performance additions to the car that leave you in need of one of these systems is unacceptable, correct mapping and tuning is the way to do it not by giving the ecu false signals, in my view this is as bad as the Ebay "Tuning system" that a simply a resister that is connected into the airflow meter circuit which fools the ecu into overfulling:mac1:

Just the blanking plugs that came with the de-cats . :D
