Hi.
I own 1995 HSE this model of rover in Australia do not have oxygen sensors fitted as original set up.
I did change injectors to aftermarket type and they are running 19lbs not 14lbs as original so I end up with rich mixture ang bigger fuel usage them before.
If I can fit oxygen sensors ecu will change time for how long injectors are open by checking exhaust gases This is the way I think is working.
Can anyone help me with this problem as I ask few people in Melbourne and they are not sure if ecu can support sensors.
Thanks

I would assume you would need to fit the relavant ECU that runs o2 sensors, BUT why not just fit the correct injectors???

Hi.
Thanks for that .As to injectors i got them for 1/5 of the price .
I do not know if the ecu in my car is able to process info. from sensors or as you pointed
I will need new ecu but is this " new " ecu able to work with bcm that is the big question mark and I know some people who work on RR for 25 years and are not sure using tekstbook and looking at all the info I'm not sure .
So I'm not going to cut holes in pipes and try fit sensors if this information can't be processed by ecu or if I change ecu my bcm wony be able to work with it.
Thats way I ask the question.
Thanks for your replay you are only one who answer so far

Did you post this on AULRO Forum??? I remember reading something, and have been thinking that it will be possible, but...

1. You would need to make up your own loom to the oxygen sensors and plug this in to the relevant pins on the ECU, which I believe is the same. Unless someone can confirm that the ECU is different ( i think unlikely)

2. You could just buy a later Engine loom off a car already fitted with Oxy sensors (97MY - I think) and you would then need to change the settings in the ECU using Faultmate or similar. Remember though that in 97 they changed some connectors/plugs such as the Cam Sensor (ask me how I know), so you would need to change this or splice the new plug on.

Maybe its on the discos/rangie classics that came with an optional (or someone made one) loom for the sensors. TRS were of the opinion that mine would not be able to compensate for the higher Compression Ratio (9.55:1) and Cam (PC216) unless it had Oxy sensors. The Oxy sensors provide some very vital information to the ECU and without them the ECU has very little to go on. MY analogy would be a blind person trying to see if a light is on. They know they've turned the switch, but is the light on or has the globe blown.

I'm really curious about how much you saved, against how much the additional work is going to cost!

Hi.
This is very interesting .As to loom I can see two plugs on the side of oil pan and some wires running from them so I think loom is present as if is connected to ecu or not this I don't know .
This cars were make for English market and is possible so the oxygen sensors were req. in England so they fitt the loom and this time cars for Australia did not req. oxygen sensors so they didn't fit them and maybe ecu is taking reading from oxygen sensor and as they are not present ecu work in defoult setting .This will be nice .
Just me thinking .
As to qestion if I post this before this is first time.
Thanks for the information .
And this is not the money just to see if this is possible

Hi.
I did look for the plugs for oxygen sensors on sides of oil pan I have plugs with wires coming out of them so harnes is present onlu question which sensor to use?
Will the ecu detect sensors on it own or do I have to use tekstbook?
Thanks for any info.

maybe check the schematic, and run your own wires to the ecu, it's only 3 wires a side.

or you could try lowering the fuel pressure
