I'm sure it can be done, but I don't think you even need to swap the ECU's.FSO said:Thanks guys.
What I'm after is to use 1997 ECU on my 1995 HSE . So I can use oxygen sensors as my car did not come with them in 1995 in Australia.
I think if I use 1997 ECU this year Australien models start to use oxygen sensors I will be able to run them on my car which is 1995 but all the oxygen sensor looms are in my 1995 car.
Please correct me if I'm wrong. But I think this can be done with 1997 ECU and my BCEM.
No,its as I said,your screenshot shows readings from a generic scantool that probably cant be trusted on a LR product.All Gems is 5-0v.LarryS said:titianias can be 0-1volt or 0-5 volts, i stand corrected on the zirconias they are only 0-1volt, also the titania sensor don't create voltage as i had stated they change their resistance, anyway i have a screenshot of obd realtime i did last week as i was trying to make sense of long and short term fuel trim, this shows the real time voltages - this is in closed loop and flip every couple of seconds, apologies for any confusion mine (4.6hse 1995 uk) shows a voltage of 0-1.2volts.
Could it be that the plug change also is the change to a 5 volt sensor?
Yes,if its working properly the sensors should switch from 5v,(Lean) down to 0v,(Rich) around once a second,quicker as the engine speeds up.On a scope the 5-0v Titania's give a much nicer trace than the 0-1v Zirconias,and I would guess its easier for the ecu to make good use of the info.LarryS said:This is interesting and thank you for that info. So if i were to take the voltage directly it would not show the 0-1.2v fluctuation that the scantool did but would actually show a 0-5 volts flip flop, is that correct?
