You say you fitted the new amp 2 nights ago and the economy hasn't improved? My thoughts are the same as PhilipA's. I think you need to do a lot more kms before you can determine if you have a problem or not.
Average out the L/100kms over many complete empty to full tanks full to get your real figure of usage.
If you can get 16L per 100kms around town then you are doing very well!
The way I do it is to run the engine to normal operating temp,stop the engine, pull the connector off then measure the ohms across the two terminals. Should be around 300 ohms. If you cannot get a reading then something is wrong with your technique, meter or sensor.Quote:

I do not think you can asume it is correct if the idle went up, as the ECU may think its cold and raise the stepper in the event of the resistance being high.
15-16L per 100ks is IMHO better than is possible in urban conditions, so I think you may have initially miscalculated. The urban cycle for a 3.9 RRC is about 20 L per 100Ks and a disco is heavier .
Here are the figures from"Top car Guide " for a manual 3.5 injected Disco
City 18.6 country 11.7 average 15.7 L per 100kms and a manual is usually 1L per 100Kms better than an auto

The last bit was acopy and paste which I did not think took but did . it says the same.
If it idles up .... then it's adding more / extra fuel? ..Quote:
