this isnt a modification of sorts. but heres what happend.

normally my cars dte reads 394km after just filling up (that's what I get when I use the odo as well)

when I got home from the shops, my dte said 298km.

ive just bought my gauges and wanted to take off the icc to take a look (didnt manage to though, could some one tell me what to do afda I remove the screw and the bolts)

before I started trying to remove the icc, I disconnected the negative terminal of my battery, and when I reconnected it, (about 20 minutes later), my dte read 378km!!

so I gained 80km just by disconnecting and reconnecting the battery?

what gives, so far the odo and the dte are still agreeing with each other, im one bar of fuel down and the dte still reads 358.

could someone explain what happend? and how to remove the icc. thanks

Do a few laps of the block and your DTE wil recalculate.

yea I drove my cousins home, which was about 10km, and the dte still reads pretty accurate. I remember reading someone say that the ecu gets reset when you disconnect the battery? could it be that my ecu didnt adjust to the 2nd cai and air filter properly (I doubt itll give that much better fuel consumption though).

:S

Yes it does reset after a while.

In a nutshell the DTE continually adjusts as you drive based on your average consumption and what is left in the tank. It doesn't suddenly realise that you've changed the filter and adjust immediately.

oic. what I dont understand is that when I turned the car off it had 298. and when I turned it back on, it went up to 378?

I drive pretty normally, but what I dont understand is why when I turn it off and back on again theres such a big difference?

itd be alrite if it was close to what it was before, but on a full tank, when I reset everything, the dte reads 394. yet when I reconnected the battery, one bar of fuel was already gone and it still read 378

Man your fuel economy is

Its not uncommon for the fuel gauge to read incorrectly (apparently there were a few faulty ones early on)... how much fuel do you put in when u fill it up from "empty"

[XR68UZ]

yea I got heaps crappy fuel economy. two days ago I filled up 61L (about there). cost me $90!!!! im hoping the new found 80 kms will change how often I have to fill up. driving to uni has been restricted to fridays only, due to the rising fuel prices. that dam tax!!

When you reconnected battery did the litres/100 change as well

everything was at 0, except for the dte, and the odo

You drive around with a super lead foot don't you???

Since the PCM is a self learning module, it will memorize your driving habits and calculate a predicted fuel expenditure as a result.

Fill your tank up all the way next time, disconnect the battery once doing so, then drive around sensibly. You should notice that your DTE should be up around the high 500's.

I used to suffer from a bloody gimp right foot like yourself, right up until fuel hit $1.40 a litre an stayed there.
