Ok there is a difference between the airbags reset where the firmware itself was upgraded so the airbags went off earlier in the case of an accident as far as I know.
In theory it should only have been an upgrade to the firmware of the airbag module itself( yet another ECU ).
The odometer etc will not be reset as far as distance travelled on the truck.The mileage on the tank itself ( trip computer )to be honest I cant remember if thats reset or not but I think it is.Never took that much notice as I use the Scangauge to do all the real readings.
Marty when you try this can you put a multimeter across the terminals and see if you get any voltage .
If some are worried about doing damage as I can see some are then get a small wattage globe say 5watt or less ( the smaller the better ) and connect that across the terminals . If there is any residual capacitance then the low wattage globe will discharge anything slowly.
Now the guys in the US have been doing this for a while without any reported issues
Marty it was my incoming engine air temp that was reading high when I changed filter. The engine itself was cold as I left it to cool over night and then did the reset so it was a full and proper reload of everything
Like I said DO NOT DO THIS if you have any smoothing capacitors for your stereo as that will have a large charge and this will cause a spike .
Drum Roll thanks
Ok I drove the Nav for 30 k's this morning to get everything up to working temps , disconnected the battery and tried two things , one was Tony's way and the other was Ausssie's.
When the battery was disconnected the voltage stored in the system was 11.64v , thinking that might be a little high for the terminal discharge I decided to use Tony's method, with the battery disconnected I hit the ign key and turned her over , and yep you guessed it, click and that was about it.
Next recheck the voltage - big fat Zero and just to make sure I now earthed the leads together and still big Zero.
Restarted the engine and everything run smooth , Phew glad about that one as I was worried if the ECU wipe would require the Injectors to be recoded , happy to say they didnt.
Got in it and drove out the driveway I thought it was pulling better than before , nah must be imaging it goes better
During the day I drove as per usual and there has always been one section of road that let me know if the LPG is working or not, the normal scan gauge reading at best would be 8.1LHK not this time as it read 6.9LHK. Yeah sure you say , well lets put it this way I have not had these sorts of readings for a F@#$@ng long time. Ok I said I must have reset the scan gauge wrong, nope I checked and rechecked and it was set correctly with the setting I had written down before.
Next test was a long drive with lots of hills , some flat sections and more hills, at the end of a 130k drive my reading were far better than ever before, try 7.4LHK , remember I run Diesel with LPG so one would think the figures would be lower and I honestly feel that the Vehicle is back to what it used to be like so many km's ago ((try some 100'000km's ago))
Time will tell if I'm dreaming or if indeed something has been cleared from the ECU that had made the pump richer so to speak all this time, put it this way I have never been able to drive in 6th gear at 90km/h with the reves just under 2000rpm and still being able to pull out of it with ease.
I will do a full refuel tomorrow , diesel 150L and gas 50L , Zero the scan gauge and it about 3 weeks time I will know for sure, but for now I'm tickled pink and the spark the Nav had to begin with has returned fingers crossed
I must add , in the past when I used to carry out the pedal clearing sequence I had always done this with the engine being stone cold , and it now makes me wonder if indeed the ECU read and set the fuel mixture accordingly, this being cold and not hot like this time round
If this has really done the trick on my Nav, I wont bother with the Pedal crap anymore and just do the stored voltage wipe from now on
Cheers Marty
