SV6 Trip computer functions

[stew7700]

Gday all, picked up my SV6 on wednesday night and have been fiddling with the trip computer functions. When you hold mode and set and turn the key on, sum of the functions u get are instrument temp.. and "switch voltage'.. does ne1 know what instruments that would be..eg behind the speedo and tacho or..instruments like the cd player etc.. and what switch they would be talkin bout with switch voltage cuz it has me confused haha
And does anyone know of any otha functions u can get up otha than the basic ones?
thanks, stew

Really other than voltage, temperature & rpm, I think the rest are pretty lame. I'd like an instantaneous Litres/100km, and few more fancy things in the normal computer screens as well. 99% of the time I have the speed or overall litres per 100km on the screen.

The seat voltages seem odd - anyone worked out that the hell they mean? Thy dont change with a person in the seat, the seat positions, or the seatbelt on or off.

yeah and ADC brake reading what the hell is that? and whats with havin the fuel parts used out of 255 lol. But yeah it needs some more things on the normal screen i think. btw i like your blue dash mate looks good.

its all diagnostic information, no real use to you because as you said you dont know what its all about.lol

Cool ... while you are at it ... correct me if I'm wrong, but, the accelerator pedal is linked to the engine in the VZ SV6 via a 'electronic' method and not a cable ... does this mean the computer controls the acceleration rate?

I am finding that regardless of the pressure to the pedal the acceleration is still the same and 'controlled', albeit smooth and still with some force, but not to the 'grunt' I would have thought the 190kw beast would produce.

Also, can the 'traction control' be set via the computer chip? I am find that at a low take off spead the 'traction control' inon shows on the dash display indicating it has 'worked' when there is bugger all pressure to the pedal and wheels, so I am thinking the traction control settings needs tweak.

Any thoughts? Anyone?

[Doctor Bob]

The ECU controls the throttle blade yes, it is called a torque on demand system, it will only give enough throttle to achieve the torque within the design parameters.
The trac is controlled by the ECU & ABS/TRAC module, nothing in the ABS is programmable.
at present there is nothing available to reprogram the alloytech engine management system...yet

Any updates on this Dr Bob? Just interested in what all the other things mean.

Hi Doctor Bob. Can you give us some advice on CAI kits for the VZ V6 please.
It is all very confusing at present.

You can blame the 2.78 gearing for that. Change the diff ratio and I'm sure it'll feel like a totally different car.

When i tried it on my vz ss ute, its told me battery voltage, tacho reading park lamps on or off, trouble codes, coolant temp, Litres per 100km, speed, seat voltages and a few others.

Was that a couple of hours or a couple weeks ...

Come on Doc, don't keep us in suspense ...

Thanks for the info on the electronic throttle ... does that mean I should turn off my mobile phonee while flying, oh, I mean driving .... or could I tune the ecu via my phone!

I've read a few guys posts saying they were changing diff ratios, but mainly auto's not manuals, what doe it cost, and what does it achieve?

Can it be done to a manual?

[bdcmedia]

Seat voltages would be for the Statesmans ect that have memory seats thats move to the drivers last used position I would imagine!!!

yeah come on matey, we're keen to know!

how are you getting these readings up on your car i dont know what to do?

can anyone else help?

Turn the ignition off, hold down mode and set and turn on the ignition. You are now in the dianostics mode.

My guess is switch voltage is all the buttons etc that you can press. Fuel is shown as xx/255, the SV6 has 75L tank so just do the maths, or keep pressing mode and you will come to litres left,

Doctor Bob, we are still waiting for more info.

[Doctor Bob]

for all those wanting to know the "secret"

ok once in diag mode the displays are as follows


between each display press mode

Down Button 2.43 to 2.71v

these pretty well explain themselves

Is the seat voltages one not for the seat belt alarms, but because they are lower spec cars they are just not there?

[sincy]

does any one know why i dont have some of these options (ie- voltages, instrument temp etc) on my ute.. it is a base model, im thinking that maybe the reason??
