2006 Holden Commodore (175kw 3.6 litre V6 / 4 speed auto).
I recently took my car down to Village Motors to have the ECU Updated as i've never had it updated, and they updated virtually every little computer in the car....
My ESP now works on the road and in the wet HORAY! lol .....
But the interesting part about this is, my tune file after I extracted it from the ECU grew 300kb in size...... it's bigger then other VZ's listed.
I found that interesting considering there's no extra options to change etc, didn't change my tune at all (which was unforuante) but anyway, I sent it to Bill at HP Tuners just incase he was interested in having a look for me.
We are still missing key things for tuning the car, so I'm hoping the update may help.
I doubt they'll look at it, but worth a try.
