Because if it was running so 'bad' before its going to feel much better anyway

I thought for once we were going to get some firsthand comment on how good the chip is. Guess not!
And more importantly, if it's worth it.

Does anyone know if anyone on Melbourne does this type of thing. I have heard plenty of good things about Bruce David but I would prefer to take the car in to someone in Melbourne.

Well finialy got home, yes I agree it's a shame the way the cookie crumbled with the oxygen senses and air flow meter but on the plus side HOLY HELL!! It honestly feels like a different car! I put my foot down and she gets up and goes like an SS or XR8... There is a huge difference but like you guys said its hard to assess the difference that the chip made overall I'm still happy there is a huge difference in the sound of the exhaust note and like I said put your foot down and it's at redline incredibly fast... I will be filling the fuel tank up Tuesday so I will post up the economy difference, Bruce was saying that with how the car was running it should have been sucking petrol like its running out of fashion, when I told him my fuel economy he was shocked... Would anyone know why someone would unplug the oxygen sensors? Oh and he can reflash the 4.6 I'm pretty sure for about the $600 mark

I have had the ecu upgrade for quite a while now....
Its worth the $ and the performance is noticeable .. I'm running 235/85 tyres.....
Towing a 1.7 ton caravan is a lot easier with the extra torque...
Fuel wise I would say its slightly better...
I have recently towed our van to Brisbane and was very pleased with it
Well worth the coin......
Cheers smally

If a scientist was conducting this experiment, he just through the test tube in the bin and turned the bunsen burner off. (& cracked a beer).

I would be interested to see a chap with a D2 who is currently achieving 16 - 17 litres per 100 in city travel have the chip installed. Then give us the run down. I would love even more to see V8 driver stick it to the Td5. Not that V8s are not already doing that.

By the way Dan, I'm still happy you have your rig running like it should.

Regards
Andrew

Good luck

Dan, glad you're pleased with your results
I'd be happy just to have mine drivable, I hate driving my toyota

Disconnecting the O2 sensors allows the engine to run "open loop" i.e. to a predetermined fuel map. Perhaps they thought they'd get better performance than having a dynamically adjustable setup which is what happens with properly operating O2 sensors i.e. a "closed loop" situation.
Some vehicles run open loop until the engine reaches correct operating temp. ...at which stage the O2 sensors are switched on and the vehicle goes "closed loop"

0pen loop defaults to a rich tune...goes hard but I gets poor economy.

Cheers
