Hi there, thanks for the reply. I've asked him how the car is going tonight. After checking fuses he had found a few loose-ish ones, and pushed them home firm. He'd taken it for a couple of drives this evening, and it seems to be going good. Tomorrow if he's home ill go plug in, and check the system...

Hi there A mate of a mates wagon has been playing up for around a year. Caught up with him a few nights ago, plugged in with tunerpro and aldl, got code 49. So I suggested replacing the crank angle sensor. We replaced it today. Also we cleaned the cam sensor. While we were at it, checked the dfi loo...

Ahh ok, so its more for real time tuning at a guess?



Heres my log taken during the drive to work this morning, attached

I'll post up my log later on, I logged on the drive into work today. I saw the oxygen sensor in double digit yellow and 3 figures in blue and red. But I didn't see the calculated VE change, if it should?

I could swap back to the factory memcal, and see if that makes a difference. But from memory, I don't think it will.
How would I go about checking the VE ?

Cheers

Edit: my last tank of fuel I got about 570 to 580kms highway and city

Hi

This is the VR V6 just the one oxygen sensor. Brand new 2 weeks ago.

The oxygen sensor data is in the most recent data logged a few messages above.

Cheers

Edit: photos of sensor data attached

Kaiapoi NZ, on Google it says we are 6 meters above sea level. Could I still be chasing a bad intake manifold gasket? I do have one here to replace. Could it be a Crack in the exhaust manifold that's playing a part? Having a sniff at the exhaust end, it smells a bit rich. Today I also swapped over t...

I have taken a few logs of sensor data, I'll have to post those from the laptop though. It has new plugs, leads, and have checked for good spark with spark tester, all strong looking spark. It also has a new oxygen sensor. What else can cause it to run rich? Today I sprayed Carby cleaner around the ...

Hi there ,all that commented, I'm loving the input :thumbup: Looks like I have a better way to test the sensor. I did also start a vacuum thread, in saying this I will get around to doing the can of spray trick around the intake to check for a possible leak? While doing this, listening for a smooth ...
