Rover Gauge readings

[Robbo D]

Hi guys.

Just got Rover Gauge and ran it on my car. Below are a couple of screen shots showing the different lambda settings. How does this look overall please.

2nd picture looks ok, I would expect the idle bypass figure to be closer to 30%.
Could be that you have a slight vacuum leak somewhere.
Do you have issues?

Hi Belle.

I’m not sure about issues. Car idles fine now I have fitted a new genuine stepper motor. I was wondering about the lambda readings . I think my issues are coming from a Jaguar V12 XJS to the TVR and not used to the V8 feel. I have had plenty of V8s in the past with numerous Rsnge Rovers and a Triumph Stag.

Usually on a good running engine they will cycle around the mid point, plus or minus 10% is considered ok.

Short term trim that’s what I’m getting not sure on what the long term trim is showing though.

You have to select the checkbox to see long term values.
They are cars that like to be out on the open roads, moving them in and out of the garage a lot can foul plugs quickly.
Your never going to get Jag V12 levels of smoothness.
May be worth letting Frank here (blaze_away) analyse some logs for you if he's around.

Yes, no problem to take alook at the log data and produce some feedback.

You will need to run the files in a specific way as below......

Hi Blaze. I have followed your instructions and now have a couple of log files and an image of the long term trim for your perusal and advice. Please advise how I can send them to you.
