Rovergauge and lambda data

[blaze_away]

I've been helping a fellow TVR owner sort out there car which has intermittent hesitation during normal driving.

In evaluating the Rovergauge data it appeared to show some unusual lambda output on the odd bank. To verify it was a defective lambda the owner switched the lambdas over and rerun a logfile.

The chart below clearly shows the fault moves with the lambda. Chart below clearly shows intermittent 0 to max swings. Left side of the chart is original setup and right side is after switching the lambdas over.

Hope it helps someone in future

Pays to change them really as they get a hard life, not sure how available they are without paying the TVR tax.
