The LC1 would be more accurate , they get returned to the factory for warranty repair every 4 weeksOriginally Posted by ringram
I have a heap of PLX , a LC1 a motec and an autronic meter and I would say the PLX is the most consistant of the cheaper brands , at stoich all mine are out by 0.1 -0.2 AFR but everywhere else they are spot on to the autronic and motec meters.
When on the dyno I have a plx in the car 90% of the time and the autronic on the dyno and they always match.
