Is this just a tachometer malfunction?
Just picked up this FA5 about a week and a half ago now and I noticed something kinda weird. The vtec in this car engages at 4400rpm and revs to about 8700rpm according to the tachometer. I messaged the previous owner about this and he said the car had never been tuned and the only thing that is done to it is an injen intake (does not require a tune like others) and some hasport motor mounts, it even still has the stock exhaust. Does anybody know what could cause this and should I refrain from taking it to redline? If I remember right aren’t these cars supposed to engage vtec around 5500 rpm and limiter is at 7800-8000?
