:eh: I wasn't talking about oil pressure. I was talking about the tach signal. Because if the guage seems to be accurate but the VTEC point is varying maybe it has something to do with the ECU's tach signal, if it is a different one, which it probably isn't. :dunno: But if the ECU's signal was not accurate thent the tachometer would probably read a varying fuel cut off too which it doesn't so it must be something else.
