p06 converted/ vtec 6.5k rev limit?
 

i got a 95 hatch w/ d16y8 and p06. my revs max at 6500. ive tried two diff virgin p28s and a converted p06 w/ phearable chip (d16y8 maps) 4k launch and 7200 rev(which i currently run). still only does 6500. lauch works fine. all three rev to 6500. no check engine lights, no hesitation, starts up fine. any help greatly appreciated.

car is a dx wired for vtec by previous owner. just checked wiring and a4 to vtec solenoid and d6 to oil pressure, so wiring is good. oil pressure is grounded at vtec solenoid w/ a good ground.

Sounds like your tach maybe off. I have seen this on several vehicles.
Is the vehicle throwing any check engine lights ?

no cel.

does the vtec oil pressure sensor run reverse polarity? the wires in the clip do not match all wiring describe in any write ups i see. could that be it? or would it throw cel?

It would usually throw a cel if it was not functioning properly.

yea all my wiring is good for sure. maybe tach is off but rev limit is where it should be. ill reset my ecu i doubt it will do anything tho
