Forged Rb25 Power Fc Engine Light Flash High Knock Reading Help Please.

[maka123]

Hello Nissan owners

Right im after some much need help i have an r33 with a rb25det built motor done 3500ks.Has a power fc im having high knock readings

at about 5500 rpm 3rd gear engine light will flash my tuner said its false knock as it was only happening in one cell.An he advanced an retarted

timing to check but the knock was still the same.He seems to be a good tuner an tunes Rbs on the regular.

Heres the sequence

start car knock max reading of 7

driving normal change before 4000 rpm max reading 14

thrash car 2nd gear 6000 rpm max reading 88

thrash car 3rd gear 6000 rpm max reading 97

now i can take it t past 6000 rpm to 7600 rev limit an engine light stops flashing knock reading doesnt get higher.

I cant hear any knock or pinging an tuner said the same he triple checked that it would be fine so he said

But what would cause this?Is it false knock have other people had these issues i dont wont my motor to detonate.Its a

worry an dont want to thrash the car anymore until problem is solved any help would be much appreciated cheers
