i have a fully built gsr top and bottom..
head is ported and polish
stage 2 brian crower cams 11.9mm lift
11.7 high compression
lighten crank 89mm
eagle ls rods
blox intake manifold
4-1 type r replica headers and full pipping
p72w/s300
do i have to trust base on the knock sensor if im tunning on the street?
because evererytime i shift from gear to gear
i have knock retard like -4 degree,
i kept retarding but it still showing a knock reatard....
what is the highest or best ign timing for high compression engine at wot and partthrottle?
because mine is kind a low. theres no knock retard on 22 degree from 5000rpm to redline ot wot....
and is it nomal to knock the engine from 20% throttle to wot and goes away for 1-2 secs?
i have a datalog but i accidently erase.. but i will do some pull tomorow and post...
can anyone check my calibration if its okey on the ignition is it smooth enough not to make knock retard

Agree,shes running a little cool up top.
The trick here is, never rely on a stock knock sensor on a stock engine to assess your state of tune.
Since u dont even own a stock P72 motor anymore,then your stock P72 knock board is listening to an entirely different motor,especially if u got forgies in there.
So if u cant rely on it on a stock motor,then what hope have u got?
The timing does look a little laggy,but u obviously realise this,as uve been pulling it from everywhere. Nobody is really gonna advise u on best timing online,nor should u really take their advice if they do,especially on such an individually setup motor.
U really need to get the thing on the dyno &/or at least in the hands of an experienced tuner who has the motor running in their presence & can tell what is actually right/wrong for your motor. If a dyno/tuner is not available,then prob best u park the car & start reading.
U probably spent a few dollars on that motor,dont blow it by cheaping out on the tune in the home stretch.
