i have a turbo gsr and im problems with my knock sensor sending me into limp mode. what should i do. i have heard not to just disable it because that can cause more problems down the road. i run 93 octane and the ignition timing is set conservatively at 14 degrees

 

if i stay in vacuum until 5000 then i can floor it and go. but if i floor it before then it will go into limp mode. weird...

 

I disable it most of the time. My buddies car used to do that same ****, on **** load of the compression, 100 octane and conservative timing. So I just disabled it and the tune turned out fine.

 

i had the same fk'n problem. get a chipped p28 ecu with a conversion harness obd2a>obd1

 

ive never run a knock sensor. ive got over 40k miles of turbo over the past few years with only 1 motor casualty due to a huge boost spike

 

Advance the timing to 16degree's instead of 14.

+1 and a dyno tune

 

well the timing was originally at 16 degrees and i backed it off to 14. its running a little better. i need to just get it tuned and screw this basemap. going in 2 weeks for the tune
