Running 6 psi, supercharged Ls Vtec @ 12 deg, boost will only be 4/5 psi. Though while @16 deg boost it will peak 6psi but have detonation in low rpms. I need to know what should the timing be?

10 degrees on 6psi set up is good, what ems are u using? if its the stock ecu and an fmu just set it at 10 degrees, or u can use a chipped ecu and retard timing per pound of boost.

 

MOVED TIMMING 10 DEG RUNS AT 6PSI AND RUNS BETTER but now through a check engine code 43 fuel supply system only some times .thinking stock fuel pump ,injectors ,fmu are the cause .any info would be great

 

quick question...what do you use to read ecu codes?

 

there is a service connecter plug located under right hand side of dash .you need to loop it with a wire then check engine light should blink slow for first diget fast for second.for example one slow two fast = 12.codes are in haynes manual .

 

yes u need to ugrade your fuel system at boost u might be running lean that what my did thank god for the air-fuel gauge i would have kill the motor
