Hey guy's I swapped a LQ4 into my 240sx rebuilt the engine with ls2 pistons and rods 5 wire maf stock ls1 intake stock cam etc also running a 2002 Lq9 6.0l Cadillac Escalade ECM. Feels faster at half throttle than full throttle so i plugged my scan tool in and log timing,throttle and rpm would have log knock but my scanner doesn't have that option. only getting 6 degrees of timing at full throttle plus i don't hear any knock.Thanks for the help

You need to post up the tune and log in order for anyone to help you... could be a number of things...
