1st Build 240sx LS1 swap HELP Hello, My name is Gio and I'm deaf. Currently I'm done with build engine L33 block with milled port 843 cylinder head. CPR Engine is the one who rebuild engine. my point is I'm try get PCM tune set up for my engine. I have custom ground camshaft "Isky" but I'm not sure what number because CPR never tell me. Cylinder head have beehive valve springs and stock rocker arms. i believe ls2 lifters guides and valley cover. D.O.D. removed. crank has 24x tooth. ls2 2004 knock sensor or should I get ls1 knock sensor tapped new thread on L33 block? I have custom standalone engine harness from gen 3. LS1 intake manifold with stock TB and firebird accessories. Truck maf. The guy who made custom standalone harness gave me 2003 tahoe PCM told me to need re-tune for isky camshaft. Now i need your help where should i sent it to company tune PCM or get holly efi but i don't want to pay over grand?
many thanks

Sorry I wont be of much help Gio as I am still learning but I wanted to wish you luck on the 240sx build. I currently have an LM7-S14 I am slowly working on. I would say if you have the harness keep it simple and get an HP tuner and go from their. Because your setup is a bit more elaborate with custom cams and a built block I think it would be best for a tuner or someone that knows what they are doing to handle the tuning in real time. Just my 2 cent.

Do they not tune the oem PCM or do they not tune the oem PCM using HPTuners? HPTuners seems to be the most widely used application for tuning the GM setups from my observation.

HP tuners x10000 especially if you can get it on a dyno and have it tuned in realtime. Sorry to hear about your loss of hearing, LS-engine is one of the best sounding v8 engines. Good luck with the build, I will be lurking
