I was wondering what ECM /harness do you guys use to power your LSx's when you swap it to a turbo?

Any good write ups on a conversion for a NEWBIE?

Thanks

Same harness, just different tunning and injectors.

Can you use a stock GM puter? Don't you need something that is boost sensitive?

You can use a stock ECU and hp tuners 2 or 3 bar custom operating system.

That would allow you to tune it speed density (no maf) and read/tune up to 15psi (2bar) or 30psi (3bar) boost.

Like Jim said ^ the stock ECM can get you pretty far without having to go to an aftermarket engine management setup. He tuned a vette I finished a little while back and it made 847 to the wheels through a TH400 on a HOT day with the stock computer and high impedance injectors. Just depends on your goals I guess.

for fuel you will want a boost referenced fuel regulator. that way you fuel psi will ramp up with your boost. me pesonally, i would get it tuned in speed density
