VE table for 383 Supercharged LS1

[02_TA_RamAir]

Anyone have a VE table for a 2002 Trans AM LS1, 383ci with a Vortech supercharger putting out 9psi?

I have one but its for a Camaro, not a TA....

It doesn't really work like that man.

Are you doing a 2 or 3 bar speed density tune? Injector size? Cam?

[02_TA_RamAir]

Right now I have a 1 Bar MAP. My injectors are 42LB/hr and the cam is a Z06(.550 lift 205/218). MAC mid length headers, high flow metallic CATS, Patriot heads. Forged crank, pistons & rods. I have a looging run and found that I pegged the MAF & the MAP (of course). The AFR (using wide band O2 sensor) indicates around 11.8 thru out most of the rpms

Without a 2 bar custom OS you'll only want to tune the VE table in part throttle areas. Pointless to tune it for WOT.

Could anyone post VE table for 383 Supercharged LS1? I'd like to compare it to my 383 9.2:1 CR (part-throttle, of course) so I'd know I didn't screw it

You'll probably be able to find more boosted 370's...which will have about the same shape VE table.

You'll know you didn't screw the part throttle portion of your VE table when you monitor your fuel trims.

Actually I turned off all my fuel trims and I'm in open loop 100% of time

Think this should work.... try and take the ZR-1 Virtual VE from say a 2010 (repository has files), download constants into the Blue Cat tool, generate the VE table in LS1 format, select VE% and the table should look like a standard LS1 VE table.

Just an idea if you can't find anything else. The ZR-1 is a 383 with around the same boost.

does this look good (low-load cells, up to 2400 rpms only?)
mowton, thanks, I'll think about that tomorrow...
