I have a 00 Trans Am with 02-OS and in semi open loop COS5 ,I'm ready to do some nitrous setups .I have a duel stage nitrous first shot will be a 100 shot (dry) and 200 wet fogger , The wet fogger works perfect , But now I'm ready to setup my COS5 ,I have the J56 pin on a micro switch to ground and now i need some help setting up the parameters in the Custom Calibration. What do i need to tune on and witch parameters need setup for the dry 100 shot ,Mass Air is deleted
Thanks,Randy

I chose to use a switch to active the tune, some choose to have it automatically ground with the noids. Once you get it set up your looking at this table to get around the MAF delete or add fuel w/ the MAF as well.

To add fuel you need to up the VE mult to say 1.1 (my estimate for my dry shot w/ the MAF). I would guess yours will be higher depending on the size shot.

You can pull timing w/ this table

Here is the setup table

I was looking at the VE Multiplier ,http://www.retrorelics.net/jim/Boards/EFILive/EQ%20for%20Nitrous9703DLFeb08.xls and it only goes to 6000 rpms, I need to go to 7000 on a 100 shot dry.
