How are you doing it? This is gonna be mostly a street weekend warrior car with a direct port setup and stand alone. Probably be spraying a 200 shot.

5.7 ute

I used an Efilive custom operating system. (COS5)
Tune in SD as normal. Add a pin to the pcm that switches to earth when spraying.(J2 pin 56) & calibrate the nitrous tables. One table will adjust the VE to add fuel for a dry shot, another table is utilised to pull timing.
Using a stand alone wet system you would only need to populate the timing table.

BADMOON

When u say populate what are you referring to? Take more out?

5.7 ute

By populate, I mean to put values into the nitrous timing table of the custom operating system.(If you went that way)

BADMOON

OK thanks. I did put a digital MSD6AL in the car so I can manually pull timing

I have my own copy of HP tuners and had my tuner make me two tunes. I pretty much know when I am going to spray so I will load in that tune when the time comes. Otherwise I am on my street NA tune.

I tuned the map to be on the lean side at 90 95 100 kpa and let pe fuel at wot. If its a wet setup tune fuel with plugs, fuel pres and jets. My car likes a 180 shot with 12.3 AF, pullin 6* on an 8 plg.

the LT1 PCM won't like EFILive very much

COS 5 uses a 2002 LS1/6 Base tune and attaches the custom operating system (tables) to that.

If you cant run the 2002 tune on your PCM COS 5 is a no go.

I was able to use the 2002 tune w/ my 99 PCM, but I had to paste the matching 99 table values to 02 tables, and had to work around the tables that were different or none existing.

Up to 99-04 PCM's should work w/ Cos 5 I believe, LS2/3/7 (1024k+ PCM) Cos 5 will not work.

Enough interest @ EFI live and maybe the EFI Live boys will make a COS for the lastest PCM's. Last year I remember asking for a COS for LS2's but I do think that happened.

Yea I probably should have mentioned this was an LT1 car in the title..

I have nothing against runing speed dencity but in my opinion you need to be able to stay on top of the tune and understand tuning in order to use it with nitrous.
