COS5 is the OS you want for n2o. You might send a PM to Black02SS or Beer99C5 for help setting it up.

Tuning in.. Please post anything you find out, I'm pretty interested in this.

Here you go gents. This is the shiznit! Don't settle for any immitations, this is the real thing baby!

Is that really all there is to it? Pretty sweet!! So whenever the pin is grounded, those conditions are met? How is your nitrous system set up? What do all those switches across the top do?

I am still setting mine up, Doc I did not know you were running it to. I just reviewed the tables TAQ helped me switch from my 99 OS to a 2002 Vette OS and will be loading it next week.

Here is what I am planning.

Two stage, 100 Dry, 100 Wet, either will work with the NA Tables as single stage.

When i want to go with the 200, both stages will be activated, I will use the nitrous tables in COS5 by flipping a toggle in my console.

Not my final tables but screens of what you can tweak.

When does that iat ve multiplier come into play? Is that only when the pin is grounded, or is that constant?

[Doc]

Sorry about the poor picture. The foglamp switches are as follows left to right. 1) Fog 2) N20 Heater 3) N20 Master Arm & Stage I
4) N20 Stage II . #3 is wired up thru a double pull, double throw relay that provides 12vdc to the WOT switch/relay and the ground for pin 56 to utilize the COS #5 N2O settings.

I'll say two things - I can't tune with COS5 yet - I know someone who can and it works real well. I have never run so consistently at the track as I have run with a Nitrous Outlet single stage 200, FJO Mini Controller adjusted for the various (and few) tracks I run and a COS5 tune that makes it all come together like never before! Anyway - at least I own all the software and study it endlessly!! Example times form a month ago 10.52, 10,58, 10.53, 10.55 are sample times I ran with the streety version of my car. It's pulled completely apart as it's being retired from School Bus duty and getting a new 2 stage nitrous system. I'm heavily considering a wet first stage for 150 out the hole and then a DP Dry 250-350 kit to pick up at the second gear shift and carrying me through the timers. Now COS5 seems like the real deal for this - what do i need to consider for the Dry DP??

Now - I may have to start a new thread like my LS1tech
