I can't seem to get anyone to answer this question!!!!!!!!!

I have a supercharged LT1 camaro, with the new HOLLEY 58mm NOS TBI unit. I plan on setting my power at 100hp for the NOS. Holley says for me to use a 47 jet for the NOS for 100hp. My question is how much FUEL do i tell the ECU to add????????
Is there some kind of formula used to determine the amount???? I know NOS is tricky, so i am not looking for exact numbers, i just want a safe starting point!!! I can handle it from there, I think.


thanks,
james007

I'm going to go out on a limb to say you probably didn't even contact anyone that I told you to last time.

I can GUARANTEE that Jeff Prock can help your needs. http://www.appliednitroustechnology.com/

Ya may need to be abit patient with him as he is abit of a busy guy, but one of the best in the business when it comes to nitrous. he can also write a base program for you for your Speed Pro, beit just for the Dry N20, or even the motor too.

Have you tried posting on this board? http://www.chevytalk.org/cgi-bin/ubb...=20&LastLogin=

Craig Smith the EFI tech from FAST posts regularly on this board as well as a lot of knowledgeable guys. I am very familiar with the FAST ECU but I've never tuned one with nitrous.

First off, you need the N2O add on computer for the F.A.S.T. System to be able to handle a N2O system (dry). C-com has the provisions for any type of Dry Nitrous system, once you have the actual second computer.

Uh, where did you hear that from? The FAST PCM comes standard with everything you need for a dry nitrous setup- there is no external computer needed.

To set the dry system up, simply run the switched 12 volt nitrous activation wire from the FAST pcm harness to a relay that activates your nitrous solenoid, program the correct fuel pulse-width adder for the size shot you're running, and thats it. He just wants to know what size pulse-width should be added to the base pulse-width in the PCM for the size shot he's running.

 

Actually it is an option for *Nitrous Options*. Not saying he doesn't already have it though. True it isn't an external Box, but if the box didn't have the Nitrous Options from the Factory he'll need an update/upgrade from the factory, by sending in the Box to FAST directly.

Of course he has it, since NITROUS CONTROL IS STANDARD ON ALL FAST PCMS... Just like nitrous control was standard on all SpeedPro PCMS... and Felpro PCMS... No updates or upgrades needed. The only nitrous "option" is for those who want their PCM setup to run 2 or more stages.

 

So it is! Just looked at the Part # Index on FASTs site. Guess I bought 2 more stages and the down track fuel trim for no reason when I didn't necessarily need it... Oh ell, better to have then have not I guess!

Thanx!

James shoot me a e-mail. I can tell ya where you need to be.what % of the injectors you usin now without the jug?

 

Looks like I was mistaken, I thought the system had a N2O computer "option".

My mistake. Good thing sombody pointed it out though, because I've thought that for a long while now.

every bank-to-bank ecm has the n20 options on it....

BUT

that doesn't mean they are activated for use because of the limited amounts of inputs/outputs of the computer itself

FOR EXAMPLE

take my computer:
b2b
wb02
fan
fuel
iac
n20

that is the standard hei type package.....now the nitrous is there, but it wont work if i hook it up because of all the other options i have. I would need to get the fan disabled and then run the n20

only way to run all of the above is with an IPU ignition type

 

True, but why would anyone in their right mind want to sacrifice one of the nicest nitrous managment systems on the market when they could leave the simple task of turning the fans on and off to the factory PCM? Doesn't seem like a trade that most people are going to make...

 

because some of us also dont use the factory ecm with the fast

and im a boost junkie
