Here we go! I finally have everything installed. Right now I just have 50 jets in there but I can swap them out for 35, 50, 75, 100, 125, or 150 shot. The performance shop said to start there and ramp it up over time.

I do have a few questions though on my setup. On my progressive controller, what does the "fuel offset" control and what should it be set at? at different hp shots as well?

I don't really feel the 50 shot being very solid though. Is this normal and will it get stronger over time? Obviously the 150 shot will be felt, but I read somewhere that our ECU's learn over time and will understand the shot better as time goes on.

You will see in the 4th picture. I have added a fog light button, that is my nitrous activation switch, stealth! Also, the button below on the right is a line lock! That line lock is so much easier on the car, highly recommend it!

I am currently also running a Takeda Intake, ISS Forged DES Exhaust and PPE Headers.

Thoughts?

I like the fog light button, where did you get it?

Also, on my G35, 50 shot felt like nothing. 75 woke the car up.

You might want to check the bottle orientation as well too, they normally don't like being put sideways like that.

Also for your fuel offset question.

Since your nitrous is a wet kit (nitrous and fuel), the progressive controller does a few things.

The two larger ***** control nitrous delivery time vs "strength".

So the second ****, duty cycle/strength is at 50% (or is it 40%?), and your time is at 4 seconds.

So your nitrous is at 50% (or 40%), and it takes 4 seconds for it to reach 100%.

So if you wanted your entire 50 shot, turn it to 100%, at 0 seconds. So the moment you hit your foot on the floor you'll get your entire 50 shot.

If you keep it as is, when you mash the gas, it sprays 40% of your 50 shot (which is like 35 shot?), and after four seconds, it ramps to the full 50 shot. So 35 shot, in four seconds time will be 50 shot.

Now, for the fuel offset. When running a small shot of nitrous you won't need the complete amount of fuel. So your jets are set at 50 shot, but what happens is at your 35 shot, you're spraying the amount of fuel for a 50 shot, meaning you are getting less power than 35 because you have too much fuel. The fuel offset will cause the fuel solenoid to react LATER based off of time. If I remember correctly, it's based in milliseconds, but don't quote me on that.

To dial the fuel offset correctly, you'll need to have a AFR gauge, or be on a dyno, but for a shot as minute as a 35 shot ramping to a 50 shot, it'snot going to make that much of a difference. Hopefully, that all makes sense.

So, the numbers on the fuel offset guage go from 0 to 20. Do I dial this up as i keep going with a larger shot???

Should i keep the 50 shot for a bit or should i just pop in the 100 jets and go from there. I cant really feel the 50, although I'm sure it would show in my 1/4 mile time by a bit.

I got the fog button from Toyota, they ordered it in for me. I don't have a lexus dealer in town so I can go there for parts but I have to go to a city about 2 hours north of me for service.

To my understanding, it would be going down to zero. I've never used this before, but I did look into it awhile ago on when I still had my G35.

To my understanding fuel offset is based in milliseconds. So 0 would be instant, 20 would be 20 miliseconds BEFORE fuel comes on.

So if you had it at 20, nitrous would spray, then 20 milliseconds later, fuel would spray. And if it was at 0, then it would spray fuel instantly.

Any track time yet?

Bakewalk

First time with spray, the car loves it! And i hooked! I had the progressive controller set to 30% @ 4 seconds.

Bakewalk

Densitity altitude was 4100 ft last night btw!!!! The calculator says a heavily modified NA engine would of been 11.21 @ 124mph!

What shot was that? I told myself I wasn't getting N2O but now I am starting to itch for speed again....

Bakewalk

150 shot with a progressive controller. 20% over 3.5 seconds.

lifethinkr

what kind of kit is that? I like the clean look of the solenoid block

What tires where u using? I run the same set up but i havent hit the track yet

Its a nitrous express kit. Had my local garage install it for me. They wanted to put the jets on the front side of the intake and curved the shot so it shoots the nitrous and fuel directly into the engine.
