Well finally got my noids back and it and thought I would test it out on the 100 shot. Takes off ok seems to hit ok up to 5500 rpm or so it feels like it dogs out or loads up with fuel.

I tried it again but this time turning off the spray when I felt that bog at around 5500, it came out of it on the motor right away.

So either I am getting to much retard...., or fuel.
I don't think it's KR since I didn't hear detonation, didn't have time to hook the computer up last night to see for sure although.

I got out the ole instruction manual and I never did understand that part in back about progressive retard control for boosted applications I am thinking that may have something to do with that and how the dials are set giving it more retard as you climb up in RPMs.

Right now I have the dials set at:
RPM....3K ( for nitrous on)
WOT...2
Base...1
Retard.4
Modes switchs are all off, but #4 is on for Max RPM NO2 shut off.

So my question is does that WOT and Base setting have something to do with that progressive retard option for boost..
Or is it what I think it is and just 1 deg of advance through the whole range of RPM and 2 more degrees at WOT making 3 degrees total at WOT.

Guess if nothing else I will put the 50 shot jets in and run it the way it is and if it dogs, then turn all the settings to 0 to see if it still does it with the tuner disabled.

Thanks for your time

How much nitrous is in your bottle? Whats the pressure at? I will look at the instructions I post in the wiring diagram and see whats up, if I can tell. I sold mine w/o ever using it.

I ran about 1050 psi give or take on the bottle before made passes with it last night. I guess I never looked at the pressure when it was ******* out, but after each pass I checked the gauge and it was right up there. Not to sure how much is in the bottle, I will have to weigh it up when I get home. I have a worthless 15lb bottle, when it gets down to 5-6lbs it doesn't hold.

I have it wired up correct.

Anyway there is a page on the back that has Settings on top of it. That is the page I don't understand, I assume it is for boosted applications that the Retard ramps up with the RPM. I will post a scan this morning as soon as I get home

Here is a link to the instructions in word.

Just checked the bottle and it has 11.5lbs left. So that is good to go.

Going to have to take it out later and see if there is KR. No KR pulls 27* of timing at WOT.

I posted the instruction for the TT in the wiring diagram stickie Yes it seems kind of confusing looking at it. I see the base is added to the WOT (under WOT conditions). Where is the retard 4 coming from? On a stock tune, you dont need to pull any timing, try running w/o any timing being pulled. With the load up your talking about, sounds like its more of nitrous not flowing but fuel is, dirty filter, cold bottle (low pressure) etc..

This is the page that really confuses the F&ck out of me...

I've got a TT that I'm installing soon, and I don't reaaly understand that last page either. I don't really see how you know if it's set up to pull a set amount of timing, or increasing RTD with RPM.

Another question, where would be the best place to put the FPSS? The grey wire?

Welp I found my problem, I am the retard....... I had the nitrous and fuel jets turned around.. To much pride to check that first, before blaming the tuner. Had it in the back of my head the whole time but never thought I would do anything like that....

I am not 100% sure but I think I remember wiring up the gray wire to the power on the relay. The relay now gets it's power from the TT to open and close the noids.
It's been 2 years since I did it but I remember struggling with that also....

I think the grey wire grounds the relay, which is where I currently have my FPSS.

Your right....

So, in theory, the FPSS should go on the ground side right?

It can go on either side but most people, even myself, have their's wired into the ground that the W/S provides. Like this diagram that one of the CAT3 stickey'd

i run the timming tunner and the have it set ot come on at 3000 and off at 6200, and the only other dail i use is the rtd witch is the one that pulls timming only when the spray is armed, my base and WOT are both at 0, and have had no problems what so ever.

and as for the fpss dont run it inline with the timming tunner as if the fpss gets triggered it kills the crank single from the car and the car turns off and when it come back on makes a big BOOM trust me i found that out hard way, so i by passedm y fpss and no more problems there

WS6HUMMER

What happened to make the car loose fuel pressure? Also what made the boom or backfire?

calongo_SS

iTrader: (7)

Anybody else have anymore input on this? I don't understand how a FPSS is going to kill the crank position sensor signal, especially if it is hooked up on the + side (in series w/ WOT switch).

my fpss switch was bad when i got it whould trugger at 55 psi and no matter how much i adjusted it whould not help, so i did away with it. and keep a eye on my fuel press gauge and it never goes below 55 pisi

I don't run one now either.....

Yea back in the day I ran one also, but my first NX one sprung a leak and was a fuel garden sprinkler under my hood in rush hour traffic, and the other did the same junk as yours,.. had it set for 38psi (for IROC-Z).

I have had both replaced and my third is still on my tool box collecting dust, never installed it my current car.

ALSO when you set your Max WOT setting on the TT which dial do you turn for the RPM max the WOT or RPM...?? Either the tuner is screwed up or I forgot which dial to turn. Mine is stuck at 5900 rpm.. I would like to bump it up to 6500. I thought I was doing it right the box resets and the lights flash, but it still won't spray past 5900rpms. Them instructions really don't say and its fustrating because I had it figured out at one time...

Below I copied the instructions for that setting it doen't tell you the dial to turn....just the # and RPM. I assumed it was the RPM dial.

Configuration:
The N2O upper RPM limit is set using this procedure.
Step 1: With the key off, select the desired upper RPM from the following table.

Dial RPM
0 5900
1 6000
2 6100
3 6200
4 6300
5 6400
6 6500
7 6600
8 6700
9 6800
A 6900
B 7000
C 7100
D 7200
E 7300
F 7400

Step 2: Set Spark Base to 8, set mode to off off off ON.

Step 3: Turn the key ON.

The Red LED will illuminate for 10 sec while the unit reconfigures.
The unit then reboots itself (Both LED's light for 1 sec)

Step 4: Reset the switches as desired. Configuration is complete.

speedo,

Take a look at my thread earlier today. Same questions that you have.

Just read it....thanks..

Can you shed some light on that Settings page? Or that wallet tuner card?

Any information that I could give you would be a guess and I don't want to give you false information, especially if it could cost you your motor. I would highly suggest talking to or e-mailing Matt at Harris Speedworks for starters.

Good Luck.
