Did the nozzle selector for you. You should be using 225cc/min in total. That can be done with one or in combining 2 nozzles, i dont remember what system and amount your injecting.

 

I have no idea what a CF is...
but I bought the dual nozzle setup, but the kit did NOT come with the extra nozzles so Im running a single 175cc/min injection right now until the extra nozzles (both 100cc/min) arrive. I also have the rubber chargepipe adapter fittings cming as well since the kit only came with a tap and fittings for metal chargepipes.
I used the guide in the installation booklet for mine as well. It said 175cc/min for vehicles producing ~350hp (it may have been ~300hp. I cant remember off the top of my head.

I may need to adjust the pressure on the pump as well. During the installation, I did turn the pump pressure down a little until I ran it a few times and I haven't turned it back to 150 yet. But since the nozzle is so small... even if I was running it at 100psi, Im pretty sure it'd still put out the full 175cc/min.

 

CF is the timing pull and the lines for cyl 1-4.

Thats why your still seeing pull. You pump is down to 100 when you need it at 180psi.

With just one 175cc and the pump at 180psi for 16-20psi
- actual = 303
- recommended = 342

With 2 nozzles both at 100cc and pump at 180psi
- actual 175 x 2 = 350
- recommended 342

at 21-26psi its 386


So bump up the pressure to 180psi and get it closer to what you need, not to mention better atomozation. Then add the 2 100cc/min nozzles when you get them

 

Tuning this thing and graphing it out.... buddy of mine isnt understanding why the timing is so high (25-35 BTDC) and why its constantly moving during runs..

Any info on this?

 

I dont know, hey dont you have to adjust the lambda regulation or (the amount of time it takes for your ecu to adapt) when you start ur tuning? Just a thought but I thought that I read somewhere that you had to do that. Nate does this sound right?

 

 

Yea, good call.

I meant to ask that actually. I've only been adjusting timing. Should I be adjusting fuel or air also?

 

USRT says the stage 2 pumps comes with a 180psi pump. So if you have a 150pump, your going to need slightly bigger nozzles. But that is your problem, not enough injection. Also, 1cc is 1ml. When injected at higher psi, its just like fuel injectors, you will push more fuel at 4bar fp than at 3bar. If you only have the 150psi pump, a 175cc just post ic and 100cc next to the TB, you should be good for 21-26psi.

Turn up the pump and make a few more runs, im sure you can advance timing another 1-2* or atleast get rid of the pull.

 

Yes you should be (decreasing the lambda regulation) so the ecu wont adapt itself out. I am pretty sure that is what it calls for, have you looked at this I am sure but just for reference.

Even though it may have cost me an alternator... here's the results of some of the timing runs i did yesterday after advancing the timing to 2.25* adv from 1.5*

After increasing the pressure on the pump for the W/M, it eliminated alot of the timing pull I was getting before. Now at an increase timgin advance... I am getting actually less timing pull. If it weren't for the alternator issue, I would advance it further and run it again.

This is just two timing graphs from the two TIMING runs yesterday. I also did 3 dyno runs yesterday also. I have not graphed that yet though. We'll see here shortly
