so im about done with my single turbo set up but got a lil few questions. i was woundering about the fuel injector atomization line. do i need to hook that up or can i cap it. and if i do need to hook it up can i jus hook it up to the uim or doenst it have to be before the throttle body.
also im not gonna be runing no boost controller right now. im jus gonna be running off of my wastegate spring. so my question is can i run the the line from the wastegate to my uim or does that also have to be before the throttle body.
thanx alot

 

The majority of the people just cap it off.

 

If you are using side feed primary injectors then I would leave the atomization line connected. It's there for a reason. I have mine sourced at the compressor exit, right next to my wastegate line.

Technically you can run your wastegate line from the UIM but you should really give it a larger diameter fitting than what you find on the UIM.

 

The metal nipple on my stock twins was filled with metal welding slag and did not even work. When installing the Efini "Y" pipe is when I discovered this. The results with the new "Y" pipe was that this gave the idle more air and the rpms increased.
I had to use the AAS to decrease rpms and stabalize the idle.

With a single the only noticeable affect on mine is again the rpms. It might or might not affect idle atomization of fuel. If you have to open your throttle too much to get a stable idle and are not using the tube, then use it.

Think of the TPS movement and how it is affected by total TB movement.
If you need to have the throttle opened a lot for idle and then adjust TPS voltages to normal, then at full throttle the voltages may be low.
