Where are the dip switches suposed to be set on the v2 controller for #7 nozzle. And what is the output presure suposed to be? Also if rev and hold the gas at 3,000rpm and press the test button how long sould it take for the stumble to start? also is the gauge suposed to go back to zero when you let go of the button, or should it keep some pressure in the line? thanks

 

Down Up - from SMC - (Standard but strongest setting)

Output pressure should be 100+psi

3k+rpm (do you have intercooler pipes?) - 5-10 seconds

No pressure in the lines if the alky isn't sprayin

 

You can just do it at idle after the car warms up. Mine stumbles immediately when I press the test button.

Back before I changed the dipswitches, I would only get 80psi, and the car would never stumble. After flipping the one switch, I immediately got 100psi and would choke my car almost instantaneously when hitting the button.

 

+1

I use to do this before I swapped my intercooler pipes and added my AEM UEGO Wideband. It's much easier to notice if it's spraying or not.

 

Hum. Ok, I called smc they said first button up, second down. Ok withen a second of hitting the test button i get 100-110psi and a fine mist. But the car does not stall or really stumble. At 3000 rpm it stumbles a bit but takes a while to make a big impact. I did get a check engine light (to righ im guessing) when I held the buttom down to much. Im sure its working right cause I had the thing set to spray at 20psi and hit the road. The second the car hits 20psi it stops pulling and is as if I let the gas pedal up 50%. I hope imnot sounding dumb I just want to make sure my stuff is good to go for my tunning sesion with Al this weeked. thanks guys Now the only reason I can think that the alky does not drastically mess witht he motor down low that much is cause I am running 280 cams, They idle great and all but maybe thats the reason. I was expection it to feel like How when you manually turn vtec on, on a honda at real low RPM, like the car wants to stall.

 

Interesting??!! I just rechecked my email from Steve and he said that from his shop they are set to DOWN-UP?? Either way, if you are getting 100+psi I would assume you are fine. It is just settings of how much pressure the pump is going to send out.

As for the stumbling. It was never are LARGE notice. Just watch your RPMs if you are going to spray without reving the engine. It should almost be instant of seeing the RPMs rise when you press the test button. If you do rev up the engine it will take a little while for the car to bog.

As long as the system works when you push the test button . . . . . . I would leave it until Al can tune it for you. That's all I did before I got it tuned.

Good luck with the tune - let us know if you have more questions

 

Don't worry, I remember Al just tested my SMC kit at idle to see if it stumbled and said it was working fine. Not at 3000rpm per smc instruction. The important part is your seeing 100psi at the gauge when spraying.

 

Thanks fellas, makes me feel much better. Well last thing is to install forge bov and boost check to 30psi and i should be good to go. thanks again

 

i have mine set as up up from the smc. i put it to down/up and get more knock it seems. i havent looked at the psi readings though
