Look at this ATI owners!!
Look at this ATI owners!! Ive been working away in my shop all winter and i finally have my ATI setup done, Super custom. Just took it out last night and it works awesome
I have an extra fog light switch on the dash to turn my blower air flow valve on and off so i can choose between FI (for killing imports) or NA for just plan driving. It really cuts down on the engine wear when you can turn the blower airflow off. Im using a carroll supercharging Superfueler with 3 Aux. 42lbs. injectors before the throttle body for extra fuel. . I might start selling this kit if anybodys interested.
It works very well <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
I will have pictures once i get a new digital camera. the whole thing is made out of anodized billet machined aluminum. there is no boost loss using this valve.

Re: Look at this ATI owners!! Interesting....
I was thinking of doing something similar with a piggy back PCM system called Perfect Power www.perfectpower.com. It lets you run 3 different configs on top of your PCM with a toggle and it drives several more injectors. I'd have to run something like yours to divert the FI and go to NA. A tuning shop has been working with it here in Denver but I don't want to be the guinea pig. I decided to just go with Edit and large injectors and have the FI power at all times. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
The ultimate setup would be a supercharger that has a clutch similar to AC so you can turn it off/on and have multiple configs in your PCM. The Sy/Ty's have the Ultimate chip which is similar for their turbo setups.

Re: Look at this ATI owners!! I don't understand the idea here.
First, the blow off valve pretty much already does this for you until you hit it.
Second, your tune would be totally off if you always just shot the boost out a blow off valve.
Maybe I'm missing something.

I am confused about the switch for the bypass valve though. As you said, the bypass valve is usually open unless you give it enough throttle to transition into boost. I don't see any benifits to a manual control for it.

Re: Look at this ATI owners!! INTMD8,
I understand your point, but I was thinking of something else. The MAF maxes out on these FI setups, so you end up tuning wide open throttle past the max MAF metering point with PE vs RPM. If you ran in a pure boost bypass mode, the PCM would be adding way to much fuel at the higher WOT RPMs and your car would run like crap.
I guess it would be ok if you stayed out of WOT, but like we both said, that is pretty much the behavior of the stock BOV (making the entire idea pointless). I think his idea is to run the car however you want without worrying about the risks of boost. I’ve seen some Ford ECU setups where you can toggle between programs, but never anything like that on an LS1. It would actually be pretty cool if you had something like that.

Re: Look at this ATI owners!! I realize that fueling is added in PE vs RPM when the MAF maxes. (I've tuned many such combinations).
But when the bypass valve is open, it won't max out the maf. So you still may be able to go WOT without it flooding out.
I can't say I've ever tried it though, so I'm not really sure what would happen.

Re: Look at this ATI owners!! I'm not 100% sure on this, but it seems that the PE RPM multipliers don't care what the MAF signal says. Although the base calculations accuracy would benefit from the correctness of the MAF frequency, it would be obliterated by the over compensated multipliers entered for the MAF maxed RPMs. You're right though, I guess you never know until you try it. It would also depend on how aggressively boosted the car was.
Whoops sorry, I just read the post again. I did not notice that he is doing boosted fueling with extra injectors. Now I see. Intresting!

Re: Look at this ATI owners!! I like to keep my foot in it all the times! The tune works perfect with the aux injectors. I will have pics in a month or so. Dont want to give anything away.
Re: Look at this ATI owners!! i love it when people go out on their own and develop new things for ls1's and fi but i have to be honest here and say that i dont understand WHY on any of the above.
our intakes are not made to mix fuel, it will puddle and your per cylinder a/f will never be consistent. aux. injectors are just not the way to go to get a tune that is closer than ballpark.
manually opening the surge valve is just a waste.. the torque draw on the motor from driving the supercharger is allmost identical so all you are doing is wearing your sc as normal but not getting any of the beneifits you paid 5k+ for and losing mileage
you dont need fi to kill imports either
you paid all this cash for a supercharger, why would you ever want to be wide open without boost?
maybe you should get some nawwszz or something more suited to temporary use and save a few grand.
post caught me wrong, hope i made some points though.
