anybody checked this out yet? http://www.sdsefi.com/eic.html i was thinking about trying this out in my next turbo setup because i didnt like the results of bigger injectors with SAFC(mostly becuase of timing issues)on my old 7g. the guys on turbosaturn.net have used it and they say it works pretty good.
Why not just add a Walbro 255 and some large ass DSM injectors?? This is useless and expected on a saturn. :? Plenty of people use those and the SAFC, get some adjustable cam gears and you should be able to work on the timing...or go with the Greddy fuel timing system.

because this would be a simple to install and tune, my stock fuel pump will be fine under mild boost and when driving off boost the stock fuel system would be left alone to do its job, it would run better and get better gas milage. like i said ive done that before and didnt like the way it ran, the safc jacked the timing up and every since i put it in with the injectors it didnt run as good off boost and got bad milage. cam gears or gear in my case is not gonna help timing because its DIS. i dont like piggy backs and would like a standalone but thats too much money and tuning right now. i was wondering if anyone had tried it on a mitsu and what their results were, not saying that one is better than the other because i have no experience with the additional injector setup.
that system doesnt seem to be a solution to your problem i mean yah it would solve the timing issue that the afc causes but its not that big of a deal if your gonna switch why not go to the greddy emanage it also controls sub injectors and alot more that system you posted was something like 360 just for the controller. if your running mild boost is the timing trouble really that major

what ecu are you going to be using, and what sized injectors?
maybe a greddy unit or something similar, i read into it a little more and there were some drivability issues with the sds unit because of over fueling in the midrange. the greddy unit has rpm adjustable points instead of just one adjustment like the sds. not sure on the injectors, probably two fairly large ones if i even decide to try this setup, like i said im just looking into it right now and trying to get some feedback
I'd recommend just getting DSM injectors, a resistor pack, and a 2G ECU...
Technically you wouldn't even need a piggy back.
well i have an 8g now so a 2g ecu is probably out of the question, so what are you running on yours and how does it run
Ahhh gotcha. I just assumed you got another 7G.
A buddy of mine in PR once went to a junk yard and pulled some stuff and pulled injectors from a mustang. Then he came back and swapped out his for the mustangs and boy did the gas gauge dropped everytime he stepped on the gas after about 2 miles of testing we came back and swapped it back in for the stock injectors but still want to use those mustang injectors. So he had the crazy idea to just had 2 of the injectors to his intake (a ghetto nitrous setup) and connected to his old fog lights switch. It actually worked but how much HP he was gaining I had no idea.
He had a 98 Hyundai Accent (2 door hatch), I have no idea which mustang the injectors came from. He got rid of the accent and now has a Mazda 3.

i think spraying the extra injectors will just run an overly rich fuel mixture.

^im with stupid.
thats just a plain retarded idea......did he have a homemade supercharger too?

haha no, but if he could have made it he would have.

i think im gonna give this one a try http://www.034motorsport.com/034SupECU.html with a budget kit from www.tearstone.com. ill let you know how it turns out

why not go the easy and proven route? bigger injectors with tuning. you need tuning anyways with a turbo setup.

Stop trying to care Peano, I did, and I feel great!

yeah the only time you need secondary injectors is for high HP/high boost applications. example, RX7's are notorious for running secondary injectors. What happens is you have your regular 4 injectors, in vacuum and low boost the 4 injectors give enough fuel, once the car starts boosting higher, the secondary injectors are activated to add more fuel with the extra boost. I know of 2 people with EVO's doing the same thing, they run 2 seperate fuel rails, a walbro 255 pump in the tank, and 2 walbro inline pumps (one to feed each rail), 8, 720cc injectors. 4 of the injectors are on all the time and the other 4 only turn on after 20psi of boost.

Wow I need pics of that 4-720, +1 = 4x900cc +2 = 4x1180cc, and +4 = 4 1440cc injectors, and that is just too much fuel for any boost application I can fathom!!! Why not just run 1660 primaries and then a few 440 secondaries if you need them...that should get you up to about 800whp

has anyone tried this on our cars? no. i have done the easy and proven route before, and i didnt like it. yes it works, it works pretty good actually, but its not optimal. piggy backs that alter the airflow signal tend to srew the stock timing and fuel mapps up off boost. the stock ecu has been programed from the factory to give the best fuel milage and runability in a varity of conditions, unboosted that is, us small timer tuners cannot improve much on what a team of engineers spent ass loads of time fine tuning, with out sacrificing some drivability or other side effects. what i want to do is what like stewi described with the evos, add fuel when the stock system runs out(which is when boost hits in our case). im goin to use the injectors in the intake setup like ripps at first with low boost (around 7lbs) and without modding the airflow signal like an SAFC, timing should be ok at that boost level. later on im gonna add the second rail with more boost and some sort timing managment. i have even seem people run the secondary rail/pump off of a seperate tank of race fuel, so you only burn the expensive stuff when youre are boostin. and when off boost it will run and idle like stock, get the same milage, and pass emissions testing.why not go the easy and proven route? why not just buy bigger injectors with tuning. you need tuning anyways with a turbo setup.
I was thinking of doing something similiar as well. Decided to forgo the idea since I had/have plenty of other stuff too worry about.
