How good is the Simple Digital Systems Extra Injector Controller?
Thats a mouth full ;)
Could i run like 20 pounds with this sucker and 4 extra 24Lbs injectors?

Bump

Corbin?

I think Corbin actually looked into that one first, and it seems really easy to use, but it did not have the range of adjustments or the windows programmable interface that the http://www.034efi.com supplemental injector controller had.

The model you're referring to, I think, would do a solid job though, and would probably be a LOT easier to play with, with less adjustment options.

Yeah, i went to Corbin website. It really great, thats what got me thinking about doing this. This one is a whole lot cheaper then the 034 ecu. I guess what i asking is if it is as good as the 034ecu in just adding fuel? I want to run 20 lbs. and keep my idle like factory. Hahns racecraft websites limits the street driven boost to 15lbs, and i think this would be a great way for me run alot of boost. Why do you guys think?

I am currently running this SDS system with 4 19 Lbs injector monted underneat the intake. For the moment I run 5 PSI (until I recieve my fuel pump). I start to put fuel in at 3 in. of vacuum (left potensiometer) and the Gain (right potentiometer) is set at 3.
As we speak (stock fuel pump, 4 extras 19 Lbs injectors, 5 PSI of boost) if I put more Gain on the SDS I can be rich enough so that A/F is all the way up and black smoke get out of the exhaust. It realy work.

I think that 20 PSI is possible with big injector, a good pump and a 1/1 FPR. I dont think that more than 23 to 25 PSI is feasable beacose of the map sensor that is in this SDS controller.

I realy like this system because I can chainge thing while I m running and immediately see the result (no computer, just two simple potentiometer to play with). It's realy easy to fine tune a fuel system with this kind of system.

Now, if this @#*$~" pump may arrive!

Thanks for the help. I like that it simple and compact too. How much boost well you run when your pump pump is install?

I'm gonna install my pump the same day it arrive, and I will complete the rewire at the same time.

This summer I will boost to 7 PSI and if money come my way, I'm rebilting the bottom end this winter.

After that, maybe 10 to 15 PSI

cool, man thanks for the info.
