I can't seem to really find any extra injector controllers anywhere. Wheres a good place that sells them? The only one I can find is this one: http://www.autopartsdealer.com/sard_..._content=rank1 Any good? I'm looking to drive one addition injector to support low boost, 5psi from a t3/t04 tops.

 

here is a company it makes the spit second. I have not used it but I was going to but went with a megasquirt. You could use that but you have to do your homework its not just a plug and play but it does have some extras over the split and it would have room to grow. Split Second for the split second and Split Second for the megasquirt.

 

With the spilt second one, you need an R4 to program it, right? How much is the R4? Something that can be programmed at anytime from in the car (no laptop needed) would prob be best..

 

this is the one i use. a laptop is needed but it comes with the software to program it.

here is another option if you dont want a laptop programmable unit.

Nice, thanks. How is the F.A.C.E. unit? Any experience. I've been thinking about that one lately.

 

Also, does this unit have an internal map sensor or how does it control the rate of injection?
