Looked at the dominator and the Fueltech systems, both of them would have been well over 2k and I would have to build the harness. I got a gold box, a micro trans controller, and harness for less that I could have bought the aftermarket box. Put a leash street strip board in, and the whole thing fired up perfect with no fuss. I had carb and injected motors that took more to get running.
What do you guys recommend for one step bigger injector then the deka 80's that aren't crazy priced and work well with the microsquirt? Something in the 100-160 range.
None that I’m aware of for pump gas. The only cheapish HI-Z injectors I know of bigger than the common 80’s are the Bosch 210lb deals. Around $65 each. I’m not sure batch firing those would work well. (it might) I tuned a set on e85 with an MS3x no problem on seq. fire. Didn’t try batch firing.
All the other cheap 100-160lb injectors I know of are low-z and need an injector box. I batch fired some low-z 120’s no problem on e85 with an injector driver. Not sure I could have gotten them to idle on pump gas.
How much injector you need? For About $560 you could buy 4 210lb injectors and another micro squirt to run them. Basically the same cost as a set of cheap low-z 160lb injectors, and you could add another 8 if you wanted.
Set it up kinda like this on the charge pipe.

That actually doesn't seem like a bad idea do to my circumstances. Non intercooled on E85 with gen4 5.3 SBE and sxe 66/73's looking for 850-900whp. 8 Siemens 80 deka's in the intake and another 4 deka 80's in the charge pipe to cool the inlet temps. The additional micro and 4 80's will probably run me 450$
since they would be a group and not individualized in a cylinder where matched flows are important, you could do the uncapped flex fuel injector thing fairly easily.

2 210s would flow more... one at each turbo inlet maybe? You can phase them in at higher boost levels. Turbo would help atomize.

That would work too. How would the second ECU tie into the first ecu? I am most likely having Shannon Taylor build my harness so if the second ecu needed to tie into the first I would need to make that decision beforehand I purchase anything.
If you can tie them it woudl be over teh CANbus stuff and I haven't played with that at all. Most Likely would have to be independent of each other. Which would make tuning more of a chore. With the MS3 you can set it up as staged injection, I'm not familiar enough with the micro to know if staged injection is possible. Could always sell teh single micro setup you have now and move up to the MS3 base.
Cheap budget ecu's can have their place...but will always have limitations too.
At some point you need to upgrade or spend some money somewhere.
With the Micro having only 2 injector outputs, I would be very surprised if it can do staged, as it would mean 8 injectors wired to a single output.
We were talking about buying an additional $300 micro to control 2 additional injectors. It would work fine. But connecting the 2 micros over the CAN bus and getting them to talk to each other for a staged setup might be asking too much. It think it would have to operate independent like the old piggy back ECU’s.

Given main triggers are hall effect, crank/cam can easily be paired into both ecu's
Only sensors that are not happy are 2 wire resistive types, although that's partly due to internal pullups used
If it was just a piggyback to run injectors higher up...you could forego any temp related stuff.
But it would be a very messy way of doing things and make tuning more awkward.
Just buy an ecu that can do it all with one box. As said, there has to come a point where trying to do everything dirt cheap is just stupid and counterproductive.
Likewise on the cheap....you could add a second row of injectors and just trigger them off a pressure switch/relay. The transition would be messy and tuning more awkward, but it would be a little cheaper aside from additional injector/fuel rail costs.
There are lots of messy ways things can be done, always best to do it right though.
Originally the question was what injector would work well that is bigger then deka 80's and still be able to be controlled by the micro. I think a good set of FID 120's would be cheaper and obviously a lot easier then adding another micro with more injectors in the charge pipe.

I agree, I always get hung up on trying something new. What do those 120’s cost? I thought anything larger than the 80’s in a HI-Z was pretty expensive until you got to the huge 210lb CNG stuff. I see FIC sells a HI-z 160 now as well, but they don’t list a price on their site so I assumed the worst.

The 1000cc is 690 and the 1200cc is 860. Not too bad of a price. I'm not sure if FIC is cheaper

But any will be trial and error to see how well they do work too.
I guess another question...just how much more fuel do you need ?
I flushed my fuel system today of e60 with pump gas. I'm running 1700 cc's of injector Runs greet full sequential so I switched it to batch fire. PW went up just s little and idled at 14ish afr with no troubles
