Default low impedance injectors

who's running them and did you have to do anytihng non-standard to get them to work? I'm shipping a set of 440cc supra black tops out to be cleaned this week, and will be installing them when i do my turbo install.

my plan is to beef up the MS grounding according to Jerry's recommendations, by running several 18-20ga wires from the MS ground pins to the location that the stock ECU grounds on the block. I'll leave the stock ECU grounding alone (since i'm using a kingofleet side-by-side setup for MS) and possibly may try to insulate the MS case from the body, as i had heard some things about DSM folks having issues with MS due to the MS case grounding out by being bolted to the body of the car.

any other suggestions?

btw, i know this has been covered somewhat in other posts, but i'm hoping to get a easily searchable post for future people to find for info on the subject, as well as post my results and whatnot.

from what i've found, it looks like running a proper set of ground wires from all of MS's ground pins should take care of it, as the issue others have experienced is likely due to insufficient grounding (low-z injectors will pull a significant amount more current through than the stock high-z injectors, and the stock wiring may not be sufficient).

I have low impedence injectors and as of what I have read, I need a DSM "injector resistor box". At least that is how you had to do it on a Neon.

That's a totally different way to go about it-- and yes it will work just fine and you can treat them like hi-z injectors this way.

What Devin Mac is after though is directly running the Low-z injectors via the MS's PWM control of them, without a resistor pack.

I'm looking to do the same, actually with DSM 450 injectors. Let me know what you find devin, if I need to run ground wires I will.
