Largest high impedence injectors? Who makes the largest injector that will work wihtout an impedence converter?
I have mototron 60's, but would like to go to an 80 if possible.
If not possible how do the impedence convereter's work out? who makes the good stuff?

WOW 91lbs how are those going to be to tune? That is one serious high imp. injector.
You can get 75lbers anything over the 60's are going to be difficult to tune out at idle.

I know of several people that have gotten a nice idle out of large low imp. injectors (w/o boxes), are the highs more difficult to tune for some reason?
I've heard the low imp. injectors with boxes tend to run rich at idle, would these larger 91 high imp. injectors be a better choice since that's about the size I'd want anyway?
The problem is eventually you get to the smallest pulse-width that the PCM can dial in and then the car will run rich when it sits in a fuel cell for too long.
I am speaking from my experience with an earlier version of LS1Edit and 83lb/hr injectors that I had in the car using an acceleronics impedance converter. The newer Edit, EFILive, or HP Tuners might have a way to lower this now.
The car drove perfectly fine until it started to load up...WOT tuning was a breeze, and to be honest I never spent a lot of time trying to get the idle stuff right.

Thanks Phate. Does anyone know if this has been solved?
I would just think the super large high imp. injectors would not have enough electrical current to control them. I guess we'll see in the near future.

If you want to control low impedance injectors with the stock PCM you can use a box from this guy:

The larger an injector the worse they are at this and is also why they usually are the low impedance, peak n hold electronics style. A disc style injector, such as the Lucas brand, has the best dynamic range due to the lighter weight of its disc.
