I spoke with the guy at All Out Auto that will be tuning the car. He said the driver will probably be okay. The weak link in the PMS is how it interacts with the MAF meter. He said sometimes drivability tuning can be very tricky. I'm going to get it running as good as I can and make sure everything is mechanically sound and then bring it down for a tune. It will be an all day event to tune for power and drivability.

I can't say that I really understand how this can be. I've never had to use the low impedance driver but it's my understanding they are built SPECIFICALLY to interpret min/max pulse voltages and convert commanded duration and slope to one that is compatible with the injector.
If it doesn't do that well, then it shouldn't exist. lol
My only other thoughts on that are that it should be user programmable if there is a standard of some sort (written or unwritten) that is loosely followed when manufacturing these injectors.
Am I missing something or does that about sum it up?
