Your OEM PCM has injector outputs that are matched to what is known as high-impedence or High Z injectors. As they become physically larger, their internals do as well, and they need more power to cycle. Low impedence injectors fills this void. Your stock PCM cannot supply the current for them without a driver box. As of right now, these are about as big as you can get staying high-Z.

Well I finally got everything going. Here is a log of the 79# injectors, it's in EFILive. The afr will be off since i am using E-85 and have a custom Pid for my LM1. They are running real lean, not sure why, but it leaves the idle a bit choppy.

It just dawned on me, part of the problem may be my intake, it got so cold here that some of the areas where the bolts go through cracked. I wont know until I get a stock throttle body and put on the stock intake.

It would seem that they are not as efficient as the 42's I had. I had to add 25% then another 25% to the voltage adjust table at idle. And lots of adjustment all over the table. Now I just need to get the idle under control, it's way to high. And acording to my math, with the altitude adjustment then the E-85 increase, I am using only 4% more fuel then someone at sea level.

I'm very interested in what you are doing. I want to try running e85 some day. I just don't want to give up the driveability I have now with the mototron 60's. I am already maxing them out on my racegas tune.
Keep posting your results! Are you going to up the boost & see what you can get out of these injectors?
I will be in your area this summer with my car.
