I have a question, I believe someone told me that on the newer LBZ/LMM trucks you could command whatever fuel amount you wanted, but the truck would only deliver 125mm3 at the most. (mine delivers 126mm3)

Is it the same for the LB7/LLY trucks, do they max out at 125mm3? I don't need more than that, and if I do I'll get it through pulse width and fuel pressure, I'm just curious is all. Thanks!:cheers:

I was told the same thing

thats interesting. So how exactly does the ecm determine mm3 when we start messing with pulse width and pressure? I have always wondered this? or does it really know the exact mm3?

Once the pulse width table is modified, the MM^3 value becomes a reference only.
