Bosch 42lb Green injectors maxing out around ~10psi?

if your injector constants are not right, the duty cycle will be wrong. If you're seeing duty cycle over 100% then you need to readjust the constants. This will also likely require VE table adjustments.

Forgive my ignorance, but specifically what settings need to be looked at on the constants page?

I'll post an MSQ and log later this afternoon, I need to grab my computer from the shop to look into this further. Thanks!

Yes, Gasoline. The AFR's are where they should be, even when the indicated DCs are through the roof. The fuel system is bone stock m20 stuff.

The car is pretty fast, butt dyno says 280hp or so, maybe a little more? But who knows...

post your msq and a log

Gasoline, I assume? When you "run out" of duty cycle, do your AFRs start climbing? Is your fuel pressure manifold referenced? As I'm sure you know, it's impossible to have more than 100% duty cycle.

10psi doesn't mean much, per se. The injectors you have should get you to around 325whp, I would expect. How fast does the car feel?

Does this sound right? Stock m20, HX35. MS logs are showing >100% duty cycle. I know MS calculates DC off of a variety of factors and isn't necessary accurate. I was always under the impression that those injectors are capable of quite a lot more than that...
