Stock 2007 Z06 90% duty cycle?

[foshizl]

well, I am fairly new to tuning, so this past weekend I just drove around town doing a scan to help myself learn the VCM Scanner better. I had a couple questions and am not sure how normal this is.

My car is stock except a Haltech intake. When I went WOT the scanner is showing 90% duty cycle for the injectors. I know they are only 47lb but sheesh you wouldn't think the factory would cut it that close?

Also, just a random thought, I know that these ECM's have a max dyn cylinder value of 1.36g, typically how much boost does someone run before they hit that limit?

Thanks

You can actually go higher than that on the max airflow...the axes are configurable on the newest ECM's. I think the limit is some unreal number like 4.6.

whom ever tuned it, is pouring too much fueling, look at your fuel trim and also take a log as we can better help your curious situation.
