Lol, I know what injector duty cycle is, I just didn't know what the acronym ment. I'm not good with acronyms. Anyways, the car is allowing me to make changes to the a/f ratio while, but very minimum. I do not know if it is injectors, but if it is, it very od because even on the graphs, it does not show up as an error or anything while plotting. It seems as if something is "blocking" or limiting my fuel flow, I hope its not a clog in my lines, but also, I honestly think it is my fuel pressure regulator.

 

Its more likely your not modifying the fuel map in the right place. Are you using caculated load or 2byte load? I assume you have a wideband for detecting changes in AFR. The old school way of finding the location to modify the fuel is to log timing, RPM, AFR and then find the timing path and the fuel path will follow the same course. Also due to WB latency and depending on where your o2 bung is located you may have to change in one place to get effect in another.

The fuel table is setup with arbitrary targets as previously mentioned. For example I have a lot of 10.3's in my fuel table under boost and my AFR is 11.5:1. If I want to be richer I lower the targets, if I want to run leaner I increase the targets. About 1.3-1.4 points of ECU target will change your AFR by 1 point.

 

Yea, I understand what you're saying, whats going on is, that when I add a tiny bit of fuel, its will but we can only add so much, my guess is that I have some defective injectors, if not a bad fuel pressure regulator... Its more of a mechanical issue than the actual tuning being an issue...

 

you may also want to disable your lean spool. this will make your logs more consistent making the tuning easier.

 

Problem found, minor boost leak (I am an idiot).

Thank you all very much for all of your help and support.
It was highly appreciated.
