Is there a way to adjust this? I posted some screen shots of my log and they are sayi g that there is no way I'm seeing 1.8+ g/cyl for my mods. Just courious

If you are running 20 psi of boost
I don't see any thing wrong if your G/Cyl is 1.8

I'm running 12-13 psi on a fbo lq4. From what I've read heads would drop about 1-2 psi, cam about 2-3 psi, tbss intake with 90mm the 1-2 psi, lt headers catless ypipe and 4" exhaust would be about 1-2. So I it was stock it would be about 17-18 psi

Also, on the screenshot that I posted, the IDC is between +/-3% between the banks. What would cause this?

6.0L LQ4 = 0.75L per cylinder.
Nominal weight of air = 1.2gm/Lt.
So the theoretical maximum weight is 0.75 x 1.2gm = 0.9gm/Cyl. (Normally Aspirated)
You're running a MAP of 143kPa, so approx 43% over barometric pressure..
0.9 x 1.43 = 1.3gm/Cyl
So the theoretical maximum is 1.3gm/Cyl.
In the ECM, the gm/Cyl is a calculation off the VVE. IE, if you set the VVE high, the reported gm/Cyl is also high, set the VVE low and the gm/Cyl is low. The thing is though, that if you are running a MAF, the fuel metering is governed by the MAF table so overall fueling can still be correct even with the VVE being off.
In your case, the ECM is commanding 11.5 but your LC1 is reporting 10.68, so nearly a full point richer than commanded . I'm going to guess that the fueling is off a bit and the VVE is set for too much air flow. To complicate things, if you don't have the correct injector settings and adjust the VVE to compensate, then the reported gm/Cyl is never going to be right.

I was going to say, I think that's just what the VE table is saying the g/cyl should be, which is probably not representative of the actual airflow. As stated, if the injector settings are off, such as B3701 or the IFR table, then VE table has to compensate and will not represent actual airflow. Could be wrong but that's how I understand it. My VE table is much lower than stock because I think my injector settings are bogus. But if in the end the AFR is what I'm commanded then whatever.

Okay. Thanks for the info. My injector tables are set to the info that FIC sent when I got their 1000cc injectors. I'm still tuning the wot. It keeps going rich especially in the 6500-6900 range. I've been messing with my meth controller to help fine tune the spray.

And the highest map I've seen is 181kpa and 2.53g/cyl at 6600 rpm but the afr went to 9.93 and went into rep mode
