COS 3 not responding to VE map changes

I'm running an LR4 4.8 with SD 80lb injectors at 58psi with a referenced fpr , LS6 manifold and stock camaro exhaust manifolds. I just put COS 3 on it and failed the MAF and unplugged it. It was idling in the 10s and after I removed about 45% from all cells associated with idle the best I can get is mid 11s. The car cruises at 14.7 and WOT is 12.5 to 13. The 105 kpa column responded to the changes I made as it was initially in the 11s at WOT. I would think even if the injector data I'm using was wrong a 45% change would do more. Am I missing something? Also, is there a different pid list I should use for auto building a VE table with the MAF out of the picture? It's telling me I should be using values that I know aren't sane like 0.050 @ 3000rpm and 105kpa. Any help I get would be greatly appreciated. I need to get issues like this ironed out before I put the turbo on the car. Thanks in advance.Attachment 16946

In C6001 you have P0103 set to 2-Trips... set it to 1-Trip and verify that at MAF DTC triggers immediately.

BTW:

A0001, A0002, A0012, A0013 are out-of-range...

set them to in-range values...

there's a little quirk in the tunetool that only saves the file if the displayed cell values have changed...
so to set those cells to in-range values, do this:
- set them to max-1,
- save file,
- exit tunetool,
- restart tunetool,
- set those to max,
- save file.

Is your FPR manifold referenced...?

What injectors are you using...?

You aren't going into SD mode straight away.
Set C2904 to 1, so that the DTC triggers the first time you are out of range. Then put your VE table back to where it was.

Since you have the MIL turned on for P0102 , in C6002, you will be able to see the engine light come on to confirm the MAF has failed.

I'm using Siemens Deka 80lb injectors and my fuel pressure regulator is manifold refrenced. I'm running 58 psi of fuel pressure.

I changed the tables that you both mentioned and fixed the out or range tables but it's still idling in the 10s. I also verified that it is throwing a dtc for the MAF. Any suggestions?

58 psi measured with reference hose temporarily removed...?

Log IBPW & make sure it isn,t flat lining at a set value. If it is make sure you lower B9021. (If you haven't got this parameter get it from the cax section)
