    His complaint was specifically that it idled very rich. No matter what tables i defueled, i couldnt log lower fuel delivery. I like the idle to be at 750, as it accentuates the rumble made when vanes are commanded open at idle. It sounds like a truck and less like a hair drier. With that, the fix/bandaid was idle at 900r vs 750r ... I could defuel as needed with torque to fuel tables, just lost the rumble in the process since its 100r over the rpm i have for when the vanes start to close

    Ahh i remembered another inquiry... In Scan v8, data logging the various injections... We have 2 pilots in the ecm calibration that supposedly run but i can only log when one of them is on/off... Specific PID is IEASTAT under GM Enhanced... Is this a limitation of scan v8?

    It'll just be the PID itself, GM defined its operation not EFILive.

    The table you've shown above I don't think is a base fuel to mm3 table based on TPS for idle, I think it is fuel limiter when torque reduction is active. Obviously I can't see in HPT where you've pulled that from but is it in the Trq reduction group?

    I found it in the Main Injection params... I was attempting to defuel by reducing the torque to fuel tables, and i was not able to reduce fuel using that table. I had reduced to a value that should not have run, but continued to idle with no reductions in fuel per datalogs. I was able to get an improvement by increasing rpm to 900, which coincides with what i should be seeing per that "base qty" table. There is something that i am aware of from my experience, that the main torque to fuel tables are way wrong in the other guys software. That is the specific reason i stopped using it on the e98. It does not line up with data logs. The mm3 values are scaled in a way that the tables only show 50% of the value. Anyways that beyond the point... This particular truck, the operator complained about excessive smell, even while in the cab. He is +5000ft elevation, Baro reports 12.038psi. I was able to raise idle speed to 900rpm and there was a large improvement, but still has a lingering smell

    While not fuel related, I still would like to get the multiplier & adder tables for SOI timing.

    That is definitely fuel related, on a diesel

    in a couple of months i'm going to be adding another turbo to mine for a compound setup, so I would be happy to test/play around with vane control too if we can get them added over time.
