I'm on the way to correcting some of the issues in the tuning I've found after downloading a custom tuned file from a reputable company. My truck is a 2013 with a 2019 turbo on it. The previous tuner created a tune to address the upgrade. After exploring different tables, I discovered he copied and pasted the wrong part of the Boost Control tables which limited the boost to 20-21psi. He grabbed the negative torque columns and just past them over to the 0+ columns in the 2013 file. I'm guessing the the negative torque values in the driver demand and other tables address the exhaust brake in the 2015+ models. I also saw a post from @JaegerWrenching from a few years back that had a more refined Lambda/Dynamic Lambda table. I put that into the tune as well. Between the two, it smoothed things out and the peak boost shot up to around 25-27psi. My current goal is fixing a condition off idle from a dead stop. This occurs before the turbo lights up and there is a horrible pinging sound for a second or two until there's boost. What's the best way to tune that out??? Using the Torque-to-fuel tables and lowering the fuel mass in the sub 1400RPM range at higher torque, revise driver demand tables in the same RPM range to limit torque at higher throttle positions, adjust timing or is there a combination of things?? It only seems to be a problem in the 50-100% throttle position from a dead stop.
