    S550 Steady State road tuning

    Hey Folks,

    I have a 2018 GT350R with a Nitrous Outlet plate kit on it. Other than the Nitrous kit, the car is bone stock. Now that the nitrous plate is installed, I want to make sure that the MAF calibration and Speed density system are as accurate as possible prior to getting into the nitrous. I have the a histogram setup for long and short term fuel trims at a specific mass airflow period. The problem I'm encountering is that when I left foot brake in this car to try and smoothly change the engine load after 3-5 seconds the electronic throttle closes. I found a brake override under the electronic throttle tab, but that just appears to disable ETC wrench light. Anybody have experience with this?

    Solved. Un-hooked the traction control. That's embarrassing.
