Gas Pedal Delay

BGTV8

Folks, there are 2 separate issues here and they are clearly confused.

1. The yaw sensor cuts throttle when it sees enough yaw-based G to convince itself that the car is about to slide, when in point of fact the car has a heap of grip remaining. This is especially noticeable on the track when trail braking hard and deep and will most likely pitch the car to the outside of the corner being entered, which is exacly what you do not want. Fixing this is simple - see here ...

2. The gas pedal deal from low-speeds is the ECU cutting fuel/spark on the basis of under bonnet inlet air temperatures. One of our AU guys in Sydney has researched this and you can find the details here ...

Bottom line is that the standard ECU simply will not give you good throttle response at low speed in even moderate ambient temps based in air temps in the intake tract and the Nissan Engineering requirement to minimize emissions, rather than optimize throttle response (at high ambient inlet tract temps and low vehicle speeds, it is simple to give the car too much fuel which increases emissions).

If you guarantee cool air input temps at slow vehicle speed, then you can tune this out but it won't be simple to engineer a solution for all circumstances and you may create circumstances where passing an annual emissions check could be a problem.
