Digital/ Engine Management About the 4A-GE 20V a single distinct element, namely the VVT (Variable Valve Timing), needs to be controlled by a sign from your ECU. Working with a regular Laptop or computer 16V product nonetheless, it truly is tricky to do. Some installations use the 16V's Computer system to run the 20V and utilize the TVIS sign to trigger the VVT. But, since the VVT shuts off to return the cams at higher rpm, Yet another "off" posture needs to be re-mapped into the pc. The height ability will not be reached by leaving the VVT in its on situation. The gas map alone is vastly different about the 20V's as a result of fantastic dissimilarities in the injector dimension.

On top of that, the 20V's ISCV (Idle Speed Management Valve) needs to be controlled through the ECU where by as it absolutely was controlled by uncomplicated cooling process temperature inside the 16V.
