This product does the job of increasing or reducing gas injection throughout the entire engine rotation. Based on the same number as normal, you can change between 5 levels for the thin one and 5 levels for the darker one. If you cant adjust it successfully, such as the injection controller made by other companies, you can fine-tune the amount of fuel injection over the entire engine rotation. Easy to install! Simply connect the + and - of the device power supply, and attach the two chassis harness to compensate for the amount of spray. However, please note that it will not work if you are using other subcons that are currently using the accelerator opening.
