Description

The kit offers the option to include either a Walbro 460 or a Walbro 525 fuel pump to meet specific performance needs. When equipped with the flex fuel sensor option, it allows for seamless integration with your ECU for optimal fuel management. Installation of this kit necessitates wiring the flex fuel sensor to the ECU and connecting the fuel pump directly to the battery. It is intended for use with Motec or Syvecs ECUs and requires professional tuning. Lamspeed Racing states this is the same kit used in their World Record Toyota GR Yaris, which achieved a 10.5-second 1/4 mile at 131 MPH and a 1:36.8 lap time at World Time Attack 2022. Installation by a qualified mechanic is recommended.

MIA's Description
