Introduction
This document outlines information regarding the Toyota Prado ECM reprogram recall (identified as GGG38). It consolidates user feedback and observations following the ECM update.
Problem
Users have reported an increase in fuel consumption after the ECM reprogram was applied. The reported increase is approximately 0.5-0.6L/100km. Some owners are concerned about the impact on the vehicle’s official ADR fuel consumption rating.
Potential contributing factors
- Vehicle Weight: The Prado’s weight (approximately 2.5 tonnes) may contribute to fuel consumption.
- Engine Size: The 2.8-litre engine may be working harder due to taller gearing.
Potential Solutions (Discussed)
- Lowering Final Drive Ratio: Altering the final drive ratio to achieve higher engine RPMs at highway speeds (e.g., 1800-2000 rpm at 100km/h) was suggested as a possible solution to improve fuel economy and drivability.
- Diff Gears: Changing diff gears was mentioned in the context of addressing both highway driving and low-range performance.
