If anyone has been struggling with high intake air temperatures I have designed a harness to relocate where the Tmap sensor reads intake air temperatures. The ECU now reads temperatures at the cold side intercooler pipe.
The primary benefit of relocating the TMAP sensor is **consistency** rather than outright power gains. You’ll notice fewer power drops due to heat soak, better throttle response, more stable performance and increased average MPG.
This sensor relocation kit works with any all factory and aftermarket parts and tunes. JB4 and ECU tunes included.
Expected Gains v6 3.3T
1. Improved Accuracy of Sensor Readings
- readings from the cold-side intercooler pipe provides cooler, more stable intake air temperatures, allowing the TMAP sensor to send more accurate data to the ECU.
- This can lead to better ECU decision-making for air/fuel ratios, ignition timing, and boost control, especially during sustained performance driving or in hot weather.
2. Reduced Heat-Soak Power Loss
- Heat soak in the intake manifold can cause the TMAP sensor to read artificially high intake air temperatures (IATs). This often triggers the ECU to pull timing or reduce boost to protect the engine, resulting in power loss.
- Relocating the sensor will mitigate this issue, allowing the engine to maintain more consistent power output, especially in repeated pulls or track conditions.
3. Potential for Slight Power Gains
- While the relocation itself doesn’t directly increase power, it can help the ECU optimize performance by avoiding conservative tuning strategies caused by heat-soaked sensor readings.
- In real-world driving, this translates to **5-15 HP** and **15-30 lb-ft of torque** in scenarios where heat soak would otherwise cause power loss. These gains are more noticeable in hot climates or during extended performance driving.
4. Improved Throttle Response
- With more accurate TMAP readings, the ECU can better manage boost and fueling, leading to sharper throttle response and smoother power delivery.
5. Supporting Modifications
- If you have other mods (e.g., upgraded intercooler, intake, JB4 or ECU tune), the benefits of relocating the TMAP sensor will be amplified.
