Will this sensor work if I'm running a tune or custom ECU map?

Engine sensor compatibility depends on your specific calibration. If you've flashed custom maps, verify sensor specs with your tuner before installing — some tunes require matched sensor ranges to run properly.

Do I need any special tools or adapters to swap this in?

This sensor uses factory connector and mounting — standard automotive hand tools are sufficient. No adapters or specialty equipment required for the physical swap.

What's the return window if this doesn't solve my issue?

Contact ModSupply customer service with your order number and issue description — they'll walk you through next steps. Keep the sensor in resalable condition if you think a return is likely.
