Description
BT MOTO IAT RELOCATION KIT
As many of our customers know, our IAT (Intake Air Temperature) Kit for the 10-19 BMW S1000RR has been extremely popular and shows noticeable gains on the street and even dyno. This IAT strategy was first used by Dinan (BMW) in the 1990's. However, the 2020 S1000RR/R/X/M included some serious changes and required a new strategy for this project.
Our kits have been installed and successfully tested with positive reviews on the street and track! The bike doesn’t feel as lazy from a dead stop anymore. The IAT Kit allows for consistent power at all RPMs and gears instead of waiting for higher gears to get additional, rated power. During our testing on the dyno and per gear / per RPM datalogging, we found many delays in the factory ignition to combat the heat soak the factory airbox flappers create (flapper removal Click Here). With our flapper delete and relocated IAT sensor, the bike reacted sharp from a dead stop and in lower gears / speeds (pre-6000 RPM cruising) without knock detection. It is recommended that the IAT and flapper removal are used together but not required.
Getting a true ambient temperature from the front of the bike is much better than getting temperature readings from its original location on top of the engine with the flapper doors shut. Idling at the starting line, pits or at a street light on a 100 degree day will put the bike into a temperature protect mode and pull power out to "save itself" until the IAT sensor reads accurate ambient air temp once the bike starts moving. True ambient temps help the bike deliver more power and stay consistent in racing conditions. We are not tricking the sensor but simply allowing it to read proper temperatures of the outside air.
WHAT DOES THIS KIT DO?
-
- Relocates the Intake Air Temp (IAT) sensor.
- Moves the IAT sensor from the factory location near the cylinder head to the front of the bike to get a true ambient reading.
- A true ambient reading means more power but also means consistent power.
- Noticeable improvements in stop-and-go traffic, starting a race from a stop and exiting the pit.
- No downside and dyno proven gains across the powerband (see dyno chart below).

Dyno Testing
DYNO PROVEN
IAT 110F vs. 60F test with and without removing airbox flaps and IAT relocation (tested on a 55F ambient day). Bike used was a 2020 S1000RR using our stage 1 flash with exhaust and 93 octane fuel on all runs.
As noted previously, the 2020 has airbox flappers that stay mostly shut, feeding no fresh air and heat soaking the bike’s airbox below 6000RPM. The stock calibration has compensated as a result. This is a back to back run after only relocating the IAT to the nose of the bike instead of its standard location. This is much different than previous years ECU strategy. We converted it back to previous years strategy to optimize performance. With this kit installed, it's mandatory to run our Stage 2 Flash for smooth performance.
As you can see both runs, before and after IAT install, have the same exact AFR (air/fuel ratio). It’s a common misconception that IAT modifications adjust fuel. They do not do that. This bike is fully closed loop and hits our commanded lambda target every time due to BMW's OEM wideband oxygen sensor technology. You can see pretty steady HP gains across the entire RPM range. Converting it very similarly to a 2015-2016 style S1000RR airbox (derestricted years). While the dyno graphs show gains, results on the street or track are actually better when you are hitting higher speeds and it creates a more noticeable ram-air effect.
- RED = STOCK - 194WHP / 87WTQ
- BLUE = STAGE 2 PUMP GAS - 202WHP / 90WTQ
- GREEN = STAGE 2 MR12 - 212WHP / 94WTQ
**Testing performed with 93 octane pump gas. Usage of a lower octane will yield lower overall power.**
