This past summer I was a beta tester for 'roger 04 rt' as he developed the BMW-AF-XIED with nightrider.com for the F800. You can read about the beta in this thread, Wideband O2 Sensor for F800S/GS. Along the way I recorded a lot of data with a GS-911 and examined a number of things in service of the beta. As part of the test I used a couple of different intake air temp modifiers. Primarily a Booster Plug put also briefly an IICE Air. Using the following as my understanding of the settings for the IICE Air, I wanted to share some findings for the IICE Air installed on a 2010 F800GS. The short story is none of the jumper settings matched the intents. Using a GS-911 to record data, here are the readings for the Intake Air measurement. For all settings taken with an ambient temperature of 30.5C: jumper in the 'no change' position - Intake Air reads 32.25C jumper in the '-10C' position - Intake Air reads 41.25C jumper in the '-20C' position - Intake Air reads 32.25C jumper in the '-30C' position - Intake Air reads 24.75C jumper removed completely - Intake Air reads 20.25C For comparison, with BoosterPlug installed, Intake Air read 8.25C. Has anyone else seen this type of results on other F800 setups?
