Reply To: [How to Tutorial] [Bike Mod] 650/250/125 – AiS Block Off Removal (EGR Delete)
Some ECU’s might moan , as the fresh air pumped from the airbox might affect the 02 sensor readings back to the ECU. So i would caution this.
With that being said, I did have a customer 2011 Delphi bike with 2x 02 sensors (i know 2011 and a delphi?) the engine had no AIS system whatsoever not even a plug for it, it was as if Korea saw no need for this particular bike not to have it , then i had a 2008 Sentec ECU bike that had 1 AIS system feeding the rear exhaust where the lambda sensor was.
