I have the air fuel ratio gauge fitted to my KTM 390 Duke. I also have the Fuel X Pro fitted. The Fuel X Pro has 10 maps for tuning the bike once modifications have been made. The Lambdaking Air Fuel Ratio gauge accurately displays the AFR while I'm riding. I placed the 02 sensor 14 inches from the exhaust port. Map 3 on the Fuel X Pro is the factory setting for the 390 Duke. I have modified the air inlet and exhaust, I find map 6 gives me the best AFR for those modifications. If I didn't have the Lambdaking AFR gauge I would only be guessing. I am so please with, thank you.
I had concerns my engine was running rich. Put the o2 sensor in the exhaust and went for a drive. Got immediate results and peace of mind that the tuning is spot on. Highly recommend.
Idk wat i think of it mate as got wrong one first time sent it back upgraded and even express shipping and still hsvent seen noting an that was well over week ago
Hello Jack! Is is probably worth mentioning that you 'got the wrong one' because your wife originally ordered the incorrect device. The 2-channel you sent back arrived back here on Friday, so we will be dispatching the replacement 4-channel device on the next shipping run just as I promised.
