Upon installing the JB4 the only info shown is for the C63 , the MAP sensors are not in the same location and are harder to access I could not find any info on this and luckily had some illustrations I could refer to that others won’t have ,I posted below , Burger Motorsports if your reading this you need to update your instructions , having no phone support is annoying, pretty sure 150 is map 1 and 40 is map 2, the rear map sensors have to be accessed from bottom ,I had to remove a hose on drivers side to get to map 2 , also removing the access cover on the bottom requires the support bars to be removed

Sorry to hear about the headaches! Have some photos of your engine bay so we can locate the right sensors for you? Looking at your reference it appears to be 150 and 40.

That’s why I posted them , to help the next guy, you also have to remove a hose n the passenger side to get to the # 40 ,a major pain in the ass lol
