Water/meth in map sensor line
 

I removed my ecu today and found a small amount water/meth mixture in the map sensor line and the fitting in the ecu. Would this be caused by excess injection, inlet manifold design or the position of the map sensor source? It's set up post intercooler about 600mm from the throttle body. The inlet manifold is a forward facing design and the map sensor fitting is on the rear face of the manifold. Injectors are 6 x 750cc and I have 2 x jets in it which are either 0.8 + 0.9 or 2 x 0.9. I don't seem to be getting any ignition breakdown, even with the rich tune in it as I haven't had it redone since a cam swap and the aquamist system being installed. Boost is around the 22-23psi mark with a GTX35

Just mount the map sensor as high as you can...

The map sensor is an internal one in the ecu which is mounted in the kick panel so it will always be a lot lower. I don't really have an option to move it but is there something I can do with the routing of the vacuum hose running to it? I think there is always going to be a small amount forced in there under boost due to the plenum design

Have the line run as high as you can with a small loop introduced in it before it goes down again to the ECU.

You can always get one of these airline water trap.
