SPOHN'S Journal II Track Demon Reborn

SPOHN

It doesn't effect my car. I've done this on my 350Z with no issues. I think the people that had issues is because they didn't vent the proper hoses. They just sealed them all off. I'll try to get pics today. Mostly you want to put a small crank case breather filter (from K&N) on the hose that goes to the gas tank. Other than that the system works the exact same in the EVAP was installed. The EVAP is a simple air/ fume filter. All I have done is removed it and the system still operates the same.

DIY: EVAP Removal

a BIG note on this .

7AT owner should NOT do this ,
The 7AT/ECU require the EVAP setup to function properly, it might sound weird but it does and you will break the tranny over time

even if you have Uprev, 7AT owner must keep the sensors/EVAP in place.
I had a big talk on this subject about 2-3 years ago with Jared @ Uprev, when I did this Mod.

Glad you brought that up. I vaguely remember reading that.

Any details on that? I'm trying to imagine what the connection would be between the two, and drawing a blank. 7AT uses a vacuum line that's connected to the EVAP system running down the body or something? Can't be that, that would be easy to fix.

the 7AT needs a functional EVAP sensor for the proper calculation of the Calculated Load
if you deleted the EVAP setup, the 7AT will always be at 100% calculated load and this will cause an excess unnecessary wear over time.

dont get me wrong , the tranny will work the way its suppose to but with a bit less reliability

I just went into my emails with Uprev and this was on one of the last email that we exchanged on that subject.

Be careful with the EVAP removal. There is a pressure sensor as part of the EVAP system that is used in calculating barometric pressure and this affects a few different things outside of the EVAP system, like how the car calculates load. I recall seeing issues with a particular Titan which had it's EVAP (including this sensor) removed. I don't remember exactly what fix was done for that particular vehicle(Jared would probably know better), but if your sensor is currently removed, it would probably be better to wire it up just reading atmospheric pressure.
