Does anyone know the pigtail number or a source for the 2 pin connector that plugs into the CMCV solenoid?

 

Just did some testing today. If you are putting a 2018 F150 5.0 intake manifold on a 2011 to 2014 F150 and wish to make the CMCV inoperative without spending any money, do nothing. You can leave them on. These valves are normally open and only close when the intake manifold has sufficient vacuum and the CMCV solenoid is activated.

Also, changing the water outlet (at least with my 2018 manifold) is required.

 

how exactly do you plan to activate the CMCV solenoid? Considering 11-14 doesn’t have any of that

 

If I don't want to use the CMCV, I'll just install the manifold and leave the CMCV valves electrically disconnected. Having them left in place harms nothing.

I plan to do some experimentation with an external control system that will eavesdrop on CANbus to see if I can take advantage of any of the benefits of the CMCV.

 

I think you could bypass the solenoid valve and run vacuum straight to the actuators. This would close the cmcv at idle and part throttle and open them at wot. I think that part would work right, but the spark timing, torque, and speed density Calcs would all the wrong since the gen1 doesn’t have the mapped points for imrc closed.

 

I thought about that. If necessary, the MAPS could be changed for the added CMCV functionality but I'll make some measurements to see if that is necessary. 2011 to 2014 F150's use MAF sensor instead of the MAPT sensor for 2015+. Older Ford engines employed IMRC and MAF sensors for control with a more primitive ECU.

 

Lot of work/effort for little to no benefit

 

It would take some doing…you’d have to figure out which mapped points were being used when the cmcv was closed then steal gen2 sd/torque/spark/loss data from equivalent cam angles in a gen2 cal and paste them into the equivalent mapped points in your cal. I see it as a long process that few would even be capable of doing.

 

Does anybody out there have a 2018-2020 F150 5.0 who can provide a picture of the 2 pin connector for the purge valve (it's on the drivers side of the manifold near the fuel line)? Thanks

 

Well, I finished installing the 2018 F150 5.0 intake manifold on my 2014. The vacuum actuators for the CMCV need to be removed as they hit the firewall.

I also did something a little different on the evap system. Instead of the awkward plumbing we see to make the 2014 evap work with the 2018 manifold, I installed a 2018 evap valve and made an adapter cable to connect the old evap connector to the new evap connector.
