Default CMCV Delete Plate install (with pics)

Steeda (Ford Racing) Charge Motion Control Valve delete plate installation

I obtained these delete plates from Tillman Speed at a great price. CR is a stand up guy and will get you the best price he can. I recommend using Tillman Speed as the premier source for these delete plates.

First, let’s some of these acronyms out of the way.
CMCV (Charge Motion Control Valve) Delete
CMDP (Charge Motion Delete Plates)
CMRC (Charge Motion Runner Controls) Delete
… are pretty much the same thing.

Before beginning this installation, you must already have a tune that compensates for the CMDP’s. If you don’t, you will get a Check Engine light or worse, the car will go into Fail Safe Mode.

CMDP’s out from the box. They are identical to the OEM CMCV’s with the exception of the valves.
Note: Each delete runner is marked ‘L’ or ‘R’; just like the OEM runners.

Baseline pictures

Passenger side

Drivers side

1. Disconnect the ‘negative’ side of the battery. Why? It’s especially important to cut battery power when unplugging and plugging back in electrical connections to eliminate any electrical surges. It’s just safe to do and only takes 15 seconds.

2. If you have the means, use compressed air to blow the area of the intake to remove any dirt and debris. If unable to blow the area clean, use caution when removing the intake manifold to avoid any debris from falling into the intake ports of the heads.

Picture note: I was installing the underdrive pulleys at the same time, so that’s why you see additional parts in the engine bay removed.

3. If you haven’t already done so, remove the factory airbox or CAI.

Note: Don’t forget to unplug the Mass Air Flow Sensor from the intake air tube by sliding the red lock lever back.

4. Disconnect the all the electrical connections to the throttle body and intake manifold.

Throttle Position Sensor – slide the red lock lever back

Electronic Throttle Body Electrical Controller – slide the red lock lever back

Electrical plug from the Drivers side fuel rail – press the lock lever down to release

Electrical plug from the rear of the Charge Motion Control Valve (near the firewall) – lift up on the lock lever to release

Fuel injector electrical connectors (4 each side) – press the lock lever down to release

5. Lift off the circular wire bundle support clips off from the fuel rail studs, both sides.

6. Remove the 2 vacuum lines from the front Drivers side of the intake.

For the upper line (the one with the white clip), grasp the connector and twist off the vacuum hose.

For the lower line, slide the green release lever to the side and pull to disconnect. If you can’t get the angle to pull it off, you can disconnect it from the camcover, then unclip it from the intake.

7. Remove the 4 studs that attach the fuel rail to the manifold (2 each side, reference step 5).

8. Lift off the fuel rails. Grasp each end of the fuel rail and firmly pull straight up. All 4 injectors will pop up from the Charge Motion Plate.

Carefully lift the Passenger side fuel rail (with injectors attached) up and over to the Drivers side, then move both fuel rails clear of the intake manifold. I laid some clean rags over the injectors to protect them.

9. Remove the 10 bolts that hold the manifold down (5 each side). The bolts are fairly long in length.

Note: The rear Drivers side bolt is actually a stud. Remove it the same way as the other bolts.

Note: There’re 2 hidden bolts (1 each side) towards the center of the manifold, which are located under the fuel line that connected the 2 fuel rails together. Once completely loose, a magnet retrieval tool will aid in lifting it out from in-between the runners.

10. Disconnect the vacuum hose from the rear of the Charge Motion assembly from the T-fitting.

11. Not mentioned anywhere is this push-in fastener that supports a wire harness that's attached to the Charge Motion motor bracket (passenger side). It's a pain to pull out; needle nose pliers will help.

12. The intake manifold is ready to be removed. Carefully lift the manifold out and set it upside down on a workbench (or equivalent).

13. I put some tape over the intake ports to eliminate any chances of dirt or debris from falling into the intake ports.

14. Remove the 3 silver bolts that hold the Charge Motion motor to the back of the intake manifold.

15. Using a #30 Torx bit, remove the 4 screws (2 on each plate) that attach the plate to the manifold.

16. Remove the whole motor and 2 plates as one unit and set aside.
Clean off and lay the new delete plates next to the OEM plates (take note of the L/R stampings)
Carefully lift up each green seal and install into the new plate one at a time.

17. Once all the green seals are in place, I cleaned off the opposite side once more before placing the delete plate back on the manifold.
Even with the 2 Torx screws back in, there's considerable movement of the plates. Do your best to align all the injector hole openings to that from the manifold as well as the mounting holes.
I tightened down the Torx screws until I felt the seals compress onto the manifold. Careful not to over tighten them.

Just for kicks, I tacked down a Sacagewea Dollar coin on top of the block for fun, Eagle side up, of course. I can honestly say now, no matter what happens to my engine, it'll always be worth a buck!

Yes, I am the Manifold King.

18. Remove the protective tape from step 13 and clean off the mating surface of the block. I used brake cleaner to remove any oil and fuel residues. Make sure the surface is dry before putting the manifold back on. I'm not sure how the green seals will react to the brake cleaner (nor do I want to find out).

Note: I chose to leave off the Charge Motion motor altogether since Doug's tune deactivates it.

Note: Since the motor electrical plug is no longer used, I zip tied it to the conduit against the firewall.

Carefully lower the manifold back on top of the block.

19. Once the manifold is in position, drop the mounting bolts in place and snug them up.
Follow the proper torque sequence and torque them to 89 lb-in.
Thanks to my brother-in-law, Kevin and buddy, Leo, for giving me a hand in torquing the bolts down as my lower back was killing me at this point.

20. Re-install the fuel rails and push the injectors back down into the manifold/delete plate.

21. Re-connect all the electrical plugs removed from step 4 and vacuum hoses from steps 6 and 10. Also, re-install the factory airbox (or CAI).

22. Re-attach the Negative battery terminal and flash the PCM with the new tune.

23. Before starting the engine, ensure you have all the electrical connectors and vacuum lines plugged back in. Clear the engine bay of any tools and rags before starting.

Note: Let it idle while you inspect each injector for fuel leaks or any other issues. If there's an issue, shut down the engine immediately and fix the issue.

Note: Make sure you don't have a Check Engine light either. If you do, go over all the electrical connections and vacuum lines to make sure they're positively engaged. Last possible cause could be the tune, in which case I would attempt to re-flash the PCM.

Installation complete!

Undoubtedly the best write up of this installation I have ever seen...THANK YOU. Makes one feel as though they could run out to the driveway and knock it out no problem....
Understand that you did the UD Pulleys at the same time, but will be anxious to hear your impression of this mod, since most of the reviews are somewhat mixed.....

Thanks for a super document.

I am thinking about these plates as well. Are they worth the $ and trouble of install or is it not that noticable? How about the pulley's, what are the pros and cons of that? Regardless, awesome detail to attention in your fantastic write-up.

Thanks everyone. [8D]

I'll try and answer the questions asked.

Time: Total time was creeping up on 5 hours. That included the UPD install, taking time to take pics, and a pizza lunch break.

SOTP Feel: I'm afraid no one can subjectively say that they 'feel' an improvement or not with them. However, Doug has dyno doucuments on his personal 05 Auto that did show an increase in both HP and TQ.
Here's what Doug said about them.. "The results I've gotten from them were 6rwhp and nearly 10 rwtq overall but in the mid range gains of 7-9 rwhp and 8-10 rwtq from 3000 rpm's and up... I drove it and it is truly hard to say if I could feel any difference at all, I could say that It didn't loose any bottom end power to speak of which was what I was expecting. All in all I would say they are a decent investment in the world of $250+ for 20rwhp 6-10rwhp for $100 is worth the money."
For me, during my short test drive, I felt no loss in bottom end acceleration. Keep in mind, this is coupled with the UDP's. The thing for me is that my recent 4.10 addition overshadows mods like this. The hard, neck-snapping pull comes from the gears. The CMCV Delete and UDP just add icing to the cake.
I didn't get the chance to do any hard (T/C off) launches yet, but so far it feels as strong as ever.

On the UPD's, the first thing I noticedafter starting the engine, is that it rev'd up much quicker in neutral. So just based on that, it must have free'd up some belt driven accessory drag.
