I used to think the Revel ACM and Revel Amplifier/DSP units were connected via a USB cable. While the T-port connectors appear like standard USB, it's actually unshielded twisted pair wire that uses the A2B automotive audio bus by Analog Devices. A2B supports a 50MB high bandwidth digital bus with up to 32 channels. Looking at the circuit boards of the ACM and Amplifier/DSP I clearly see the AD241 chips.

I can’t see the catch can hurting anything, as long as it’s not full of oil that could stop vapor flow. My factory PVC hose had oil in it, so I’m pretty sure the catch can will work. I don’t know how much oil actually seeps past the valve stem seals, but hopefully its small and that’s all my intake will get now. The only other defense against carbon buildup seems to be the type of oil used. Companies like Valvoline have tried to formulate their oil to reduce deposits. That link has some good info on the subject.

This device is for ditching the factory amplifier/DSP/crossover/time alignment and allows the factory radio to be used with aftermarket amplifiers/crossovers/etc.

Bbf2530... I can see carbon chunks wouldn’t be good for a turbo compressor fan. Thanks for the info! Fortunately, my build up is minimal and hopefully the catch will reduces any new oil coming from the PCV. I know the valve guides will drip some oil too, but i guess I’ll have to take my chances.

Installation manual found on the manufacturers site has more details. ZEN-A2B / DSP12A-A2B

Nav-TV ZEN-A2B Found this device online while researching how to get a pre-amp signal from the HD ACM. It basically takes the unaltered audio signal (USB) from the factory ACM and provides multiple sets of variable pre-amp outputs. If the factory Revel speakers were to be retained, you'd need to install passive crossovers, because there aren't 12/20 individual outputs from this device. This probably isn't for everyone, but I thought this was interesting.

I just installed a JLT Oil Separator on my 2019 2.0L that has about 12K miles on it. The intake manifold needed to be unbolted to get to the PCV valve, and I got to visually see my valves. You can see they are starting to build carbon deposits and I get the old changed every 5K. I sprayed them with some CRC Intake Valve Cleaner before putting everything back together and will let it sit for a while before starting the car. Eventually I'll run some of the cleaner through the intake as directed.

I doubt it includes traffic info. When I first purchased my MKZ, I was able to transfer my lifetime SiriusXM radio subscription from my Fusion for $80, but lost the Infotainment package that Lincoln was to provide for 6 years. Since that is the cheaper subscription, I purchased the Infotainment for a couple years on my own.

I'm not sure how they disassemble, but a Facebook MKZ group was discussing the rocker panels rattling and using new Ford molding clips 6G1Z5410182A. Search eBay for that part number and you'll see what the clip looks like. Maybe that will help.

I had one come loose on a 2010 Escape. I used a stainless steel hose clamp around it and the exhaust and all is good 4 years later.

So are you changing your system to the Sony setup, in order to obtain HDRadio? If so, I think you'll really like, especially if you have decent HDRadio stations in your area. I do and love the cd quality sound. When a station is non-HD I can tell instantly.

I looked all over for APIM values and couldn't find anything related to volume, but I'm certain the Sync upgrade affected my overall volume. Perhaps the Sync upgrade also modifies any ACM settings too? Not sure at this point.

I don't know the details of any artificial engine noise, but the cancelling appears to be doing it's job if the engine seems louder with ANC disabled. The problem is aftermarket audio systems are over amplifying the correction signal, that is ultimately created using feedback from the microphones. I'm beginning to wonder if adding audio taper potentiometers inline with microphone wires would attenuate the feedback signal. This way you could adjust the feedback signal and perhaps the ANC wouldn't generate as large as a correction signal. Perhaps you could find a happy median between too much ANC correction and no correction.

For those not wanting to use Forscan, the 3 microphones connect to the ACM in the trunk. Cut or disconnect 1 wire from each mic and there will be no signal coming in.

I think the APIM controls the volume scale, because my volume was reduced with Sync 3.4 vs 3.3. You’ll need to research Forscan spreadsheets from other Ford forums to see if its been decoded.

Double check the wiring diagram. It looks like the Fusion with Sony Amp/DSP only has 6 channels and the ACM still has 4 onboard channels. See page 132-8 for connector C240A. Junkyard is probably a good place to source the connectors.

High jacked!!!! Sorry guys, need to keep this thread on track about audio.

They are probably molex connectors.

Silver tweeters and speaker grilles indicate it's a Revel Ultima 20 speaker system, black is the 14 speaker.

I've thought about higher end replacements, but not sure how different impedances and efficiencies would affect the Revel amplifier and equalization. Revel put in a great deal of engineering time to match the components. I'm sure they would have loved to have taken the system a step further, but had to work within the constraints set by Lincoln. As far as the Revel speakers, the tweeters and midranges are good for what they do. The Revel lower door and rear deck woofers might benefit from a higher quality driver with more excursion and a rubber surround, such as the Focal set I pointed out above, but I probably won't try it unless I blow one of my OEM drivers. What the Revel systems really need is a true subwoofer and that's something I'm working on for next spring, hence my other thread.

Yeah, iDatalink definitely doesn't support Lincoln Revel, but as you mentioned... it might work for the Fusion application. The Sony amp might be an option too, I'd have to research. Their Maestro DSR1 adds Rockford Fosgate digital signal processing to most aftermarket amplifiers. It uses a vehicle-specific T-harness to intercept the audio from a Fusion ACM, process it and sends it to aftermarket amplifier, then connects the the aftermarket amps speaker leads back to the vehicles speaker wires.

I would not recommend upgrading the 11 speaker system to Revel... unless perhaps you just use your Revel-ACM and investigate the iData Maestro options for aftermarket amps and speakers. As you've probably seen, I have the thread of upgrading Revel from 14 to 20 speakers. That was only possible because most of the wiring, connectors and speaker placement were already in place. To do the upgrade to Revel correctly, you'd need new door panels with the proper speakers and alignments. Then you'd need to run separate speaker connections for all 8 drivers up front and 4 in the rear. You'd also need the proper molex connectors, a Revel 14 channel amp and USB T cable to connect to the ACM. There is little to do in Forscan in the ACM section, but that would be the easy part. All of this work would cost too much (unless you had a donor vehicle) and you could build an aftermarket system that probably sound better. My recommendation would be to upgrade your existing mids and tweeters speakers with something like these Focal Inside IS FORD 165 and run off the factory head unit for the time being. Since your system already has a separate subwoofer amplifier, it would be easy to replace with a better amp and subs. You'll also want to invest in the wiring diagram service manual if you plan to go beyond just a sub amp upgrade, in order to know all the pinouts of the ACM wiring harness.

I had an interesting thought today! I recently learned the non-Revel ACM has built-in amplification for mids/tweeters and a separate amplifier for the subs. So now I'm thinking if a Revel-ACM is configured to add Aux1 for an External Sub then perhaps we could use ACM pins 4 (+) and 17 (-) and 16 (shield) to send a separate low level signal to an aftermarket subwoofer. There are also some ANC mixing settings in the ACM that seem really interesting... might be able to keep ANC enabled this way.

The Audio Control Module (ACM) handles Active Noise Cancelation (ANC) settings. Forscan can be used to modify the settings.
