You know, after thinking about it I think there's something wrong with the wiring to the MAP sensor. The DTC chart just has a generic description for a sensor fault for an OBD I code 14, but OBD II has three, two for high/low voltage and one a sensor fault. I checked voltage at the connector...

Well, I replaced the MAP sensor and set out to put some miles on the car. On the initial test drive in the neighborhood, it fumbled and backfired a bit then cleared up. It started running better so I decided to go further. My wife and I (because breakdowns are more fun with company) drove it...

I read your build and it's great. Again, thanks for posting it. The only question I have for now is where did you get the cruise control buttons?

I must have missed your message. I have bought and sold a bunch of parts over Facebook Marketplace using their payment system which has a goods and services option, and PayPal without any problems. This guy wanted to use Zelle. I figured since it was a service my bank offered, there wouldn't be...

I like your idea of using it. I would do the same if I had the CTM and power door locks. I just want to make sure I won't have any issues because of missing hardware.

I posted the PCM part nunumber and asked about if VTSS could be turned off in the Magnum EFI group. Here are screen shots of that conversation.

Yeah, I just saw that. It looks like something Arduino based, but I didn't ask about it.

Where did you get the cruise control buttons from?

Thanks for posting your build. I'll check it out.

Got it installed and it was just bad as I thought it would be with the harness and the A/C box. Top view. It's buried in there. Bottom view. It's right on top of the evaporator housing. I'll have to get creative with the plastic duct work. With it being jammed in here, the spring for the...

Thanks! I wanted to keep as many of the Dakota's modern (in comparison) features as possible. Cruise control is on the list too, just have to figure out how to drive the VSS and the speedometer. I would like to see how you made the cruise work, if you don't mind.

The new MAP sensor is waiting for me to finish up some other things I wanted to fix while waiting for parts. There were a couple of things that were wired wrong in the dash harness and I needed to make a bracket to hold the Dakota's multi function switch. Since I wanted to keep the internet...

Thanks for the links to the PCM's, I'll check them out. Side note, I was scammed on a Mazda tech forum looking for a one year only PCM for a 1991 B2600i 4x4 that I had. After what seemed like a genuine conversation over the forum, I sent paid him for the computer to only hear excuses. I...

I'll let you know what he says if and when I post in the group. I have never balanced time or money, so it's going to be a while before I get a CTM and the wiring.

I joined that group and it seems decent. I haven't posted anything in it yet, but I've seen that Kerry is pretty active in it. I might contact him to see what his opinion is on adding a CTM to my set up.

Thanks again for the knowledge and research. I know a guy that parts out 1st and 2nd gen Dakotas so he might let me get a matching CTM, harness, and fob. A project for later on, for sure.

That explanation makes sense. Having an actual security system would be nice. I worry that someone is going to want my car more than I do and just take it. Harrisburg, PA has been more interested in murder than car theft, FWIW. Would you be able to find a CTM out of another Dakota/Durango and...

I could try that and see what happens. I would think if the circuit was open, it would acknowledge it as unable to communicate.

Thank you so much for sharing this. I knew the 2nd Gen Dakota's had a much more complicated CAN/BUS network from reading performance/race builds using stand alone computers. To be honest, I don't know if the PCM works or not. It seemed like a good deal when I was buying parts. I would hate to...

I'll look up the part number again and see what else comes up for it. A Google search is what identified the PDC and PCM. It was in a plastic tote that I bought with a manual transmission. Yeah, I'm leary of Facebook groups. There are some knowledgeable guys in the groups. It's pretty easy to...

I was hoping to use the 1999 Dakota harness and PCM I already have. Is there a way to see if my PCM has a security feature?

Also, I read that OBD II uses a transponder key and theft deterrent system. One guy suggested that if you have the ignition switch and key, hook them up and tuck them away in the dash. Another suggested using a tuner to turn off the theft deterrent system. I don't have the ignition switch, key...

Yes, this was the article I read a while ago. Thanks for finding it. From my understanding, the Hughes intake is a licensed copy of the Edlebrock Air Gap so performance should be similar. Yeah, while I'm waiting for the MAP sensor I figured I would fix some wiring problems. The fuel level and...

Yeah, the last one I saw was $850 USD. The Hughes intake with all of the brackets for the fuel rails and adapter to run a stock throttle body is $750 USD new. If I remember correctly, the Hughes is based on an Edlebrock design for carbed applications. My car seems to run great with it, so I...

It was running decent until I got the CEL for it. Now it snaps out of throttle when trying to accelerate and it sounds like it's pinging the valves. I know the MAP is one of the main sensors for calculating fuel load and ignition advance in this system.

Also, I had a CEL for a MAP sensor. Once the new one gets here I'll see how different it runs.

I would like to find an M1 that isn't made of unobtainium. Guys want a fortune for them whenever they come up for sale. I read an intake comparison between a stock kegger, ported kegger, Hughes dual plane, and an M1. The M1 was the highest performer with the best flow numbers. The Hughes was...

Yeah, it's not a radical cam based off the profile and how it runs. It also has a Hughes dual plane intake and long tube headers. I'm sure that combination might more than what OBD I can deal with. I feel like I have the vacuum leaks fixed. The Hughes intake doesn't have a provision for the EGR...

I think that was it.

Maybe we're both imagining it, who knows? I feel like I read about it a couple of years ago on an MS2/3 forum or one the that was Magnum motor specific on Tapatalk. And I'm pretty sure the Magnum forum got shut down because I can't find it. Maybe I'll search the interwebs and my bookmarks for it.
