Engine/Transmission (1998.5 - 2002) Cheap High Idle, Oem Feature?

[Mick2500]

Mschevey Mike,

It's under DATA, PID $1E PTO STATUS

If I click on the status it indicates it was received from address $D1 Manufacturer Specific Data.

Hope that answers your question.

Electrical circuitry has been beyond me for quite some time. I read through the post and will admit that I am lost. However, I did create an adjustable idle control for my truck. Cost for materials was $0 and took me less than 30 minutes. I picked up some scrap wood and cut to 21 inches. Cut a "V" notch on one end. Like SNOKING, I wedged between seat and gas. If your Ram is equipped with power seats, you can move the seat forward and backwards to adjust idle. I have found that using the front of the seat up and down adjustmen allows me to fine tune my idle. Just a thought.

ON TO SOMETHING???

I tested my 2001. 5 yesterday. I attached my OBD-II scan tool (Alex Peper's) and looked at the data. There is a PTO Status line. With no connection to the PTO (orange) wire, the PTO Status line indicated OFF. I applied +12V to the PTO wire through a 150 Ohm resistor and checked the PTO Status line, it was still OFF. Next I grounded the PTO wire through the same 150 Ohm resistor and the PTO Status went to ON. For our trucks it appears that GROUND is what activates the PTO Status.

While I was playing, I tried every combination of cruise control (electronic) settings I could think of. NOTHING would change the idle speed on my truck.



Good luck!



Mick

Has anyone tried to see what happens when the truck is hooked up to INSITE (sp) with the orange PTO wire grounded?



I can imagine the software has been hooked up to a truck but was the wire actually grounded at the time?

After 2 months without a computer... I'm BACK!



For anyone wanting to build the high idle box... here is the source for the connectors for the TPS.



The web site is http://www.deutschipd.com. Their phone number is (909) 765-2250



You will need one each Deutsch receptacle assembly

Part Number: DT066S

Part Number: DT046P



You will also need (6) 0460-202-1614 terminals and (6) 0462-201-1614 terminals to fit the above assemblies.



Hope it helps!

I understood in the past that there was a commercial box that interfaced idle speed with our cruise control buttons. I do not believe it was an ECM function but rather a truly stand alone box



Seems like some handy folks here around circuit ideas.



Someone game for trying to create a box that would use the existing cruise control for a high idle controller? I've been playing with one on a school bus and must admit using cruise buttons to do this is rather intuitive.



Would you inject a frequency into the vehicle speed sensor or just create a stand alone circuit to run the cruise actuator? How would the steering wheel buttons work if you made your own circuit? How would you not interfere with normal cruise functions?



HMMMMMM???

Wish I knew this source before I cut and spliced the wires for my box.

To start with, I do not own a 24v and do not have access to one to play with. After reading over this thread twice, checking out dodgeram.com (something like that), and spending time on cummins.com I was wondering if this might be a possible solution. First off, I am a new CTD owner ('93 d250) who is researching a 24v heart transplant into a Chevy K3500... I could be wrong in my thinking in here since I do not know the ins and outs of the CTD. Please tell me if I am wrong anywhere in here. IF YOU TRY THIS AND IT KILLS ANYTHING ON YOUR VEHICLE OR ANYONE ELSE'S, I AM NOT RESPONSIBLE. OK now that I have said that... I downloaded Cummins PowerSpec. I realize it requires an Inline I adapter and a 6 or 9 pin plug in the cab of the truck. I also know that DC was thoughtful enough to not use the Cummins ECM and therefore they also left out the 6/9 pin connector for the Inline I. After following this link and clicking on engine compatibility you get a message that the Dodge Ram requires Inline II adapter. Even though I do not posses a 24v I still wanted to figure out an answer because

I am wanting to put a 24v into a conversion project and was deciding if I should stick with the 50pin or go all out and switch to 100pin... But back to the subject at hand. I downloaded Cummins Powerspec program and began looking through it. In edit feature's specs menu, I selected create new. Then I selected ISB, followed by pickup and delivery. Select Enable PTO device and what other options I wanted to play with. Next I chose Max Performance. Went down through the list selecting what I wanted and didn't until I got to PTO. Select PTO feature enable, yes. Select customize PTO feature, yes. Warning appears, click OK. Then I discovered what you will soon see if you are following along with me in the program. It has a selection labeled: PTO Set Switch Engine Speed. According to the help section, this is the same button as, you guessed it, your cruise control works off of. This is where I can't help any more and thinking there may be some willing individual out there who will try this out and put a high idle speed (1200rpm) in this blank and see what it does. If you have any questions don't hesitate to call. I am very interested in figuring this out... 432-416-0157

Question for Gizmo 007



On your schematic, instead of using 12v source for the pot. Would it be possible to use the wire DB/WT (APPS Sensor Supply) #5 on your schematic.



I ASSUME this must supply ~ five volts to the APPS???



Also I have a 99 service manual if you had a question about that manual.

 

[Gizmo 007]

C. , yes you can use the +5 volt line feeding your apps sensor. I used a stand alone +12 volt lead because I have more functions than just high idle that my box currently controls. Some of which I will be sharing with you as they are better developed.



ECappleman, sorry for the delay dude. But at least you're not the only one that spliced. I still have mine soldered in also.



kd5hge, due to Chrysler's restrictions on our ECMs, many of the features of the Cummins computer have been left out. Kinda sucks.

 

[kd5hge]

007 I read about the different PCM and other items but from what I can tell on the cummins website, the Inline II will allow you to connect to and modify the software in the PCM. I know that there are differences but I still think this may work. I am open to explainations of why it won't but until it can be proven to me what it won't work even though the Cummins website says that with the proper connector, from your local Cummins supplier, and the Powerspec software you can connect to, read files off of and upload files to the PCM. I will talk to the local Cummins people here in town and see what they think. So far they seem to be very knowledgeable... If anyone can tell me a specific reason why it won't work then I will drop it but I think it will work...

 

[obert]

there was mention of using diodes, but they arent on the scematic above. Where do they go if i need them, adnwhat direction?



Electronics dont scare me but i want to make shure i get this right without frying anything...

 

[datablitz]

just wondering, if any of these ideas are for a 12v or is this all for a 24v? is there a easy way for the 12v?

 

[geusterman]

Easy way for all is stick from seat to floor. Second is a manual throttle cable from dash to something. Makes a cheap cruise that gets good mileage. geusterman

 

[Mschevey]

kd5hge: Because we have a striped down ECM controlling our trucks, the programing features of the Cummins ECM just are not there. Even with the cable you are talking about, you can only modify some parameters in the programing, not add or re-program anything. One of the items Dodge decided we didn't need was a high idle feature, another feature I would of liked that we can't have is the electrically controlled fan clutch.



I was working on a adapter box to convert a Dodge Cunmmins (50 PIN ECM) to a full fledged Cummins (100 PIN ECM). There are a lot of interfacing issues. But I have most of the layout done I Just can't find a source for the connectors used for the ECM. I would need both male and female versions as both flange mounted and cable connected. if anybody know were I can find these please let me know.

Mike:



I would make friends with the folks at Bully Dog or Edge Products - they make boxes for the GM diesels which have VERY complicated connectors... . it would only make sense that they could get their hands on some Chrysler connectors.



Marco is also another good guy to make friends with. He does custom ECM work for the Cummins/Dodge and lots of other engines/cars.....

I tried Deutsch they have a 2500 part minimum. They referred me to a distributor LADD (http://www.laddinc.com ).



LADD has a $50 minimum order and could not refer me to anyone else who could help me with these connectors.

Gizmo's schematic is very basic and does not need any diodes. It works but needs expanded upon. I haven't talked to him since I finished my box but he was very helpful during the planning phase.



The main problem I found with the posted schematic is that when the pot is turned all the way down, the ECM recieves zero volts and will freak out. Symptoms ranged from the high idle circuit having no effect until it was reset to the engine reving up to max rpms. Supplying at least 0. 46 volts to the ECM at all times while the engine is running will cure this.



For more info and the circuit I am currently using go here.

Maybe this is something for a group purchase. How much does each connector cost? I am interested and would be willing to put together an order. I need a high idler for on board air.

LADD will sell them they just want a $50 minimum order. I will be near Dayton sometime in Jan. for work. I hope to stop by there then. I was told one of the connectors was ~ $1. 50 (?) on the phone. The woman I talked with ask me if I needed a crimper or other parts. So I figure get a crimper and what ever else they sell that I can make use of just to get the $50 minimum. Let me know if you get a bunch of connectors and maybe I will buy from you.



I also have an OBA system. It has the Kilby bracket kit and a York compressor. That is the main reason I am interested in a high idle controller.
