I have a 2001 3.9 dodge with dual fuel system from dualcurve. Problem I have is the injector simulator is starting to fail. Misfire codes and open injector circuit. Can the simulator be repaired?

I have a 2001 dodge dakota with propane conversion dual fuel set up. Well, the dualcurve electronics are failing one at a time first was the water temp, I bypassed that just by fooling the ecu. Now a new one has come up. The processor shorting the map sensor to where(code P0108 high voltage) the eng...

What I was thinking was maybe change the regulator or the vapor hose to a smaller one then have it switch on only when the cruise control is activated. I may just engineer something to fool the PCM manually and keep it working.

I have a 2001 dodge dakota 3.9 with dual curve system. Well the electronics are failing. The question is can I use part of the system to augment when running on gasoline?

fuel injector simulator is it possible when running on gasoline that it fails to connect a injector? I have a misfire code when burning gasoline. Replaced heads and lifters still get the code. 2001 dodge dakota 3.9 150k. Update; noid test light found the problem. Switched with spare wires and now wo...

I have fuel injector simulator on my dodge and it can't find another one that is good. I was thinking could l put a switch on the fuel injection relay? Will it trip a code?

Still have the 300A mixer?

I have an air shroud 300a. By now you have probably found one.

I bought a propane system off of craigslist. Tank,hoses,electronics,converter,snorkel and carb mixer. The mixer seems to be missing the piece that centers the diapham. I tried to put a picture can't upload. The system came off a 2001 dodge V8. I think the previous owner removed the piece for better ...

I seemed to solve the problem. The dualcurve box failed in controlling the fcv. I contacted carb&turbo in MN I purchased digital controller and tapped into the harness it does a great job. I have injector simulator seems to be failing one cylinder at a time. It has a total of ten leads I have a v6 I...

I pulled the 1" Vapor hose to fix other problems and found heavy end build up about an inch from the reg that was closing the hose off to about 1/2" internally for about 3"... This is the last time I strip stuff from other trucks without checking them! :oops: I am having issues my system is going o...

Frank,
Thanks for the info and part number.

Franz,
The big question where do I find one? Easy to replace two wires one screw. What can be used as a replacement? I think it works like IAC solenoid [Idle air control] does the same thing on a bigger scale.

Franz, I did pull off the hose slowly and it did what you wrote stumble/smooth. With the voltmeter on the fuel control valve I would adjust and watch the meter I had it leaned out to the point of killed the engine and the other way rich to the point I could smell it. I found I think a happy medium d...
