im whan'ting to put true duels on my truck, but im not sure what to do with my o2 sensor, please help . my truck is a 1993 with a 5.9 and i whant to keep my efi. thanks.

 

The best way to have dual system is to have a X or H pipe that connects both sides, that would be the best spot for the O2 sensor.

 

Well, I kinda agree with crazy, but, I remember when discussing keeping my olds on the computer, the issue was that if the o2 sensor was too far away, the exhaust would be too cold, and it would not read properly. Then you'd need a heated o2 sensor, which could work, but apparently wear out faster... So my $.02 is that you need to take this into consideration if this even matters on chryslers with o2 sensors, and if so, I have no clue what to do.

 

i forgot to mention that my truck will be used for wheeling only, as i was thinking was that id put the o2 sensor just after my right side header ,my sensor is at where the crossover pipe merges or id just not use it .i wan't to keep my efi ,so i can run on steep angels without issuses, from the past , i have tried to run a carb ,but the problems of flooding on steep hills is to much.

 

Just run the duals and put the x pipe right where the sensor is right now then put the sensor in the middle of the x pipe. That way the sensor is right where it was originally in case what marcar said happens.

 

I don't know if thats doable. if so, then i agree, do that.

 

If you must run duals, the O2 should be fine in one side. These aren't high strung performance engines we're dealing with here.

 

Lol Hahns, I love how you just pop in here and there now and drop a paragraph or two then leave.

 

i have to agree idk y i am feeling so much stress about this, i should look at this project as a way for every one to learn wth ill give this a shot. i'll post my results when i get this done.
