Just a little update..

I've got the wideband commander installed to moniter A/F ratio


and to adjust the A/F ratio i am using the apexi safc II (super air fuel controller 2)


here's the dodge 2500 diesel intercooler mounted in my truck. Had to notch frame rails & re-route a/c lines for it to fit.

 

You can do a semi-return route like I did. I ran the factory fuel line into my aux pump, then out of that to the RRFPR, the return line from the fpr simply returns to just before the inline pump. Works great.

Let us know how the progress is going.

 

ur ****s gonna be mean dude cant wait to see some time slips

 

In order to run a return line on the dodge vehicles You have to block the stock FPR from regulating. If its like the neons you just need to fill in the area behind the stock FPR O-ring with epoxy. You will have to drill a bulkhead fitting into the Fuel pump canister for the return line. Tap the fuel rail and take out the shraeder valve. Hook up the new FPR and run the return back to the tank. If you need more than a 1:1 this is where the FMU will come in.

If you were to flash the stock PCM I would think you would need at least a 2 bar map sensor in order to see boost. Unless they somehow scaled the numbers so that boost is within the stock 4.7 map sensor.
