Hey, I am about to order the portfueler from Hahn and just had a few questions. How does the Aeromotive 1:1 regulator go in? Do you take out your stock FPR? Also, what's the order of the fuel lines, does it go from the pump to the stock fuel rail, to the portfueler rail, then to the 1:1 and then return to the tank? Last, how easy is the software that comes with it to tune if you have a wideband O2? Thanks for any help.

That is 100% correct on the fuel line setup. As for the software, I've never used it so I couldn't tell ya. Just to re-iterate, the fuel lines go like this: line up to OEM rail, line to PF rail, line to 1:1, line to return line.

the fuel software is pretty easy it helps to have a datalogger that will read boost, rpm and air fuel like the zeitronix because the fuel table is like a spreadsheet.
across the top is the boost level in .5 psi incriments down the left is rpm in 500 rpm incriments
the boost sensor and tach sensor inside the PF module find the appropriate cell and turn on the injectors for the length of time based on the cells contents
you can adjust each cell + or - based on what your datalogger says for that given rpm and boost setting or there is a select all function and you can adjust the entire map percentage wise.
My PF with the 440cc injectors came with a map that was 9:1 at 10psi so tuning is a definite must

I am also going with the 440cc injectors from RC. I am getting the boost sensor for the Zeitronix as well, how long did it take you to tune your car once you got the portfueler installed? Thanks for the info bro!

How long have you had the portfueler for??? Do you have to constantly keep retuning it? I live in a place where the temperature between night and day are pretty dramatic. Will I have problems with that? Thanks for all the info so far though.

Give it a try, the worst thing that can happen is that you will tune it well for the cold and it will be rich when it heats up.
or
Stick your big injectors in the primary rail (controlled by the stock ECU) and hook the stock ones up to the PF. You will have less error that way, in theory at least.

The big injectors are too large to be controlled by the ecu. The standard is 440cc. It would run hella rich when not in boost. Now I have read that its a good idea to put the stock injectors in the portfueler rail and the secondaries in the primary rail and switch the harnesses.

Why would this be better, just because of the position of the injectors for atomization maybe?? Just a guess.

The stock ECU is able to correct for air temperature, the PF, 034EIC, etc... doesn't.
Putting the injectors controlled by the ECU further from the cylinders could make the problem worse. It may have unpredictable results - the equilibrium between evaporation and condensation of fuel pooling on the intake tract will certainly be different than the ECU expects, it may be able to correct for this to some extent, or there may not be any noticeable difference at all. Experiment... see what works best for your setup.
