In short, I love it. 
I pulled my PCM a few days ago to clean off the silicon and then reinstalled it and when I got my chip today I was able to just remove the black bracket and install the chip without having to remove the PCM.
I cut a small piece out of the top of the bracket so it didn't pinch the switch cable but apart from that the bracket is basically still as it was.  |
G'day mate,
Sounds like your one happy camper
Doing the prep before the chip arrived did mean you wasted no time insertin' that sucker. Real glad to hear your stoked.
Out of interest; what were the final tunes you went with, and for what reason?
As far as the RRFRx goes; there is no real noticable improvement mate.
However being a diesel mech in a former life, I'm real touchy about air in fuel systems. As you may know the fuel returns from only one end of each head (front on left head and back on right hand head) and this has a tendency to so call 'dead head' the fuel on the ends with no return. This in turn can trap minute air pockets in these areas and that is why at times you can get an audable rattle in #8 or #6 injector. The same happens in #1 & #2 but you only can only hear 6 & 8 because they are against the firewall on the passenger side (for our US friends; that's the left).
Anyway when International designed the 444Te they had the fuel return coming from the four ends, but in thier wisdom and as a cost saving decision the Ford engineers designed it out
. These are probably the same jokers who routed the CCV into the turbo intake
So by fitting the RiffRaff FRx you are returning the design to original. Also there is a shim mod you can do to the fuel pressure regulator to slightly increase the fuel delivery pressure. RiffRaff designed this into their FRx, so you get that little benifit with this mod as well. So I reckon for around US$120 why not eliminate the possiblity of early injector failure (cheap insurance basically).
Now if you are considering this, I believe the October issue of Diesel World has done test and trials on this RRDFRx you might want to get a hold of that issue and read up on it. I just got the missus to order a copy.
Anyway mate, put your chipped Effie trough your tunes and report back.
I'm about to order mine.
Ohh..and by the way; now that you are
you control that 'mod bug', because when it bits you get a sickness
Take care,
Reg.
