QUESTION!! (non urgent!!)

Cadash · #1 Mon, August 17th, 2009, 01:14 PM

Good day to all!! Well it looks like injectors aregonna be done REAL soon. Sooner than I though. I am going with 175/146 Single shots from Swamps. So it looks like Im going from the lightly modded to the highly modded category!! Moving up in life!! So the questions are:

1: How much to move up from the FU to the FU2 package? Is the setup still the same, like having all the tunes available only compensated for my injectors?

2: Since I have PMRs can the tuning be adjusted conservatively?

3: Am I forgetting anything?

I think thats it, I sure something will popup as soon as I close the screen. Thanks!!

I think Swamps is a PHP dealer, not sure, yes you get all your tunes but modded to match the injectors. Bill or Cody will correct me if I am wrong, but the PMR's dont like the SOI to far advanced which will window a block... from my understanding the PMR's are extremely strong against direct force but more brittle than forged rods so they will snap under a twisting or bending force.

I have ZERO experience with breaking anything (not complaining about that).

However, looking at some math and all of the physics that go with it, I really don't think that I personally would want single shot injectors in my PMR truck. Yes, mine has PMRs and I'm not trying to dissuade you from getting them. It just happens to bother me that the one large unbuffered "bang" from a single shot injector may not be conducive to long PMR life.

I may be talking out of my butt though.
I'm sure that Jonathan at Swamps will get you some kick-*** tunes made up for those injectors. I'll get something similar once I get my forged rod short block rebuilt.....

I hate making decisions like this!!! Hes the one I spoke to today and helped me make the decision on the single shots. I was gonna get splits but after talking to him for a while I decided on the splits. I said I had PMRs almost a million times too!!! Im lost!!! Now I definitely dont know what to do...

Well, which is it?

I'm assuming you are going with singles. Singles will work fine on a PMR engine as long as the injection timing is kept to a reasonable limit. It's the overly aggressive timing curves associated with the jump to singles (which will inherently increase the point of combustion) along with the additional timing that would normally be used for standard performance programs. Between the two, well... as Dennis Hopper once said, "Bad things, man. Bad things."

We'd still like to get you down here for some live tuning when you've got time.

If you can swing it, let me know.

Take care.

Lovely!!! You see what happens when I get all worked up!!! I cant even type straight!! But yes, I was looking at splits but after a long talk with Jonathan at Swamps I decided on the singles. Well thats good news then!! As long as my tuner keeps things reasonable that will be my route

I most definitely can make the trip!! Just a matter of when. BUT.....and I do stress the BUT!!!! My whole injector thing started with my #3 injector failing the cylinder contribution test. Truck feels great and runs great. Its just messing with my head now!!!
