Hesitation in boost and high rpm

polskifacet · January 18, 2017, 12:17:56 PM

Decided to swap the LPFP, might be able to do it tonight. That way it's 100% sure that component cant be checked off the list. Only part left are the actual lines (unlikely) which would be a visual inspection and potentially that flow test and then it would fall back on software.

Any difference here? I am not sure which one I am getting but I think my car falls under the PS-944 vs PS-1024

I would confirm fitment by calling or typing in your Vin number, it looks like the first option may be applicable based on the build date.
PFS-944. Z.
I'm showing based from my Vin number PFS-944.

Just using fordparts.com for reference. I go to a local dealer and get shop discount. My build date is 02/12 so also 944 for me.

Did I miss something in the log?

Looked like it was keeping up fine.

LMS said to check it, I'm just going to change it to minimize push back.

I went down the same path with Unleashed... LPFP, HPFP, FPDM... about $700 worth of parts.. luckily I am mechanically inclined so I didn't pay for installs...

However... that being said.. my car does not support pids for LPFP information... maybe the saw something...

Good luck! If you have any questions about the LPFP swap feel free to PM me.

IIRC, It was like 4 psi from what was commanded. And that was well after the rail crapped out.

I know it looked good, but I also need to get my side taken care of ASAP before too much time passes and the fire under LMS's butt dies down. At least I hope they notice I am serious about fixing the issue and not just being a support leech.

~~Ill post some cold weather logs when I get home~~, AJP tunes, various revisions.

Edit: No sense in posting them twice, thrice etc.

My logs can be found here:

Basic cold weather logs, may not have WOT but has steady state in cold temps.

Here is a plethora of my logs (Most likely you will want to look at the Rev21 logs that are attached, they were logged in 20 degree ambient or so)

That cold is going to put stress on your fuel pressure for sure.

I want to say my IATs are usually ~30 deg warmer than ambient, so 30 IAT would be 0 ambient, cold for sure. And at those temperatures, heck at any temps under 40 or so, transmission takes a lot longer to warm up and is jerky and jumpy anyway because the fluid is cold.
