4.0l SOHC tuning clippings and notes

[PetroleumJunkie412]

General thread to keep notes on tuning and PCM stuff. Will be updated mostly for record keeping.

Factory base (open loop) maps for the SOHC.

HP Tuners Base tune for a 2011 4.0l SOHC. You will need this if you accidently overwrite your ECM with a botched/modified tune.

Truck is a 2011 4.0l, 4wd, manual transmission. Strategy PYGP1A7

DO NOT BLINDLY OVERWRITE YOUR ECM WITH THIS. CHECK STUFF FIRST. DEMONSTRATION PURPOSES, ETC.

Edit: Ok mod people, how do I upload this?

Interesting email exchange this morning.

Spoke with Przemyslaw Jaworski of V Performance in Poland (http://v-performance.pl/), and he has tuned SOHC rangers in the past. He said the moddbox kit with 3.5 lb of boost on 87 is entirely possible, and he's willing to take on the work for €500. Seems reasonable to me.

It also occurred to me last night that I still have my old SCT tuner with a bunch of 5 star tunes in my parts room. Going to re flash my current tune to theirs, and pull the data back off the truck to see what their maps look like. I remember the tunes themselves being entirely useless, but curiosity has gotten the best of me.

I guess it's good to state why I'm doing this. After seeing how wimpy the factory tune on this truck is, I want to see if I can work through the factory tuning to come up with one suitable for a bone stock engine, then work towards a boosted truck running safely on 87 octane. The nice part of this project is the only thing I'm missing at this point is time. Everything else is currently laying on my work bench - blower, install kit, wideband, tuner, etc.

Never got my truck tuned after installing the SC, got sidetracked with a manual swap.

I’ll be following along.

Clipping: extremely useful old thread on tuning a 2000 explorer with SCT.

How to: - Self Tuning My Supercharged 4.0L SOHC V6

This thread will document my effort to tune my 2000 Explorer Sport powered by the 4.0L SOHC V6 with a modified Banshee M90 supercharger kit installed. The disadvantages of generating my own custom tune: (1) No previous experience in calibrating a PCM; (2) Long learning curve: (3) Risk of...
