2007F150 5.40394-RXDE4DX.PCU

Post by PnyPwr » Wed Jan 04, 2017 11:30 am

I have already bugged Chris via email on this but starting a thread here as well for ongoing info

Using the Deltapal and MAC10 interface

When loading the tune into Dealtapal and using theTMPL file RXDE4_CSS.TMPL and reading through the tune, nothing seems to make sense. The options all seem quite random and I am not willing to change figures I cannot understand. I am a car guy with *some* computer skills.

in SCALARS
engine size is 0 L(??????)
rear axle ratio is 1.5 (true axle ratio is 3.55)

has trans options for 4-5 shift( my truck is a 4r75 with only 4 forward gears)

in REV/SPEED/TRACTION CONTROLS
the vehicle speed limiter is set at 1 mph

in QUICK PERFORMANCE TUNING AREAS
under rear HEGO config instead of a 1 or 0 in being able to turn them on or off I have the numbers 156

This file is vastly different from my 97 Cobra and the stand alones I normally tune.
Thank you for the guidance

Any advice on a recurring p0605 code with a very basic just removed the rear 02 and turned up speed limiter tune?

Starting off slow

well I literally just turned that code off in the tune. not really happy about that solution but it is working...

next question

If I change anything at all past where I am right now - the computer throws multiple ETC codes and runs on 6 cylinders.

Is there a hidden readme file with better instructions that I cant find? I have gone through the f1 help section and read every help item in an attempt to figure out what has to be changed "together" to keep the ECU happy.
I have a supercharger waiting to be installed this spring but I need to have a working knowledge of this system before the mechanical can be done.

I will be installing a roush M112
39lb injectors(03 cobra)
gt500 TB and oem air intake with slot maf

guidance appreciated

Not sure why you're having ETC errors and only running on 6 cylinders. Maybe making unnecessary changes in the tune? If you want to email me the tune I can take a look.
