Turbo tuning 2.5L returnless...3L parts???

[Dom1013]

...wondering since my goal is roughly around 210-215whp/tq on 5lbs of boost....can I just use like 3L injectors w/a 3L MAF or something?? the tuning of the duratec is still clear as mud due to the lack of a "illiterate beginners tuning FAQ" what are ALL my options for tuning...

-SCT is one I know of
-S-AFC and bigger injectors
-3L Injectors/MAF to compensate for the boost on a 2.5L mayble????
-Or put the turbo set up on....take it to get a custom chip burned? With bigger injectors??

Just tryna tune this returnless and know of ALL my options...I really dont want to spend like $600+ on a module then pay for tuning(yea yea I know boost and budget i still wanna save if possible)....thanks alot

The only thing you have wrong is thinking that you'll be okay running larger injectors as long as you upgrade the MAF. If you upgrade the injectors at all, you're going to need to get a tune. A Pro-M MAF can be calibrated to modify the signal sent to the computer to make the injectors work under some circumstances, but it's less than perfect. You are better off with a piggyback chip or ECU tuner.

Sorry, I know VERY little about cougars (but much about modifying cars) are there any other ways to install larger injectors with out a band aid approach like a 'MAF translator'? Are there any tuning options that allow someone (an individual, not a company) to make changes to the car's PCM (like HPTuners for the GM guys)

If you have the knowledge of tuning, then you have a number of options.

One to look at that is promoted here is the xcal2 worth having a good read on the tuning ability the "prp" package provides if you want to tune yourself, of course if you do tht yourself then make sure you have a plx m300 or lc-1 wideband on board to interpret what is happening.

SCT Flash Devices - MORE Power . . . Period!

Nautilus performance has those, and can provide custom tunes for them based on datalogs etc.

Nautilus Performance Group


There is also

The TwEECer -- EEC-IV user programmable module

hope this helps


Just noticed in your first post that you indicated you were aware of the SCT, really as far as I know if you wish to program yourself they are the better options as it makes changes within the pcm, rather than intercepting an input/output of some kind like the Emanage and other piggy back type systems.

Of course I am not aware of the actual workings of these as non of the above work for my vehicle, unless I go through rewiring so for me it is emanage...

I want to tune the PCM, if the xCal2 is what I need, then that's what I'll look into.

And obviously I will use a wideband, anyone tuning with out one is a fool looking for trouble. I am partial to the LC-1s as they are cheap, reliable, and can just be used in place of the stock sensor (3 outputs, 2 programmable analog)

Thanks for the info

I am not so familiar with the widebands, haven't needed to buy yet, but I have been recommended the plx-m300, as you can simply put it into where the narrowband is, as it provides the wideband output and narrowband input.

Just an alternative that I have had highly recommended...
