Anybody know what code processor that my truck would have?

2002 F150 stepside auto 5.4 short-wheelbase

 

Hi docdave22,

You have the Ford EEC-V PCM (Powertrain Control Module), but nobody here can tell you what actual catch word (computer code) your particular vehicle has, you'll need to check that for yourself, which is easy to do.

Open your front passenger door, then look in the front part of the door frame, in the area of the door hinges, and there you should find a sticker that has 3 letters followed by 1 number printed on it, like UEV2, KFG1, etc., and that is your computer code. There are many difference codes each model year in these F-150's.

If you have any problems finding your code, give us a shout & we'll be happy to help.

 

Thanks Mike, it is UEV2. I was curious if it was supported by tweecer or eectuner.

Its not.

 

Hi docdave22,

You're right, it's not supported. A lot of the EEC-V stuff in these F-150's isn't supported, as there are just so many different software revisions scattered across so many different templates that the F-150 is among the hardest vehicles for those kinds of devices to keep up with.

Good luck, & do let us know if we can be of assistance.

 

Can you make a flip chip that I could use to flip between a nitrous tune and a N/A tune?

If so, how good of a tune can you get without a dyno?

Also, you would probably know this also, Can I cut the cats off of my truck and use a chip to fix any problems? ie.. codes or driveabilty issues?

 

Hi Docdave22,

Sure, we can easily make a Flip Chip for that type of combination so you can have a proper nitrous program available at the flip of it's switch. You don't have to go to a dyno (though we always like to have that data), but if you want to take it to a chassis dyno for proper A/F ratio testing (no tailpipe sniffing!) after you get the programs, we'll also dial the A/F's in spot-on for you at no additional charge (a few bucks shipping) if any adjustments need to be made or are desired, just give us a call for all the details.

Removing the catalytic converters is of course highly illegal, and when you actually run the dyno numbers on these trucks you'll also find it just doesn't get you a significant power gain. Not since the late 80's to early 90's have cats in general been really restrictive in most American-made vehicles.

To answer your questions, no, you generally do not pick up driveability issues by removing the cats, and yes, we *can* turn off the resulting MIL from the downstream O2's reporting no cats present as we do that for a number of race-only vehicles, but we will not knowingly assist anyone in doing that on any vehicle we know to be street driven. Running with no cats is illegal, and beyond that it's just nmot smart to pollute the air for everyone else (we like breathing clean air, too) just for a potential gain of 5-8 more horsepower @ 5400 rpm. That's all the power you'll gain on a 300 hp or less late-model F-150 from stripping the factory cats completely off, so it's just not worth it.

For those who really want to optimize exhaust flow thru the cats, we can supply at a low cost replacement high performance/high-flow catalytic converters that will prevent the MIL from illuminating and keep you emissions legal, as well as properly open up the flow in the cats to get you that 5-8 horsepower back, and that is what I would suggest doing instead of removing the cats altogether. Many people look at the 4 cats (2 on each side of the motor, a primary & a secondary unit) under these 1997 & up F-150's, Expeditions, etc. and think WOW, 4 cats, that's twice as many, so it must be twice as restrictive! A perfectly natural assumption, but in reality the factory cats actually aren't that restrictive. One of the reasons Ford did that multi-cat design was to keep flow rate up, along with using the first cat's output to heat up the second cat up quicker to aid them with the EPA drive cycle the automakers must go thru to certify for emissions.

To give you an idea, the 4 cats on these late-model F-150's are used on the supercharged Lightnings as well, and we have a number of our customers running low 12 & high 11-second 1/4 mile times THRU those 4 factory cats! Of course, at that power level (500 rear wheel HP), they could pick up 18-20 HP & sometimes even more from going to high flow cats, but some just don't want to make that change, and it's a good example of just how much air those 4 factory cats really can flow under extreme boost levels in the supercharged 5.4's.

Sorry, I don't mean to sound like an enviro-weenie, nor am I trrying to sell our high-flow cats, we just like to help our customers (and us) stay legal & not pollute everyone else's air. These days it's just too easy to accomplish high flow rates and still use catalytic converters. This has changed so very much from the first 12-15 years of catalytic converters (1975 to about 1990 or so roughly), during which time they *were* a significant source of restriction, but not any more, that has improved significantly.

I hope that info helps, & give us a shout for details if you like.

Good luck!
