There is no V10. The V10 is 6.8 liters. 04-10 F140 had a v6, 4.6 V8, or 5.4 V8. Only the F250, Excursion or E250 had the 6.8 V10 option. Also, the tune will work, but new rear o2 sensors are super...

The second set can be turned off on tune… otherwise the nonfoulers also work. But only for the rears. Never use nonfoulers in the front sensors.

One more thing to look at is the Fuel Pump Driver Module. I had intermittent fuel problems on mine until it finally failed. It?s located at the rear frame above the spare tire. Gets corroded easily.

I may be wrong, but I don?t think you can use a cable TB without the IAC. Otherwise you need drive by wire throttle body and pedal so that the ECU can adjust idle air so the engine won?t die. That?s...

That sounds great! I was looking at doing a 6r80 swap into my 04 F150. I used a Saleen supercharger @10psi on my 5.4 3v and my 4r70 is starting to crap out. Select shift would be awesome. Are you...

Thanks! I appreciate the help. However, the sender for the s331 is the same TMAP as the Cobras so the scale is reversed. It uses a second MAP sensor inside the gauge pod as a reference voltage so...

Thanks. That actually answers a lot of questions, because it?s a progressive increase just as my rate to lambda is. It was so odd to see it adding fuel when I was rich according to wideband. This...

My 08 GT500 does the same. And I have to turn key back to off, then back to on in order for it to start. Otherwise, it?ll crank but never start. Only does that post write. What?s the OSID for the EVO...

I?m not at the computer, but at the top of my head, maybe computer or cluster are not original? Maybe PATs is disabled on Evo tune, but reenabled when you copy stock and it doesn?t start? Check PATs...

Update: I got a much better MAF that was within 5% of the generic spectra intake I?m using. I got a wideband installed and sure enough, I?m at AFR 9.9-10.5 through the pull even as my ST/LT read...

Sorry! Hadn?t seen this.
Dashpot affects throttle position, think of it as the idle air control valve on older cars. The settings affect how much air at a minimum it must flow or how slow/fast the...

Yes. That?s my issue. I can see the soot in the exhaust. I can smell the extra fuel. It seems super rich, yet any WOT value registers +25% no matter what I do to the MAF curve. Even if I richen it,...

Sound advice. I haven?t had a chance to install a WB, but I will. I?m glad mine is not the only one going crazy on WOT STFT.

Thanks, I?ll look into that!

I?ve successfully supercharged my 04 F150 5.4 with a takeoff Saleen Supercharger I found on EBay. Idle and part throttle are great. Tons of torque. Once my MAF reads over 3 bolts though, my STFTs...

On the datalog, just noticed your timing is 24! The inferred octane is 95. The octanium raises the inferred octane, and there may be some added timing because of that. Maybe edit the octane modifier...

I checked a stock 2011 tune and you are right, the stock timing is 21. I guess they got more aggressive because the car actually has knock sensors. Mine is an 08. No knock sensors or factory...

I would. You can always work your way back up vs rebuild the motor. If you have knock it?s for a reason. I?m not sure Ford ever went into the 20s sparkwise. The only ones I know is Kenne Belle but...

But you only have to do this for upper load, like at 1.6 and above. Leave higher spark alone at low loads. But nothing at higher loads should be above what I posted.

Correct. Make sure other modifiers aren?t adding either. With 93 octane, 18 degrees is regarded as ?safe?. May wanna go to 16-17 with 91.

Interesting. Well okay then, I figured same engine, same body type, maybe it?ll be same ECU. Ford works in mysterious ways 🤷🏻*♂️ Thanks for your help!

I have an 04 F150 5.4 FX4. I recently acquired an 08 Saleen S331 Supercharger, which is now installed. Final order of business is the tune. What I did was find an S331 tune in the repository and copy...

Best bet is to look at a 07-09 GT500 tune in the repository. Similar ECU, same trans.

The JLT 123 should be okay. With a TVS supercharger (5.8) and a 2.6? pulley you should be looking at around 16-18lbs. I have a 2.5 pulley on mine with 5.8 (52lb) injectors and I?m pretty much maxed...
