I ordered a tuner from Rugue for my 2004 4.0. I was pleased with the whole process. All questions by e-mail were answered by the next day.

He has a pretty good program. $379 for the tuner (xcal II) and $25 extra to get a data logged tune. The data logging involves capturing data and sending the info to Rogue. He will then make a tune specific to your vehicle based on that data. The only way to get better results is to spend a couple hundred more dollars to get a tune done on a dyno. I'm pretty sure a laptop is needed for this. I haven't done mine yet so I can't give a whole lot of specifics yet.

Just an idea of how communicating your needs will help. I asked him about raising the rev limiter when drag racing. I wanted to launch at 1500 rom. My thought was to have the idle bumped to 1500 rpm.
He came back with a brilliant plan IMO. He raised the neutral rev limiter to my launch point at the track. That means I can keep the pedal floored and it will bounce off the rev limiter at 1500 rpm which is where I want to launch. He has it set to disable as soon as I start rolling.

Send him an e-mail if you have any needs. He should get back with you in a day.

 

So you basically have a two stage rev limiter. Sounds like you got hooked up. Congrats

 

exactly. I'm glad someone understood that. Let Fred know what you want and if there is a tuning solution he will come up with it.

 

My roomate had one for his boosted Honda. They are pretty neat.

 

sweet, i need to check them out.

 

RoguePerformance was and probably still is the 3.0 performance authority for many years. I've used variations of several of his mods including the throttle body half-shafting and so forth to coax a little extra out of the little 3.0.

I'm not surprised that he can tune 4.0's as well -- he's been in the motor game for quite a while.

 

Hey! That's ME!

Glad you're please with the tuner and hopefully, we can get you to where "dead" is at, .8% error on the MAF file (Ford is +/- 4%). I jokingly told him I wouldn't touch it again because it can only get worse..

The Data-Logging is quickly becoming my favorite feature of the XCal2's. I've been tweeking the Wife's SOHC Explorer for our NorCal trip next weekend and I had a 6% left/right bank error that suggested the passenger upstream O2 was bad. Got under it today (while doing Pro-Comp ES9000 shocks) and pulled both O2's. The EASY one (driver side) was a Bosch OEM replacement, the Passenger side took over 1.5hrs to remove (through the fender well! remember that trick!) and guess what? OEM Ford, 8 years old with 83,000 miles on it, the body was scraped/dinged and the corners rounded. Someone tried to remove it and failed. Coming from the fenderwell I got a good grip and it pulled right out.

New O2's and the error is undetectable. Gotta' love the data-logging. So far I've found unbalanced injectors, an exhaust leak and bad O2's on two vehicles.

 

Dead wasn't able to make it to the track. The shipping address got messed up for his intake so the quickest he could get it was at 8PM.
I managed .54, .59 reaction times and should have won the dang thing. I got a free run from someone redlighting and I adjusted my dial in time to the fresh run. The next race I broke out. my .54 to the others .72. i had him whooped pretty good. I whoaed it down at the finish line, but not enough.

 

sweet. i need to ditch the flipchip and get an xcal2

 

I have been considering a chip for a while but I kinda think with the funny noises my motor makes and such it might just kill it. Although the data logging might help me figure out why it is making such noises.

 

luke, do you have a thread on the funny noises? I've been in the process of elimination on some noises with my 4.0. Maybe we can swap notes.

 

No I don't. D seems to think it is noisey lifters but I dunno. Itz really loud. My OHV has 77k on it. I kinda think the noise started around 55k when I made the switch to a synthetic blend.

 

ok. Mine is more in the front. Looking like the tensioner assembly.

 

Funny thing is my brother in law has a 2500 hemi ram that makes the same noise. And his dad has a 2500 silverado that has a much quieter but similar noise that chevy told him was the fuel injection system

 

I purchased my x-cal from Rogue Performance as well and you will need a laptop for the data logging part,it's cool to use with just a little bit of a leaning curve the first time you use the program
Now i just need to get a few more data loggs in to him so we can pin this up
But in all great product and service
