 Subject: computer reset ? 4.7l
IP: Logged
Message:
Hello all,
Now that my engine has a few miles on it, I'm starting to push it, and the computer seems to prefer good mileage. I want the truck to relearn, without going thru a few tankfuls, a more aggressive driving pattern.
So the question is, what's the easiest way to reset the computer on an '01 4.7l auto 2wd truck?
Thanks,
Mark

Yeah, I heard someone else mention the same technique. After break-in, I'm gonna do the "cat-back" thing, and hopefully a K&N gen II, if they ever release it, then I'll reset, too. Odometer currently reads "51 miles". How am I ever gonna keep my foot out of it for 1,000 miles? Sigh.. .. .. ..

Broeheem, I would encourage you to NOT keep your foot out of it during the break in... as long as you keep it under 55 or so.
Motors over the past 10 years are built to much better tolerances. The days of repetative, short, low rpm, warm-up/cool-down procedures are long gone. Break-ins happen much quicker now, and the procedures are not nearly as critical as they once used to be. As a matter of fact, I broke-in my 4.7 by driving it 600 miles from MD to IN while towing a 3000lb vehicle, across the mountains (didn't have much choice, I was moving). However, I did turn off the overdrive, and kept the speed down to 55-60. I then did an oil and filter change when I got there, and reset the computer. After that, I didn't worry about it, changed the oil and filter 3000mi later (4000 total miles), and switched to synthetic (Mobil 1). I couldn't be happier with the results.
I've owned new cars/trucks from the "Big 3" in last 10 years, and they all have very similar break-in recommendations: "keep it under 55 or so, and use brief periods of full-throttle acceleration from various speeds." Following this, the manufactures consider a motor broken-in at 500 miles, and I have to agree... its worked well IMO.
Regards,
Chris S.

I'm gonna try the reset this morning; see what happens. Regarding break-in and keeping truck under 55. If I did that out here in Los Angeles, I'd probably get run over by someones Excursion. Oh well. Gotta go with the flow around here.

You don't have to keep it under 55. You're right about here in LA. I'll run you over myself! ;-D Just keep your speeds varied. Don't hold at one speed or RPM for too long of time and you'll be fine. I wouldn't recommend hitting your speed limiter yet either. You'll have plenty of time to do that!

I did say "55 or so..." :-) I'm sure 10-15mph over won't make any real difference. My points really being, that (1) its actually desirable and recommended by the manufactures to mash the GO pedal for brief spurts, and (2)500 miles just about does it.

Finally got around to resetting the computer yesterday, and can't honestly say there is a big difference. Will make a point of driving harder for the next tank, and see if it rev's out any better. btw, foot on the floor shifts are at about 5400. Does this sound right?

You're still okay at 5400 for a 4.7.

Hey guys, I was just wondering if resetting the computer would help the mpg's? If I reset it and drive very conservatively for one tank of gas would they increase?

I have a 1992 Dodge Dakota, and the oil pressure goes up and down. I was told it is probably the gage. I think it is the oil sending unit. Need your input.
