I ran 213 hwy miles and used 14.16 gals of 87 octane fuel. Temps were from 20 to 25 degrees, winds less than 10mph, 95% on cruise at 59mph for approx. 15 mpg. This is up from 14mpg before changing the tune and driving very very conservately. I only passed 2 cars and otherwise never ran the rpms above 2200 and mostly at 1800 rpms on acceleration.
I got the suprechips 3815, 265 tires, edlebrock high flow aircleaner, and I believe a magnaflow exhaust. My trip was a round trip so wind direction and terrain realy should have been discounted.
Tommorow I'll be making another trip with the tuner set for a different option.
It did seem as if the tranny was shifting at lower rpms but that was obviously just because of the way i was driving. I'm also checking the city/town milage today but won't be that many miles. Hopefully next week I'll be cheking with an electric fan setup, just waiting for the controller now.

 

"WIDE OPEN THROTTLE OPERATION
In wide-open throttle (WOT) mode, adaptive memory
in the PCM assures that up-shifts occur at the
preprogrammed optimum speed. WOT operation is
determined from the throttle position sensor, which
is also a part of the emission control system. The initial
setting for the WOT upshift is below the optimum
engine speed. As WOT shifts are repeated, the
PCM learns the time required to complete the shifts
by comparing the engine speed when the shifts occur
to the optimum speed. After each shift, the PCM
adjusts the shift point until the optimum speed is
BR/BE AUTOMATIC TRANSMISSION - 46RE 21 - 541
ELECTRONIC GOVERNOR (Continued)
reached. The PCM also considers vehicle loading,
grade and engine performance changes due to high
altitude in determining when to make WOT shifts. It
does this by measuring vehicle and engine acceleration
and then factoring in the shift time."

by that statement it sure sounds like there can be some control over shift points by the software?
what is the difference between the electronically governed 46re and the hydrollically governed 46rh then? I know the OD is controled by the tcm and lockup is controled by the tcm on the 46re but Everything I read implys the 46re was a fully electronically controlled trans. tv cable could still be used as reference point by trans but the I dont see how it could prevent any alteration of actual shift points?
heres more from the same discussion...
Terry,

So, it seems that the slope of the governor pressure curve can change depending on engine conditions. What that would mean is IF the PCM determines high load conditions (WOT), then it can increase or decrease governor pressure to make the transmission upshift/downshift at a different time.

The examples below are just made up out of thin air. Have no idea whether this applies.

For example, the PCM sees the 2-3 shifts occur at 44 mph at WOT at 4800 engine rpms. The governor pressure commanded could be reduced to cause an earlier upshift. It would be possible for the PCM to record @ what governor psi the transmission shifted and at what engine speed like so:

1-2 shift WOT --- 20 governor psi 4900 rpm 30 mph
2-3 shift WOT --- 34 governor psi 4800 rpm 49 mph

If this did not match a table in the PCM, then it's possible the PCM could reduce governor psi to achieve an earlier upshift.

1-2 shift WOT --- 17 governor psi 4500 rpm 28 mph
2-3 shift WOT --- 31 governor psi 4600 rpm 46 mph

Obviously the PCM has no control over the TV, so I would imagine this system assumes the TV is in good working order and its likely shift points can only be adjusted a small amount.

I've not seen that information, but it is reasonable and likely such a system is in place, but what models/years and how do you diagnose a fault!? I doubt Dodge bothers to document the system further than the statement you just posted.

Thanks for the info.

and yet more from another tuner discussion..

Yes you can adjust the shift point to some extent.
The only things that are electronic on these trany's are converter
lock-up,
overdrive shift, and it does have an electronic gov.
You still can adjust the shift points with the TV cable.
If the trany's were fully electronic ( no TV ) I would agree with you,
but they
still use a manual TV to control the kick down and the shift points. The
only
thing that the computer does to control shift firmness and to some
extent the
shift points is with the electronic GOV. but this is only under part
throttle
and has no effect on WOT.
This is why installing the JET stage II chip firms up the part throttle
shifts
( it increases the gov. pressure a little more ).
this makes sense and is likely where the change in shifting behavior comes from with a tuner...Its still very confusing that the re is considered electronically governed...

 

I'm about to head out of town for the day and have briefly scanned this topic by request so I hope I'm answering what is needed.

With SCT, not Superchips but sctflash, I can change the shift points at WOT and/or part throttle with trucks from '96 to '03 that have the JTEC pcm. That's the 5.2 and 5.9's and the 3.9. An '01 5.9 Ram/Dakota/Durango/etc can have their shift point increased. The 4.7s and hemi's I raise the rev limiter and folks manually shift higher but the 5.2 and 5.9's get it done automatically.

Generally, for stock 5.2/5.9 engines, I set the wot shift point to about 5100. Some of these highly modified 408's can get 6000 rpm shift points
