Thanks Chris. Damnn, my truck pulled a 9000+Ft pass in Colorado at 60mph (1750 RPM) without even a hint of shifting down or unlock of the TC. Id rather not lose that torque........ :lol:

My truck, with brand new tires on dry pavement from a stop sign will spin the tires for twenty feet!

I love it!

You just described the Jeep I bought ! I want that back ! What kind of mileage do you get?

On the trip out from Nashville the best I got was 38 mpg. From Yellerstone home I was on the verge of 40, until I hit a 20 knot head wind at Spokane all the way to Snoqualmie Pass and that killed that tank down to 37.

Im averaging around 32 around town and normal driving.

What happened to your truck?

I have been really happy with my GDE tune, but I never had Inmotion either to compare it to. I'm running larger A/T tires, and on a 400 mile trip this weekend, my EVIC was reading 34.3 when I got home, and that was carrying myself +2 adults and assorted travel paraphernalia, running A/C the whole way. I haven't hand-calculated it yet, because I haven't had to fill it up!

I know exactly what you're talking about with the linear power delivery. Very easy throttle (I know, I know) tip-in at low speeds. The only difference I've noticed that concerns me is that I can hear the turbo more now when I have the radio off. Not the sucking sound, but. . . a harmonic (?) sound coming from that area.

I noticed the throttle tip-in improvements too. There used to be some harshness with light throttle application/removal that I always attributed to drivetrain lash. With the GDE tune, I no longer notice this.

So is this possible? The GDE tune can give us 35+ mpg? This is an honest number?

If so... *drool* WANT THAT. How much of the F37 does it un-fook? I don't care about arse-crushing torque, but the power has always been enough WITH the F37 for me, so if the torque is comparable but the mileage is that much better... WOW.

GDE is not willing to claim on their website that it will return that kind of mileage, but mine is significantly improved by 30+%. I was running ORM before, too. I was at 23 mpg hand-calculated, 26.5 mpg by EVIC, now I am getting at least 26 mpg hand-calculated (that was figured at only half a tank running GDE) and 34+ by EVIC.

A lot of posts hinting how the jeep shifts different, doesn't let go of the TC to downshift etc...

So, does this tune have the ability to change how the jeep AT shifts ? upto what extent ? can they modify shift points at please?

Nope. That's keeping hyper accurate details on home many miles driven and how many gallons used. I have a record of every fuel stop ever made. How many miles, how many gallons, what additives used and what the fuel costs were.

NOPE! Books on every fuel stop ever. Where, when, how much fuel how much additive. Fuel costs and station location....

Oh, and add a Tom Tom to that hyper accurate mileage information. :lol:

I hate that. You try to be gentle sometimes, and it gets all jumpy just like a loose drivetrain.

What are you using for miles traveled? Some believe the odometer is 10% low. That would make my 28.499 mpg per odometer a corrected 31.339 mpg that puts a big grin on my face :lol:

I've not found that feature on my tom-tom yet.

The GDE tune doesn't reprogram that computer. The TCM's shift points are a map of pedal position vs. vehicle speed that that dictates when the transmission shifts.

If however, you now make enough torque to keep going up that hill with a lighter pedal position, the transmission won't downshift or unlock the torque converter.

I think that is what people are seeing.

chrispitude, thanks a lot, i really appreciate it.

The "tip in" on in motion is kind of annoying when your trying to be nice, i agree there. When i had my lift installed at all j's a tec there said "it sure moves out easy from a stop, it's almost hard to control"

This also applies to low 4 in a big way.

I guess you just get used to it, to be fair though, my wife's Saturn absolutely jumps forward on the feathered throttle, so i guess it's relative to what your used to.

If chris is accurate, and the gde has less peak tq (witch is something they clearly state when they say instead of shuddering it downshifts) It would be nice to not have the rumble, but to be honest with all of you, with the in motion, i never drop out of top gear. I have seriously set the cruise control to 65 (62 on my speedo) and gone from San diego, to vegas, on the 15, and never changed gear. I can also go through the imperial/san diego pass without loosing top gear. IS this better than better mpg?

Probably not.
To be honest here, the imII is not advertised as super economical.
And as far as smoke goes, i can make it all day long, at will, and it's not all coming from the tailpipe.

I am eagerly awaiting more comparisons!

You know, I think you hit the nail on the head, and finally made this click for me.

The GDE tune can drop out of lockup on some grades. However, the only reason I previously wanted to maintain lockup so badly was to keep things efficient. The burning need to "maintain lockup at all costs" goes away with the GDE because you get great fuel economy either way.

When I sold Fred the CRD, I told him that the vehicle almost had two different driving personalities - in lockup, and out of lockup. I found that when I drove the GDE tune, this dual personality is much less pronounced - lockup is no longer the shuddering torque monster it used to be, but out-of-lockup at part-throttle positions feels much more efficient and drives nicer. With the GDE, I found myself just driving the darn thing without caring whether I was doing 50mph or 53mph (and you all know what I'm talking about...).

- Chris

Chris and I discussed it a bit this past weekend as he got a chance to drive the CRD (formerly his) with the GDE tune and give me his take on it. I think we both agreed that it would be nice if the GDE tune could upon WOT (and perhaps other conditions) deliver the same (or similar) amount of crazy torque that IM did while maintaining the niceties of the GDE tune during "normal" driving.

'Crazy torque' breaks things. GDE went to extensive lengths to assure the hardware stays within design limits. That's the only reason this cal was allowed on my machine.
