Post subject:  I finally did it!
Back in 2005 when the KJ CRD was brand new and was being advertised, the catch phrase was "500 mile range". Well, NEITHER of my CRDs ever hit that mark... until now!

With the odometer correction (4%) for my tires, this tank yielded 520.9 miles on 19.8 gallons of diesel fuel. That is the greatest number of miles I have put on a single tank of fuel in ANY vehicle I've ever owned to date. We had some foul weather lately too. I'm really thinking 550 miles could be possible this Summer. This is a 50/50 mix of city/highway driving. The GDE transmission tune is a HUGE contributor to this ability. This is the single biggest reason I own a CRD!

Wooo!
:BANANA:

Congrats Shawn :D
I'll never see 500 miles on any vehicle I have; and I NEVER let my Jeep go to empty because I don't trust it. LOL
That's so cool though. Wish I had a diesel KJ at times. But I like my gasser :mrgreen:

That is incredible! :SOMBRERO: Now how much did those 500 miles cost you at the pump?

That's great! How do you like the GDE transmission tune in terms of how it feels when you drive?

Does it feel sportier? or does it feel more sluggish?

I am thinking of getting the trans tune, but if it makes the vehicle more sluggish I wouldn't want it.

Thanks

It will slightly decrease your coasting ability, particularly while it remains in lock-up (above about 35mph). But it definitely doesn't make the vehicle feel sluggish :mrgreen:

In fact, it seems to improve acceleration - or, at least, you can get up to speed on an onramp a lot faster without going to nearly as high of an rpm range as in the past.

For the previous poster... this cost me about $70 to fill back up completely. But for 520 miles...it was OK. I'm very happy with that! This was Love's B5 blend fuel...I'm not seeing this mileage with other fuels. I'm going back to the Love's truck stop today for more of this liquid gold!

As far as the TCM tune... I have a love/hate relationship with it.

I LOVE the obvious increase in mileage (1.5 MPG increase from the tranny tune alone). I LOVE being able to take my foot off the pedal and the TC stays locked up. And if I'm coasting down a hill at 40 MPH, it will stay locked in 3rd gear and hold the Jeep back so I don't have to use the brakes.

What I HATE about it is that the transmission is more clunky now. The butter-smooth shifting that this transmission was known for is gone now. Sometimes the 3-4 shift will jerk the vehicle it's so bad. It's just made the tranny very clumsy. When I first installed the TCM, it also made the Jeep sluggish IF you were cruising and hit the throttle...it would stay locked up and you'd never get the engine to spin fast enough to really pick up speed. Once you hit 2,000 RPM and beyond, it's FAST...but until then you'd be waiting for the power to come on. After I unplugged the battery for my timing belt change...now it's the opposite. It'll downshift a LOT now...to the point that I almost thought the TCM tune was gone. After a couple thousand miles, it's still downshifting a lot. This is odd.

Would I buy the TCM tune again? Probably. Not 100% certain, but probably based on fuel savings alone.
