  • This tune increases fuel economy by 3-5mpg on average
  • Performance is increased along with a broader torque curve for improved towing capability
  • Horsepower is increased to 185
  • This tune protects the stock torque converter and limits torque output to 270 ft*lb when the TC is in lock-up mode. In all other situations the torque generated can reach 335 ft*lb
  • Low rpm throttle response is more reactive
  • Other features include linear fuel gauge, less use of viscous heater, exhaust temps are reduced

Incredible performance increase. I saw a mileage improvement very close to 25mpg highway but that is likely due to my lead foot. This tune brings the Liberty CRD to the next level. It also solves the "limp mode" problem. The throttle locking issue still seems evident but not much. One thing though: a Transmission rebuild is absolutely essential. If you do this tune without rebuilding your transmission you will destroy the Torque Converter. This is especially true if you use return the TCM! Jeep detuned these engines as an after market "solution" as they were blowing transmissions back during the build years. And ultimately that is why they were discontinued. However using a billet TC by Florida transmissions or Suncoast Diesel and better clutches the transmission problem is solved. I used the Florida Transmission TC. One thing though, if you ever take this to a Jeep dealer make sure they do not reflash your ECM. Tell them you have a tune and you just want the service done without a reflash. I took mine to a Jeep dealer in CT while I was on vacation and the first thing the mechanic said to me was "god I hate these truck". The European Liberty or Cherokee had no such problems

Purchased the Eco tune a month or so ago and saw a easy 3-4 mpg increase with my daily drive to work which is 27 miles one way. Cant wait to update my TC to upgrade to the full tune. GDE does a great job answering any questions or helping with any problems. BEST TUNE ON THE MARKET!

Eco Tune is like having a 5th Cylinder! Much better torque make my CRD much more enjoyable to drive. Very Pleased.

All I can say is WOW! I've had almost a full week on the Eco-Tune and am very impressed. I was a little unsure about spending the money but had to change out the stock glow plugs from 7v to 5v, thus needing the glow logic changed in the ECU, so I figured why not kill two birds with one stone. Keith was extremely helpful as well as super-quick at responding to my emails. Kudos to him for putting up with my somewhat novice questions and making this a quick and painless process! G.D.E. supplies very clear instructions and I would highly recommend them, not only for the superior product but for their customer service as well! -Thank You G.D.E.

I have had it for about 7 months and love it LOVE IT. G.D.E. It works.

Got this tune about 3 years ago, and should have come back to review before now, but my daughter would not give me my Lib back...until now. Great mpg increase, aggressive driving about 28, crawling to work (who wants to get to work in a hurry?) about 31.
