Hypertech Max Energy Programmer Reviews

2004 Jeep Liberty

Reviewed By George Y (STAFFORD, VA) Reviewed for a 2004 Jeep Liberty —2/21/2016 1:55 PM

Programmer had to be updated but otherwise easy to install. I've noticed some slight pinging at part throttle and engine knock at full throttle. I am going to contact Hypertech and see what they say about that. Fuel economy is better but may need to run premium fuel. If you are considering this product carefully read there web site about model specific features. For example unless it mentions shift firmness or adjustable shift points you are going to have the stock settings for an A/T.

Hypertech Max Energy Programmer Reviews

limited for a 3.7L

Reviewed By James S (San Antonio, TX) Reviewed for a 2010 Jeep Liberty —4/4/2015 3:23 AM

It's a nice unit but you literally have 4 options. Fuel, rpm, fan temp, tire "speed rating." It did help slightly with my fuel economy, I definitely feel the torque about half throttle. Can't say much more other than I really wish it had a setting to adjust for other than stock tire sizes and not just tire speed ratings. Hypertech has notoriously not responded to the question of why it's not an option for 3.7 liters and auto anything delivered the unit 2 days late.

Hypertech Max Energy Programmer Reviews

Features are (car) model specific - ads are a bit misleading

Reviewed By Michael D (Wendell, NC) Reviewed for a 2006 Jeep Liberty —5/13/2014 7:54 AM

The programmer works well for the functions it covers, but there are several advertised options (shift firmness, shift point settings etc) that are not available for my car/unit. The advertising makes it sound like all options are available on all models
