Edge trail jammer

Just installed Edge Tail Jammer, Intake, and Throttle body kit on my 2004 Jeep Wrangler, 4.0L. All went well until I cranked it up. It spit and sputtered and wouldnt stay running for more than 1 minute.

Has anyone else had similar results?

I had a mechanic tell me that the module isnt calibrated (over the phone). According to the sales rep they're supposed to come pre-calibrated.

Any input would be appreciated.

I know the actual engineers who helped create the Edge Trail Jammer. I have worked with the company for almost 6 years now. They are a top notch bunch of guys. The units are programmed before they leave Edge. There is a possibility that there has been a software update since then, but they can tell you that when you call their service line. You will just need to have the units serial number handy. Never heard of this problem though. Call the help line and they will help you out.

Did you disconnect and reconnect the battery? Mine idled really high after I first installed the kit. After disconnecting the battery for a few minutes, it fixed the issue.

Yea, disconnect, wait a minute, then reconnect hte negative battery terminal. That will reset your module and you should be set. let us know what you think of the unit.

I've got a K&N intake on mine, and I honestly don't think it makes enough of a difference besides some cool noise

Honestly, $650 is a bit much for me for a throttle body and control module only to gain 25HP, but if you see a difference let us know!

thanks guys...to answer ya'll question, no, I didnt disconnect the battery and it occured to me shortly afterwards...I took the Jeep to a local Mech and he plugged in a "Calibration Tool" (if thats what you call it), reset the Jeep computer, plugged the Trail Jammer back in, and all was well...he said that when I originally plugged it in it must have some how "confused" the jeep comp. which is why it went bizerk. To make a long story short, the Trail Jammer was programmed exactly how it should have been...it appears it may have been my failure to disconnect the battery....but the instructions didnt specifically state to disconnect the battery.

I do have a question though...when I originally connected the unit, I connected the Intake Temp sensor and the MAP sensor, and there were two plugs left over...my first assumption was that if I had a different year jeep then maybe I would have used the left over plugs...but, when I left the mech shop today I popped the hood and noticed that he had plugged the wires that were left over into the factory plugs that were originally unplugged. I know that probably sounds confusing as hell...anyway, the instructions didnt state anything about that either, so now Im wondering if that was a mistake by the mechanic, or is that whats supposed to be done.

Results...definitely noticed a difference in throttle response, mainly in the 2500-3000 rpm range, but also from start. Its gonna take some gettin used to with the whistle caused by the bigger throttle body, but as Ive read on here, thats common.

One last question...I'm about to put either 32 or 33 inch tires on...I was hoping the Trail Jammer kit would help compensate for the bigger tires, but I'm now thinking that maybe different gears will be the answer. Can anyone confirm or deny this? Or does anyone have any suggestions? What about cost? How much does it cost to change the gears? And does it affect the life span of the engine?

Thanks again for the responses.
