Oh yeah. Jeep did great 150 mile round trip. Except when we did a little slow wheelin to get to the top and idled for a few minutes to take some pics and hang out and things got warm.
Engine did great but the FCC cooked up the fuel pump some exposing a major flaw for off roading and it got hot and shut off and wouldn't restart. Combined with the extra heat from the hills we climbed, elevation, and idling. Not enough fuel seems to circulate from the gas tank to keep the sump cool enough as it doesn't draw enough cool gas when it idles the sump can was hotter than hell to the touch. A couple handfuls of ice and a few minutes wait it started back up and cooled off just fine all the way back np once the air circulation and gas circulation did its thing.
It had happened to me right after I installed the new ignition system and was idling in the driveway a few weeks earlier.it died after idling for a long time. I chalked it off to new ignition settings and bigger spark plug gap etc... and the long 20+ minute idle. I tried to duplicate it the next few days but couldn't.
I called fitech support and they said to send it back so that they could test it. And that they would replace the fuel pump if it was defective. Pump worked great and as it should sooo...
Im building an in tank hi pressure fuel pump system tomorrow and FCC will go back to summit with no good recommendations from me for the fitech fuel command center in a 4x4 or any other vehicle that may idle wich pretty much narrows it down to everything....
Summit was great on taking it back though with no hassles. So if you have one, return it before the warranty expires.
