So a reflash of the PCM will not reset the ESP to on, which should be the default?

The steps outlined in the owners manual. I have repeated those until I am blue in the face with no luck. Last resort is to reflash the computer and I really don't want to pay the dealer for that.

Then let me rephrase the question. How do I do a recalibration with the Predator when it is not prompting me to do one? The Update instructions for the Predator don't cover this situation. I really don't want to take to another dealer....

Just had a sensor replaced at the dealer. Had been forced to do the ESP disable to make the Jeep drivable until the dealer could fix the sensor. ESP is the only thing that did not get reset. I think the dealer couldn't do it either and gave it back as it was.

Now I'm wondering if the only way to ...

Well, no joy. The indicator light is still on and the display says ESPOFF even though the Predator said I had enabled it successfully. I even installed the 87 perf tune to see if that would help. No joy. No trouble codes either. Anything else I can try with the Predator?

Thank you. I didn't want to unlock it from my 05 Ram until I knew it could be used.

Can I use the Predator to turn on the ESP in my 09 Jeep Wrangler? Had to do the owner's manual hokey pokey to turn it off when a sensor went out. Dealer fixed the sensor but would not turn on the ESP since I had turned it off. Did the hokey pokey again but no joy. Hoping the Predator can help me out.

I have the 9r14.crom and being new to using a DSP, was wondering why I can't adjust the transmission except under the stock tune? Am I missing something obvious?

OUCH! Guess I won't be experimenting with that. Wonder who has a good custom tune for the MPG Booster? Hopefully doesn't cost an arm and a leg, otherwise it defeats the purpose.

Unfortunately, the Ram Hemi is not a flex fuel vehicle but I was thinking maybe the 93 tune might be a bit of a work-around. Can't understand why Dodge did not make it one since GM has the 5.3.

Yeah, wish I had the tools to do my own custom tune.

Has anybody tried E85 with the 93 Performance Tune on a Hemi Ram? Thinking about experimenting and wondered if someone had tried it already. Yes, I know nobody likes ethanol but.......

My 05 Ram is bone stock. I don't plan to spend more money for a custom tune unless somebody has good stats to backup a recommendation. I'm posting my results at dodgeforum.com.

I'm testing the MPG Booster tune on my 05 2500 w/hemi and auto. So far it has not been any better than stock (finishing up my 3rd tank). Going to test the 87 performance tune next (fillup is tomorrow). Hope that shows improvement.

What, if any, are the recommended tweaks to the MPG Booster tune for the U7137?

My truck is an 05 Ram 2500 2wd auto with a Hemi. The canned MPG Booster tune is not getting me anything better than stock (high 14s low 15s) after three tanks of 87 octane.
