What is this updated fix for the Hot Tune you speak of? What does it fix? What are the symptoms? I purchased the Hot tune early in the year and am very happy with it however if there is a problem with the tune that requires fixing I want to know about it!

Please and thank you

Just email Keith and he'll email you a updated File. I think some people running it were getting poor MPGs and had shifting issues with city driving.

With the original Hot tune the first gear would hold till 3000 to 3500 RPM's under light throttle driving. Was very annoying in the City or when Wife driving. With the updated version it is much smoother although it lacks the light throttle punch which was fun!

I'm super finicky about my tire pressure. I removed my radio antenna. I avoid using the brakes. I try to use a "pulse and glide" style of driving but with the auto it really doesn't work as well as with a manual. I change my fuel filter every other oil change. I add Power Service to every tank. I"m thinking of bigger tires - from 29.5" to 31" diameter would theoretically gain 5% MPG if rolling resistance does not increase.

Hypermiling in a Jeep - yeah right.....
stock tires to 245/70-17 takes away 2-3 mpg on the freeway. The added vehicle height and tire weight kill it. I'm going back to stock sized tires next.

Got my tune in and Jeep is running good, Got 23 MPG on a 325 mile round trip. Was still getting a P0299 code low boost (only getting 16 psi). Then I gutted the DPF and put the no DPF tune in. Jeep has never ran better, super smooth, quitter and no more P0299. I am sure mileage will go up.

Trip today from SC to MI....I tracked 2 segments of the trip...both segments were 301 miles....I was fully loaded with camping gear plus a car top carrier. Probably averaged about 70 mph..no traffic jams, weather etc. used cc and did not go over 2500 rpms.

1st segment: SC to Richmond, KY 301 miles divided by 12.5 gal = 24 mpg

2nd segment: Richmond, KY to Rossford, OH 301 miles divided by 12.7 gal = 23.7 mpg

That's with the DPF delete, correct? That's roughly 2 mpg better than you were doing before, if I'm not mistaken. I guess I'm not really surprised pulling the cork out of the exhaust can have such gains. I'm so tempted to try it. I'm just not sure I'll pass CT emissions.

Are you saving much money per oil change now that you don't have to use the MB spec stuff at 9/10$/quart?

Here is ANOTHER fuel mileage update....installed the ECO tune 3 weeks ago. Just drove from Calgary, Alberta, to Kelowna, BC, 620 kilometers. Speeds ranging from 70 km/h to 130 km/h, through the rocky mountains, passing up hills ...also have 31 inch tires no lift....filled up before I left and as soon as I arrived..

620 kms, used 53 litres = 8.55 litres per 100km or for my american friends 27.5 mpg. Outstanding.

I was shocked at the power I had when passing up the giant hills...I also like the added engine noise the tune creates.

IT's pretty crazy eh? I drove from Kamloops to Hinton a few weeks ago, I was expecting pretty bad mileage, considering having to drive up the Coquihalla and through the mountains. I got 25 mpg, GPS verifed. It's incredible what this thing can do! I've got a DPF pipe on the way, I'm stoked to see how that improves things.

Glad to see someone else is getting results similar to mine.

Hmmm.... you folks that use oversize tires..... have you checked your odometer for accuracy? Clocked it against a measured mile, or compare with a gps?

I use gps miles to figure mine. My odometer is off about 5 miles per every 100 miles.
