Tuner Adjustments
 
Has anybody messed with shift points? If so what?

Has anybody messed with anything else?

Messed with everything except timing. Raised shift points are nice but the tranny likes to up shift quickly while cruising at part throttle with the shift points raised, dont know why. I prefer it to hold gears longer. It raises the shift point to 6400 rpms but in my logs I shift just under 6400 while in auto stick letting it shift itself so I put them back to stock shift points. It seems to shift harder with the stock shift points which i like

I have my fans lowered since adding a thermo. I have messed with shift points but lowered them back to stock due to city driving preference. I raised the idle across the board but lowered them back to stock since the engine will drop to around 500 rpms after idling in gear at a stop light even with them raised....It only does this with the AC compressor not running.....Johan said they were looking at this as it it another fuel saver nanny. I raised fuel 5% across the board trying to take care of a little STK, but it only took a little HP away, but did lower STK to a stock level. Johan said 4.0 STK was normal with the new style knock sensors and I verified this with the stock tune which would peak at 2.5-3.0 I think guys with Exhaust, CAI might benefit from adding a little fuel in the mid and high side....and for sure with a larger throttle body. I have also messed with the throttle booster, but it seems it just adds to a more agressive tip in and only subracts from the last 25% of the throttle position.

Did you notice any less st after adding your thermostat?

^^^^^ I actually just added it yesterday and have not taken a reading yet. I did run to the carwash to rinse off the coolant I spilled and the truck feels good at running 175-185 degrees at 50+ mph. I bet it staves off a full 1 STK, but just a guess. The thermo was 10 minute job tops, two bolts and no sealant needed. I will say when you pop the neck off have the new thermo out of the box ready to swap because when you pull the stocker out the block will drain a little more coolant and you can stop this by sticking the new one in quickly. The thermo should help a lot when the ambient temp hits 100- 105 degrees here next summer

It made a good improvement on my 08 so was curious about the new one. Heat adds to the st so I figured it would shave some off. With my intake temps at 30 degrees above ambient im sure it has to help. Thanks!

Wish I had more input at this time. As easy as it is to install, I would suggest everyone does it even on an untuned Jeep. Just got back from shopping a little and everything is good with no codes being thrown. I set my low speed fan at 189 degrees and my high speed at 195 degrees. Low speed kicked on once while sitting in Xmas traffic but it never much over 190 ish degrees. I also tried the stock tune with it just to make sure it wouldnt throw any codes in case I had to take it in to dealer....all was fine with stock tune as well.

Just loaded up the trinity on the Jeep, checked the rpm limiter and it was defaulted to 6600 RPM on the 91 octane tune, reading here it sounded like everyone elses was set at 6400 so just curious if this was part of the update to the tuner from DS? Also need some input on what gauges most of you guys keep an eye on so I can get my custom pages set up?
