I'm looking to get a little better performance out of my 2017 JK. How much to tune my rig up.

Jon

Hey Bill,

Not sure if I missed it or not, but doesn't look like any upgrades available yet?

Jon

I cannot help you. To much of a Noob. But I can tell you that with a completely stock tranny, I was having the same issue in the 40-45MPH range under light to moderate throttle.

Be interested in...

would love to see some pics of that puppy.

Jon

What do you mean you pull it for 30 seconds? right when you start tuning? When it begins to error out? Can you explain a bit more?

Jon

Yup. 19 times out of 20 mine will fail at the TCM in high speed mode. Every once and a while it will go through with no issues.

Jon

From an electrical stand point my truck is completely stock minus a trailer brake controller and a radar detector, which I have unplugged and has had no change to the issue. No other modules at all....

I still have the same issues with my truck. I have to read the entire thing on low speed mode. Basically set up the laptop and hit go and then go do something else for a half hour and come back. ...

would love to beta test this also. have a couple of lb7 and lly trucks could test this on.

Jon

I have been playing around some. But I have not since the latest release came out, so not sure what additions were made. Hoping to get some time to play this weekend, we will see.

Jon

well I experienced it this weekend. P0087, low fuel pressure, caused by clogged filter do to -25 degree temps.

I have to look around again, but I know that there are several things that can cause...

That is good to hear. I am going to try mine hopefully today and see where it gets me.

Jon

wanna help out with the what does what part so that I can learn the basics? LOL

Jon

I have some basic stuff right now. I am going to be getting my tranny built here in a couple months, and then it is time to learn and really turn up the power.

I think that you will see more...

LOL, I hear yah. Well guess I will just have to learn by dumb luck I guess. lol

Jon

exactly. I think that I may write a TCM a dozen or so times to get it tweaked the way I like it, and then likely never to touch it again, unless some new cool features come out that we are able to...

I'll put you up for a couple nights if you want to roll out and "learn" on my truck. lol

Jon

If I am correct, Safety is when it is in limp mode. It goes into this mode when there are issues with slipping of clutches and what not in the tranny. Lots of times this will happen when someone is...

It seems to only help with certain trucks. I consitantly even with pulling all those fuses, have issues with it reading the TCM. I am always having to switch to low speed to get through it.

For...

I would like to second this.

Jon

I am learning by trial and error at this point, so not sure I can be of much help at this point. I know that tuning diesels is much different then tuning a car, as you don't worry about AFR, you...

I would like to know a bit more on the LS2 also. Getting ready to tune my first one this weekend. Would have been nice with the RTT, going to take some extra work now. geeezzzz.

lol

Jon

Want to add some stuff for us Diesel owners? ;)

Jon

I have those issues as well when scanning, but I think some of those may be from the BCM. For instance, I have a burban that shows an airbag sensor has tripped. Reset it, but comes back all the...

Yup, same exact problem I have. I have not tried reading another vehicle yet. I was hoping to this last weekend, but was not able to make it out to the local GTG we had.

I would be happy to be...
