Has anyone tried any of the Stage 1,2 or 3 performance chip ODB2 modules? If so which one and how did they work?
So I tried the PLP+ with heads-up display and data stream , when I upsized tires I checked mpg and went from 22.5 average to 19.5-20. After installation of plp my average is consistent 23.4 so yeah 300 bucks is worth it to see a real gain of 3-4 mpg.Has anyone tried any of the Stage 1,2 or 3 performance chip ODB2 modules?

Your PCM is locked and the OBD port is locked from receiving upstream commands so no engine performance was gainedSo I tried the PLP+ with heads-up display and data stream , when I upsized tires I checked mpg and went from 22.5 average to 19.5-20.

You want to borrow it for 2 weeks and see the difference for yourself? I mean unless you are suggesting this is a 1 of 1 million magical mystery box ? The Jeep itself calculates that mpg , not me.Your PCM is locked and the OBD port is locked from receiving upstream commands so no engine performance was gained
Does that go for a 2014 2.0 L Jeep Compass latitude as well? I'd like a little bit more acceleration. I do a lot of highway driving.Plug-n-play performance chips are pretty much a relic of the past, it used to be hard for engineers to make engines dynamic enough to switch between being fuel efficient and making their peak power but they have long since overcome this, as evidenced by all these tiny 4 cylinders that make more peak power than a V6 of yesteryear with twice the displacement. There is nothing a plug-in chip can hardly do for a modern engine nowadays other than maybe increase the boost past safe levels on a turbo motor.
What year is your Compass? I have a 2014 Compass Latitude. I have no idea what the Latitude package is but my jeep has a 2.0 liter engine. Is a chip worth it? I do quite of bit of highway driving and there are alot of sudden stops and sudden accelerations.I went

But I also bought my wife a 2014 Cherokee when they first came out over 7 years ago so it's my test mule.
The issue with the transmission is. It has limits and you can change those limits for more performance, but in the PCM there is also limits that control nearly the same thing.
Here's an example.
2014 Cherokee stock PCM and TCM trying to do a brake stand
Now a 2016 Cherokee doing the same thing but torque management tuned in both the PCM and TCM
I'll tell you something right now, madness is a ripoff, they are saying they only change the torque in other gears just not 1st and reverse.......well guess what, in the part they are looking at in the TCM, 1st gear is restricted to 295ft/lbs (way more than you'll ever make) and the other gears are at 406ft/lbs. There is certain torque management in the transmission that you don't mess with and specifically upshift and downshifts. You really have to be careful with what you change because you could end up cooking your transmission.
What madness doesn't know is there are 3 other spots in the TCM that limit torque and in the case of the V6 Cherokee they limit torque well below peak values
As you can see the values are well below the peak torque of 239ft/lbs but simply changing these values didn't do anything I had to change values in the PCM as well.
Which gets me back to my next observation, I dont have a 2.4 TCM program to look at because people are too cheap to buy HP Tuners and send me their files, but lets pretend that the TCM has identical limits on the 2.4 like they are on the V6 cherokee. You won't ever make 199ft/lbs of torque with a 2.4 so that table my be useless and not get you any gains. It may only be in the PCM that there is torque limits. However I need to get a copy of a Compass PCM or TCM and see how it all works out.
On the cherokee platform FCA did a lot of terrible things to reduce the performance of the engine and transmission I can only hope they didn't mess up Compass and Renegade platform as well.
