Sorry I meant to say the Intercooler pipe from mishimoto:

Jeep Wrangler JL 2.0L Performance Intercooler Pipe, 2018+

Everything else is stock.

You donít think is anything with the JB4?

That temp sensor you move from the stock IC pipe to the Mishi one is quite fragile. If when removing it and installing it in the new pipe you put too much pressure on the thermistor you will damage it and the fault you are seeing would be the result.

I suspect the sensor was damaged in moving it over and caused the problem. Replace sensor and see how it goes - it's a $25 part.

You are right, I broke it and install a new one. I took the wrangler to the dealership, the CAI temp sensor was changed. It worked for a few hours and error came back up. Is intermittent now.
I have another appointment this month.

Im new to this forum but have floated around reading as a guest for a while on N54 Tech. I just purchased a 2020 Wrangler Sport 2 door and have a JB4 with data cable on the way. I read through this entire thread and was wondering if there has been any progress on this "hiccup" that is showing itself on map 2 with these jeeps? I come from the VW side of the fence having previously owned a MK7 1.8T with an IS20 swap, FBO and JB4 only, running on unleaded race gas. I'm comfortable enough saying that I have enough experience with JB4's and making custom maps through map 6 that I can pretty much do anything a professional tuner can do, ie: I know what to look for when tuning regarding ignition advance, AFR, fuel trims, etc. My questions (maybe more directed to someone at BMS; and im basing my knowledge off of tuning on VW's) are
1. Are features like FOL adjustment available yet to raise fuel pressure to bring fuel trims down?
2. Boost by gear for the first 3 gears?
3. Setting 1500rpm boost target cell to over 10psi to make the rest of the cells switch to absolute instead of additive?
4. And I'm assuming that all of the logging parameters are available now like IGN advance, AFR, target and actual boost, fuel trims, throttle and rpm?

i also forgot to mention that I am a technician for Chrysler and have access to more information than thr average person would have access to; just so i can lend a hand and help make some progress with making the firmware the best it can be.

The Jeep JB4 options are more limited currently than other models. Boost by gear is actually boost by speed and active, as are the basic logging parameters, but some of the more advanced parameters are not supported yet. There is no absolute mapping, no FOL adjustment yet.

Ok I see. Going to be awesome when everything is up and running. As soon as my JB4 arrives I'm gunna try and do some diagnosing and see what this hiccup might be that some people are experiencing on map 2. Some other members were saying that the hiccup happened although much less aggressively with traction control off which makes me wonder if it can be confirmed that it would go away completely with the ABS fuse pulled as traction control by the button on the dash doesn't fully disable traction control and actually leaves ESC on which may explain the "lesser" hiccup with TCS off. As soon as I get my JB4 hooked up and see what I find I'll make a post.

Sounds like a plan!
