Perfect.

Thank you. I was worried with the heat the tape wouldn't hold but I will give it shot. Hopefully this will get rid of the connectivity issues.

I can confirm I have not had this issue just 2 days ago with the stock exhaust, but with Mishi CAI, IC pipe, and DV+ installed. It's been running fine for many months in that configuration.

It's on Map2 but also to a lesser degree on Map1.

Interesting, and any issues using map6 set to 2psi across the board?

[drburns]

Terry, do you think the exhaust could be a contributing factor? However, there are totally stock keeps experiencing the same issues.

Map6 with 2psi across the range drives fine.

Map1 and Map2 both drive fine if I "roll into" the throttle from 15 mph. If I go WOT from a standing stop I get the lurch.

On Map6 no lurch with WOT from standing start.

Wonder if it's eTorque related? Feels like it might be somehow related. In my roll-on tests eTorque would already be out fo the picture.

I don't think it's exhaust related but too early to tell for sure.

I noticed today that the iat stayed at 0 for a while on cold start this morning, then jumped to 78* and stayed there the whole drive. It eventually got to 84*, but that doesn’t seem right, and it doesn’t seem to be reading accurately and changing accordingly. It seemed fine a couple of days ago. Not sure why it’s so glitchy.

EDIT: after getting back in the Jeep after a short drive the iat seemed to work fine. So weird.

[drburns]

I can confirm that for a 20 min drive in 70* air the iat stayed at 77* and slowly crept to 82* and maxed at 86*. It never read below 77*. I don’t think the intercooler could be that efficient, could it?

[Terry @ BMS]

It could be the IAT parameter is returning MAF intake temps rather than charge air temps. If so we'll have to keep hunting to get what we want.

Not sure where the MAF is in the Jeep?

[Terry @ BMS]

Would be on the intake somewhere, I'd have to poke around myself under the hood and don't have one here full time which has been slowing down the development. One of our guys will buy one sooner or later.

[drburns]

I don’t think the Jeep uses an maf sensor. It uses the IAT and MAP sensors to calculate air flow and fueling.

If you have a video or photos of the intake path I can check to confirm there isn't a MAF sensor. I can't remember off hand.

Here's the install videos from Mishimoto for the intake and the intercooler charge pipe. These videos should give you a good look at the intake path.

No MAF sensor but instead has a dedicated intake temp sensor. So that might be what the JB4 is monitoring currently. Once we're able to get one in house or borrow one for a few days we'll sort out how to monitor charge air temperatures.

Hazynighthawk when you get an update let me know. I have a 2020 cherokee 2.0t and I'm debating on getting this if it actually works for you.

So I solved my problems so far.

I couldn't wait for screws and everywhere I went to try to buy them didn't work so I used ZIP TIES to hold the connection together. I hope they last and when I get the screws from Burger, I will swap them when I need to but so far its been holding.

After moving the bluetooth connecter to where DrBurns had his I solved my connectivity issues.

So far so good and finally happy after a torturous back and forth I am sure for all.

Thanks everyone for the help and this is what the forums are about. I appreciate everyone's input and contributions.

Just let me know if I should be concerned about zip ties LOL.

I hope everyone solves their issues because this is a great mod once its all together.

I hope they keep updates frequent...does anyone know the best way to stay up to date?

Thanks again all.

Vinnie

Glad you got it sorted out! Probably just check the app for updates every once in a while. I’m sure there will be more to come based on the conversations on this thread.

Hi Terry,

Also remember the Jeep has a separate coolant loop for the liquid to air intercooler and a couple sensors in that system. I think another coolant temp sensor and another air temp as two plugs coming out of it - right below where the boost and map sensors are that the JB4 piggybacks.

You may want to get those sorted when you get a donor Jeep to play with.

Mostly because of you. Grateful!

[drburns]

The sensor in the charge pipe just below the map sensor is listed as an EGT sensor, so I'm not sure if that makes a difference. I had to order a new one when I installed the charge pipe because I cracked the connector off the sensor trying to remove the plug. They really use the cheapest most brittle plastic in these sensors.

Hopefully the guys got those sent out to you so you can add them in shortly! If no codes it's fine for now but longer term best to have it properly secured.

Thanks Terry. Fingers crossed when the get here but everything I tried wouldn’t work. I took apart computer screws and they would only thread in so far and stop. I think that’s why they never did it at the factory.

No matter how short the screw it just wouldn’t thread in anymore.

I bet something is wrong with the sleeves which is why they didn’t do it originally.

I will let you know when I get your screws and try. I think I have something defective in the joint connection.

Fingers crossed.

I installed the jb4 last week along with the mishimoto cold air intake and charge pipe and it has run smoothly until today when I tried adding a little bit of e85 to some 91 octane and running map 3. Now all maps missfire including map 0. Did I add too much e85 or something. I will attach some logs

I did the same thing and now my engine is mis firing

I put a new sensor in and still have the same issue, so the sensor isn’t the problem.
