I'm not too sure its a skinny long box. Looks like the one you guys have on your anti-lag walk through.

Hey Dave, I was browsing the web and trying to dig deeper to see if anyone else has had this issue. Turns out on Boost Addicts Dave had helped someone else with a similar issue. Maybe he can chime in on the this but it seemed like the fix for the issue was the update the firmware on the DME. Apparently the old firmware on the DME is not very friendly to the 3.5TMAP sensor?

If you have the means of updating your dme/firmware itís worth a shot. What DME do you have?

Guys... I'm too close to giving up.. I'm honestly beginning to think about removing the JB4 all together and use MHD to get a tune.

I tell everyone to run jb4 with bck end flash.. Everyone I know that says throw out the jb4 I tell them no and that I'm sticking with it, however I cant get my car to run right with my 3.5TMAP and its getting to the point that I dont know what else to do and the support just isn't there.

I decided to email you guys directly for better support than waiting on the forum and the person helping just gives me vague answers. It's like hes not even paying attention to what I report back to him.

I sent in a log with the 3.5TMAP sensor plugged in with the jb4 harness and the 3.5TMAP option turned on as he requested. He saw something was wrong from the log. I advised him the car shows 8.9 psi of boost at idle and sputters when I give it gas.

He asked me to plug in the stock 3.5TMAP sensor and send him a log. Logically he log showed the car was running well. His response was "Well you are back on stock sensor now you should be fine"...

Again.. I need better support or I'm ditching this all together. I really hate to but I need my car to run right. I support you guys all the time I need you guys to support me over this issue. I seriously don't know what else to do here. I have logs of the car with and without the 3.5tmap sensor. Both at idle and some throttle in neurtal (car is not driveable with the 3.5tmap sensor option on).

Who have you been emailing with on our end.

Did you ever update your JB4 firmware?

Yeah everything is up to date. From the DME to the JB4

Frustrating for sure...

Why don’t we try this...

You could try removing the jb4 if you want, do you have access to a flash only map?

I can flash stock flashes using MHD which allow me to turn on or off the 3.5TMAP setting through there.

I have tried turning off the jb4 (setting 0) and flashing to stock through MHD with the 3.5TMAP setting turned on and the car seemed to be ok with it. However when I flash to stock once again but turned off the 3.5TMAP in MHD so that I could turn it back on in the JB4, the JB4 showed the same symptoms.

I'm assuming by unplugging the JB4 we'll be able to isolate the issue to the JB4 or my car?

What id do is remove the jb4, flash the car to “stock” WITH the 3.5 bar sensor option checked

We can eliminate a sensor / harness issue at that point if the car behaves normal

Ok will do! I work until late tonight and will work until 3pm eastern time tomorrow but can work on the car after work if not Saturday. I also scored a stage 2 fuel it pump that I will be adding.

I've seen this before in cars where customers try to rewire the stock connector themselves and damage the pins. I understand that you've returned back to stock orientation and are now using the BMS adapter but that may be something to look into.

Check PMS.

Yeah, itís not unheard of.

Flashing to stock flash + the n20 option checked, that will def. point us in a direction / give us some hard data

I checked the PMS and will give your method a try since it's easier than removing the JB4. (Try the easier stuff first)

I do have a question though, if damage occurred to the pins wouldn't it run rough with the stock tmap sensor as well? Not doubting you just trying to have a better understanding for things. It's usually when we're doing diagnostic work that we learn the most in my opinion lol

Not necessarily. I suspect it has to do with the enabling the N20 map sensor option, which rescales the MAP conversion tables.



Atmospheric pressure at sea level is 1 bar (14.5psi, on Y-axis). If you look at the voltage of the 2.5 bar sensor, its around 2v. Looking at the 3.5bar, 2v would be reading ~23-24psi. Around 8 psi difference, similar to the reading your JB4 is showing you.

*Just physically tested this on one of my cars. Removing pin the solid yellow wire (Pin #4 2.5bar or Pin #1 3.5bar) from the connector completely yields a reading of 13psi at idle. This is where I would start.

When you put it that way it makes sense! I'll be leaving work in about an hour and am going to try it out. Fingers Crossed I get the sucker working properly!

So I turned the ignition on and had my tablet next to me while swapping sensors.

When the 3.5tmap option is on I get 8.5psi on either stock sensor or the new sensor with the BMS PNP Harness.

Looks like the next step will be to remove the jb4

I have also tried to pry the pins slightly to make sure they are making contact. Sorry forgot to mention this
