Looks like a new sensor can you verify above pic that it’s the right number? I’ll re clean it again with mad spray.

Does 2ABD cause lean conditions? The funny thing is the logs say lean but plugs are black.

[DeepEddy]

I sprayed less then a seconds burst to clean, dont go crazy. U need to research what tmap u have and if its correct ,quick google search for n54 tmaps should help. If all else fails check ur wiring. Inspect the pins in connectors at sensor and dme.
BMW MSV70 MSV80 MSD80 NOx emulator 30EA 30E9 catalytic converter
Pinout will help u locate connections at dme.
9e and 10 e are two of the four wires I need to check.

[DeepEddy]

connector x60005
Wires = 9m, 10e, 17e, 31a
If u go to the link and locate connector X05 in reference to your dme. Those four wires are for ur tmap, if u know how to test continuity u can make sure ur harness is good , physicalinspect connections

[DeepEddy]

Google for tmap part numbers if ur unsure

Will check. Ok so crazy thing is I started car I took the charge pipe sensor out and car didn’t change idle or anything. Ahh that can’t be right.

I see there’s a bunch of different ones. I uploaded the one I have on there. Also my load at idle is 30% and tps is at 12% that seems way too high.

[DeepEddy]

If its a lose ir broken connection that would make sense. Something corrupt with ur mhd or bad dme. I had a failed msd80 twice, failed connections and bad sensors, failed magnet in my master cylinder and countless and ongoing oil leaks all were a pain to trouble shoot or repair.Most off us here deal with JB4 and mhd for bef Instead of straight mhd. Dont give up, dont get tunnel vision , and think outside the box.

[DeepEddy]

3.5 and 4 bar tmaps are from other bimmers that we upgrade so we can read more boost then factory tmap. Check ecstuning.com for factory sensor numbers

[Bmw335iBeast]

I have a new T map ordered from the factory.

Funny thing is I don’t know what the shop was thinking but they did say they uploaded MHD and took off the Jb4 is it possible the MHT is still installed but the wrong team app number selected?

Is that odd that when the car is running taking out the tmap sensor from the Charge pipe that the car does not run rough?

Now if I take the intake sensor off the manifold why the car is running it stalls out.

Also do you think the load and TPS is correct it idle that seems high the pic I have above.

Also how can we check the dme to see if no tune is flashed?

[DeepEddy]

Mhd can be. BEF ( back end flash) to supplement the jb4 or MHD can be used to just flash the DMe with no JB4. U may need to get ur own MHD app and purchase the license. Then u will be able to flash back to stock on the dme, troubleshoot and get ur car running right and only then worry about JB4 and mhd flashes for More Power depending on personal preference and power or tuning goals. Get ur self to stock and running right FIRST!!!!

That’s what I’m thinking. They said they got it back to stock but somehow I don’t think so. I have a shop that can check if it is stock the dme.

How about the load and tps at idle. Is that correct?

[DeepEddy]

Its not the dme (ecu) that u need to confirm is stock. U need to confirm the flash or program ur engine is running that has to be stock. MHD is used to remove the BMW's program that makes ur engine run and upload a tune. In this tune parameter can be changed like for example a selection of stock, 3.5 bar or 4 bar tmap sensor. If the dme has a 3.5 bar or 4 bar programmed and u have a stock one installed u will run into issues. U need to bite the bullet download mhd, buy a dcan cable from burgertuning.com and pay for a license. This will allow u to connect to ur dme and either flash the computer back to stock or any of the shelf tune u pay extra for. But from what in understanding is a shop is telling u something and u have no clue it that is what u car says.

Maybe just pay the shop to repair it for you?

If tuning, and enjoying this platform is a goal of your for a prolonged duration u will need to invest in specialty tools and gadgets to accomplish this. Or have some deep pockets.

Ok I got a better scanner. Here are my codes.

Also interesting read out watch fuel pressure start high then drop hmm. So still thinking mhd is installed on ecu and a 3.5bar map was selected unfortunately I can’t get to it to change it so ordered a 3.5bar sensor.

Check a log. Fuel pressure when boosting is 1318 then drops down to 1100

[Bmw335iBeast]

Another log with short terms.

[DeepEddy]

Don't forget the adapter harness as connectors are not the same. Did u purchase MHD with a license and either a Bluetooth or DAN cable?

Absolutely. Also what did u think of the logs?

Lol already reversed the 4 wires.

[DeepEddy]

Got get some one to chime in on that, especially that those are a bit odd consideringwe here are used to jb4 logs. Might want to consider purchasing a jb4 and use mhd for bef. There goes the dam sales pitch again

I already have the Jb4 installed on car lol. Just a different log.

[DeepEddy]

WTF?why are u posting those logs then not enough info. And pretty sure someone else would make it worth there time to look and chime in
