Default Bosch 4 bar TMAP - 04-07-2017, 03:42 PM

Hey guys,

I'm having a really hard time finding this sensor.. I've ordered the adapter harness from BMS but can'd find the TMAP itself on the site. I found Terry's post where the had a kit for either the 3.5 or 4 bar sensors and adapters but can't find it on the site. Where can I order this sensor from? I search and all i find it aliexpress and Asian websites and I'd like to avoid buying a knockoff sensor.

Thanks!

I know the part# but like I said when I google it the websites that come up are selling knockoff sensors. There is this thread: http://www.n54tech.com/forums/showthread.php?t=36457

It says there is a kit in the upgrades section for $99 for the sensor and adapter. I only see the adapter in that section.

We stopped selling the sensors as batch to batch the quality varies a lot. I think somehow counterfeit ones were getting slipped in to our shipments. I kept enough on hand to replace anyone who bought one from us and winds up needing a replacement free of charge. And we are done selling them.

We will continue to sell the adapter ala-cart for those who want it and are looking in to more reliable 4bar-5bar alternatives. The bad news is they will likely be much more expensive.

I just installed my bosch 4 bar which I ordered from BMS last night. How can I tell if it's no good? Any tell tale signs to look for with the counterfeits?

Seems like most of the people who have problems with the 4bar are trying to run flash only. The flash tuners have not figured out how to implement the same sensor scaling we have on the JB4, for some reason.

If you get a 2ABC fault shortly after installing it then its faulty. They normally die quickly if they are going to. Normally if they are working OK they stay working and I've got plenty of spares for anyone who needs one. I have not found a way to tell which is counterfeit and which is real so decided to just stop reselling the sensors all together.

Cool, thanks Terry. So far so good with mine, I've put on a couple hundred KM of light driving (breaking in clutch) with no issues yet.

JB4 3.5bar and 4bar plug and play TMAP adapters

Use these plug and play adapters to quickly adapt a 3.5bar or 4bar
TMAP sensor to your N54, raising the boost maximum boost range from
20psi factory up to 36psi for the 3.5bar and 43psi for the 4bar. For
most applications the 3.5bar adapter is suggested which requires OEM
BMW sensor part number: 13627843531. For very high boost applications
the 4bar adapter can be used which requires Bosch 4bar sensor part
281002576.

Does the 3.5 bar and 4 bar sensor use different adapters? I have an adapter for the 4 bar and planning on installing a 3.5 bar and just confirming if I have to buy a different adapter also.

Often on startup I throw 2ABD Boost pressure sensor overrun. I clear it and all is good. I have had my 4 bar for about a year but this has only recently started. Its it likely a faulty 4 Bar?

Good to see Terry finally gave in, and accepted the 4 bars from Bosch were nothing but a bunch of trouble. Its not just the N54 either, on the ecoboost platforms 2 different manufactures starting having their own made due to issue with the 4 Bars, namely poor idle characteristics, and variance between sensors. Honestly never really got this big infatuation with the 4 bar sensors on this cars. Not many are running more than 36 psi, yet they would throw a 4 bar on it, and lose resolution. At this point if more than a 3.5 bar is needed just get a vacuum block, and run an AEM 5 bar.

That is likely a software setting. Email me for the latest JB4 firmware to see if it helps. If not we'll replace the sensor for you.
