Upgrading TMAP Sensor

Has anyone upgraded their TMAP sensors to 3.5 or 4.0 Bar to allow more boost.

You cannot do that without reprogramming the DME. 3.5 bar is = 50psi - don't you think that is enough for you?

Sorry - misread that. PTF will have support for 3.5 TMAP soon I believe otherwise you need to go JB4.

i have been trying to successfully tune my car for a while now using BM3. When WOT at high rpms with anything more than 18-19 pounds of boost the car dumps fuel. So thinking going to 3.5 bar TMAP might help

On some of our N55 tunes we reflash to use the 3.5bar sensor if running above 20psi. Technically the 3.5bar sensor reads up to 50psi but after you factor in atmospheric pressure which is ~1bar the positive pressure cap ends up being just over 21psi for the 2.5bar sensor and just over 36psi for the 3.5bar sensor.

The tables are there on BM3, but are you sure you're not running out of HPFP?

I'll bet if your running near 19psi consistently then you would be over working the HPFP without an upgrade. Do you ever get a 11A0002 code? I wold hope this is being discussed with Dzenan & Halim and they are presenting an solution

Never got that code. And yes we are trying to figure it out with them and my tuner

HPFP crashing for sure, get a log and you'll see HPFP Actual is under 1900psi while Target is higher yes?
These cars will run out of fuel after 18psi in high rpms unless you supply fueling via PI or Meth
Try the latest OTS map and see how it does not crash the HPFP
