    I'm noob, does the N20 sensor go in the charge pipe or intake manifold?

    Can you just plug it in and run it or do you have to change settings through ATR?

    Just replace the OEM TMAP sensor with the N20 one on the Charge Pipe

    I don't know if on the user end (AccessTuner Race) gives you permission to run higher than OEM allowed boost, but the PROtuners through ATP have been able to raise boost (and maximize the RBs/Vargas Stg 2s+) by using an adjusted TMap scalar.

    With the N20 sensor, I would not bother unless you're running a single turbo or larger than RB twins. For RB turbos they max out around 20psi so no real need for this unless you want to dial in 600#/ft of torque or something.

    But for anyone who needs it we have the PNP adapters to plug this sensor in for $25 + $5 shipping.

    Terry I thought the RB can go up to 25psi. No?

    At low RPM probably but then the trans can't hold that torque. I normally run them at 17psi down low, 20psi peak, and 18psi at redline, for a solid 500-520rw & 500wtq setup on E85/meth.

    Thanks. The car runs fine with the new sensor without any other tune related modifications?

    I had it installed in my CP then couldn't remember if it went there or the Intake Manifold and ended up uninstalling it. Never turned the car on so I wasn't sure it would work with the new sensor.

I knew about Shiv's hacked up Delphi map sensor from about a year ago when he posted it up on e90post but we really wanted something plug and play and/or OEM that we could just rescale the DME boost/voltage tables with and run with.

    After some research and realizing the N20 engine ran higher boost than the N54 we focused on that sensor. For those that can recall I hinted about something to do with the "N20" a few weeks back but didn't want to say anything else as we didn't know if it'd be as nice as we wanted it to be.....
    Decided to post here on this. On another thread you said the following in relation to the N20 3.5 TMAP sensor

    Click here to enlarge Originally Posted by dzenno@ProTUNING Freaks Click here to enlarge
    For the record the DME sees up to 22.5psi of actual boost with the 3.5bar map sensor in place. Right now we've got about 1.5-2.5psi on top of that through so called "cheating".

    The DME, and in turn transmission, both see max currently supported load of 220. We don't run stock load targets or below stock on the flash while raising boost on the piggy. This approach is not the way to do things in the long run. Its a way that works well enough providing full visibility into what the tune is doing while awaiting a boost limit removal change from the Cobb end.

    The only weakness exposed with meth is your posts about it. As a matter of fact, on the dyno last time while running on 91 octane and meth and hitting 600+whp we had HFS-4 failsafe trip due to its window (high/low) configuration. It caused all boost to be dumped as it should while the accelerator was still pinned to 99.x (all the way down) and throttle was wide open at 80.x% and actual boost drop without a single timing correction.

    Good luck with the e36. Just don't drop an n54 in it. You won't see much use of it at 12psi Click here to enlarge
    So if I am understanding this correctly, even with the N20 3.5 bar TMAP sensor that "allows" the DME to see max 36 PSI (50.76 AP) the DME is still limited to only seeing 22.5 PSI (37.2 AP) ? If yes, isnt someone working on a way to flash/edit the DME to increase this head cap ?

    My basic understanding is that the DME and all of its references for internal modeling were never designed to read past a load of 220, which is roughly 22.5 psi. It will require custom code, ala Cobb programmers, to find a way around this bottleneck and expand the DME's viewpoint past 22.5 psi.

    Figured as much. These boost limits are always PITAs. When I wrote the JB4 I used a byte to represent boost, so it can read up to 25.5psi currently. Sometime before I get the VT3 turbos on I'll need to go through all the code and change tons of stuff from bytes to words and then debug. Can't wait. =/
