    N2O TMAP Sensor

    Hey guys,

    Finally got our N2O TMAP sensor in. By this point it's old news but the sensor goes up to 3.5 bar and is a direct swap for our 2.5 bar sensor. Perfect for large turbo guys. To install it all you need is a connector adapter so the OEM connector plugs in along with a simple JB4 firmware update. Click here to enlarge

    For those interested we can sell you a PNP adapter for $25 so it's a direct plug in. Click here to enlarge

    I don't use PMs but you can always email me. For pushing the boundaries with large turbos we suggest a flash map with 12:1 air/fuel ratios, and around 10 degrees of advance up top. The Cobb S2+ Aggressive map works fine for that. Then you'll want the JB4 BT board along with this N2O sensor to really crank boost up especially in the midrange. You'll want meth with a flow sensor feeding that info in to the JB4. Our WW kit works well, but any kit with a 0-5v flow sensor signal is fine.

    Would 20+psi on RB's really only be beneficial on the dyno or track days? You can really only raise the boost that high with race gas and meth correct? So for street pump+meth this would be of no use..

    @dzenno could answer that, he is a cobb user, i think he made good power/numbers on pump/meth before

    It's hard to say. On pump+meth I think a lot more torque can be made down low than has been made thus far but then how much can your clutch hold?

    Very nice, yea the Cobb stg 2 agg should work, I just flashed back to Cobb stg2 after hitting 19.5 psi on stock turbos on stg2 agg! That's to much for stockers IMO

    I was hoping Dzenno would have posted some numbers with his revised map from Cobb by now

    So I am guessing Shiv ran into some hurdles with the new sensor? It has been a couple weeks since he got it. You know if he hit some big numbers on the dyno, he would have posted them.

    what about this statement in bold from Shiv?

Nonetheless, this is a decent starting point since we don't have any reasons to think that the n54 isn't stronger than the 4G63, stock for stock. If that is the case, the BMW will enjoy a 50% output advantage due to 50% larger displacement and 50% more pistons/rods. But still, it's a good idea to exercise restraint when running high midrange boost/torque pressures. Those looking to run 3.5bar map sensors just so they can run 22+psi of boost at peak torque might want to think twice Click here to enlarge

    We won't know for sure until someone really tries but my gut feeling given the rod shape is that RPM is going to be the killer more so than torque. I know VAC does offer stronger rods and pistons though, perhaps they can chime in with their view on it.

    Anyway if you want one paypal $25 per adapter + $5 shipping USA, $10 shipping intl (first class) to orders@burgertuning.com. Be sure your address is included in the paypal or Eric will curse you. Click here to enlarge

    Funny thing is the huge torque spikes midrange even on stock turbos with his tune yet he recommends against running big midrange power? Im not a fan of it for other reasons mostly transmission related.

    Do i need to state why i believe there are no updates, another sourced motor, and apprehension to 22+ psi? Of course, that with his "fuel upgrade" and not cobbs AFR control...

    Terry,

    Do these connectors insulate the wires? Noone wants to deal with condensation on wires entering the connector. Perhaps wrap them in a plastic shielding or shrink wrap?
    From all the things I've lost,
    I miss my mind the most!

    We've used the same connector system on maybe 5000 cars using the N54 JB+, N55 tunes, etc. You won't have any issues.
