MAP sensor?

[Jehtte]

So, according to Wikipedia(combined with my understanding), a manifold absolute pressure sensor is the way to go if you use BOVs. First of all, is this true? Second of all, where do I get them? I've searched a few performance part sites and Google pretty tenaciously, but to no avail. Any alternative suggestions? Thanks again in advance.

I am not expert however I do know you would need a stand alone ecu to run a MAP setup. I'm sure someone will chime in. You can use bovs with the stock MAF setup however the AFR will spike to the rich side when you shift.

MAP is not as accurate as a MAF for air metering. BOVs, IMHO, are ricey. The only thing they offer is the Psssshhhh sound. The stock recirculating valves are more than capable of handling even very high power setups.

MAP does require a standalone engine management system. Although you may be able to wire it in to a Nistune ECU, but I'm not sure. Best to search the Nistune forums to be sure.

MAP is currently no supported by NISTune but they are working on it, I personally wouldnt run MAP without MAF, its a double redundancy system basically if run MAF & MAP and are a good tuner, you could make the car do and sense anything so it would actually know when the BOVs were opening and compensate. The only potential problem I see with all this is that the ECU may be too slow with this many inputs, thats a potential problem i'm not a computer engineer and don't know whether this is enough to overload the ECUs capabilities.

you can tune the deceleration portion of the fuel map to compensate for using bov on a MAF system which any tuner can do, and some people like that sound, where others think it is ricey and unneeded but each to there own.

Informative. Should have done more of the right research. Didn't know she had recirculating valves. Well that answers all of my questions. Thanks again guys.
