megasquirt map sensor

i was wondering if i bought a megasquirt standalone to manage my engine cause i was wanting to turbo my klze. would i be able to get rid of the plunger style maf and use the map sensor that the megasquirt is able to use in order to run an atmospheric venting bov and not have to reroute it without it running rich everytime the bov blows off because the maf has already metered the air for the ecu. also if i do use the maf sensor to remedy the problem what brand sensor ie gm ford mazda would i use and where would i place it would i have to drill and tap something in order to gain the signal and how would i go about tuning it. i know thats a lot of ?s but just wondering any help would be greatly appreciated

I have 400kpa (4 bar??) in my Spectre EMS Pro unit (MS). Not that I'll ever be using that much boost.

Ya i had my wires crossed because it starts with the 2.5 bar sensor ans you can upgrade to 4 bar internal sensor.

Let me get this straight... a MAP sensor and meter the air just by reading intake manifold pressure?

Yeah, that's pretty much it since MS will be controlling your motor and it has the ability to use a MAP sensor. It's pretty straightforward.

Sort of. It uses a table in the ECU to estimate the air flow based on the MAP sensor reading and engine RPM, as well as corrections based on the air temperature.

IIRC it does that in conjunction with the IAT sensor, which reads the intake temps.

hey wuz up i need an answer with this so i was thinking about getting a megasquirt standalone ecu n this is the info on it
:

::::::::::::::::INFO
Professionally assembled megasquirt n spark, v2.2 PCB, MS1 processor, with base tune and code loaded for the listed cars. Hardware modifications have been made to the board to allow the use of the stock distributor with NO modifications of any kind necessary, just wire it up. This offers full fuel and spark control. I have the exact same ecu in my 400 whp Mazda MX3 v6. With this ecu you will get a labeled wiring harness, instruction and software CD, base map, and both GM coolant and IAT sensors. This offers complete control over your ignition timing and fuel curves for whatever modifications you may have. It is tuned via a laptop realtime. Please allow 6 days for handling.

so my question is would this work with the klze too ? or is it for the a-spec engine only the way is set up ? or will i have to go get it tuned to my ze engine ?

i have the ze an its a curve neck

iam new to this so if u guys would help it would b great

iam driving a 93 mazda v6 5 spd 2.5liter mx6 Ls help ! me plz lol
