    I am looking for the output curve of the 348 MAF

    If you have please share it :)

    I don't know what you are doing, but I like it already.

    I remember looking for these curves and I do not believe that they are out there. The easiest way to generate this curve would be with the use of a datalogger. A nice WOT run from 0-redline would do well, otherwise you will have to guess from some of the existing curves that have been previously published.

    You could easily generate a graph with a flowbench... or use an alternate MAF that provided you with the curve already (there are several appropriately sized MAF's that do this). Not that I have already investigated the topic.... LOL, We really should sit down and discuss over a few beers sometime.

    I would consider one of these curves, because I am willing to bet that one will be close.

    Plus you should read this:

    MicroSquirt® Introduction

    I should add that the best way of going about this is to actually datalog the sensor on the car with the intake system you plan to use. If you can't do that, then replicating the intake on the flowbench is the way to go. MAF curves are very sensitive to the intake tract design and can be messed with rather badly if the flow characteristics of the intake change dramatically from what I understand.

    If I can get the car finished and on the dyno by 4/4, I could possibly hook up my LM-1 to log a WOT run as well as driving to and from the dyno.

    Yes I seen that graph, the last big curve seems to correspond with what I found in the ECU

    I have an ostrich on the way to log data but dont want to wait


    Think I will set it up 15 % and down 15% and see what happens.


    Here is what I found
