I already found part of the info I needed by getting into the ECM tables. I also found the 30 to 150 Hz range in the Trouble codes section on gnttype.org. But.. I have a couple more questions. How does the "count" in the MAF tables relate to the frequency of the output? It appears to be about .1Hz Does that sound right? Why is there 6 MAF tables? Why do they max out (255 gm/sec) where they do (count 1472)? Sensor or ECM maxing out? Sorry for all the questions, I am a newbie, with an EEET background, and am considering building a SIMPLE MAF X-lator. I plan on doing my tuning within the ECM and don't need all the functionality (or the expense) (or the ugly box under my hood) of what is currently available.
Thanks
Bob
P.S. What MAF are you all using (LT1, LS1, Impala SS) and why? Is the size the biggest factor?
