New to programming, MAF. advice? Tips?
First off, I have read the tech article on this board. I am soon going to purchace the hardware/software to do this stuff.
Some Questions..
How do you hack the 255g/sec max value in the ecm?
I don't know about the stock MAF, but will the SU-145(Wells) MAF produce a larger value than 255g/sec. This MAF will flow somewhere in the 700-800CFM range.
Does the MAF send its data to the ecm as varying voltage or varying frequency?
I was reading through some other posts and noticed someone had mentioned that the MAF (165) ECM's prom is maxed out and can not hold any additional info. What is the deal with that.
Any other tips or advice you experienced guys can throw my way would greatly help.

82' Z-28. 327" w/ flat tops. 216/228/112LS. Pocket ported 041 heads 1.94/1.50 SS valves. World Class T-5 from a 91'. Best run? Runs with 2001 vette to 150mph!
